Hello,

I have two of these units with the little chip that controls the motor burned.

(18 Dezembro 2002)
S/N: WMA8C3361943
MDL: WD1200JB-75CRA0
DCM: HSEANA24H
Firmware Rev.: 2061-001102-301C

I also have a good PCB (same revision 2060-001102-003) the layout is identical but chips are different, this PCB it is from a WD800JB.

I've tried change the good PCB, the motor start's to spin and it seems ok, bios recognize de drive, windows shows the drive at device manager but it doesn't appear to be accessible
because I can't see it at disk management.

I also have changed the 8 pin firmware chip from the bad PCB, and same results.

Please help me I need to recover precious data and i have no money to invest on professional data recovery.

So I thank you for all your suggestions.

check the hdd in MHDD or Victoria and post results here also try scanning the drives with these tools .

I've switched the good PCB from WD800JBHDD to WD1200JB and used MHDD, which "returns drive doesn't support LBA mode" and doesn't operate with it... what you think?

Have other question, why at HDD it says WD1200JB, but bios shows WD1200BB??

try change ROM from bad pcb to good pcb it will work .

He already do that… Possibility of head problem?

I think I’ve done that...
Is the rom chip a little "guy" with 8 pins?
So do you think that suddenly both drives have head problems?
I just think that the PCB isn’t the right one...
But you might be right...
I just wonder, both drives were fine and suddenly a lightning bolt ruined it.

What you think of that? I'm getting crazy and worst I can’t get the right PCB anywhere.

Thanks guys, you've been nice.
