Hi,
I have a harddisk Western Digital model WD800JB, its a 7200RPM 80GB and
8MB cache disk.

I left my computer unatended and it was a hot day, so I think the
computer got overheated
and now the disk does not start up.
It was power but there is no spin, no sound no nothing.

The disk is not detected by the BIOS and the BIOS is stuck in the disk
detection stage.

I'm thinking in buying an exact model and exchange the green component
card on the bottom
of the disk.
I wonder if anyone have seen a harddisk like this, that appears death
and does not spin.

Thanks
Oliver

Yes, many people have. You should be aware that the board-swap
is only sometimes successful.

most likely it is not the board that is overheated it is the motors or
the fdb (fluid dynamic bearings) that seize up from the heat preventing
the spin. i would try what many people say is a myth but has works
about 50% of the time for me including on drives in your exact scenario
and that is putting it the freezer. put it in for about an hour. then
try it out. probably won't work but what have u got to lose?

I found the problem, a chip in the PCB just melted (a small black
spot).
I talked with some guy in ebay that clone the ROM of my PCB, so I'm
buying his
service. He have good reputation.

Also, I buyed a new WD800JB just to find out that the PCB is different
and it
does not fit my 2003 hard drive.

Anyway, will keep posting the final result in a couple of weeks.

I good think I found out is to always remove the PCB and check for
burned
chips. That should be the start if you drive does not start. It seems
that the
chip that was burned in my PCB is just the "spin chip".
