I bought a brand new one, then a used one shortly after that (visions of RAID in me head), but before I ever had a chance to do that. The new one died on me. I ended up trading em both (one broken, one not) for a Maxtor 7200 RPM 40gig which is still doing just fine as a storage drive for my SCSI setup. Although I had a 3 month old Maxtor (same series Plus 40) die on me too, that was a retail one from Best Buy.
Seems like it's basically the luck of the draw w/ HD's to me.
