WD HDD PCB Swap, next step?
September 21st, 2010, 1:13
Hi
Sorry kinda new to the forum
I have a WD10EACS Western Digital HDD which i assume had the PCB burnt because when I tried to plug into e-sata, I didn't realize the e-sata power plug was inverted
now I got my hand on an exact match PCB (same pcb number both printed on board and sticker) and I manage to swap it and on booting it up, the hdd spin fine, no clicking sound no weird noise and windows could recognise a device has been plugged in, and now it requested me to initialize the disk
the problem here is that I do not really want to initialize the disk yet, because I don't want to lose the MBR and the data, is there anyway I can make sure that the PCB swap is successful? at the moment I couldn't tell what is the size of the HDD at all, Truecrypt software actually show that the HDD is of the size 512B, what does that mean? did the disc got destroyed too ?
some advice would be really helpful thanks

This disk has adaptive info stored in the processor from the original pcb.
The disk will not work without this info.
You have two options:
Repair original pcb, or read out adaptive info and write it into new pcb.
First thing is perhaps a possibility, second one is only for pro.

The PCB swap has not been successful, you need to program the PCB with the unique info from the original drive.
This data is stored inside the MCU (and also a copy on the platters themselves) and you cannot retrieve this data with the specialist equipment and skills required.
In this case if you want the data, then it does need to go to a pro. Assuming it's "just" the PCB it shouldn't be too expensive (for example we would charge no more than £195 for this, but we're too far away from you!)

ok i guess i'm doomed 
i'll just give WD hdd diagnostic tool a try and maybe try initialize the drive and see what happen

If you upload a detailed photo, one of us may be able to help you repair your board. Many times the problem is only a shorted diode, in which case it can simply be removed. That said, the photos that I've found of your model have locations set aside for TVS diodes, but these locations appear to be vacant.
