wow, i've only had maxtor and WD, and three of the five WD's i've owned have failed. granted, these were older (1 160GB, 2 40GB) drives, and all but the 160 were not actively being cooled. so i'm extremely leery of WD, even though they seem to have a pretty good rep everywhere else.
seagate has always had the best reputation otherwise, and my next drive will be one of the new perpendicular drives, probably just a 320 for now.
