I've always bought Seagate. Wouldn't even think of buying any of the cheaper stuff (Maxtor, WD). So, after one of my drive's in Obiwan went bad, I had to finally get off my butt and get an external HD for backups for one more level of sanity.

I bought one of the new Seagate Freeagent drives, a 500GB USB2 drive that could hold all of Obiwan.
