PCB replacement for WD external HD

November 8th, 2012, 9:51

My WD external drive stopped working, and it seems to me that the issue is caused by the PCB.
When I connect power, the hard drive does not spin up nor does it make any sounds. However, the PCB does get very hot when connected to power, and I suspect it is burned.
Therefore, I would like to change the PCB with a compatible donor. Somebody told me that this will only work in older models, because with newer models I will have to use professional equipment to copy the firmware to the doner PCB?
The specs are as follows:

WD5000AVJS-63TRA0
DCM: HHNCNV2CAB
Product of Thailand, 12 Aug 2007
PCB label: 2061-701477-100 04P XC 4U05 19CG H 0005050 8055

I would like to try buying a new PCB that matches the two first number series on the PCB label (2061-701477). Does anybody expect this to work?

Thanks in advance,

Martin

You get a new PCB, then what you want to do?

Post a pic of the other side of the pcb, to see what and how badly the pcb is burnt.
Success in DIY will be limited, if data is very important , take DR help.

Almost certainly will have no external ROM on this model.

DIY not an option.

Most modern HDDs store unique, drive specific "adaptive" information in a serial EEPROM chip. This chip, or its contents, needs to be transferred from patient to donor. In WD drives, this chip is usually located at U12.

However, some PCBs do not have a discrete serial flash memory chip. Instead they store the adaptive data inside the Marvell MCU (the largest chip). In this case you will need a "PCB adaptation" service.

The following PCB supplier includes such a service for free:

If your PCB looks like the following one, then you will require the above service:

Best of luck.
