I always assumed it was the computer cable or interface. Speaking of which...I am now well and duly fucked. My main desktop just died today, out of nowhere. I left it for 10 minutes, came back to see a black screen and a warning that the drive had exceeded RAID specifications...and the drive was making not just tick-tick noises, but *clanging* sounds, which makes me suspect that the arm on the hard drive has gone off, and there's physical damage. Anyone with solutions, let me know, but I suspect it's dead. I'm going to go to somebody to try and recover the data (suggestions?), meanwhile I've ordered a new system from Dell, but it won't be here until the 3rd, unfortunately. So I'm working off my laptop for the foreseeables. jms
