Got a 60GB IBM drive that failed during operation. (Power loss?) And after that Windows wouldn't recognise it as a harddisk. Had to use my Amiga to overwrite some bad blocks before it could be recognised.
The anoying thing was that It crashed when I was doing a backup of another harddisk to it. :-x
Oh! Beware of P2P software like Kazaa. Kills your harddisk very fast if your not careful. :-(
