I've had the worst luck lately with electronic equipment. My 360 RRoD'd, then the Time-Warner modem started dropping 40% of packets. Those things got replaced, and now it seems I've lost an external drive. I've had the thing for several years--4, I think. It got a lot of heavy use, and it had my main download folder. It now clicks, spins down, spins back up and clicks again. I can't access it at all. Damn it to hell. Any chance a good whack would unstick whatever is stuck? Just a thought.
I'm downright paranoid now. I'm duplicating everything essential and irreplaceable to other physical drives, when I can think of what that may be. Chances are I'll never catch everything. Do the MTBF ratings equate to just a few years of continuous use? God, if this happens to C: or D:, I'm really screwed. My backup PC died catastrophically last year. *Sigh*
