Three years on and off, I've been trying to recover my data on an old hard drive, didn't want to send it to a data recovery company, happened to stumble across your video, gave it a shot and boom, I'm in !!! Dude, thank you so much for this video, amazing help !! Cheers brother, keep up the good work !!
i dont mean to be offtopic but does any of you know of a tool to log back into an instagram account? I stupidly forgot the password. I would love any assistance you can offer me.
Holy cow I can't believe it !! Lacking all the tools except for my faithful T8 screwdriver, I deliberated for hours and watched your videos over and over. Searched the web for map of the Seagate PCB board so I could find the diode. My multimeter was broken. And I didnt have a hot air gun. So I just grabbed the diode, ripped it off, and plugged the drive into power... and the drive came back alive. Absolutely unbelievable, I can't believe it worked. This drive is from the 1990s. My wife's grandfather is going to be very happy about his recovered data. THANKS !!!
@@danrazART I did remove/replace the diodes the HDD is still not working I guess my problem is something different. I ordered a replacement PCB lets see if transferring BIOS will work. Fingers crossed
Last night watched your video very carefully,had a portable hard drive which I connect to wrong power cable 15 years ago and that was it just died, gave it to some computer guy back then but no luck,so this morning got my multimeter and start checking and found one off this fuses beeping, removed it like you did and that was it, start recovering all my files, pictures,videos with my kids and everything. thank you so much my friend

The diode acts like a fuse. It's normal state is to be open ("disconnected") but if there's an electrical surge, it fuse and short the circuit, essentially shutting it down in order to protect all the other remaining equipment (think like the button on a power bar). You cut it out and it's like it is in normal mode again BUT now you don't have any surge protection so that's pretty much only useful for exporting your data elsewhere but not for long-term usage of the drive itself.
@@DomDEngineer : My HDD in my desktop stop working and I tried to transfer files using Sata drive and the HDD did not spin. I think we had a power surge. I'm going to try this. Do I really need such an expensive multimeter that he has listed above? What was that gel he used to remove the diode? It looks very easy. Staples wanted $250 to retrieve my data.
@@finn8248 A multimeter cost about $20. I didn't use hel or heat to remove the diode on my external HDD, I used mini cutter pliers that the ends look like a bird's beak. I cut one end and bend the diode back and forth to break the other end. Only cut it out if the multimeter shows it as short.
Hey man, I had two drives dead which I almost threw in the trash ( 2TB and 1.5TB seagates greens ) and then I ran into this video by accident. Popped one side of that TVS up and guess what? The drives both work now. Thanks man! And keep up the good work!
thats awesome! if you want to use these drives for storage, maybe order replacement TVS diodes to put the protection in place again. Otherwise, the next power surge will blow out the preamp
I have a 2TB that's become a 3.86GB unallocated. I've tried Seagate SeaTools but it's not able to preform any test on the drive. I thought of using the entire back panel of another 2TB to try out, will that work as this video seems lovely but I'm scared
@@Colarocker I eventually did but nothing changed. Seagate sent me a message that I must send to a Recovery company and recovery isn't even guaranteed. I'm just praying for a miracle now
I knew watching your videos would be useful sometime. Just "fixed" a family member HDD by doing this. They already have another HDD no put the data into. Thanks man!
running into your channel was probably one of the best things that ever happened to me I'm messing around with this hard drive here and I'm going to try to get it going again but I'm thinking I'm going to have to buy a new machine to put it in after I get it fixed
Can you list a cheat-sheet on what I need to buy and do to get my drive working again? I watched the video but you don't clearly state was is necessary.
interesting, what I would like to know - is the drive usable afterwards & for how long or is it quick salvage the data & bin the drive ? also anywhere to get spare pcb's for drives? Thanks
Really do appreciate the help. So easy to follow and accurate. loved the way it was filmed. almost like i was hanging out with you in the office. really a big thumbs up. i won't be replacing the diode (or continue to use the drive).
This is exactly what my problem is. The hard drive to PC, or SATA to USB cable, was bad so my PCB on my drive was smoking. I am hoping if i buy a similar drive, i can connect the PCB of the new drive to the old one, and get my data back. Will this work? Correct me if I'm wrong, but the label of that hard drive looked simliar to mine. Is it a Western Digital 1TB drive?
Hello HDDRS, I think this is a similar story with our WD Blue 500GB Desktop HD which stopped working. No sound & not spinning and won't show up when plugged into another computer. I've never used a Multi-Meter before. What is the setting on it in order to read/find the possible bad diodes on the HD ? Also, what gel did you use to remove the diode ? How long do you have once the diode is removed to save the data on the HD ? I don't own a computer vacuum so what can I use instead of that ?
Awesome video and very helpful! Got my wife's old hard drive that had some pictures on up and running. Was able to back it up and put the data on to her new computer.
@@NevaramoWR I used Veeam Agent for Windows. It's a very good backup software. Had Veeam agent for Windows on my laptop so hooked her hard drive up to it with a external hard drive case and backed it up and then installed Veeam Agent for Windows on her laptop and restored the data. Edit: Veeam Agent for Windows is also free.
@@NevaramoWR No problem. When I backed up the data from my wife's hard drive to my laptop I had a extra external hard drive plugged into my laptop that I backed it up to. Then plugged that into her new computer, installed Veeam Agent for Windows on hers and restored all the data on to her internal hard drive. Good luck! You will need to create an account on Veeam to download it. Here is the link www.veeam.com/windows-backup-free-download.html
HOLY SHIT OT WORKED!! I had an early gen Seagate freeAgent goflex 2tb external hdd that I thought I had completely fried by accidentally plugging in the wrong power cable. It literally used the same plug as my laptop at the time, easy mistake. It had over a terabyte of data on it that I thought was gone. This was 2014 or 2015 when this happened. I kept it all this time just in case I could get it back. Just today I spent some time looking around on the internet to see if I could fix it. I am now transferring all the data to a new SSD. This was my answer! Thanks!
@@hddrecoveryservices Hey guys, I was just wondering which tools you would recommend for me to buy.. as I don't particularly want to buy the entire kit in the description. Thanks!
so you just removed diode and it can run without that diode? :D i red current flow from both sides on one dioede (D1) so i guess that one is faulty cause as i know it should pass current only on one side
I'm guessing that with the two diodes that it might be a Full Wave Rectifier - now is only a Half Wave, with enough filtration to straighten out the DC. (but with half of the voltage?). Or, maybe a Voltage Doubler, with the two diodes? Just odd that they would install a Secondary Diode - for nothing. $$$$$
These two diodes are TVS diodes and are there to protect the rest of the board from small power spikes/surges/etc. - with them removed, the drive will still operate, but no longer has any such protection.
Hey buddy thanks for the video I had a 2tb western digital external hard drive that I know it worked for me 1 week ago and I did the same thing as you did and it worked. All my daughters pictures and important documents. Thank you thank you very much you are the man.
Bulbul Raza yes I did it myself bought the stuff I needed and removed the little black chip and hoped for the best and it worked connected back to my pc and it worked
Were you observing polarity on the diode? Semiconductors only conduct in one direction. To really test a diode you swap leads to check reverse and forward bias.
same is happening tome ive watched the short and i do not know whats going on and i am unable to check for shorts on the bored but it came out of a DELL OptiPlex 757 and its a Seagate Barracuda 7200. 12 what do i do call you lot or something else
Go search for drive stiction. Have experienced that on several drives including a modern 2Tb sata drive. Decades ago I did this routinely to waken up drives that had been stitting idle long. I have several full height 5-1/4" drives that has not spun for many, many years now, and believe those will need that stiction fix to be able to spin up again. The fix involves fast rotating (twisting) the whole drive with your hand, then stop abruptly. This might be enough to free the platters from the stiction. Believe me, I have done that several times. For very old drives, I think this can be a "permanet" fix, but for new drives this might be the last resort to bring them temporarily back to life to enable the user to salvage data off the drive before discarding it. Or use it just for non-critical stuff after that.
@@shadrackongeri3810 Can happen. :) I have a Samsung drive in front of me that stopped spinning around 12 years ago. I kept it in my drawer ever since, and I have no idea what's on it.
@@for-real-tho I have a similar situation with a hard drive I did not realize I still had from back in 2004. Now, I just have to get me a T8 screwdriver evidently of course the stores are closed with it being Christmas LOL just my luck.
Great video, but I don't understand the process you used to remove the diode. What was that goo stuff? And did you then use hot air on it? Could you please explain that part a little more?
I figured it out. It's solder flux, and he did use a hot air gun. I just performed this operation on my drive and it did not fix the problem. The drive still does not spin.
I am going to try this today. The thing is, my hard drive makes a clicking noise, but it never spins anything, so I think this still could be the issue. A few times there was power outage, I am thinking a surge took out that diode maybe, and that it was semi functioning, and then just suddenly mostly died and went short circuit. It sounds like the actuator arm is attempting to move a tiny amount, like it's only in a tiny faint click, but the actual platters don't spin. I am getting out my old multimeter today, and going to test this particulate diode, I hope to god the thing starts its little sound once I do it. There is only one big lesson I guess at the end of the day, always stay on top of backing up files, don't assume that you can back it up next week.
a BIG THANK YOU for the video! After watching it I was able to make my HD spin again and saved me a lot of money and time by recovering the data on it!
MY DRIVE ACTUALLY WORKED AGAIN! THANKS FOR THE VID! Whatching both yours and Adamant IT's video got me to know about these TVSes. Had to do some extra googling tho, since my drive's a bit different but, now *IT LIVES!!!!* (just have to order another 0603 fuse & 12v TVS -took a while to find what I think is a good replacement-)
Cool vid! thanks. Shouldnt a nube then reverse the probes when checking the diodes? Are they part of a rectifier circuit and why will it run without the diode? My 500gb external Lacie is alive, but sounds like a metronome. whiring and click click click. Doesnt spin up. Any ideas where to start? Thanks so much
For normal diodes, yes, you should check both ways. These are more like safety fuses that fail instantly in case current is exceeded and become conductive, 0 ohms. What this does is shorts the power which will trigger high current draw from psu and it will shutdown. It also prevents the current from frying delicate components behind the fuse. User will then need to remove the hdd from his system.
I will be geting my rework station tomorrow. May I ask what heat setting is best for removing this PCB Board Firmware Rom Chip? It has a digital setting with three numbers on it so I would assume I could set it to the exact setting. I need both settings one for the soldering device and one for the heat gun part. It has two settings.
Just had this problem with a drive in a caddy today. I'm going to check it out but question is what you did to remove the diode. What was the stuff you put on and ow does it remove the component?
Thank you!!!! I could fix my HHD without even knowing how to use a multimeter!! (Had to check for another video for that). After all the processes, I connected the hard drive to the computer and started spinning again. I did a backup right away.
Alejandro that's Awesome! I was hoping you would have a moment to drop us some feedback on our Google page. It really helps to spread the word about what we do. Thanks in advance, and here is the link: g.page/r/CTI7VfqwndZhEAg/review
Great video! Thanks. I fried my 2TB WD Blue HDD by upgrading my PSU and assuming that all sata cables are the same (They are not). I found an open zero ohm resistor on the hdd pcb near the 5v supply. I replaced it with a piece of wire. There are 4 diodes on this particular model's pcb. ...not just a D3 and D4, but also a smaller D1 associated with D3 and a smaller D2 associated with D4. Can you tell me if the same rule applies to these two additional diodes, i.e., if it is assumed that no other damage has occurred, can all four diodes be removed?
Well, looks like this is where my journey ends. For everyone that has been thoughtful and kind. Thank you. Looks like with the unexpected crash of this hard drive and the mistakes that I have made, I will not be able to retrieve this data. I will hold onto this drive-in case technology changes in the future or if I become independently wealthy and can afford a “professional recovery service”. To all the negative people out there. Humans are human. We make mistakes even when we know better. My father has been in computers for over 50+ years in the military. I know a lot about computers and backups. Life got in the way. I have a lot going on right now and the last thing I need is smart aleck comments about backing up data. Anyhow, I hope everyone has a wonderful day and wish all of you the best of success in life.
Hello, I have a query. I have an old IBM travelstar HD which has been dormant for some years. 1/3rd of the spindle seems to be dented/collapsed(not sure how this has happened?? I can't think of better terminology to describe?! I am curious as to whether this could be brought back to life? I am based in Australia... and not very computery!
so far the video seems good - im not finished but glad i found this video! Gives hope on my drives doing the same. BUT i believe the beep on the meter beeps when there IS connection and will not beep if there is NOT connection. Can you please clarify? In residential electrical wire diagnostics, the beep sounds when there IS continuity. Testing a light switch for example, off position no beep. on position should deliver beep. In micro electronics - is it supposed to be open or closed? the first one did not beep which indicates a blown wire or no connection. If its supposed to be in the off position then the meter is reading no connection. If it is supposed to be connected the meter will beep if the connection is good. This is an extremely important factor, i know what its like staying up hours into the night or days in, seems like i see some traits of a late night. just saying - sound confuse people. I was just making sure the beeps are correctly explained.
Can you used a different Western Digital power supply board from another model as long as it is the same form factor? I have a WD5000AAVS-00ZTB0 and I know that WD5000AACS has the same form factor power supply board. All the Diodes on my HD tested fine for continuity however I do see something burnt on the board I think it is labeled as E16 on the board.
So if the PCB worked without the diode, what is the purpose of the diode in the 1st place? How many can be removed and have the drive still operate? What kind of test jig did you have on your PC that looked at the signals?
Thank you for this video. I got 2 data drives in my PC. One shows up and then disappears of the system in few minutes and one simply stops the computer from turning on. I checked the diods loke you did but they are good. Any suggestions appreciated.
So if you can safely remove the diode to make it spin again, what is the diode used for on this PCB anyway? I mean, it should have some purpose, right?
Many thanks for a very interesting video.. I've recovered data from an external HD that was connected to the wrong PSU and fried the diode... What software do you use please
That software is by MRT Lab. It may be MRT Express. But it goes with a piece of hardware and the whole kit sounds very pricey as it will take you two years to pay for.
5:28 might want to call diode check in the forward bias method, that is where your red lead and black lead go. Does it work the other way? Otherwise, decent video thank you.
I have multiple shorted diodes..about 13 of them..it is cheaper to get a new pcb or can some of them test short based on the failure of another larger diode?
Also I bought a hard drive bay with a power source, it’s much different than the power that you use to start the HD. Could this be an issue as well? That I’m not getting power to the right part of the drive?
amazing how you made a video of an arbitrary package from n.y. and how you zeroed in on the defective diod on the pcb but you didn't explain that a diod is suppose to pass current in one direction only haven't read the other comments but i'm sure someone has mentioned just how amazing this video is but more than anything, it was the new wave music that did it for me
Hello! I've an old WD caviar HDD and it didn't spin up. D2 and D3 were dead, so I soldered them out. D2 pads now okay, D3 pads broken (no short, no voltage - nothing). I soldered another diode there (B240, not B140) and now HDD spins up but it's "clicking" like a turn signal. Do you have any idea whats the problem? thank you!!
Any chance you have a video or can tell me what diode's to test on a Seagate 100802503 REV A? Thanks for the video. At least I can keep testing and hoping I find a short.
@@hddrecoveryservices Thanks for the reply! I see two with a "D" on them. Both of them drop to zero and give a tone when I checked them. Does that mean they are both bad and is there even a chance it will work if I unsolder both? Thanks for the information and help.
Thanks but I don't see a D* w/ a number on the board. Not much is labeled. I did find a pic of the board online and hosted it here: ibb.co/9h6FydT If you could take a look and let me know what I should be testing and hopefully cutting out. If I can get it to spin up and be read, I've got a new drive waiting to copy the old files on. Then I just store this drive as a backup since it won't have any protection. Again, thanks for sharing your knowledge and helping people like me out!
Thanks for this awesome video explanation on testing PCBs! Excellent resolution and audio compared to anything I've seen anywhere!... Thumbs up ! Few questions though ... How do you know which diode to test and what is the next step if no diode seems to cause any issue? I understand no spinning issue can be caused by burnt motor, stuck heads, dead preamplifier .... How would you go about identifying these issues? Thanks in advance for any replies!
There are only a few diodes on there, so test them all. The easiest way to test what is wrong is to put a working (same part number) board on there. If the drive spins with it - then it's not the motor nor stuck heads. If EEPROM on U12 is external move it to the new board, and the new board will act like the original. If the drive clicks with this combo, then the preamp is also fried. If there is no U12 chip on original board (WD drive only) then you need specialized tools that can reconstruct the content and program new board with it.
Thanks for the tip, i just backed up my old HDD and bought a new gaming PC, went to plug in the old HDD and plugged in the wrong power supply, the WD drive isnt spinning, but im going to exacly what you did, as ive lost so much information, ill be back if it work soon, thank you so much for this tutorial
Love the vids! I have a 2Tb Seagate Barracuda st2000dm001 that doesnt power up. Ive removed the only diode that showed short with continuity test, nothing. Then ordered a replacement pcb, would the replacement not power up the hdd before swapping the 8 pin ROM chip? Starting to think its the motor... Any thoughts?
Don't know if you can answer this, or if you'll even see it, my WD has the same problem, wont spin, and when i put my multimeter on the diodes, d4 and d3, none of them gives me a reading, is it possible that both of the diodes could be dead? and would it work if i removed both? i might have a weird multimeter, it doesnt beep as well, It's a dt-830B digital multimeter, it measures a 9V battery just fine though. Thanks.
I have a Seagate ST320410A. I don't know where I got it. I connected the molex connector and promptly got sparks. I have used an Ohm meter and there appears to be a short between 12V pin and gnd. Reading of about .007Ω. There are two SMD near the power connector. a 1020f and Buf c116 I'm not sure which to remove. Suggestions?
Great info. I have a Samsung 250Gb that spins up heads move after 5 sec. stop completely and motherboard never see it . I already replace PCB swapped bios but same problem remains. Donor works fine with exchanged PCB. What could be problem motor, heads or damaged platters? I have two disks more same model same firmaware version. I like to practice on one of them to replacing head and/or replace platters. have open the HD PCB donor and I have seen it only has one head and one platter I am wondering what is less risky to exchange head or exchange platters? Any comment is appreciated. Best regards.

It's normal state is to be open ("disconnected") but if there's an electrical surge, it fuse and short the circuit, essentially shutting it down in order to protect all the other remaining equipment (think like the button on a power bar). You cut it out and it's like it is in normal mode again BUT now you don't have any surge protection so that's pretty much only useful for exporting your data elsewhere but not for long-term usage of the drive itself.
@@DomDEngineer : My HDD in my desktop stop working and I tried to transfer files using Sata drive and the HDD did not spin. I think we had a power surge. I'm going to try this. Do I really need such an expensive multimeter that he has listed above? What was that gel he used to remove the diode? It looks very easy. Staples wanted $250 to retrieve my data.
@@finn8248 i tried this and mine still doesn't work
@@finn8248 A multimeter cost about $20. I didn't use hel or heat to remove the diode on my external HDD, I used mini cutter pliers that the ends look like a bird's beak. I cut one end and bend the diode back and forth to break the other end. Only cut it out if the multimeter shows it as short.
Hey man, I had two drives dead which I almost threw in the trash ( 2TB and 1.5TB seagates greens ) and then I ran into this video by accident. Popped one side of that TVS up and guess what? The drives both work now. Thanks man! And keep up the good work!
thats awesome! if you want to use these drives for storage, maybe order replacement TVS diodes to put the protection in place again. Otherwise, the next power surge will blow out the preamp
I have a 2TB that's become a 3.86GB unallocated. I've tried Seagate SeaTools but it's not able to preform any test on the drive. I thought of using the entire back panel of another 2TB to try out, will that work as this video seems lovely but I'm scared
@@tdemjayz if you tried it, can you tell us about it here please? i have the same problem with a 3TB at the moment but i dont have a second panel :/
@@Colarocker I eventually did but nothing changed. Seagate sent me a message that I must send to a Recovery company and recovery isn't even guaranteed. I'm just praying for a miracle now
I knew watching your videos would be useful sometime. Just "fixed" a family member HDD by doing this. They already have another HDD no put the data into. Thanks man!
there you go!
running into your channel was probably one of the best things that ever happened to me I'm messing around with this hard drive here and I'm going to try to get it going again but I'm thinking I'm going to have to buy a new machine to put it in after I get it fixed
Let us know how it goes!
Can you list a cheat-sheet on what I need to buy and do to get my drive working again? I watched the video but you don't clearly state was is necessary.
interesting, what I would like to know - is the drive usable afterwards & for how long or is it quick salvage the data & bin the drive ?
also anywhere to get spare pcb's for drives?
Thanks
sweet video. thanks. tested both diodes on my failed HD. first one was bad. pulled it off. works like a charm now. recovered all data.
Thats awesome!
Really do appreciate the help. So easy to follow and accurate. loved the way it was filmed. almost like i was hanging out with you in the office. really a big thumbs up. i won't be replacing the diode (or continue to use the drive).
This is exactly what my problem is. The hard drive to PC, or SATA to USB cable, was bad so my PCB on my drive was smoking. I am hoping if i buy a similar drive, i can connect the PCB of the new drive to the old one, and get my data back. Will this work? Correct me if I'm wrong, but the label of that hard drive looked simliar to mine. Is it a Western Digital 1TB drive?
Hello HDDRS, I think this is a similar story with our WD Blue 500GB Desktop HD which stopped working. No sound & not spinning and won't show up when plugged into another computer. I've never used a Multi-Meter before. What is the setting on it in order to read/find the possible bad diodes on the HD ? Also, what gel did you use to remove the diode ? How long do you have once the diode is removed to save the data on the HD ? I don't own a computer vacuum so what can I use instead of that ?
Finally I know why my HDD is not spinning. It's SSD 😂
🤣
I'm to the point where I'm like what's a HDD? lol SSD for life!!!
🤣🤣🤣😂 are you kidding
Awesome video and very helpful! Got my wife's old hard drive that had some pictures on up and running. Was able to back it up and put the data on to her new computer.
you are welcome Brad
which software did you use to back up the data after performing this solution?
@@NevaramoWR I used Veeam Agent for Windows. It's a very good backup software. Had Veeam agent for Windows on my laptop so hooked her hard drive up to it with a external hard drive case and backed it up and then installed Veeam Agent for Windows on her laptop and restored the data. Edit: Veeam Agent for Windows is also free.
@@brad7648 Thanks alot bro. I'm gonna give it a go
@@NevaramoWR No problem. When I backed up the data from my wife's hard drive to my laptop I had a extra external hard drive plugged into my laptop that I backed it up to. Then plugged that into her new computer, installed Veeam Agent for Windows on hers and restored all the data on to her internal hard drive. Good luck! You will need to create an account on Veeam to download it. Here is the link www.veeam.com/windows-backup-free-download.html
What settings do you have to make with the multimeter? Does it matter with which cable you measure back and front?
Could you buy a PCB board to replace the one that might have a bad diode? Would you need the exact board for the model of the HDD you own?
HOLY SHIT OT WORKED!!
I had an early gen Seagate freeAgent goflex 2tb external hdd that I thought I had completely fried by accidentally plugging in the wrong power cable. It literally used the same plug as my laptop at the time, easy mistake.
It had over a terabyte of data on it that I thought was gone. This was 2014 or 2015 when this happened. I kept it all this time just in case I could get it back. Just today I spent some time looking around on the internet to see if I could fix it. I am now transferring all the data to a new SSD.
This was my answer! Thanks!
Brilliant! Exactly what fixed my disk. Every item intact. Thank you!!!
Your welcome
@@hddrecoveryservices Hey guys, I was just wondering which tools you would recommend for me to buy.. as I don't particularly want to buy the entire kit in the description. Thanks!
so you just removed diode and it can run without that diode? :D i red current flow from both sides on one dioede (D1) so i guess that one is faulty cause as i know it should pass current only on one side
I'm guessing that with the two diodes that it might be a Full Wave Rectifier - now is only a Half Wave, with enough filtration to straighten out the DC. (but with half of the voltage?). Or, maybe a Voltage Doubler, with the two diodes? Just odd that they would install a Secondary Diode - for nothing. $$$$$
These two diodes are TVS diodes and are there to protect the rest of the board from small power spikes/surges/etc. - with them removed, the drive will still operate, but no longer has any such protection.
Hey buddy thanks for the video I had a 2tb western digital external hard drive that I know it worked for me 1 week ago and I did the same thing as you did and it worked. All my daughters pictures and important documents. Thank you thank you very much you are the man.
I am glad it helped you Chris
Hey Chris, did you do it yourself? It's the same for my HDD and I'm really upset for the last few days because of it.
Could you please help me out.
Bulbul Raza yes I did it myself bought the stuff I needed and removed the little black chip and hoped for the best and it worked connected back to my pc and it worked
Bulbul Raza pm me and I’ll see what I can do
This video deserves a subscription.
About the video, so the drive works without the diode? What is the purpose of the diode then?
Suppression. It takes a hit the first time it happens, so more important components do not get damaged
So you don’t have to replace the diode first?
for repair you would want to, but I just ripped data off then the drive is done.
Were you observing polarity on the diode? Semiconductors only conduct in one direction. To really test a diode you swap leads to check reverse and forward bias.
same is happening tome ive watched the short and i do not know whats going on and i am unable to check for shorts on the bored but it came out of a DELL OptiPlex 757 and its a Seagate Barracuda 7200. 12 what do i do call you lot or something else
What did you put on the ends of the diode to soften it to release it.
Soldering flux
This just gave me new hopes for my old Fujitsu HD that stopped spinning 20 years ago.
Did I hear 20 yrs ago?
20?
Go search for drive stiction. Have experienced that on several drives including a modern 2Tb sata drive. Decades ago I did this routinely to waken up drives that had been stitting idle long. I have several full height 5-1/4" drives that has not spun for many, many years now, and believe those will need that stiction fix to be able to spin up again. The fix involves fast rotating (twisting) the whole drive with your hand, then stop abruptly. This might be enough to free the platters from the stiction. Believe me, I have done that several times. For very old drives, I think this can be a "permanet" fix, but for new drives this might be the last resort to bring them temporarily back to life to enable the user to salvage data off the drive before discarding it. Or use it just for non-critical stuff after that.
@@shadrackongeri3810 Can happen. :) I have a Samsung drive in front of me that stopped spinning around 12 years ago. I kept it in my drawer ever since, and I have no idea what's on it.
@@for-real-tho I have a similar situation with a hard drive I did not realize I still had from back in 2004. Now, I just have to get me a T8 screwdriver evidently of course the stores are closed with it being Christmas LOL just my luck.
Great video, but I don't understand the process you used to remove the diode. What was that goo stuff? And did you then use hot air on it? Could you please explain that part a little more?
I figured it out. It's solder flux, and he did use a hot air gun. I just performed this operation on my drive and it did not fix the problem. The drive still does not spin.
I am going to try this today. The thing is, my hard drive makes a clicking noise, but it never spins anything, so I think this still could be the issue. A few times there was power outage, I am thinking a surge took out that diode maybe, and that it was semi functioning, and then just suddenly mostly died and went short circuit. It sounds like the actuator arm is attempting to move a tiny amount, like it's only in a tiny faint click, but the actual platters don't spin.
I am getting out my old multimeter today, and going to test this particulate diode, I hope to god the thing starts its little sound once I do it.
There is only one big lesson I guess at the end of the day, always stay on top of backing up files, don't assume that you can back it up next week.
Did you replace the diode or just remove it
a BIG THANK YOU for the video! After watching it I was able to make my HD spin again and saved me a lot of money and time by recovering the data on it!
Amazing!
You are God send. Thank goodness I saw this video and I was able to fix a Seagate green HD.
well this gives me hope.. my 1tb nas is not responding.. :(
MY DRIVE ACTUALLY WORKED AGAIN! THANKS FOR THE VID!
Whatching both yours and Adamant IT's video got me to know about these TVSes.
Had to do some extra googling tho, since my drive's a bit different but, now *IT LIVES!!!!*
(just have to order another 0603 fuse & 12v TVS -took a while to find what I think is a good replacement-)
Didn't wanna lose another 4TB drive.
Cool vid! thanks. Shouldnt a nube then reverse the probes when checking the diodes? Are they part of a rectifier circuit and why will it run without the diode? My 500gb external Lacie is alive, but sounds like a metronome. whiring and click click click. Doesnt spin up. Any ideas where to start? Thanks so much
For normal diodes, yes, you should check both ways. These are more like safety fuses that fail instantly in case current is exceeded and become conductive, 0 ohms. What this does is shorts the power which will trigger high current draw from psu and it will shutdown. It also prevents the current from frying delicate components behind the fuse.
User will then need to remove the hdd from his system.
Great video, I have the same problem with a Seagate Barracuda of 1 TB, but you don´t say if you replace the Diodo, can you answer please. Thank a lot.
If you want to use the drive again preferably replace it with same one.
What's the stuff you added to remove the diode please?
Thanks for the tip man. Had the exact same diode blow. Popped it out and drive fired right up. All my files are gone but at least the drive works now.
Glad I could help
Hello and thanks for the video...at 5:38, you appear to add Flux and heat the contacts...is that a regular heat gun you are using? Thanks.
We use quick DW861 hot air stations
Found the right one, removed and worked great! Thank You so much. Does my Electronics Engineer degree come in the mail now...or..?
I will be geting my rework station tomorrow. May I ask what heat setting is best for removing this PCB Board Firmware Rom Chip? It has a digital setting with three numbers on it so I would assume I could set it to the exact setting. I need both settings one for the soldering device and one for the heat gun part. It has two settings.
Just had this problem with a drive in a caddy today. I'm going to check it out but question is what you did to remove the diode. What was the stuff you put on and ow does it remove the component?
Thank you!!!! I could fix my HHD without even knowing how to use a multimeter!! (Had to check for another video for that). After all the processes, I connected the hard drive to the computer and started spinning again. I did a backup right away.
Alejandro that's Awesome! I was hoping you would have a moment to drop us some feedback on our Google page. It really helps to spread the word about what we do. Thanks in advance, and here is the link: g.page/r/CTI7VfqwndZhEAg/review
I don't know how somebody can hit the 'unlike' button, the whole content is good as fuck, haters gtfo, and go to see something other. Good job buddy
What's the name of the software you use?
Good video, quick repair. One question, why did you not replace this tvs diode ?
Great video! Thanks. I fried my 2TB WD Blue HDD by upgrading my PSU and assuming that all sata cables are the same (They are not). I found an open zero ohm resistor on the hdd pcb near the 5v supply. I replaced it with a piece of wire. There are 4 diodes on this particular model's pcb. ...not just a D3 and D4, but also a smaller D1 associated with D3 and a smaller D2 associated with D4. Can you tell me if the same rule applies to these two additional diodes, i.e., if it is assumed that no other damage has occurred, can all four diodes be removed?
Well, looks like this is where my journey ends. For everyone that has been thoughtful and kind. Thank you. Looks like with the unexpected crash of this hard drive and the mistakes that I have made, I will not be able to retrieve this data. I will hold onto this drive-in case technology changes in the future or if I become independently wealthy and can afford a “professional recovery service”.
To all the negative people out there. Humans are human. We make mistakes even when we know better. My father has been in computers for over 50+ years in the military. I know a lot about computers and backups. Life got in the way. I have a lot going on right now and the last thing I need is smart aleck comments about backing up data.
Anyhow, I hope everyone has a wonderful day and wish all of you the best of success in life.
Hello, I have a query. I have an old IBM travelstar HD which has been dormant for some years. 1/3rd of the spindle seems to be dented/collapsed(not sure how this has happened?? I can't think of better terminology to describe?! I am curious as to whether this could be brought back to life? I am based in Australia... and not very computery!
so far the video seems good - im not finished but glad i found this video! Gives hope on my drives doing the same. BUT i believe the beep on the meter beeps when there IS connection and will not beep if there is NOT connection. Can you please clarify? In residential electrical wire diagnostics, the beep sounds when there IS continuity. Testing a light switch for example, off position no beep. on position should deliver beep. In micro electronics - is it supposed to be open or closed? the first one did not beep which indicates a blown wire or no connection. If its supposed to be in the off position then the meter is reading no connection. If it is supposed to be connected the meter will beep if the connection is good. This is an extremely important factor, i know what its like staying up hours into the night or days in, seems like i see some traits of a late night. just saying - sound confuse people. I was just making sure the beeps are correctly explained.
Great video, just did the exact same procedure on my WD hard drive and was able to recover all my pictures. Thanks!!
Glad it helped!
What type of software do you use?
I use a lot of different ones but most of the work is done in PC3000 and data extractor
Can you used a different Western Digital power supply board from another model as long as it is the same form factor? I have a WD5000AAVS-00ZTB0 and I know that WD5000AACS has the same form factor power supply board.
All the Diodes on my HD tested fine for continuity however I do see something burnt on the board I think it is labeled as E16 on the board.
Mine has 4 diodes, and 2 give a 0. (A small and a big one) Should I remove them both? I have this with a 8tb WD_black.
Awesome! thank you for this important video, put do you need to put a new diode? what material you used to remove the bad diode?
What was that stuff you placed on the diode first ? was that flux?? info on that please
So if the PCB worked without the diode, what is the purpose of the diode in the 1st place? How many can be removed and have the drive still operate? What kind of test jig did you have on your PC that looked at the signals?
It's part of the circuit protection layer
Wow looks so easy but ny seagate 2tb board looks different to the one in the video any tips where i should start please help
Thank you for this video. I got 2 data drives in my PC. One shows up and then disappears of the system in few minutes and one simply stops the computer from turning on. I checked the diods loke you did but they are good. Any suggestions appreciated.
what's that liquid gel you applied after removing diode D4?
You don't need to replace diode D4 with a new one?
that is soldering flux, very much essential for SMD work
So if you can safely remove the diode to make it spin again, what is the diode used for on this PCB anyway? I mean, it should have some purpose, right?
Many thanks for a very interesting video.. I've recovered data from an external HD that was connected to the wrong PSU and fried the diode... What software do you use please
That software is by MRT Lab. It may be MRT Express. But it goes with a piece of hardware and the whole kit sounds very pricey as it will take you two years to pay for.
5:28 might want to call diode check in the forward bias method, that is where your red lead and black lead go. Does it work the other way? Otherwise, decent video thank you.
👍
What liquid did you pour over that diode before removing it?
It's called flux. :)
Wondering why you didn't replace the diode
I have multiple shorted diodes..about 13 of them..it is cheaper to get a new pcb or can some of them test short based on the failure of another larger diode?
I saw it well. What is the name of the removed diode? I want to buy it, but I don't know the name.
When i test mine i can't get a beep at all? On the diodes but the drive quit spining???
Also I bought a hard drive bay with a power source, it’s much different than the power that you use to start the HD. Could this be an issue as well? That I’m not getting power to the right part of the drive?
amazing how you made a video of an arbitrary package from n.y.
and how you zeroed in on the defective diod on the pcb
but you didn't explain that a diod is suppose to pass current in one direction only
haven't read the other comments
but i'm sure someone has mentioned just how amazing this video is
but more than anything, it was the new wave music that did it for me
What was the goopy stuff he put on? And do I need it?
It's flux and it makes it easier to remove
did you replace the diode? i didnt see.
Forgive my ignorqnce but what eactly did you use to remove the diode ?
Hot air from rework station.
To remove the diode did u just heat it after u put that flux liquid? Ive pinpointed the dead diode but got a soldering kit can i just use a heat gun
Heat gun will probably burn the connector. Just snap the component off with side cutters or flat driver
Hello! I've an old WD caviar HDD and it didn't spin up. D2 and D3 were dead, so I soldered them out. D2 pads now okay, D3 pads broken (no short, no voltage - nothing). I soldered another diode there (B240, not B140) and now HDD spins up but it's "clicking" like a turn signal. Do you have any idea whats the problem? thank you!!
Diodes on a WD drive that won't spin seem fine with the multimeter. What other things could I try?
Any chance you have a video or can tell me what diode's to test on a Seagate 100802503 REV A? Thanks for the video. At least I can keep testing and hoping I find a short.
TVS Diodes are always located near power connector, and they look the same. Usually would be marked with D* and a number
@@hddrecoveryservices Thanks for the reply! I see two with a "D" on them. Both of them drop to zero and give a tone when I checked them. Does that mean they are both bad and is there even a chance it will work if I unsolder both? Thanks for the information and help.
Thanks but I don't see a D* w/ a number on the board. Not much is labeled. I did find a pic of the board online and hosted it here: ibb.co/9h6FydT If you could take a look and let me know what I should be testing and hopefully cutting out. If I can get it to spin up and be read, I've got a new drive waiting to copy the old files on. Then I just store this drive as a backup since it won't have any protection. Again, thanks for sharing your knowledge and helping people like me out!
Thanks for this awesome video explanation on testing PCBs! Excellent resolution and audio compared to anything I've seen anywhere!... Thumbs up ! Few questions though ... How do you know which diode to test and what is the next step if no diode seems to cause any issue? I understand no spinning issue can be caused by burnt motor, stuck heads, dead preamplifier .... How would you go about identifying these issues? Thanks in advance for any replies!
There are only a few diodes on there, so test them all. The easiest way to test what is wrong is to put a working (same part number) board on there. If the drive spins with it - then it's not the motor nor stuck heads. If EEPROM on U12 is external move it to the new board, and the new board will act like the original. If the drive clicks with this combo, then the preamp is also fried. If there is no U12 chip on original board (WD drive only) then you need specialized tools that can reconstruct the content and program new board with it.
Thanks for all this i,fo
Damn this is my dream to become data recover specialist...
Thanks for the tip, i just backed up my old HDD and bought a new gaming PC, went to plug in the old HDD and plugged in the wrong power supply, the WD drive isnt spinning, but im going to exacly what you did, as ive lost so much information, ill be back if it work soon, thank you so much for this tutorial
Love the vids! I have a 2Tb Seagate Barracuda st2000dm001 that doesnt power up. Ive removed the only diode that showed short with continuity test, nothing. Then ordered a replacement pcb, would the replacement not power up the hdd before swapping the 8 pin ROM chip? Starting to think its the motor... Any thoughts?
What we do after no more short and spining drive ?
Don't know if you can answer this, or if you'll even see it, my WD has the same problem, wont spin, and when i put my multimeter on the diodes, d4 and d3, none of them gives me a reading, is it possible that both of the diodes could be dead? and would it work if i removed both? i might have a weird multimeter, it doesnt beep as well, It's a dt-830B digital multimeter, it measures a 9V battery just fine though.
Thanks.
For the less adventurous are the boards replaceable?
Not replaceable, as I have been told, but if you have another board of the same type.........................
I have a Seagate ST320410A. I don't know where I got it. I connected the molex connector and promptly got sparks. I have used an Ohm meter and there appears to be a short between 12V pin and gnd.
