This is strictly HEARSAY, so bear with me...
A friend of mine had been having problems with his WD hard drive (a 1.2Gig
drive, don't remember whether it was the 21200 or the 31200). He was running
FreeBSD. He did some digging and found that there were problems between
certain BIOSes and _some_ revisions of WD hard drive firmware. The pointer
that I have for "information" regarding how to fix this is:

I think that my friend said it was something about an interaction between the
Intel Triton chipset and WD drives (not just the ASUS boards that WD

So it would appear that it doesn't matter what operating system you are using.
My friend was using FreeBSD.
I would thoroughly read any docs that you find at Western Digital before taking
any action that might not be reversible. I am not an expert in this matter,
but thought that your story sounded suspciously familiar to a story a friend of
mine told (thanks to my friend Vlad for supplying me with all the info).
As a disclaimer, I have a Western Digital drive from a year or so ago, and it's
