I purchased a Western Digital 250G SATA II HDD today (WD2500KS)
My motherboard is Asus P5VDC-MX, acording to Asus web site my motherboard suports SATA 3G, and to my knowledge this the the same as SATA II and should work?

I followed the instalation instructions from Western digital, Connected the cable, and the molex makeing sure not to use both power conectors. I use the tools from WD for instalation of a new drive, but its a no go. As soon as I boot, BIOS seems to be haveing a rough time detecting the SATA drive, it takes quite a while then finaly detects it as an IDE. Though it would not show up in the list of drives for the Data Lifeguard Tools. It apears to be invisible so I cannot formate or partiton it.

Help, what should I do to further Tshoot this problem, I do not have another machine with SATA connectors I can test the drive on.
