I might throw something out. If you spectulate that something on the
motherboard went bad instead of the drives, you would try them in another
computer, which you did. My question is first, could the other computer
handle the larger drives, and if so, since Western Digital drives have a
special situation with the master/slave jumpers, if you tried one at a time,
did you set it to single or take the jumper off.

Also, I did not see you mention whether the drives were making noise. Are
they running and cannot be read, or are they completely dead.

Do you have any idea what killed your power supply. Lightning strike or
just old.

Yes, he did say that. But I've seen too many instances where one error
was masked by another. So, it is worth a try. I'd think that a failed
power supply destroying both harddrives without damaging the mainboard
would also be unusual.

Try a "Clear CMOS". Could be a jumper for this, or just remove the
battery
for a bit. Re-install the battery and just turn the computer back on
and
let
it auto-detect everything. Worth a try anyway.

news I had a Western Digital mod.WD1200 120gb and a mod. WD600 60 gb
both
working fine until my power supply died. After replacing the power
supply bios will not detect either drive. I tried them in other
computers with the same result. The only thing I can assume is that
the power supply put out too much voltage and burned something
out on the logic boards.
Does anyone know if there is a fuse or resistor (hopefully) that
blows
in case of over-voltage in these models? Also, the logic boards on
these drives are super easy to remove with no wires to unsolder.
If I get a working drive of the same model and exchange boards
could
I recover my data? Is there anything that could blow inside the
sealed
drive with too much voltage?
I had some backup but I was also backing up from drive to drive
thinking "what are the odds both drives would fail at the same
time"?
Apparently, not that high.

There's too many variables to know, there could be a fuse of some
sort,
if
so it shouldn't be too hard to track down but you may be screwed.
With
some
luck you may be able to recover your data by swapping over a board
from
an
identical drive, I've had good luck with this in the past but drives
are
more advanced now so YMMV. Good luck.
