In this video I show how I take a BIOS IC and swap it from a bad control board to a new control board. If you are not comfortable with soldering, don't try it. You could corrupt the data on the chip and render the chip useless. This video is intended as entertainment, so if you brick your hard drive I'm not taking the blame. Have a good one.

I hate that bios chips are even a thing... NO ONE is able to swap them from my donor board around where I live so I spent $100 to do it myself... Thanks for making this video.

GOod afternoon, hope be well, i have an HDD of 320 Wester digital caviar blue, at work i have one broken with the exact same board part. My HDD is recognized by the motherboard, but i cannot get access to the data or info of partitions and disk capacity, If i do the change of the board can i get back the info stored? if i disconnect the disk suddenly appears the capacity used but of course i cannot access.

Hello there, I'm working on a WD320BPVT-75JJ5T0 that was in a dropped laptop. It was unable to read/initialize. I swapped the head from a WD320BPVT-24JJ5T0 to it and it was able to show the Dell Recovery volume but was not able to pull any data off or initialize/mount it any further. Is there a step I'm missing that would help get it to initialize or maybe the replacement head needs to be from a similar -75JJ5T0 model? or need to possibly Hot swap PCB? Thanks.

@optimizelogicrepair2784 Год назад

Sorry, without seeing exactly how you replaced the head, it is hard to tell as so many issues can arise from that procedure.

@lordpro 2 года назад

please help me, I also have a dead board (2060-800055-002 REV P1) Purple 4Tb Ordered from China the same board with the same revision. I replaced the BIOS-a chip, but the disk is still not displayed in the system. In the Bios of the computer it is shown as but Gb. But during initialization, it issues an I/O error. How can it be repaired

@optimizelogicrepair2784 2 года назад

I would have probably tried to swap complete boards first. There could still be something wrong with original PCB.

@RearEntry 8 месяцев назад

Hello thanks for the great video I have the exact same issue but do not have the original PCB anymore. Is there a work around? Thanks!

@optimizelogicrepair2784 4 месяца назад

Not that I am aware of. Without the original BIOS, the drive will not have the correct parameters.

I let a shop change the chip but it shows still the wrong hard drive. The chip definitely got changed but it is as if it has the wrong board(new donor board) even if it has the BIOS from the old board. Any knowledge why this could be? Board was the WD 2060-800067-001

I'm going to attempt to do this to save a hard drive. I wonder how important is the size of the nozzle in the heat gun? I've bought a heat gun from amazon and the only nozzle it has is 9mm diameter. From your video it looks like the nozzle you used was smaller than that.

@optimizelogicrepair2784 3 месяца назад

Not super critical, I would put more effort in where you aim the nozzle. You could totally do it with a 9mm.

@stevebartosch8694 Год назад

I was encouraged to see that this can be done. However, my local shop is telling me that on my WD 12 TB MyBook (Helium Drive) which stopped spinning and makes no noise at all, that there are multiple chips to be swapped and the estimate is between $900-1800. I've already ordered a donor. (Western Digital WD120EDAZ-11F3RA0 12TB PN:2W10322 US7SAM120 Hard Drive IU HA500). Have you ever done the needed donor swaps on this one?

@ThisGuyChip Месяц назад

Hiya. Newbie here. I see that next to the BIOS chip it is marked as U12 on the pcb. Are all those marked as 'Uxx' bios chips as well? I was looking at a WD PCB and do see U21 and U23 quite close to the MOTOR IC. U22 seems to be next to the RAM/MEMORY I am looking high and low for MOSFET/FET chips but am not able to identify one. Any advice?

@VladTheImpalerTepesIII 11 месяцев назад

How do you know when hard drive failure is PCB failure or internal failure? I have seen videos where clicking hard drives ended up being a PCB failure, but everyone says clicking is always an internal/mechanical failure.

@optimizelogicrepair2784 4 месяца назад

Typically when components fail on the control board, the hard drive will not spin up or do anything at all, because the power has been cut to a certain area. If the TVS diode fails , there will not be power getting anywhere as they are designed to fail to protect the board, kind of like a fuse. Clicking is the sound coming from the heads, they are sweeping back and forth rapidly because they are searching for the place they left off sometimes because of a drop.

Oh, one last thing? On these PCB boards I know they have 2 sets of numbers, one that is actually on the pcb and the other is a sticker on the port. Does the sticker number have to be the same in order to use it as a donor board or can it just be the number on the board. Sorry about all the questions.

i have old seagate 1tb hdd with very important files on it. The motherboard is damaged but I am able to order the exact same model from China. I need to know if i replace the motherbard without switching the bios from the old motherboard, what would happen? Also what is actually the reason to switch the bios chip? I really need to access that files. Can`t I just replace the motherboard and access my files without switching the bios chip?

@optimizelogicrepair2784 4 месяца назад

No you cannot simply swap boards. The BIOS holds everything for the drive, like Serial number, head and sector info, Read/Write cycles and drive health. You must transfer the BIOS chip to donor from patient, or copy BIOS from patient and write to donor.

@VideoGameWasteland День назад

Great video! I have a WD Elements external HDD, that just won't power on. It'll power on with a new board, but then the computer won't recognise it. Is the only way to access my data to solder the old BIOS chip to the new board? I'm sorry for bothering you here, but WD are of no help, and I'm desperate to get my data back. Thank you. :)

@optimizelogicrepair2784 11 часов назад

Hello, if you are saying the hard drive will power on with a replacement board, then yes if you solder the BIOS IC to the replacement board I would say you have a pretty solid chance at getting your data back. If you have basic solder skills it should be pretty easy. Just make doubly sure that you know what you are doing as you could turn an easily repairable drive into a paperweight.

Cover all 4 legs on one side with a line of solder whilst keeping it hot with the iron, apply light pressure under the end of the chip and it should lift one side. Repeat the other side to remove it.

When one is about to change the BIOS, and place it on the other card, bone the donor card, the BIOS must have the same position that it had on the factory PCB, that is, the position of the 8 legs matters, alaves or to the right. ?

yes. position of the bios pins(legs) do matter. the little white dot on the board right by the bios chip shows where the first pin of the bios chip must go. bios chips also have little round marking on them denoting the first pin.

@optimizelogicrepair2784 Год назад

Was it dropped? typically drives that are candidates for chip swap do not work at all. Sometimes there is a diode that goes bad, sometimes the main motor controller. Start and stop humming could be a few things, like bearings, head misalignments, etc. First thing you could do is download a free app called crystal disk info. Then you can scan the drive. If issues are detected, it should give you an idea. If it has bad sectors, I'm afraid that is probably where DIY ends and I would recommend sending it out if data is critical.
