I've got a Seagate HD which seems to have been the victim of a power surge
and now the PC will not even spin the fan if it's connected. Something to do
with the safety cut-out on the mainboard to stop damage. Is there any smart
workaround to recover any data from this disk?
As I cannot get the defective disk to allow even a boot up on any mainboard,
I cannot even run any utility to get anything off it..

The safety cutout is actually in the power supply. It wont
start if there is a short on the power lines it supplys.

Sometimes you can swap the logic card on the hard
drive from another good drive of identical model.

Not always tho, sometimes that still cant see the data
and whats inside the sealed enclosure may have got
fried by the power surge too, like the head preamps.

Worth trying a logic card swap if the data is moderately valuable.

Worth using a professional data recovery service is the
data is more valuable than that. Quite expensive tho.
 
Thx Rod , I've got another similar hard disk,

Its gotta be IDENTICAL, not just similar.
how do I swap the 'logic card'?

Basically just unscrew the screws holding
it on and unplug it from the rest of the drive.
Where is it?

On the bottom of the drive. If thats a Barracuda, it will
have a metal cover with blue foam under that, or a black
rubber mat covering it, depending on the exact model.

Its crucial that you only remove the screws for the logic card
tho, not the ones that hold the cover for the sealed enclosure.
Any resources on this?

Probably, havent bothered to look. The detail varys a bit
with the drive, particularly with the Seagate Barracudas
that the designers have chosen to cover the logic card.
Most other drives dont and the logic card is just the printed
circuit board which has the ribbon cable and power
connectors on one end and various integrated circuits, the
usually square or rectangular flat black things soldered to it.

I repeat tho, the drive has to be IDENTICAL.
 
the offending disk is a Seagate Barracuda ATA V 60 Gb so I assume
by your last post that for example, a Barracuda 40Gb won't do the job?

Correct. Even the same size isnt necessarily enough.
The rev level can prevent that as well.

I understand your comments about just removing the cover for the Logic
board. I guess I have to find a 60Gb disk first though......
