One more thing I forgot:

The power supply theory is very plausible, also. To check if it's OK,
you measure all four cables on any peripheral connector, to check for
+5, -5, and +12. Of course you'll not remain looking at your voltmeter
for a week, so if they measure OK when you check, and the failure is
random, you'll have to try to change the (complete) power supply. They
are a cheap part (around 50 bucks for a nice quality one). So try that
and if the problem does not go away, then there's nothing else to put
suspicions on. Just blame the drives.

Hope this helps,
