Hi!

i've some problems with recover my girlfriend's hd. the hd is:

SN: 5PL0Z984
MODEL: ST9100825A

LOGIC BOARD: SPS-4078-46
DATACODE: 7J0654
?: 100385898 A C6401941
PCB: 100346102 REV B

100gb 2.5" PATA

the hd doesn't power up.

I looked for similar posts in the forum and i've already tested vst with multimeter with no lucky: somewhere there is a short but i can't figure out where it is. So i bought this hd:

LOGIC BOARD: TH COMPUTER #TH1066
?: 100374823 D 3645DQGZ
PCB: 100346102 REV B

100gb 2.5" PATA

I swapped the pcb and i tested it with no lucky. I can hear the the motor and the head but ubuntu or mac os can't recognize the hd.

So my question is, is the logic board wrong? I need to look for another logic board?

Thanks
