Hey Ben, I cannot speak from worldly knowledge of this but I have recently encountered serious issues with Maxtor ATA-133 IDE drives, model 7Y250P (beware!). Some drives have started failing after 30+ power cycles, and others have died simply by running the SMART self-diagnostic. I have gone through a half-dozen of them since February, and of course have started rotating them out of use completely. Then again, I have several WD drives at home that go through power cycles almost daily without problem. They are going on 4 years now. They just don't make 'em like they used to! I know this doesn't really help to answer your question, unless you happen to be running the above mentioned Maxtor drives. My $0.03 -- share the difference with Sebastian :) - Colin -- To err is human... effective mayhem requires the root password!
