replacing PCB for maxtor diamondmaxplus 9

[lok]

hi all,

I have a Maxtor DiamondmaxPlus 9 80GB hd. An IC(W503) on the PCB was burnt with white fume and a little "light", seems due to bad power supply.
I want to get back my data.

I found some similar cases on the board, like this one,

it's the same hd as mine, and the same IC got burnt.

Here are pics of my hard disk:

So, I will try to find an PCB and replace it, though i know it dones't necessaily work since there might be something wrong in other parts. (seems its the easiest and an inexpensive way i can choose)

what i wanna ask is ,
How to choose a compatible PCB for my hd?
(if i get it from old hard disks, what code, KMBA, SN, TLA, and the code on the white label at the back are OK? )
(if i look for a PCB, what spec is OK?)

thank you for every help~

Any pcb with cpu Agere Ardent C8-C1 would work on this drive .

Thx, i 've done it.

I replaced the PCB of my hd with one of code YAR41BW0, N,M,C,A, (6Y080P0) .
My hd is YAR41KW0, K,M,B,A, 6Y080L0. It works out and i am able to access my data.

Good luck to all burnt Hard disk owener~
