Hello everyone,

as first time poster, let me thank anyone looking into my issue.
I did research of my own before posting it, but since this is my first attempt to restore HDD, I'm afraid I don't have enough experience and there are too many questions with very few answers.

Currently I have WD1600BEVT-88ZCT0, DCM: FHCTJHBB. There is some data on that drive, however, BIOS can't read it. There is no spin up sound either.
From my research, I believe I could save it by finding donor HDD. Most of guide are related to older version of WD drives, with DCM having 9 letters - since I'm having Marvell (version 2, if I'm correct), there is only 8 letters.

I found possible donor HDD (with bad sectors, BIOS/Windows successfully detects it). Donor model is WD1600BEVT-22ZCT0, with DCM: FACV2ABB.
From guides, it seems that those two are not compatible, due to TJ != V2, but I've decided to ask second opinion.

Any suggestion, or link to guide I could read on this topic, would be most appreciated.
Also, if those two are compatible, or when I find compatible one, how complicated would it be to fix original one, and is there any risk for data?

Thanks everyone

Need proper diagnostic first

If the drive doesn't spin up the DCM is not a factor (yet), but the PCB IS
which is: 701499 + need to transfer the ROM chip or its contents
Or take a multimeter and start examining the PCB, to find out what's wrong with it

Jermy, ROM is masked on MCU.

Hello everyone, sorry for my poor english, because i using google translator.

Oh no , then the OP has one choice left if he wants the DIY route,
To fix the PCB !

Jermy ,
Its Fun To Remove a QFP Main Chip Or a BGA Main Chip And Transfer It To Donor If You Are Sure Enough Its Not Fried .I Am Pretty Skilled With That BTW ,Will Post Lot Of Content Starting April [ When New Office Is Fully Ready ] .

I would have done too if I didn't had another choice, but because you can rebuild the ROM from SA why bother

These Denali drives are works sometimes with donor pcb without rom content swap. Enough if fw microcode is a same.
As i see, the donor and patien manufacturing date is close, so maybe microcodes are same.

rogi85: swap PCB, maybe you will be a lucky 1000/1 !

Thank you for feedback, it was very informative. I took some extra time to Google it a bit more, but can't say that I learned much (except that I might not be able to perform ROM chip swap with my present tools).

@saltwater I don't own donor HDD, and price for it is about 1/6 of professional HDD recovery. Do you think is it worth the risk? Not sure what "lucky" means

Is there maybe a guide how to check PCB? Eye examination showed that there is no visible damage. I could use multi-meter, but lacking instructions what/how to check.
