Hello,
I am new here and wanted to ask for some help please.

A friend asked me to take a look at a WD MyBook1.

It smelled smoky and would not run.

I took it apart and found that the WD5000AACS would not function even plugged into an external caddy.

I spent some time looking thru the forums about this and I removed the pcb from the hdd and found that the D4 was shorted and the ZERO ohm resistor was open.

I am guessing that an incorrect power supply was used and either over voltage or reverse polarity was applied to the hdd.

I am fearing that the only way to recover the data, if it is possible, is to send the hdd to a professional?

Any help would be greatly appreciated!

Thanks!

Michael

This is the usual result:

In your case you should be able to replace the PCB, after transferring the ROM at U12, if it exists. Hdd-parts.com is one PCB supplier who will include a ROM transfer in the price.

Thank you for the response and the links!

I will get in touch with hdd-parts.com on Monday.

Hopefully a pcb swap will allow me to recover her data.
