Burnt harddrive pcb replacement

[Kurt Clark]

On connecting my harddrive with a faulty "Molex to SATA" power cable my hard drive got smoked.
I need to recover data from this hard drive, I have checked out some videos on youtube which show that if we get an identical PCB of a hdd of same make model number, we can swap it however we also need to swap the bios chip from the faulty pcb on to the donor pcb and then connect the donor pcb into the faulty hard drive. (this is due to the fact the the bios chip stores some calibration related information for that specific drive).
I have one old drive from which I can extract the PCB, the pcb numbers of the faulty drive and the donor drive are matching

100788341 Rev C

However the drive models are not matching
Details are as under
Faulty drive
Seagate Skyhawk ST4000VX007
Donor drive
Seagate IronWolf ST4000VN008

Can I use the pcb from the Ironwolf and install it in the Skyhawk?

I'd check the hddguru forums. They specialize in this sort of stuff.

If you're going to swap the "bios" chip off the old PCB to the new one, I don't see why it couldn't work. Assuming that the drive info is stored on the bios chip and not one of the other ICCs. I wouldn't think the PCB itself would have any bearing on what drive it is as long as it's the same (which in your case it is).
