My name is in the topic of a thread! YEA!
I actually had no prior "warning", such as the disk spinning phenomenon, and can't really give much help since that drive is now in a garbage heap somewhere. Sorry to hear that I'm not the only one.
One theory for what had happened for me was that my unit's vents had been covered, forcing it to overheat in the drive, but I was a bit too hysterical with rage to check under my desk at the time
