I pretty sure can tell you that it is *not* an issue with your hard disk 
(Western Digital), but rather with the hard disk controller (usually 
integrated in the motherboard). Indeed, the SATA protocol is 
standardized, so it should work for all disks.

However, the I/O API of SATA controllers is not standardized. On some 
motherboards you can change a BIOS setting to make it work. Look for 
"SATA support", and try changing it from "native" to "legacy" or vice-versa.

On some boards, both settings work, but legacy is much slower. I've also 
heard of a case where initially SATA didn't work (it was set to native), 
but where changing it to "legacy" and then *back* to "native" suddenly 
made it work...
