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.
