Hello, I found this board after several days of research and I am glad I did. Hopefully you guys can shed some light on how I could proceed here.
What happened:I'm an idiot and I hooked up my 3 internal HDDs to a new PSU (Corsair RM850) using an old Thermaltake modular sata power cable - and the result was no spinning, no sound, undetectable etc.
So i'm quite sure I used a cable that was mispinned for the PSU I hooked it in to.
There is no visual damage on the boards, I inspected them with a small magnifying glass, and I didn't smell any smoke or even heard the drives spin up, so my guess is i likely fried the diodes (and hopefully not the header preamps).
I have considered professional data rescue, but the quotes that were given me were all around 3000€ and one offered to try to check out and repair the boards first and inspection of the drives itself ranged quite highly. The most reputable one I was able to find, ontrack, would start at 1500€ because the drives are TB sized, so if I still want to eat I simply cannot afford this.
The boards / HDDs in Question:I'm going to provide generic pictures of the PCBs because my cellphone's camera is not good enough to take quality pictures.Seagate Barracuda 1TB ST1000DM003 / 10071520 REV B
WD RED 2TB WD20EFRX - 68EUZN0 / 2060771945-002 REV A
WD GOLD 6TB WD6003FRYZ / 004-0B36131
So I have bought replacement boards and don't worry,
I'll let a professional solder the ROM/Bios chips onto the donor PCBs I found a shop near me in Bochum, Germany, that specializes in cellphone and console repair and who clearly state they also do PCB repair work for these and the guy at the other end seemed trustworthy as he exactly knew what I was going to ask about the moment I talked about the HDDs and their boards, but I have some questions that remain and you guys seem very knowledgeable
1: The place I bought the boards from (and all others that I could find with 10071520 REV) are saying that for the Seagate Barracuda, and the WD RED have boards with revisions listed (A/B/C) are saying that the PCBs are compatible with each other when doing a BIOS/ROM swap.
Seagate had issues with firmware and their boards but as far as I can tell the ST1000DM003 is neither 7200.11 or Barracuda II / V - Looking at hddoracle and browsing through the threads here this seems to be the case - i'd be grateful if someone could confirm this here.
2: The WD Gold PCB (004-0B36131) does not provide any revision info, but from what I read there might? maybe? be some. It is also apparently a board either manufactured, or used, by Hitachi. The pcb is certainly a different design and has two rom chips rather than one, however I read that Hitachi likes to store the rom data in the main IC. According to this
https://www.data-medics.com/forum/threads/info-wd80efax-004-0b36131-hgst-hus726t6tale6l4-pcb.4027/ it should be fine however without a main IC swap. Anyone here have some experience with newer WD Gold models?
3: The WD Red (2060771945-002) is an older model, I think made in 2014/2015 and I've read that older WD HDDs are quite lacking in surge protection. Again, there are no burn marks on the chips or diodes as far as I can see with my eyes and a small magnifying glass, however I would like to ask if anyone who had experiences with this type of pcb what the chances are that the header preamp also took a hit?
4: For the de-soldering process, what kind of heat temperature and tools are recommended (iron/hot air)? I want to confirm this with the shop I'm going to give the boards to to avoid potential heat damage to the ICs, especially the smaller chips on the WD Gold drive (and with these chips would there be a special/different process?)
5: If the chipswaps don't work because of further damage, can anyone recommend a Germany based data rescue company that does not scam their customers?
6: Is there anything I haven't considered or that I am missing that would be important for a pcb swap attempt?
I tried to be as precise as possible and hope some Guru can bestow wisdom on me
Thanks for taking the time to read this guys.
