I had a Western Digital mod.WD1200 120gb and a mod. WD600 60 gb both

I agree with the other suggestions about buying two identical drives
and swapping the circuit boards. You could even use dead drives as
long as it wasn't due to a board failure.

When you tested the drives in the other computer, did you try them one
at a time with the jumpers set to single drive? It's possible for one
bad drive to stop the other one from being detected. Some WD drives
require different jumper settings for master with a slave and for a
single drive with no slave.

The motherboard does not seem to be affected. (I am using the computer
to write this). I have tried all kinds of slave/master jumper settings
on the drives and in combination with other drives or alone the
computer always stops on "detecting IDE drives" when using one
of the bad drives.
In another newsgroup, I was told that the "chokes" on the logic board
could possibly be bad. How do you identify these on the board?
I am also wondering since these were both Western Digital drives if
they may a component that is more sensitive to over voltage than
other drives.
Thanks for the replies.
