Mark, that will not recover his dead drives, gent already said he placed
them into another computer and they were still not operational. Only option
is to find identical drives and try swapping the logic pcbs, still modrately
questionable. Third, but most expensive, is to send the defective drives to
a recovery company who have the techniques to recover the data.

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.

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.
