@@hddrecoveryservices I need help with this SAS Hitachi ultrastar hard drive. It beeps once when plugged in, but doesn't spin. I'm not sure if this is a diode with the s marking code. Here is a pic link... th-cam.com/video/jH0GtQeJQhA/w-d-xo.html
Man you just saved my ass!! Thanks so much for doing this exact video, the pcb board was exactly what the problem and I got it fixed and saved a heap of cash because of your help. THANKYOU 🙏🏻
Thanks man! It’s worked after removing one of the diode short circuit beeping was gone and successfully recovered our old data! ❤! All positivity to you
Hi, I liked your video. However I am left with the question, how can the circuit work without the diode? I am scared to apply power to the board without the diode as there is a chance it can fry the board. Can you please explain the role of the diode in this instance and how the board can work without it? Thanks.
Hello guy, I have a Seagate 4To who doesn't spin. I tried to remove the diode like you did but the disk still not spinning (I mesured 0.693 with multimeter). If I replace the entire PCB do you think it could works ? Thanks for your answer !
This video helped me to diagnose and get a damaged 1TB Seagate video hard drive (ST1000vm002) from a Rogers Nextbox 3 going again. The problem is exactly the same, a shorted diode (which did not test ok after removal). When I removed the diode the drive spun up and was recognized. I am surprised the drive board without that diode enables the drive to work. Can the drive be operated "as is" or should the diode be replaced?
after removing diodes and having the drive power up would you advise against re-using the drive or would you allow clients to continue using the drive as is? or is best practice to backup the data and get a new drive?
Thank you so much. I removed the bad diode now hard drive spins! I am able to get data backed up. Can a diode be purchased and soldered in? Or the diode crapped because of some other issue?
I've got an old SCSI Seagate Barracuda ST150176LC that won't spin up. No noise at all. Drive light on the circuit board does blink, but otherwise no activity. I located two diodes, both Motorola 933 1BL3 ZP, that appear shorted. I haven't removed them yet. Do they need to be replaced? If so, what equivalent diode can be used? I haven't found specs for these diodes. Thanks.
ST3000DM001 Have problems with Head 4... When imaging the drive I can see a pattern: where a batch of sectors wouldn't get read, then a long batch would get read, and then a small batch not read again etc - with equal intervals. I ran /7 -> X through serial and got resistance values for all heads. All heads reading around 300 (need to convert from HEX to Decimal) except head 04 (head 5) which reads 540. Unfortunately I do not have access to hardware recovery tools like PC-3000, MRT etc... I've disable re-trying reading in firmware through terminal and can now quickly image the drive with HDDSuperClone without getting stuck at dead head for too long. But have a cleanroom, so will attempt a head swap after 5 healthy platters get imaged. If headswap will not fix the problem - time to send to specialists with hardware recovery tools.
Man i just go two of these 3tb seagates from a lady in town. Both are plugged into the SATA 6 pin power port on my EVGA and on only recognizes 3.8 gigs and the other does register at all. One makes that beeping noise as well while the other spools just fine but cannot initialize the drive due to an I/O error. .
Great video! Do you mind sharing what tools do you use to remove the diode? I have a same exact drive ( actually 3 of them! ) and they all died on me at the same time!
I have 3 dead diodes 2 x 1ROZ and a small S41 on a seagate 4TB external drive that does not start up. the outside diode has power. I am a bit nervous about 3 removing them.
hi, I in similar case , I replaced diode and fuse , still without work .Can you tell me plz what is 6402 u3 chip think is broken too .Getting from Cuba
Any idea about a repetitive humming noise coming from the drive and the platters don't seem to be spinning. Windows on detect 4GB... it's a 500 GB drive. Windows want's to format the 4GB (I didn't). FTK Imager won't mount the drive either. Drive failed during a power outage... suspecting a power surge. Checking what look like the diodes didn't find any shorts...
Very interesting. Impressed with your knowledge and very professional. Shame we don't have people in the UK like yourself. Not only a very nice guy and knows what he's talking about but also whiling to share his experiences and knowledge here on TH-cam. You sir have a new sub. An see myself going through your entire channel watching a lot. I've had a few experiences with bad drives and loosing data so will be interesting to watch your videos. I have a USB stick that says it read/write protected when it's not and has never been made protected. Just on day it decided to screw up and I lost so much. It's was only 8GB but I had 7 years of Xbox360 game save files and a backup of some important stuff. One question I'd like to ask. Without going into huge detail I have a custom water cooler very high preformance PC and I've seen some people have a clear top, see through lid or case cover on there HDD so you can see it all working etc. all my SSDs are on show and I'd love to do the same
I see what you mean, I've seen those covers. Custom made out of plexy. At my old work we actually made one :). But once hard drive is opened it would be hard to keep it reliable, unless you run RAID1 in case it fails.
Digital777 Studios I didn't learn any of this in school. Lots of trial and error and persistence. With data recovery you need to master PC3000 the rest will come naturally
This is somewhat HardDrive related but not exactly. I have a Buffalo Link Station Model LS210D0201 which I need to replace the drive, but I can not figure out how to open the case. I have searched on the Internet and I can not find any disassembly instructions for this model or anything similar. I don't want to break the case since it's functional. Just want to open it to replace the drive. Any suggestions?
i have the same issue but both diodes seem to have continuity. one reads .699 and one reads about .500. is it still possible one of the diodes is bad? should i remove them and test the drive without them?
Goodday, I've an 2.5inch bare drive as usb stick in my tv. After my son has dropped it really hard it ticks while playing movies. Did it died? it is freshly filled after format so no gaps from fragmentation
Hey i just sent a drive to outsource datarecovery services, and i KNOW for a fact the data on it is still good. The problem it has is that it TRIES to spin up but cant complete it. So i logically figured its either gonna be the PCB or barely possible the Spindle having a problem. I was told 3 times that all it would need is the $60 pcb swap, then they call and say "nope only data recovery will work" But literally 30 mins before it just stopped spinning i WAS AT THE DAMN DESKTOP, the files are fine. And you seem like an upfront sorta dude, how much would it cost for a PCB swap, or in the worst case a Spindle swap, i really really dont have a lot of money, which is why when he quoted me $600 dollars for data recovery, i just thought "data recovery?? why it doesn't need data recovery, the problem is its not spinning up"
I have the same Seagate HDD which was dropped from around 2ft a few days ago. Since then it will not work. I can hear that the disc is not spinning but there is also a beeping noise. Did your HDD also emit a beeping sound when plugged in? I'm just trying to determine if i have a PCB issue or internal issue(such as stiction/head damage/spindle problem etc) thanks
Thanks alot for your efforts I have 2 TB seagate barrcoda Stops working I have another good one , same spec When i use the board of the good one with the hard it give me error No sound , no clicks while spinning And they said to me you have to use the same board Is their any chance to fix it Realy i appreiate your time Thank you
Im sure this is a stupid question but I don't get something. You touch red and black probes together to demonstrate the sound. Isnt this exactly the same situation when the current goes through the diode? In other words if the current goes through the diode and we touch the red and black probes on both ends of the diode it should be exectly the same as if we just touch them together (without the diode in between) and the sound should occur?
Not stupid, he was not clear about this: The basic function of a diode is to let current flow ONE way only....by "shorted" he means the diode lets current through both ways. The "arrow and a line" he mentioned is the symbol for a diode (can't type it here, just look it up and you'll see what I mean)...the arrow part of the symbol indicates which side is + and the "line" side of the symbol is the minus (negative) side. Current is supposed to flow from plus to minus, and if you test with the probes that way, you are supposed to get a sound...but if you switch the probes (put red on the minus side, and black on the plus side) and you still get a sound, the diode is no good.
So i plugged in a wrong drive and the diode broke, all i want from it is a couple gigs do you think its a bad idea to knock of the diode and to open it in windows? or replace the diode?
Hello! It is necessary to repair the hard drive PCB, with this card drive will not start. Where to start repair, what do you say? What I did. Checked suppressor - they are good, I changed the charge on obviously working and then the disc spins. What do more? Thank you in advance.
I noticed that you have done a few of these videos (which are great) but they all turn out to be bad diodes. What about if the diodes are fine? I have a Seagate 500GB that makes no sound but the diodes appear to be ok. What should I be checking next?
My 1tb external dirve spins but led not glowing and it is recognised by computer but not showing up in my computer or in disk management ? Please tell what to do. ?
I have a ST2000DM001 that doesn't spin. I've cleaned the contacts with a eraser. I've also checked the diodes. They are both not shorted. Is there anything else I could try?
@@hddrecoveryservices Thanks for your reply. There seems to be no fuse on the PCB. As the HDD doesn't make any sounds at all, the issue is probably the PCB right? If I would replace the PCB for a new one, I would need to replace the BIOS chip on the new PCB for the 'old' BIOS chip, right?
Hi, I have this problem with a Seagate ST2000DM001 - I got the same short on one of the two Diodes. I removed the diode which had shorted, but it still indicates a short across the pads once removed - and the drive still will not spin. HELP!!
Paul Archer Paul at this point your best bet would be to locate an identical PCB part number and swap out the eeprom chip from your failed board to a new working one. That will adapt the new board to work with your hard drive. I don't go beyond troubleshooting the diodes on these when it comes to failed/shorted boards because my inventory of donors is really good and it is just way easier to pull the donor than try to figure out what is wrong on component level.
I took my external drive out of its casing and there is obvious burned marks on the sata bridge and not sure of the pcb. What would it cost to repair this or is recovery needed? Please let me know thank you.
I have the Seagate 3TB (ST3000DM001) and it spins up with no strange noises, but will not be detected, even with Disk Utility...what should the next step of diagnosis be? Edit: The drive spins up normally, but then stops spinning after just a few minutes. I already cleaned the contacts on the board (which were dirrrrty!!) but that didn't help :(
Hi please reply My usb power bridge on 2tb hdd is not picking the hard drive. I checked it separately the bridge led is on when connect to power but when connect with hard drive the light goes away and no sound nothing on hdd. Please suggest
hi i have the 1tb baracuda it power up and spins with no funny noises , shows up as being pluged in with usb but doesnt show up as a usable drive if i go to drive manger it doesnt show up , im thinking its the pcb on it any ideas?
Thanks for your videos! Any idea what might be wrong if seagate 2TB works just fine when detected, but... it's not detected all that often lately?.. It spins just fine, no weird noises. No errors in any test, SMART is ok, disk isn't too old yet (the newest I have aside from its replacement). And somehow BIOS just says says it's not there after being stuck on motherboard loading screen for like 30 sec. Swapping to other SATA doesn't help, other hdds work fine in its place. Tried to clear its contacts like you showed in this video, doesn't seem to help (but I got it detected at least 2 times after that). There's no data to save left, just wondering if it's something that might save me 2TB of space being tossed to trash.
Hi I have a hardisk with the Rom (Bios burned - in the sense that PCB's rom is missing) Reason I had buying a card to do the swapping but the repairman lost the original card) Do you think it is possible to recover my Seagate Hardisk? In short, the HD has never been opened and card that has does not have the original BIOS I feel the engine turns but it doesn't see any data windows with new pcb donnor Thx Franco Italy
Hi, I received a NTLDR error. My 500 gb Seagate Barracuda divided in two partitions is not detected in Bios bootable section. It makes a slight beep sound whenever I start my PC. Just two beeps. What should I do?
I know this is an old video,but I have this drive it died a year ago and I just got it up and running and Windows and Linux don't even recognize the partitions?
Got a quick question... I am a sad owner of seagate expansion desktop 100664987 rev b - 3TB version. Lately without any sign drive just stopped working. Right now situation is: when connecting drive the computer I can hear that it starts spinning but after two-three seconds it just stops and nothing happens. Do you thing that this might be something with device pcb or power supply pcb? I know that this is only estimation and guessing without seeing device but I would like to know your opinion. I can upload video showing how it behaves if that helps... Alternatively, what would be estimated cost of recovering data from that drive?
When i clean the board and connections,diodes and caps are not shorted.The drive are not recognized i n Bios,sometimes cause to freeze on start.What may be wrong ?,help.
Scrub a copper penny with a pencil eraser, then look at the tarnish a week or month later. Also touching the cleaned contact with oily fingers will cause contact problems later. Maybe good for return repair later, easy scrub head preamp contacts again to fix until next return..
does replace pcb / board also fix slow reading hard drive? I have WD home studio hard drive which suddenly very slow reading and some files cannot be read, thanks in advanced
then u have anonther component that short out...find this!..i u remove the diode, check if the still shots out or if the diode could be ok! i have the same drive with the same problem but my doesnt spin on...i removed the bad component but still not spin
Hi.. I need help ASAP please.. my hard drive does spinn and i feel the motion of the inner parts even though its not detected by either bios or pc or any other pc.. what to do???? is it PCB board or head problem or what..
I have a Seagate where it no longer recognizes the HDD password, bedsides a platter swap at technical lab can switching the exact PCB get it working to get the data off??
yo, I received a factory new drive from Seagate and the motor doesn't spin up. It gets detected in the device manager, sometimes also in the disk management without any storage showing up for it. I actually ordered two units, both of them seem to be from the same charge, although the PCB of the defective drive looks a bit discolored. I tried that one first in my external drive enclosure and it didn't spin up, so I assumed my external enclosure was defective (many reported cases of not detecting drives with more than 2TB of storage). I dropped the other drive in there and it worked without an issue, so I guess my one of the new HDDs is simply defective. Do you have any thoughts on that?
so i checked my drive and i have a short circuit, so if i take off the diod i can than make a copy and than ditch the old drive how should i do it?? what programms should i use?
I have this drive and it died! spins up fine - sounds normal - windows and bios do not see it - i removed the pcb and cleaned the contacts - same problem - any idea what could be wrong?
i have replaced bios from one pcb to another pcb. Source pcb is kc48 and toner pcb is kc66. after changing bios the hdd detect but after few sec disconnecting .... what is the problem?. how i solve this issue?.
I have this exact drive and the exact diode tested bad, I removed the diode and the path tested good. The other diode/path tested good. The drive still does not spin up. What would you recommend the next steps be? I don't have a lot of internal experience on HDD Recovery, but I work with computer and am pretty comfortable around most things computer related. Any advice or assistance would be appreciated. Another note, I only have one of these drives, so I cannot currently take out parts from one and put in another. If that is a viable option, let me know and I'll look at picking another drive up. Thank you in advance.
HDD Recovery Services is another short an easier fix then another option? The stuff that you do is very inspirational and I would like to get more in to this line of work. Great content and video production.
Would really appreciate an answer to this. You use special software after to look at the sectors etc, is this necessary or could you just plug it in and use as normal?

What if it does spin but isn't recognized?
Thanks so much! I accidentally broke the connector to the diode, but my drive spun up enough to get the data off it. LIFE SAVER!

Are the reading heads any different on the same model of drive between SATA and ide, thank you for your videos and any help you can give
sometimes they would be interchangeable as long as they match up on specs. Different vendors have different criteria for parts matching
So where do the probes for the multimeter go? One on each diode or one on each side of each diode?
you need to test the diode. Negative probe goes on the cathode side of the diode, and the positive probe goes on the anode.

@@hddrecoveryservices Thanks for your reply. There seems to be no fuse on the PCB.
As the HDD doesn't make any sounds at all, the issue is probably the PCB right?
If I would replace the PCB for a new one, I would need to replace the BIOS chip on the new PCB for the 'old' BIOS chip, right?
Yes, the ROM needs to be moved
@@hddrecoveryservices Allright, thanks for your help!
man i love your videos....
thanks!
My hard drive only spins slowly and gets very very hot is tehre a fix to this?
Hi, I have this problem with a Seagate ST2000DM001 - I got the same short on one of the two Diodes. I removed the diode which had shorted, but it still indicates a short across the pads once removed - and the drive still will not spin. HELP!!
Paul Archer Paul at this point your best bet would be to locate an identical PCB part number and swap out the eeprom chip from your failed board to a new working one. That will adapt the new board to work with your hard drive. I don't go beyond troubleshooting the diodes on these when it comes to failed/shorted boards because my inventory of donors is really good and it is just way easier to pull the donor than try to figure out what is wrong on component level.
I took my external drive out of its casing and there is obvious burned marks on the sata bridge and not sure of the pcb. What would it cost to repair this or is recovery needed? Please let me know thank you.
you might want to check your drive in another enclosure first.
I have the Seagate 3TB (ST3000DM001) and it spins up with no strange noises, but will not be detected, even with Disk Utility...what should the next step of diagnosis be? Edit: The drive spins up normally, but then stops spinning after just a few minutes. I already cleaned the contacts on the board (which were dirrrrty!!) but that didn't help :(
Hi please reply
My usb power bridge on 2tb hdd is not picking the hard drive. I checked it separately the bridge led is on when connect to power but when connect with hard drive the light goes away and no sound nothing on hdd. Please suggest
Did you not have to replace the failed diode...
Not if you just want to save the data and don't care about the long term protection of the hard drive
hi i have the 1tb baracuda it power up and spins with no funny noises , shows up as being pluged in with usb but doesnt show up as a usable drive if i go to drive manger it doesnt show up , im thinking its the pcb on it any ideas?
Please could you help me what to do, one of harddisk partition has file system courpted i traied many ways pleas help me 😢
Thanks for your videos! Any idea what might be wrong if seagate 2TB works just fine when detected, but... it's not detected all that often lately?.. It spins just fine, no weird noises. No errors in any test, SMART is ok, disk isn't too old yet (the newest I have aside from its replacement). And somehow BIOS just says says it's not there after being stuck on motherboard loading screen for like 30 sec. Swapping to other SATA doesn't help, other hdds work fine in its place. Tried to clear its contacts like you showed in this video, doesn't seem to help (but I got it detected at least 2 times after that). There's no data to save left, just wondering if it's something that might save me 2TB of space being tossed to trash.
Hi I have a hardisk with the Rom (Bios burned - in the sense that PCB's rom is missing)
Reason I had buying a card to do the swapping but the repairman lost the original card)
Do you think it is possible to recover my Seagate Hardisk?
In short, the HD has never been opened and card that has does not have the original BIOS
I feel the engine turns but it doesn't see any data windows with new pcb donnor
Thx Franco Italy
Hi, I received a NTLDR error. My 500 gb Seagate Barracuda divided in two partitions is not detected in Bios bootable section.
It makes a slight beep sound whenever I start my PC. Just two beeps. What should I do?
I know this is an old video,but I have this drive it died a year ago and I just got it up and running and Windows and Linux don't even recognize the partitions?
So the hdd will turn on without replacing the shorted diode?
Technically yes
ive removed the diodes, but the short circuit beep is there, any ideas?
Got a quick question...
I am a sad owner of seagate expansion desktop 100664987 rev b - 3TB version.
Lately without any sign drive just stopped working. Right now situation is: when connecting drive the computer I can hear that it starts spinning but after two-three seconds it just stops and nothing happens.
Do you thing that this might be something with device pcb or power supply pcb?
I know that this is only estimation and guessing without seeing device but I would like to know your opinion. I can upload video showing how it behaves if that helps...
Alternatively, what would be estimated cost of recovering data from that drive?
My tvs diode is not shorted and the disk does not spin. What do I test now? Should I renove it anyway?
You need to check 0ohm resistors by power connectors make sure those fuses are not blown
When i clean the board and connections,diodes and caps are not shorted.The drive are not recognized i n Bios,sometimes cause to freeze on start.What may be wrong ?,help.
Scrub a copper penny with a pencil eraser, then look at the tarnish a week or month later. Also touching the cleaned contact with oily fingers will cause contact problems later. Maybe good for return repair later, easy scrub head preamp contacts again to fix until next return..
This di right here is Just so you can pull the data out and toss the drive. It is not a long term fix.
thank you, a question, what happened if we keep it with just one diode?
next time there is a power surge, it will hit something more vital if you don't replace the TVS, otherwise its fine.
does replace pcb / board also fix slow reading hard drive? I have WD home studio hard drive which suddenly very slow reading and some files cannot be read, thanks in advanced
Hey I removed the diode but the multimeter still beeps. Did I do something wrong?
then u have anonther component that short out...find this!..i u remove the diode, check if the still shots out or if the diode could be ok! i have the same drive with the same problem but my doesnt spin on...i removed the bad component but still not spin
For clarity, all you did was remove the bad diode, correct?
yes
can it still do this with out the meter
Man i really aappreciate this video it saved my but how long can I use this driver without the diode
i have wd 1tb it has power surge issue i tried it different port and computer but it has the same power surge error..what to do?
How do I find the diode part #?
Hi..
I need help ASAP please.. my hard drive does spinn and i feel the motion of the inner parts even though its not detected by either bios or pc or any other pc.. what to do???? is it PCB board or head problem or what..
I have a Seagate where it no longer recognizes the HDD password, bedsides a platter swap at technical lab can switching the exact PCB get it working to get the data off??
if the drive spins - PCB is not a problem
yo, I received a factory new drive from Seagate and the motor doesn't spin up. It gets detected in the device manager, sometimes also in the disk management without any storage showing up for it. I actually ordered two units, both of them seem to be from the same charge, although the PCB of the defective drive looks a bit discolored. I tried that one first in my external drive enclosure and it didn't spin up, so I assumed my external enclosure was defective (many reported cases of not detecting drives with more than 2TB of storage). I dropped the other drive in there and it worked without an issue, so I guess my one of the new HDDs is simply defective. Do you have any thoughts on that?
so i checked my drive and i have a short circuit, so if i take off the diod i can than make a copy and than ditch the old drive how should i do it?? what programms should i use?
remove the short, and copy the data out. no special soft needed
I have this drive and it died! spins up fine - sounds normal - windows and bios do not see it - i removed the pcb and cleaned the contacts - same problem - any idea what could be wrong?
My bios recognizes the drive but I cannot find it while in Windows. Any tips?
how about no sounds dioda test but disk not spin & detect
Hi my PC hard drive spin and recognized but it doesn't show capacity how can I solve this problem with my PC hard drive. Thanks advanced
is there any software to recover the hard disk data
Hey man, I have the same drive, I just uploaded a video of the boot process. Is it toast?
hello sir, my hard drive is spinning. do you have any idea what to do? it's light stays solid blue but the computer is not detecting it.
i have replaced bios from one pcb to another pcb. Source pcb is kc48 and toner pcb is kc66. after changing bios the hdd detect but after few sec disconnecting .... what is the problem?. how i solve this issue?.
The mailman smashed that Priority Box because he liked it. 🤔
I have this exact drive and the exact diode tested bad, I removed the diode and the path tested good. The other diode/path tested good. The drive still does not spin up. What would you recommend the next steps be? I don't have a lot of internal experience on HDD Recovery, but I work with computer and am pretty comfortable around most things computer related. Any advice or assistance would be appreciated. Another note, I only have one of these drives, so I cannot currently take out parts from one and put in another. If that is a viable option, let me know and I'll look at picking another drive up. Thank you in advance.
you need to look for another possible short
HDD Recovery Services is another short an easier fix then another option? The stuff that you do is very inspirational and I would like to get more in to this line of work. Great content and video production.

hi i got a hard drive 160 gig maxtor spins computer not reconize it also board get hot is it the board
Hi bro. Do u still reply? I have exact same hdd like in that video. 2TB, can i just replace pcb with same model but different capacity with it?
Yes you can, but firmware needs to swap. EEPROM chip from original goes to the donor
@@hddrecoveryservices bios chip right? thanks bro. btw i have comment on your latest video. hope to hear your answer soon 😁
Would really appreciate an answer to this. You use special software after to look at the sectors etc, is this necessary or could you just plug it in and use as normal?
How much do u chge to recover photos on 5tb which died at 3tb--photos?
