I have an ASUS A7N8X Dlx (2.0) motherboard. I have added a Highpoint 1540 SATA RAID controller to the system that I have running two 80 GB Maxtors and two 120 GB Western Digitals. I have set up the two 80 GB drives to be one striped drive using the RAID controller. I disabled the onboard SATA controller by the way because my SiSoft tests indicated that drives connected to the PCI connector were faster. Anyway, when I boot with the Windows XP CD I get a message the it can not format the drive. Anyone familiar with this. I am going to try to install XP on one of the non-RAID drives now and format the RAID drive and then install XP on it after that. If anyone has any suggestions though, please let me know.
