How to Replace a Hard Drive PCB for Data Recovery

Replacing the bios chip on a hard drive PCB for data recovery

[@jonathonbatkin6466]

I bought myself a heatgun and replacement PCB for a fried HDD. I swapped the BIOS chip over by following your video and to my utter suprise the drive span up and I got a 6TB drive back from the dead. I've renamed the drive Phoenix. Thanks :-D

Liked and subbed. Thank you for the tutorial. Ive done several of these with success. A few minor notes, if you will allow. Zoom in...way in. The distance leaves some to wonder. The flux is really important when removing any component. You didnt mention it in the first chip removal, but did in the second. More flux at 5:09. You showed having to move the chip, flux will help the chip magnetize to the contacts. :) Very nice work though. Screw that sucker back on and hope for the best...or at least good. Thanks for posting.

[@Actorsplace]

Thank you for this! Question... I received a replacement logic board from China for a WD HDD but, on swap out before replacing BIOS chip, the drive motor would not spin up. Because there is a slight bit of damage to the board I am wondering of there are larger problems with the board or if this behaviour is to be expected prior to BIOS replacement? Or is the motor chip probably bad?

[@romyggar]

Excellent Video! thank you !!

[@Dem0crazye]

Brother is there a chance the board would work with out swapping chips? My hard drives where water damaged so I am afraid of the what if.

[@LesChroniquesDeGeorge]

I saw the question was already asked but no answer? What temperature did you used ? Thanks

[@RearEntry]

great video, I wanted to know if I could still use the new pcb if I got rid of the old one that had the original bios. So far with the new PCB the drive spins but doesn't show on the OS. Thanks!

It's a good job. Thank you for this video helped me to enhance my skill in Electronic mostly about soldering an ic part. Thank alot for share this video. [Greeting for Indonesia] ^_^

[@needspractice]

Dude you are amazing man, hope you are successful and doing well. Another question. You can't use a firmware or bios or whatever transfer program like ch341 to simply transfer this critical information or program it into the donor board without doing the rework station swap is there? No worries if not, I already ordered everything I need from your video.

[@jdigi78]

Thank you! I'm sure the data could be transferred if it's erasable memory but the chip swap is much less technical

[@HitEmUpru]

What temperature you set?

[@needspractice]

Another question: I bought this hard drive as an external usb storage device. It has failed. I took the hard drive out of the enclosure and put a Donor Board PCB on the hard drive without swapping out the PCB Firmware Rom Chip. I did this in order to see just how bad the damage was on the drive before sending it off to a “professional recovery service”. It appears to be in great shape and spins up nicely however, windows see’s the hard drive but cannot access the data. My main question is can I swap out the PCB Firmware Rom Chip from the original PCB Board with a rework station myself or do I need professionals do it(because I connected the drive without the correct Firmware Rom Chip; First)? Does advance programming or something else need to be done besides replacing the Firmware Rom Chip. Please advise and explain why/why not. I read on another repair website that Seagate drives have to have a professional swap out the Firmware Rom Chip if you connected the drive to the Donor Board without swapping the Firmware Rom Chip first. Does something special have to be done or am I reading this wrong? The website does say that you can do it yourself at your own risk if you feel comfortable.

[@needspractice]

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.

Hi Joseph - thank you for the very clear video. I have a Seagate hard drive which I can "feel" spins up but the computer BIOS refuses to recognise the drive. The BIOS takes ages to load - a couple of minutes. I *think* the motor seems ok as the drive spins up. Do you feel that swapping the board (and the BIOS chip) would work? Or am I barking up the wrong tree? Many thanks, Alex.

What make and model of heat gun are you using? I have the same issue and want to make sure I get the right one.

[@jdigi78]

I used a cheap generic hot air/soldering iron combo for this video. Any hot air solder rework station will work, remember to remove the part from the new board first as practice since you won't need that chip after the swap

[@needspractice]

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.

Try 390C for both

[@brucedoig1583]

What temperature (Celsius) dd you set the air at to remove & replace the chip?

I tested on a old HDD PCB and had good success with 310 C (hard drive worked). I just used flux and the same solder. I'm interested, too, what temperature you recommend. I heard too low is worse.

Hi i wanted to replace my PBC's bios but i broke my old bios leg. What can i do now can you help me?

[@musicdaniels]

Hi, thank you for this video. Is it possible to avoid the swap of the bios chip by using a tool like ch341? The idea is to read bios data from the old bios chip and write to the new one.

[@ronarndt6722]

Yes, however, it depends upon whether the flash ROM (BIOS) is correctly recognized / selected within the flash programmer SW. I was able to do this on an older circa 2012 HDD, however, using two different flash programmer SW (on CH341a) I could not correctly identify the 25FU406C flash ROM on an HGST (Hitachi now WD) 1TB 2.4" as it appears WD has modified the flash ROM offset so when I attempted to use other common (LE25FU406BMA and W25P40) IC selections it only corrupted the test flash ROM so I will now have to attempt solder process. *** Warning ***I Strongly suggest you perform a backup of the donor HDD flash ROM (BIOS) first and re-flash back to the same donor BIOS and boot/access test (before) attempting to backup and flash the original BIOS to the donor BIOS else you could corrupt your original BIOS and it will become unusable (even with soldering process).

Joseph, could you please write a few words about your equipment. What kind of tool (hot air rework station) did you use in the video? And what was the temperature? How large should be the air volume? i'm asking this because some hot air guns have air volume regulator. And i don't know what would could be the safe operational mode. Thanks for the video.

[@jdigi78]

I used a generic 852D+ rework station, I don't remember the settings I used but I imagine it was around 380-400c. You should practice on spare parts to just get a feel for the proper airflow and temperature yourself.

Hi there, great video mate. This helped my uncle who's a dairy farmer. His HDD failed and we tried this after a few other things. I have another question though. I've a galaxy s6 that I currently can't access the storage on as the screen is not displaying and it's locked. When I plug it in it needs to be in debug mode to access storage but I can't because screen is blank and it wasn't set up before hand. I've got different software but Samsung's are encrypted so even though it's detected by windows I still can't get anything off it. I've tried to use a mouse but nothings working. It's basically like a usb I can't access. I think I might need to remove the flash or transplant into another s6. Any ideas? Thank you

happy to help! I'd just replace the phone screen before anything else, if it really is just the screen broken. Swapping chips in a phone is very different because it's likely encrypted and may use other parts of the phone for that encryption.

My questions are: - Can I use the hot-tip pen instead of the blower you are using. - Will the heat damage the chip in anyway - if I melt the soldering and it spreads and make the pins of the chip touch each other, will that cause a problem. You seem to do it very casually. - What is the cleaning liquid you used and why? - Can you advice me on how to do this with a hot-tip pen instead? Many thanks

I'm hoping the chip is easier than the one I practiced on.

[@jdigi78]

You should watch a soldering tutorial, you need to apply fresh solder to the tip to wet it so it makes good contact. Also to do this with an iron and not a hot air rework station you need something like chipquik, it stays molten longer so you can heat all the legs at once

if you're using a standard soldering iron try a product like chip quik. it's solder that stays molten longer. Otherwise try applying fresh leaded solder to the pins before trying to remove, lead free solder found in consumer devices can be harder to work with

Recap: 1-Looks like my original bios was erased. 2-Looks like my original bios was only partially copied over to the new rom.: 512K worth. 3-I have one PCB Donor Board that boots up the hard drive and keeps it running but o/s can't read the data. 4.

They did this as a courtesy. I have another pcb donor board that has supposedly a new rom with my original bios information transferred over to it. However, you can see here the "condition” of the original rom. I am hoping all the information can still be transferred from this rom. Its not beat up too bad right? Both pcb donor boards; the one with the original rom and the new transferred over with the information rom do not power up the drive at all. Zero, zilch, nada. I can post photos of the new rom and new board if needed as well however, it looks good I believe. If the information was transferred over properly.

[@needspractice]

I have a Seagate Archive HDD (Seagate (STEB8000100) Expansion Desktop 8TB External Hard Drive HDD - USB 3.0 for PC Laptop). It was in an external enclosure. I have several external hard drives including a WD. I may have accidently used my WD power adapter for my Seagate Archive HDD. Nevertheless, my Seagate Archive HDD is no longer working. I bought several of these Expansion Drives. I opened another one and it is a Seagate Barracuda instead of a Seagate Archive HDD. I was just hoping to have a Donor for parts but no luck there. I went ahead and ordered from an online website the exact match PCB boards to see if I can get this hard drive working by myself. I am not looking forward to sending this off to a Data Recovery Service, but I am thinking about it. If someone could help me troubleshoot this a little beforehand to see if I can get this working without having to send it off that would be greatly appreciated. Here are my thoughts. The drive is completely silent, there was never a horrific ending to the drive. Like it is spinning up and crashing, knocking, beeping, whatever. Just one day I plugged it in and nothing. Now here is the odd part. It seems like something is barely connecting because in keeps connecting and discounting in windows. You hear the Windows Notification that it connects and then disconnects. Sometimes it stays connected and you can see in “Computer Management” under “Disk Management” the drive. It is like it is barely connected on a sub low level. What will happen is that in “Disk Management” a window will pop up and say you must initialize a disk before Logical Disk Manager can access it. MBR vs GPT. Of course, after doing this, I get the error “The request could not be performed because of an I/O device error”. Disk 2, red down arrow, Unknown, Not Initialized Most of the time the partition data or the available space does not show up in disk management, but rarely it does show up, i.e., size of partition and available space to create a disk partition. However, even when that shows up it still gives me the error “The request could not be performed because of an I/O device error”. My thoughts are that the drive is fully functional, but I may have blown a diode or something. The hard drive was sitting in an enclosure and had an extra PCB Board that was a bridge between the power supply and the hard drive. This other PCB board on the external enclosure is working perfectly. I popped out another Hard Drive from another enclosure used it on the bridge and everything works perfectly. So, I am not sure how the Seagate Archive HDD failed even when the External PCB power supply which held it did not. This is what leads me to be that somehow the PCB Board is no longer working on the Seagate Archive HDD and this may be a simple solution. I ordered a new PCB Donor Board and was hoping all I must do is transfer the “Bios” and install the new Donor Board and everything works. My question is troubleshooting. Before messing around with my vital “Bios” chip. Can I just swap out my Donor Board to just see if power is restored and the drive spins up? I know I will not be able to access the Data however, I would be able to confirm that my other original PCB board is the main culprit. Then proceed to swapping the “Bios” chip on the Donor Board. Will swapping the PCB board without swapping the “Bios” chip cause any “Data” loss or damage the Seagate Archive HDD? Troubleshooting Steps -1 Order Donor PCB Board -2 Swap Original Board with Donor Board without Swapping Bios Chip -3 See if Seagate Archive HDD powers on whatsoever, spins, etc. -4 If powers on and spins up, swap out Bios Chip -5 If Bios Chip is swapped and drive is still not responsive begin consultation with “Data Recovery Service”. Another question is do I simply just send this off to a “Data Recovery Service” I would hate to swap out my Bios chip and make it more difficult for them to recover. However, if it is a simple PCB Board Swap and Bios Swap, I would prefer to do it myself. Please feel free to give me any other pointers. I am just trying to perform some basic troubleshooting tactics before sending this drive off for an expensive recovery. I just have a feeling that this might be as simple as a PCB Board/Bios swap because the drive was never dropped, and in perfect condition. It is not that old either. Thanks!

[@jdigi78]

There shouldn't be any data loss caused by swapping the PCB without the bios chips, if this is an external drive you can replace the USB3 to SATA PCB without needing to swap any chips. If that doesn't fix it though you may need to swap the PCB on the actual drive itself and its respective bios chip

[@needspractice]

@@jdigi78 wow, thanks so much for replying. Yes, I have three of these drives. I took apart two of them. I interchanged the USB3 to SATA PCB boards on the non working drive with no luck. The good hard drive works on both USB3 to SATA PCB boards but the non working hard drive does not. Therefore, I am thinking it is the PCB Board that is at fault. What are the odds that this is a PCB Board is the main issue and this can be resolved easily? I have a couple PCB boards on the way to play around with. I will practice first on a couple of dead drives (soldering, etc.) that I do not care about. However, I do want to be very careful. I will swap without bios chip first and then try with bios chip after practicing. I have read in extreme lucky cases you can just swap out the PCB board and it works. I doubt I will be that lucky.

I fried my 2tb Seagate barracuda from using wrong psu cables. I swapped boards with another drive I had and I felt the disk spin up so I bought a replacement board. Swapped over bios chip and it doesn't spin. Like what are the odds I got a bad replacement? Sucks man, I feel defeated.

[@jdigi78]

It's pretty likely actually. The boards are from junk drives so they are likely all untested. I'd say they're pretty likely to give a refund or just send you another if you tell them it doesn't work. Leave out the fact that you swapped the bios chip though. Probably a good idea to do the same spin test with the new board you purchased before swapping the chip

[@HollowPs]

@@jdigi78 Yeah I definitely should've tried to power it up beforehand, kicking myself for that lol.

It would always pop right off. Hopefully, I didn't destroy the chip because I know it will be party over if I did. I have sent the pcb board and bios chip to a repair facility for them to install the bios chip for me and send it back. Hopefully they still can but they might not be able to. The pins are still in great shape however, you can't read the numbering anymore therefore don't know which side to face the chip. yikes. I already contacted gilware and they said don't bother sending us the drive if the bios chip is fried. crazy huh. Aren't these companies suppose to be able to pull a rabbit out of a hat?

They said that my original ROM was too damaged, but they were successful at transferring the ROM information from my Original ROM to this NEW ROM. They checked twice that it was transferred over successful. Well of course it did not work. The drive is seen in windows but barely. It is doing the same thing before like the original problem. Completely and 100% silent. (I think all windows recognizes is the bridge that it is connected to). This is the weirdest part. I ordered some more PCB Donor Boards and if I put any of those on this hard drive the drive comes to life. It boots up twice or tries to read the drive twice and gives up. What dose all this mean? Did some how the original ROM get corrupted and is permanently damaged? Long Shot They suggest the file system could be corrupted and that this is almost 100% fixable. Connect PC Max 3000 and either get lucky and extract the data by bypassing the software lock because the drive is in defensive mode or rip the data off raw but will take a while (same as bypassing the locked codes). Recap: 1-Original PCB Board with Original BIOS in perfect shape (something happened): -Drive would not boot up, completely silent, not moving or humming at all. OFF. 2-New PCB Donor Board with random bios that is already on the board (Testing): -Drive boots up and tries to read but gives up and fails. 3-New PCB Donor Board with Original BIOS (I installed it myself, botched it up) -Drive would not boot up, completely silent, not moving or humming at all. OFF. 4-New PCB Donor Board with New Rom (Installed by professional, bios information transferred over) -Drive would not boot up, completely silent, not moving or humming at all. OFF. … What does all this mean? Something is corrupted with the original bios? How does the drive power up and try to read with a random donor board with whatever BIOS that came with it; but when it is connected with the original bios its dead as a door nail? I will be getting back my original pcb board and original bios/rom. I’m sure the ROM is in ruff shape but the information has been transferred over to a new ROM. So that is good at least. What are my options at this point? Is my data lost forever?
