If the offices in the building found out he could fix all their faulty devices then they would come to him to fix them instead of chucking them out. He'd be shooting himself in the foot.
Reminds me of how I fixed a Linksys SRX400 router once. It stopped functioning, so I opened up the board and started running my fingers across the circuits while the device was powered. On one occasion the unit came alive. I repeated the process a few times to confirm it wasn't a fluke. I noticed 2 traces with which my fingers were making contact. Measured my skin resistance with a multimeter, found a matching potentiometer. Soldered it in between the traces and got 2 more years of life out of the router.
This is the tech guy's equiv of using a wire coathanger, folded into the shape of Australia as an antenna.. But then again, a dumb idea that works is not a dumb idea..
@@PRiMETECHAU Indeed. I knew there was no risk to me and I wasn't afraid of zapping the router since it was already technically dead. The whole point of inspection is to see if anything burned out, or heats up, indicating a short. Not like I was planning on doing the fix all along. I just wanted to have my internet back without having to buy a new router or wait a week for some replacement chip from Digikey.
18:18 I'm gonna reiterate something I read online: "The next time you have trouble with your computer, remember that it is just a rock that we tricked into doing math."
The mainstream Intel chips at the time had a few issues with the hardware for the clock generation on the LPC bus that was used for low bandwidth I/O like TPM or embedded controllers. I recall it was a problem bringing it up from a low power mode after sleep or something. We mostly fixed it in firmware by disabling the sleep mode for that, I guess Atom didn't have the ability. (We = the BIOS developers at Intel)
The great part of mainstream Intel chips (laptop / desktop) is that the BIOS isn't loaded over LPC, but over a dedicated SPI interface, so we could actually fix it in software. If these Atom systems have BIOS on LPC, you're SOL.
i was wondering why an LPC fault would affect the boot flash! every desktop board i've seen in the modern era uses SPI flash for firmware. didn't know Atom used LPC for that
Thanks, Dave! You just enabled me to revive my DS415+. I thought the electric storm the other day blew it out, and since there were blinking yellow lights for one, then two, disks, I also expected to need to buy new drives. And with today's scandal with WD Red drives (SMD vs CMT or some such rubbish), I was not happy. But now I'm up and running, all drives were okay, and I even managed to find a 1/4W resistor in my stash (1981 vintage) to perform the repair. The 121GW pegged it at 103 Ohms, not bad for a 10% oldie. Cheers from Texas!
My 415+ developed this fault Dec. 20, after more than 5 years of use. It’s now working again thanks to this video. $$ saved and e-waste reduced !! Thanks so much for the content.
Hello! Just wanted to let you know my 415+ stopped working 2 weeks ago. Then I found your video, ordered the resistors and the bios battery and just finished the repair. Worked like a charm! I can connect to the web interface again and all my data is still there. Thank you very much! #righttorepair
Thank you so much for this video!!! I've been using a Synology DS415+ since 2015, running 24/7 loaded with 4x 4TB drives. Yesterday (01/16/2022), for no apparent reason, it dropped off the network and I couldn't get it back. After a few reboots, I go the solid orange disk lights with flashing blue light. Completely dead. After doing some Internet research and finding this video, I took DS415+ apart, soldiered the 100ohm resistor across pin 1 & 6 and wow...it's back online! Wonderful! Thank you for the great instructional and explainer video. Saved me $$$ to replace my NAS (at least for the time being).
We have had two of these exact model working at our school for years now and they have been great. Not to worried if they fail because they are only sync backups but good to know about the fix. Thanks
It may have been used, but looks brand new. The system software is stored on a small partition on the disks in the trays. The small DOM you saw inside the unit contains the rescue partition, which basically allows you to access it to set it up. If you try and set one up with no disks inside, it'll complain, as it has nowhere to put the Diskstation manager. In fact, if you're upgrading to a newer model, you can move the disks from the older one to the newer one, and after a repair, which basically changes some configuration files to suit the new Diskstation, it takes on the identity of your old one, including all the settings, just with the new model number and additional bays.
I have always been jealous of your dumpster finds...until today, when I found a Recordex 330-II 1-to-3 *stereo* cassette duplicator. Needs new belts and probably caps, but the housing and mechanism is near-perfect. My hipster cred is through the roof.
I've not been too jealous. My top 5 dumpster finds can rival even his 1: Roland Juno 60 Synthesizer...fully functional, but with no patches in memory 2: Nvidia GeForce GTX 780 5: RUNNING Husquvarna Weed Eater 4: Sanyo 55in Plasma(don't remember the model) 5: Asus RT-AC66U
Just had to RMA a 1515+ that's been in constant use for over three years, just started randomly rebooting. Was quite surprised to receive another 1515+ as a replacement
I got an older cousin, the DS414(Marvell) and it's a frigging Rock. It's been through a lot with me, two major evacuations, new drives, and a lightning strike (she got replaced, the drives are still good)! It's still running backups even as we speak, it's got another drive developing bad blocks. I'll wait until it gets to about 100 or so, before swapping it out. Go get some 4TB WD Reds or Seagate Iron Wolf NAS drives and load her up. She looks a damn sight better inside than mine right now. She needs a good dusting out.
The daughter card is a standard USB disk on chip. Basically a thumb drive but the header is designed to fit directly into the USB IDC connector on the motherboard. It's common in a lot of x86 based networking products.
I did the same resistor fix with two different ds1815+ . They both lasted 6 months or so, before dying again. Before the C2000 bug, I had 3 power supply failure too on the same devices... I still consider synology one of the best brand in the business... but damn, what a huge pain in the arse
This issue just popped up this morning after 7 years of continuous service, and I found the "100 ohm resistor fix" on a number of blogs/forums/etc but I was dissatisfied with the general lack of explanation of what the actual problem was or why this fix fixes it - I dug a little further and found your video which not only satisfied my curiosity but also served as a friendly companion while I played along at home. Thank you!
seconded or thirded! i mean, i had a laptop for a good 8 years that literally had a jack from another laptop hanging out of the kensington lock port via a red and a black wire powering a IBM thinkpad from a dell/hp charger
Maybe a year ago I did a similar "repair" on my and my friend's DS415+. Friend's unit was in a similar state shown in the video (blinking power led and solid orange disk leds) and it was resurrected. My unit was fine because of a lot lower use time, but I just future proofed it. Still, it sits in back of my head that this will happen again, so I don't run my unit 24/7. My friend just shelved his unit deeming it not reliable and switched to QNAP, which also failed after around 18 months (different reasons of course).
Yep, I've got a Cisco ASA 5506 firewall that was on that list too, but it hasn't failed yet. Although I'm pretty sure the failure mode is on reboot (like you said, LPC clock is mostly just used for the BIOS boot ROM), so the fact that I'm running it on UPS and it's almost never rebooted may be why I haven't seen it fail. For all I know, the LPC clock is dead as a dodo, and this thing is one reboot away from following suit. It's fixed on newer revisions, so I'm curious whether they've just done a resistor bodge, or if they've re-spun the boards. Cisco does offer proactive/post-failure RMA for in warranty units, but their field notice suggests failures begin after 18 months, so they that's conveniently out of the statutory warranty period if you're not paying attention. Thankfully Cisco can sell you a service contract which would also allow RMA.
I don't know if Dave has re-stocked, but there was a time, when he made this video, at least, that there was one common electronic item that I had that Dave didn't! LOL
the reason you may have thought it had not been setup before is because the synology os actually creates a partition and runs on the hard drive(s) so in your example if you swap that single hdd with a fresh one you would have to setup dsm again. The synology in a diskless state only has small on board storage. Keep this in mind if you want to swap 4 new larger drives or 3 new and a ssd cache. Depending on your raid config you can add 3 new drives and once they have initialized and join the pool you can swap out your original first drive without losing your data and config. But in your situation it doesn’t matter because it’s a new setup anyways.
I have a ds1815+ and it has the 100ohm c20xx fix installed from the factory. The next common bug with the 2015 synology nas's is that when powered down they will not power back up. One fix to that is to solder a 1000ohm resister between pads at the Q4 transistor. That unfortunately did not fix my nas. By the way Synology, knowing these nas's were defective, happily replaced mine every time it failed (four times in total) until the warranty of course expired. Then they tell you can can save your data (60TB in my case) by buying a new $1000 DS1821+!!! I searched and searched for a solution to the no startup problem and came across a suggestion to simply short the connection between a green and black wire in the 24 pin connector (the 3rd and fourth pins from the right side) and the nas would boot. When I did this my nas powered on, to my surprise. I did not like the idea of power off though by simply yanking the power cord, so I installed a switch. To power on you just close the switch and to power off you do a normal shutdown from the menu and when all the drive lights go out you just open the switch. It scrubbed all the drives and has been working ever since and I saved blowing $1000 on a ds1821+! Here is a picture of the fix... imgur.com/a/TdHTAE8
I'm sure you're right about the P-FET failure. It's probably in a hot spot on the chip or something equally mundane. The series resistors adds a little extra inductance that might affect the clock shape some, but 25 MHz and no obvious overshoot minimizes my concern about that. A stiff pull-up will stress the N-FET complement some, but I would use it for non-essentials. What are the chances that the drives can be read in another NAS if this one failed?
Fixed my personal DS415+ about 18 months ago, and luckily it is still running 24/7 today. I also happen work in networking and had to replace a bunch of Cisco routers and firewalls that were affected by this bug. Thanks for the video!
How's that DS415+ holding up? I'm about to do this fix and want to know the potential life I can expect (got the DS with 4 x 4TB drives for $700 so not the worst but I just finished moving all my data and after the unit crash I did a power cycle and then she died)
I recognised this problem from the thumbnail! I had this problem with my DS1515+. I think it’s the LPC bus that physically degrades so it stops booting the BIOS (if it’s hosted on the LPC bus). Synology didn’t disseminate any information regarding the issue despite my registering the device. I even tried claiming a repair on the warranty, but was told there was nothing they could do. They acted like the problem didn’t exist. Maybe I was just too new to the party. The resistor has fixed it for me (after mine stopped working) and it’s still working about 3..4 years on. Very disappointed with how Synology and Intel handled this one considering a NAS is meant to be rock solid and reliable.
@9:50: i suppose there is an bootloader on flash memory with some compressed data. When you put some hdd, bootloader can extract all data on hdd, so you'll have an fully operational nas. It happened to me on both nas i have.
The year is in the synologys modelnumbers. Like DS4(the number off drives)15(the year, and no it´s not 1915 :P ). Pretty handy when looking around ebay and the likes for older/ceaper hardware.
The first digit (or the first two, in some cases) is actually the maximum number of drives the device can manage, including one or two expansion cases of 5 drives each, if ghe DS has ports for them. Which explains numbers like 7, 15 or 18.
I have a first gen Drobo that still running with four Seagate ES.3 type drives installed. I've owned it since 2007. I've another one I got in 2014. It is also running perfectly.
Two days ago e "repaired" Synology RS2416RP+ Rack mounted 12 drive unit just the same way Undergoing copy of the 24Tb of data right at this moment :) So, in case anyone needs this, It does affect bigger models also, and the solutions is the same. (The pads are on a different part of the board, but you cant miss it, they look the same)
ok great, I think synology also had these atom C2xxxx series inside there 19" rackstations and there fore they are also affected by this hw bug.. ? so perhaps than this resistor fix will also work the same way for the DS1515+ DS1815+ and some other models perhaps.. ? Im still wondering then if this transistor fix is permantent, or only slowing it down and still make the atom chip to work.. ?
@@floorinterfacing1582 The RS2416RP+ has an Intel Atom C2538 and i can attest that it has the same problem with the same "solution". As for the DS1515+ DS1815+, i really don't know. I'm however not using the storage in production anymore, even thought its for data that is "better to have and not need than need and not have". I'm changing the sucker.
That porch reminds me of tristate logic. The porch is around when the chip select would be driven in some circuits, it's been quite a while since I looked at it.
Intel has come a gutser so much in recent years, the SpectreNG & LasyFPU vulns were fun with fixes that broke more things. That one made some fun days at work.
@EEVblog I'd just power it from a laptop power supply + dc-dc ebay converter or one of the 200 ATX power supplies that you have floating around. Drive wise, I'd look at shucking external 3,5" WD Drives, since they contain white labeled WD Reds.
Not guaranteed they come with white labeled red's, some are just white green's or blue's either. You can't know upfront and wd won't tell you because they don't want to be stuck to using only a single type for their external enclosures. As far as I heard though the mybook duo's come with obvious red's in it (same model number as retail, the above mentioned mostly have slightly different numbers which may indicated a slightly different firmware), maybe just because those are two in a single enclosure and wd wanted to make sure they work without issue
@@djunia4u Yup, the Synology NAS do the same. They have a basic built-in boot environment that gets you through the OS install process, then boots off the HDDs.
I am going through this now with a Synology DS1515+ with the Atom C2538, It started with the Synology randomly rebooting only between 4am-7am (never in the day) and then it dies. Going through warranty replacement at the moment. I also have an RS2416+ which I am quite reliant on with the same CPU, hopefully, I do not get that issue with this one.
A little update on this, Synology sent me a brand new unit today. Has the same CPU but it is a brand new unit, so I guess it already has something done to it to rectify the issue.
I saved one of these exact units from the dumpster when I was charged with building a new office for my small firm! I quickly sequestered it into my "cool crap to work into the home lab" pile. This was along with two T130 servers. Haven't decided what to do with them yet. Excited to watch this video...
Thank you! I have an Atom based 4bay Netgear Readynas sitting broken in a similar way, waiting for some time when I get a clue what might be wrong. I will take a look if I can find a similar solution for the Readynas.
Nope, my unit uses a different CPU (older Atom D410) and I can't find similar solutions to Readynas. And the thing seems to have an dedicated oscillator. And it uses a non-standard PCI-like connector to the backplane, so I can't even reuse it in my PC :-(
Dear @EEVblog, I am going to disassemble my NAS, to put it into a 10inch case and wanted to ask you if you think it is possible to use a pci extender for the harddrive pcb?
......you poor poor man, i feel synpathy for you, this can not be a easy job, it isnt just old grandmas that are like HELPPPPPPPPPP MY SERVER IS DOWN its more like, "rich" corperate business owners who expect you to fix everything instantly and still act like old grandmas when it comes to tech "why isnt my usb flash drive working" "sir, that is the floppy disk drive, do not insert usb into the floppy drive"
Hello I bought 10 resistors for 2.81€ on ebay and solder one to the board like you did and tada, NAS is back online. My boss will be glad to know that ! Thank you for sharing :)
I'm not an electronics guy, but I know how to do a little soldering. I bought the 100Ohm 1/4w resister and I'm just wondering, does it matter what direction you place it when you solder it in, like a one way door, or does it not matter like a two way door? Any help would be appreciated.
I figured it out since no one answered, I'll post the answer for a future person trying to do this. Generally speaking, no, the direction of the resister doesn't matter. It more or less depends on the circuits around it. However, since I didn't know the circuits around it and if that was relevant, I did find a video using a single 100Ohm 1/4w resister instead of the two like in this video and the side of the resister with more striping goes toward the pin 1 position. Anyway, I soldered it in place, replaced the battery and viola, my DS415+ is back up and running and will now serve as a backup to the new DS920+ I bought to replace it. This video was helpful though, and this fix did work.
Youpie! I found DS415+ in the "for secure liquidation" bin on my employer two days ago. Sure enough, once powered, it was flashing blue led and keeping all disk indicator leds lit. Today, I have installed the resistor as instructed, and to my surprise (and great pleasure), the device booted up correctly. In the meantime I reset the settings to defaults so it is now detected by SL assistant tool in my network! Seems to work fine! Thanks for the great piece of info.
My father had a wd nas thing, and it stopped working. It turned out the discs had a load of bad clusters. I tried to figure out how to raid them into a filesystem. In the end, I used the 'foremost' utility in Linux to try to get mostly the pictures off of it. Problem is all the larger pictures were like chopped off 80% down the screen. Don't know if I still have the boards or not.
My 415+ "died" a couple of months ago, of course just a year out of warranty. I had no bloody idea the Atoms in these had this problem. Luckily I came across this resistor fix on the Synology forums and it booted right up again! Wish I had known this sooner so I could preemptively apply the resistor to slow down the degradation. I wonder how many years the resistor added.
The flash board actually looks like an eUSB, which is used in a lot of products, it's very convenient. The storage connectors are actually SAS connectors and not SATA, does synology DS support SAS drives?
I was effected by this C2000 bug too. It was one of my server boards. It runs for month and after getting it off for service it not came up again. The manufacturer just repaired it with a simple RMA process, especially created for the C2000 bug. It was really a big thing in industry these days. It effected a lot of systems: Network switches, routers, storages, low-power servers, and so on...
Any chance there's a variant of this fix for the DS1511+ ? it's a completely different board, but I do see a 12 pin on the board that MIGHT just be the same thing.
Cant thank you enough... my DS415+ died on my a few months back , I bought a more recent one and kept this one it its box, I wanted to sell it for parts and then I just googled a few things and found your video... followed it to open the box, went to buy a 100ohm resistor, installed it and... ITS ALIIVE !! I cant believe that Synology actually told me it was dead, they must know of this fix !!
I had a PfSense router that suddenly failed. Likely the same issue. I wonder if it would be possible to locate a place to add a pull-up on that board? Does Synology work without the Klowd? After a Seagate backup drive that wanted you to create an account, I'm trigger-shy about buying these backup devices.
My DS415+ died of this bug too. I got a replacment unit from Synology (like 2 months after RMAing). I could not wait this long because I had to access my data and thus bought a DS918+ as replacement unit. So I got a spare "unused" DS415+ sitting around...
Wow, dude, you might have just saved my bacon. I have a 1515+ which uses the same CPU, and is quite an early batch so it probably has this problem, but it's far out of warranty. I think I'll pre-emptively apply this fix! I like these devices. I can see why people say they are over-priced, in a sense they are, but if you just want something and you want it to work with no fuzz, these are great. Well, except when they have buggy Intel silicon I suppose... But other than that ;) Mine is 6 years old and going strong otherwise, running 24/7 most of that time. Here's hoping a 100ohm resistor can add some more years. Also, you asked in the video - getting the install prompt does not mean the NAS was never used - the way these boxes work is they actually install and run their OS from the users harddrives. So, since the drive was unrecognized or blank, it had to install OS from scratch from ROM and set up anew.
@@z352kdaf8324 Sure, I don't see why not. The fix doesn't actually "repair" anything, it simply prevents the failed hardware from blocking the system boot process. The failed hardware in question isn't used in the NAS and thus the failure doesn't matter in and of itself.
Hello, my synology rs2416 is not booting after dsm update. The blue and orange lights are on. I think I'm having the same problem. How long does putting 100 ohm resistor to the solution solve the problem?
On first glance that unpopulated connector you used for the mod looks kinda like a TPM header. That also has the LPC bus wired up to it, and could possibly be something this motherboard might like to have in a different design variant.
I've got a Supermicro NAS with a C2758 in it - stopped booting one day, got an RMA for it and Supermicro started talking about a $150-300 fee. Sent it back and Supermicro went very quiet - then it came back from Taiwan via express freight - all working, with an (as of then) unreleased BIOS update. The note said "EC update" and no payment was required...
@@resneptacle That's the thing. Those stickers are usually placed so that you'd have to tear them in order to get whatever out, thus proving that you did. 5:34 Nothing happens to that sticker when you remove the stick. Weird.
It's a SODIMM RAM module. I upgraded it in my DS416play the other week. The sticker is still on it, they couldn't be the wiser if I put it back. Though the void period is long gone now, so it is moot for me.
@@Okurka. Stop propagating that myth. The warranty WILL be voided if the company wants the warranty voided. Period. Laws don't matter, you don't matter. The only way to get a company to fix/replace the item you've been into its to take them to court. (Or possibly have an attorney send a letter to them, which will cost $100-200. So not usually worth it.) You calling them for warranty work and sawing, "Hey... You... The law says..." It's an absolute dead end.

@@pelic9608 that's what's so infuriatingly curious about it - if they had wanted to stop you upgrading the ram, they could have taped it down with the sticker, so you can't remove the ram without breaking the sticker. Maybe some reverse psychology to catch eternally curious people like me XD
I would trust it enough if you can pull out the hard drives and connect them to a new nas and recover the data. I think it isnt more likely to kill your hdds than any other nas, most likely it would just stop booting someday.
Good evening, Amazon S3 Glacier may be a very good offline or like backup. Restoration takes few hours up to 24 hours, thus costs are very very low and delay is good for a safety backup. Regards Jean-François Simon
Well opamp outputs have a pull up and pull down transistors on their output. If the pull up transistor or it's drive circuity fails than the signal will not rise much over the low level voltage...
At this point hardware manufacturers looking for a free design review for the next iteration would do well to drop the prototypes in Dave's dumpster room (if they aren't doing that already).
I don't know about the fix. But I have a Synology DS412+ with 4 1TB WD red drives and only had one problem due to not doing the OS updates. I got that fixed by just removing all the drives, putting in a temp drive to get it booting. Then updated the DSM software. Then putting the original drives back in and then DSM updating the copies on the drives. Didn't lose any data and It is still running today. Also If encription is not enabled you can pull the drives and connect them to a linux computer or run a live flash drive that has mdadm and access the drives. How to read Synology models for NAS units DS = Diskstation (desktop model) RS = Rackstation (server rack mount) DX = Desktop Expansion unit (Connects to compatible units through ESATA cable, drives can be raided or JBOD in expansion but not mixed to raids in DS unit. So a raid can't use drives in both like 2 drives in DS and 2 drives in RX for Raid5. Can only Raid5 in just the drives in DS or DX for two pools. RX = Rackmount Expansion unit. (connectors allow rack expansion unit to be seen as part of RS unit to allow drives across both units to be raided together. ) RP after model number = Rackmount with replaceable power supplies. Example RX818RP+ has 2 removable power supplies, while RX818+ just has one built in unit 1st number = number of bays * DS415+ four bay = 4 DS218 two bay = 2 DS718+ two bay but can attach expansion unit =7 * second 2 numbers is the model year DS415+ means it's from 2015 but may have been sold till the next model like DS417 is release. Slim = smaller units that take laptop/ ssd 2.5 inch drives only. DS419Slim Play = includes faster CPU and/or more memory for transcoding video + = faster model compared to another model of same name being sold J = lower cost model of another model of same name. Example you can have 3 models name DS218, DS218+, And DS218j but different specs. There are more but those are Enterprise rackmount storage units.
The explanation for this find might be rather simple. Synology refuses to provide parts or any repairs to the units, once they come out of the warranty. Refuses, as in - you cannot pay money to get any authorized repair. So, once the warranty runs out, boom, they will direct you to just go out and buy another unit. If they feel gracious, they might throw you a bone and give you some tiny discount.
All the units replaced under warranty had the resistor mod that i have seen.

i was wondering why an LPC fault would affect the boot flash! every desktop board i've seen in the modern era uses SPI flash for firmware. didn't know Atom used LPC for that
Thanks, Dave! You just enabled me to revive my DS415+. I thought the electric storm the other day blew it out, and since there were blinking yellow lights for one, then two, disks, I also expected to need to buy new drives. And with today's scandal with WD Red drives (SMD vs CMT or some such rubbish), I was not happy. But now I'm up and running, all drives were okay, and I even managed to find a 1/4W resistor in my stash (1981 vintage) to perform the repair. The 121GW pegged it at 103 Ohms, not bad for a 10% oldie. Cheers from Texas!
My 415+ developed this fault Dec. 20, after more than 5 years of use. It’s now working again thanks to this video. $$ saved and e-waste reduced !! Thanks so much for the content.
Hello! Just wanted to let you know my 415+ stopped working 2 weeks ago. Then I found your video, ordered the resistors and the bios battery and just finished the repair. Worked like a charm! I can connect to the web interface again and all my data is still there. Thank you very much! #righttorepair
Does it still work? Mine died the same way 2 years ago or so and just stumbled on the fix this morning.
Thank you so much for this video!!! I've been using a Synology DS415+ since 2015, running 24/7 loaded with 4x 4TB drives. Yesterday (01/16/2022), for no apparent reason, it dropped off the network and I couldn't get it back. After a few reboots, I go the solid orange disk lights with flashing blue light. Completely dead. After doing some Internet research and finding this video, I took DS415+ apart, soldiered the 100ohm resistor across pin 1 & 6 and wow...it's back online! Wonderful! Thank you for the great instructional and explainer video. Saved me $$$ to replace my NAS (at least for the time being).
clock signal is negative(grounded) and pullup via internal diode. when diode is gone there is no more positive voltage
Greetings: Use a 1K trimmer to vary the pull-up and watch the clock variation.
We have had two of these exact model working at our school for years now and they have been great. Not to worried if they fail because they are only sync backups but good to know about the fix. Thanks
It seems like if you mod them now, then the CPU won't degrade as quickly.
It may have been used, but looks brand new. The system software is stored on a small partition on the disks in the trays. The small DOM you saw inside the unit contains the rescue partition, which basically allows you to access it to set it up. If you try and set one up with no disks inside, it'll complain, as it has nowhere to put the Diskstation manager. In fact, if you're upgrading to a newer model, you can move the disks from the older one to the newer one, and after a repair, which basically changes some configuration files to suit the new Diskstation, it takes on the identity of your old one, including all the settings, just with the new model number and additional bays.
My old 1998 workstation has a few tantalums rattling around in it. Every once on a while, one fails and desolders itself off the PCB.
Fantastic! Very helpful! Restored our DS415+ to health in about 30 min. Very helpful, particularly the tricky case disassembly.
I have the exact same NAS. I have done the fix on at least 5 of them so far.
Does the fix hold up. Or do you think it will fail over time?
Thank you for this video, my Synology DS411+II had the same fault so I took it apart today and adding the resistor fixed it !
I fixed my 415+ today following this video. Thanks so much, everything is up and running again.
I have always been jealous of your dumpster finds...until today, when I found a Recordex 330-II 1-to-3 *stereo* cassette duplicator. Needs new belts and probably caps, but the housing and mechanism is near-perfect. My hipster cred is through the roof.
I've not been too jealous. My top 5 dumpster finds can rival even his
1: Roland Juno 60 Synthesizer...fully functional, but with no patches in memory
2: Nvidia GeForce GTX 780
5: RUNNING Husquvarna Weed Eater
4: Sanyo 55in Plasma(don't remember the model)
5: Asus RT-AC66U
Just get a Meanwell power supply, they are about 25-30 USD for that amount of power
Did resistor fix on my 1815+. 2 minute fix and works like a champ.
any idea if the 1817+ has the same issue?
Just had to RMA a 1515+ that's been in constant use for over three years, just started randomly rebooting. Was quite surprised to receive another 1515+ as a replacement
I got an older cousin, the DS414(Marvell) and it's a frigging Rock. It's been through a lot with me, two major evacuations, new drives, and a lightning strike (she got replaced, the drives are still good)! It's still running backups even as we speak, it's got another drive developing bad blocks. I'll wait until it gets to about 100 or so, before swapping it out.
Go get some 4TB WD Reds or Seagate Iron Wolf NAS drives and load her up. She looks a damn sight better inside than mine right now. She needs a good dusting out.
The daughter card is a standard USB disk on chip. Basically a thumb drive but the header is designed to fit directly into the USB IDC connector on the motherboard. It's common in a lot of x86 based networking products.

Thats why i only like manually focused cameras. Not autofocus ones. Theres a lot of them out there.. really annoying

AvE?
no actually, this is 100% pure original dave, even if he has been referencing ave! he has been saying it right along for atleast 500 videos!
I did the same resistor fix with two different ds1815+ . They both lasted 6 months or so, before dying again. Before the C2000 bug, I had 3 power supply failure too on the same devices... I still consider synology one of the best brand in the business... but damn, what a huge pain in the arse
Thanks
I second this
This issue just popped up this morning after 7 years of continuous service, and I found the "100 ohm resistor fix" on a number of blogs/forums/etc but I was dissatisfied with the general lack of explanation of what the actual problem was or why this fix fixes it - I dug a little further and found your video which not only satisfied my curiosity but also served as a friendly companion while I played along at home. Thank you!
footnote: my setup video of the DS415+ has been my most popular upload so far with 22k views! th-cam.com/video/-qSHR32jNQc/w-d-xo.html
Don't buy a power supply, bodge one up!
Get the plug, and a female atx connector then wire those together.
seconded or thirded! i mean, i had a laptop for a good 8 years that literally had a jack from another laptop hanging out of the kensington lock port via a red and a black wire powering a IBM thinkpad from a dell/hp charger
Maybe a year ago I did a similar "repair" on my and my friend's DS415+. Friend's unit was in a similar state shown in the video (blinking power led and solid orange disk leds) and it was resurrected. My unit was fine because of a lot lower use time, but I just future proofed it. Still, it sits in back of my head that this will happen again, so I don't run my unit 24/7. My friend just shelved his unit deeming it not reliable and switched to QNAP, which also failed after around 18 months (different reasons of course).
Yep, I've got a Cisco ASA 5506 firewall that was on that list too, but it hasn't failed yet. Although I'm pretty sure the failure mode is on reboot (like you said, LPC clock is mostly just used for the BIOS boot ROM), so the fact that I'm running it on UPS and it's almost never rebooted may be why I haven't seen it fail. For all I know, the LPC clock is dead as a dodo, and this thing is one reboot away from following suit. It's fixed on newer revisions, so I'm curious whether they've just done a resistor bodge, or if they've re-spun the boards. Cisco does offer proactive/post-failure RMA for in warranty units, but their field notice suggests failures begin after 18 months, so they that's conveniently out of the statutory warranty period if you're not paying attention. Thankfully Cisco can sell you a service contract which would also allow RMA.
I don't know if Dave has re-stocked, but there was a time, when he made this video, at least, that there was one common electronic item that I had that Dave didn't! LOL
i bet he runs out of 555s from time to time too
the reason you may have thought it had not been setup before is because the synology os actually creates a partition and runs on the hard drive(s) so in your example if you swap that single hdd with a fresh one you would have to setup dsm again. The synology in a diskless state only has small on board storage. Keep this in mind if you want to swap 4 new larger drives or 3 new and a ssd cache. Depending on your raid config you can add 3 new drives and once they have initialized and join the pool you can swap out your original first drive without losing your data and config. But in your situation it doesn’t matter because it’s a new setup anyways.
I have a ds1815+ and it has the 100ohm c20xx fix installed from the factory. The next common bug with the 2015 synology nas's is that when powered down they will not power back up. One fix to that is to solder a 1000ohm resister between pads at the Q4 transistor. That unfortunately did not fix my nas. By the way Synology, knowing these nas's were defective, happily replaced mine every time it failed (four times in total) until the warranty of course expired. Then they tell you can can save your data (60TB in my case) by buying a new $1000 DS1821+!!!
I searched and searched for a solution to the no startup problem and came across a suggestion to simply short the connection between a green and black wire in the 24 pin connector (the 3rd and fourth pins from the right side) and the nas would boot. When I did this my nas powered on, to my surprise. I did not like the idea of power off though by simply yanking the power cord, so I installed a switch. To power on you just close the switch and to power off you do a normal shutdown from the menu and when all the drive lights go out you just open the switch.
It scrubbed all the drives and has been working ever since and I saved blowing $1000 on a ds1821+!
Here is a picture of the fix... imgur.com/a/TdHTAE8
I'm sure you're right about the P-FET failure. It's probably in a hot spot on the chip or something equally mundane. The series resistors adds a little extra inductance that might affect the clock shape some, but 25 MHz and no obvious overshoot minimizes my concern about that. A stiff pull-up will stress the N-FET complement some, but I would use it for non-essentials. What are the chances that the drives can be read in another NAS if this one failed?
You can put the drives into the latest equivalent box and it will migrate seamlessly.
I've just had the same issue, and was able to fix it thanks to you.
I could also not find a 100 Ohm resistor, so two 51 Ohms had to do.
Thanks again!
Fixed my personal DS415+ about 18 months ago, and luckily it is still running 24/7 today. I also happen work in networking and had to replace a bunch of Cisco routers and firewalls that were affected by this bug. Thanks for the video!
How's that DS415+ holding up? I'm about to do this fix and want to know the potential life I can expect (got the DS with 4 x 4TB drives for $700 so not the worst but I just finished moving all my data and after the unit crash I did a power cycle and then she died)
@@ovenfood After 3 and a half years since it’s surgery, it is still going strong. Good luck with yours!
@@dangoswick 100R 0.5W resister was added and bing bam boom shes back to her former glory.
@@ovenfood That’s great news! It’s a great little NAS.
I recognised this problem from the thumbnail! I had this problem with my DS1515+. I think it’s the LPC bus that physically degrades so it stops booting the BIOS (if it’s hosted on the LPC bus). Synology didn’t disseminate any information regarding the issue despite my registering the device. I even tried claiming a repair on the warranty, but was told there was nothing they could do. They acted like the problem didn’t exist. Maybe I was just too new to the party.
The resistor has fixed it for me (after mine stopped working) and it’s still working about 3..4 years on.
Very disappointed with how Synology and Intel handled this one considering a NAS is meant to be rock solid and reliable.
Thank you so much, I applied this fix and it saved my DS415+.
Thanks for the video! The resistor (and battery) fix worked! Super stoked
The upshot is the push pull clock driver fails to push or source , but can still sync... hence the low impedance pull up.
Just did the surgery on my DS723+ and it worked! Thanks!
@9:50: i suppose there is an bootloader on flash memory with some compressed data.
When you put some hdd, bootloader can extract all data on hdd, so you'll have an fully operational nas.
It happened to me on both nas i have.
It just has enough to get you to the install screen. It downloads a file called a .PAT file that has the main OS, and that extracts to every drive.
The year is in the synologys modelnumbers.
Like DS4(the number off drives)15(the year, and no it´s not 1915 :P ).
Pretty handy when looking around ebay and the likes for older/ceaper hardware.
The first digit (or the first two, in some cases) is actually the maximum number of drives the device can manage, including one or two expansion cases of 5 drives each, if ghe DS has ports for them. Which explains numbers like 7, 15 or 18.
I have a first gen Drobo that still running with four Seagate ES.3 type drives installed. I've owned it since 2007. I've another one I got in 2014. It is also running perfectly.
True. My Drobo gen1 is also still running.
Two days ago e "repaired" Synology RS2416RP+ Rack mounted 12 drive unit just the same way
Undergoing copy of the 24Tb of data right at this moment :)
So, in case anyone needs this, It does affect bigger models also, and the solutions is the same.
(The pads are on a different part of the board, but you cant miss it, they look the same)
ok great,
I think synology also had these atom C2xxxx series inside there 19" rackstations and there fore they are also affected by this hw bug.. ?
so perhaps than this resistor fix will also work the same way for the DS1515+ DS1815+ and some other models perhaps.. ?
Im still wondering then if this transistor fix is permantent, or only slowing it down and still make the atom chip to work.. ?
@@floorinterfacing1582 The RS2416RP+ has an Intel Atom C2538 and i can attest that it has the same problem with the same "solution". As for the DS1515+ DS1815+, i really don't know. I'm however not using the storage in production anymore, even thought its for data that is "better to have and not need than need and not have".
I'm changing the sucker.
@@maxsnts Did you do this "solution" on the J2 section by the main 24pin power connector?
@@BradleyLemon Yes yes a 100ohm resistor between pin 1 and 6 of J2 Connector
Heck, a free $15 2GB DRAM is worth opening it up :-)

@@frogz why not?
That porch reminds me of tristate logic. The porch is around when the chip select would be driven in some circuits, it's been quite a while since I looked at it.
Intel has come a gutser so much in recent years, the SpectreNG & LasyFPU vulns were fun with fixes that broke more things. That one made some fun days at work.
Can I apply this resistor fix before my unit fails?
Of course.
@Chippy Chen thanks, soldering the resistor as we speak!
@EEVblog I'd just power it from a laptop power supply + dc-dc ebay converter or one of the 200 ATX power supplies that you have floating around. Drive wise, I'd look at shucking external 3,5" WD Drives, since they contain white labeled WD Reds.
Not guaranteed they come with white labeled red's, some are just white green's or blue's either. You can't know upfront and wd won't tell you because they don't want to be stuck to using only a single type for their external enclosures. As far as I heard though the mybook duo's come with obvious red's in it (same model number as retail, the above mentioned mostly have slightly different numbers which may indicated a slightly different firmware), maybe just because those are two in a single enclosure and wd wanted to make sure they work without issue
AFAIK, the NAS saves settings to the HDDs so if you are setting up using all-new drives, the first-time configuration process starts over.
Not sure about Synology, but my old D-Link NAS was installing whole operating system on a hard drive on first boot.
@@djunia4u Yup, the Synology NAS do the same. They have a basic built-in boot environment that gets you through the OS install process, then boots off the HDDs.
I am going through this now with a Synology DS1515+ with the Atom C2538, It started with the Synology randomly rebooting only between 4am-7am (never in the day) and then it dies. Going through warranty replacement at the moment. I also have an RS2416+ which I am quite reliant on with the same CPU, hopefully, I do not get that issue with this one.
A little update on this, Synology sent me a brand new unit today. Has the same CPU but it is a brand new unit, so I guess it already has something done to it to rectify the issue.
You are always so happy. Nice to look at.
I saved one of these exact units from the dumpster when I was charged with building a new office for my small firm! I quickly sequestered it into my "cool crap to work into the home lab" pile. This was along with two T130 servers. Haven't decided what to do with them yet. Excited to watch this video...
Daves dumpster is amazing...
plot twist: Dave is a serial thief and the dumpster is the shop.
thank you so much, I repaired my synology ds415+ today ,it has the same fault and adding the 100 ohm resistor fixed it
Thank you! I have an Atom based 4bay Netgear Readynas sitting broken in a similar way, waiting for some time when I get a clue what might be wrong. I will take a look if I can find a similar solution for the Readynas.
Nope, my unit uses a different CPU (older Atom D410) and I can't find similar solutions to Readynas. And the thing seems to have an dedicated oscillator. And it uses a non-standard PCI-like connector to the backplane, so I can't even reuse it in my PC :-(
I love the tech verb..."buggers off" 😂
that comment of "focus you b_ _ _ _ _d" was hillarious
Reminds me of AvE's "Focus you FUCK... thank you"
AvE says Focur you fack, that is how he pronounces it too.
Dear @EEVblog, I am going to disassemble my NAS, to put it into a 10inch case and wanted to ask you if you think it is possible to use a pci extender for the harddrive pcb?
Hey Dave! I actually work tech support for Synology! HMU if you need any advice/help setting up, or utilizing, the NAS/ DSM. Happy to help!
......you poor poor man, i feel synpathy for you, this can not be a easy job, it isnt just old grandmas that are like HELPPPPPPPPPP MY SERVER IS DOWN

Hello
I bought 10 resistors for 2.81€ on ebay and solder one to the board like you did and tada, NAS is back online. My boss will be glad to know that !
Thank you for sharing :)
I thought those caps vented out the bottom from the plastic?
I added the 100 ohm resistor yesterday, but now slot 1 on my DS415+ is gone. Any suggestions?
I'm not an electronics guy, but I know how to do a little soldering. I bought the 100Ohm 1/4w resister and I'm just wondering, does it matter what direction you place it when you solder it in, like a one way door, or does it not matter like a two way door? Any help would be appreciated.
I figured it out since no one answered, I'll post the answer for a future person trying to do this. Generally speaking, no, the direction of the resister doesn't matter. It more or less depends on the circuits around it. However, since I didn't know the circuits around it and if that was relevant, I did find a video using a single 100Ohm 1/4w resister instead of the two like in this video and the side of the resister with more striping goes toward the pin 1 position. Anyway, I soldered it in place, replaced the battery and viola, my DS415+ is back up and running and will now serve as a backup to the new DS920+ I bought to replace it. This video was helpful though, and this fix did work.
Youpie! I found DS415+ in the "for secure liquidation" bin on my employer two days ago.
Sure enough, once powered, it was flashing blue led and keeping all disk indicator leds lit.
Today, I have installed the resistor as instructed, and to my surprise (and great pleasure), the device booted up correctly. In the meantime I reset the settings to defaults so it is now detected by SL assistant tool in my network! Seems to work fine! Thanks for the great piece of info.
"No Fix" just means no silicon fix. Most of those things are fixed via firmware.
I got a replacement 415+ from synology when mine died because of this issue. It has the same 100 ohm fix. Running strong since Jan 2018.

Is the atom Z2760 also affected? Just happen to revive a samsung ativ xe500t1c.
Shouldn't be, no.
@@SianaGearz Great! thanks!
My 415+ "died" a couple of months ago, of course just a year out of warranty. I had no bloody idea the Atoms in these had this problem. Luckily I came across this resistor fix on the Synology forums and it booted right up again! Wish I had known this sooner so I could preemptively apply the resistor to slow down the degradation. I wonder how many years the resistor added.
We had a bunch of Cisco routers and Meraki firewalls affected by this, a few died but we replaced most of them proactively... What a pita.
Could you use a schmitt trigger to sort out that clock signal?
The flash board actually looks like an eUSB, which is used in a lot of products, it's very convenient.
The storage connectors are actually SAS connectors and not SATA, does synology DS support SAS drives?
I was effected by this C2000 bug too. It was one of my server boards. It runs for month and after getting it off for service it not came up again.
The manufacturer just repaired it with a simple RMA process, especially created for the C2000 bug.
It was really a big thing in industry these days. It effected a lot of systems: Network switches, routers, storages, low-power servers, and so on...
Synology and dumpsters are synonymous with one another. I inherited several at my current employer and all have failed spectacularly in various ways.
Any chance there's a variant of this fix for the DS1511+ ? it's a completely different board, but I do see a 12 pin on the board that MIGHT just be the same thing.
Cant thank you enough... my DS415+ died on my a few months back , I bought a more recent one and kept this one it its box, I wanted to sell it for parts and then I just googled a few things and found your video... followed it to open the box, went to buy a 100ohm resistor, installed it and... ITS ALIIVE !!
I cant believe that Synology actually told me it was dead, they must know of this fix !!
I have a QNap TS-451 that has developed faults which I think are also related to the CPU issue. Any known DIY fixes for it?
I got my DS415+ in January 2015 had the issue and got it replaced in January 2016, has been running fine ever since.
I had a PfSense router that suddenly failed. Likely the same issue. I wonder if it would be possible to locate a place to add a pull-up on that board?
Does Synology work without the Klowd? After a Seagate backup drive that wanted you to create an account, I'm trigger-shy about buying these backup devices.
My DS415+ died of this bug too.
I got a replacment unit from Synology (like 2 months after RMAing). I could not wait this long because I had to access my data and thus bought a DS918+ as replacement unit. So I got a spare "unused" DS415+ sitting around...
Where do you buy the 100 ohm resistor? I have looked and don't know which one to buy. Thanks for any help.
Do you think the PCI slot is actually PCI or just them using the connector? It would make sense it was a PCI - SATA board.
When the 2000 bug strikes it's time to join the resistance.. ;)
I have installed this fix on multiple Synology boxes. Just last week I fixed a friends 2415+ and so far they all work.
Wow, dude, you might have just saved my bacon. I have a 1515+ which uses the same CPU, and is quite an early batch so it probably has this problem, but it's far out of warranty. I think I'll pre-emptively apply this fix! I like these devices. I can see why people say they are over-priced, in a sense they are, but if you just want something and you want it to work with no fuzz, these are great. Well, except when they have buggy Intel silicon I suppose... But other than that ;) Mine is 6 years old and going strong otherwise, running 24/7 most of that time. Here's hoping a 100ohm resistor can add some more years.
Also, you asked in the video - getting the install prompt does not mean the NAS was never used - the way these boxes work is they actually install and run their OS from the users harddrives. So, since the drive was unrecognized or blank, it had to install OS from scratch from ROM and set up anew.
Can you do it preemptively?
@@z352kdaf8324 Sure, I don't see why not. The fix doesn't actually "repair" anything, it simply prevents the failed hardware from blocking the system boot process. The failed hardware in question isn't used in the NAS and thus the failure doesn't matter in and of itself.
Hello, my synology rs2416 is not booting after dsm update. The blue and orange lights are on. I think I'm having the same problem. How long does putting 100 ohm resistor to the solution solve the problem?
On first glance that unpopulated connector you used for the mod looks kinda like a TPM header. That also has the LPC bus wired up to it, and could possibly be something this motherboard might like to have in a different design variant.
I've got a Supermicro NAS with a C2758 in it - stopped booting one day, got an RMA for it and Supermicro started talking about a $150-300 fee. Sent it back and Supermicro went very quiet - then it came back from Taiwan via express freight - all working, with an (as of then) unreleased BIOS update. The note said "EC update" and no payment was required...
5:02 that's...an odd place to have a warranty void if removed sticker.

Maybe it's referring to the whole memory stick, if you upgrade it or whatever tge warranty is voided
@@resneptacle That's the thing. Those stickers are usually placed so that you'd have to tear them in order to get whatever out, thus proving that you did.

Nothing happens to that sticker when you remove the stick. Weird.
It's a SODIMM RAM module. I upgraded it in my DS416play the other week. The sticker is still on it, they couldn't be the wiser if I put it back. Though the void period is long gone now, so it is moot for me.
@@Okurka. Stop propagating that myth. The warranty WILL be voided if the company wants the warranty voided. Period. Laws don't matter, you don't matter. The only way to get a company to fix/replace the item you've been into its to take them to court. (Or possibly have an attorney send a letter to them, which will cost $100-200. So not usually worth it.) You calling them for warranty work and sawing, "Hey... You... The law says..." It's an absolute dead end. They can do whatever they want, because they know you aren't going to be able to do anything about it. I don't like it, and it's b.s., but that's the way it is.
@@pelic9608 that's what's so infuriatingly curious about it - if they had wanted to stop you upgrading the ram, they could have taped it down with the sticker, so you can't remove the ram without breaking the sticker.
Maybe some reverse psychology to catch eternally curious people like me XD
I would trust it enough if you can pull out the hard drives and connect them to a new nas and recover the data.
I think it isnt more likely to kill your hdds than any other nas, most likely it would just stop booting someday.

Restoration takes few hours up to 24 hours, thus costs are very very low and delay is good for a safety backup.

Well opamp outputs have a pull up and pull down transistors on their output. If the pull up transistor or it's drive circuity fails than the signal will not rise much over the low level voltage...
At this point hardware manufacturers looking for a free design review for the next iteration would do well to drop the prototypes in Dave's dumpster room (if they aren't doing that already).
I don't know about the fix. But I have a Synology DS412+ with 4 1TB WD red drives and only had one problem due to not doing the OS updates. I got that fixed by just removing all the drives, putting in a temp drive to get it booting. Then updated the DSM software. Then putting the original drives back in and then DSM updating the copies on the drives. Didn't lose any data and It is still running today. Also If encription is not enabled you can pull the drives and connect them to a linux computer or run a live flash drive that has mdadm and access the drives.
How to read Synology models for NAS units
DS = Diskstation (desktop model)
RS = Rackstation (server rack mount)
DX = Desktop Expansion unit (Connects to compatible units through ESATA cable, drives can be raided or JBOD in expansion but not mixed to raids in DS unit. So a raid can't use drives in both like 2 drives in DS and 2 drives in RX for Raid5. Can only Raid5 in just the drives in DS or DX for two pools.
RX = Rackmount Expansion unit. (connectors allow rack expansion unit to be seen as part of RS unit to allow drives across both units to be raided together. )
RP after model number = Rackmount with replaceable power supplies. Example RX818RP+ has 2 removable power supplies, while RX818+ just has one built in unit
1st number = number of bays * DS415+ four bay = 4 DS218 two bay = 2 DS718+ two bay but can attach expansion unit =7 *
second 2 numbers is the model year DS415+ means it's from 2015 but may have been sold till the next model like DS417 is release.
Slim = smaller units that take laptop/ ssd 2.5 inch drives only. DS419Slim
Play = includes faster CPU and/or more memory for transcoding video
+ = faster model compared to another model of same name being sold
J = lower cost model of another model of same name. Example you can have 3 models name DS218, DS218+, And DS218j but different specs.
There are more but those are Enterprise rackmount storage units.
will this fix perhaps also work for other synology models like for example the DS1515+ and DS1815+ ??
The explanation for this find might be rather simple. Synology refuses to provide parts or any repairs to the units, once they come out of the warranty. Refuses, as in - you cannot pay money to get any authorized repair. So, once the warranty runs out, boom, they will direct you to just go out and buy another unit. If they feel gracious, they might throw you a bone and give you some tiny discount.
