SATA-II disk wont show in windows XP

[Kitarn]

Hi

I've been having trouble installing a new Western Digital Caviar 500GB SATA-II disk to my system. I'm currently running two 150GB Western Digital disks in Raid 0. The problem is the new disk wont show up in Windows Xp. The bios is picking it up fine... It's just windows. I've tried Disk Manager and nothing.

I even tried the disk in my other PC and it works fine.

Does anyone know what the problem might be?

Thx

Got it working now. It was because Raid was enabled for ports 3 & 4.
Doh'

Thank for the help!
