WD1000BB| WD 100GB IDE 7200rpm Hard drive
Reliable!
I have this same exact model, I purchased it in the summer of 2002, and it is nothing less than the most stable hard drive i have yet found.  I have had zero confilicts resulting from fault of my hardrive the whole time I have had it, and belive me I use my computer alllll the time, this is a really good harddive to buy, even though you may think it's cheap for a high quality hard drive, that only makes it better, I think this is the best hard drive to buy that's widely availiable right now!!
