Yeah those Deskstars or whatever the hell they're called died sad yet interesting deaths, just up and stopped working. The Seagates were the SAME model 80gb SATA drives, one was a replacement for the first, thus I do not recommend them at all. The Maxtors were older models, they still worked but couldn't be used for booting, and I have no idea why either. The one WD was used heavily for 4 years, so I don't blame it at all. As were the Quantum and Fujitsu drives, 5gb and 8.1gb respectively, used in an MP3 server back when MP3's were just becoming available.
IMO, I like WD, mostly cuz of the sales.
