I remember reading all the horror stories about Western Digital, but honestly, of probably the 10 drives of theirs I've used, 1 has died. Every other drive has worked perfectly, in fact, I have one in my machine now that is a little over 2 years old, and another one going on 8 months, both chugging along nicely. I also have a mess around frankenstein machine I built for testing Linux and whatnot that has an old 5 gig WD that still works fine. The rest of the WD's I've owned I either sold, gave to friends, or put in storage, neither failing on me.
On the other hand, I helped to build a server for an insurance company down here and we bought 4 IBM 60GXP drives to put on a RAID config. 1 failed on inital boot, two days later, two more died. We had to do a lot of replacing, but the current batch of IBM 60GXP's we have in the machine have been working fine so far.
