Two things:

Make sure that the SATA disk is plugged into one of the two primary connectors located at the centre of the MOBO, and not in one of the 4 SATA RAID connectors at the bottom - see pg 2-22 of your manual.

Also make sure you have at least XP SP1 preferably SP2 installed

Nice motherboard.
