I have an asus p5k-e mobo, and have always had a RAID 1 array on it of Seagate 320 GB disks. This has always worked fine, but I thought I should get another HDD for storage and backup. It's a Samsung 1.5 TB drive. I hooked it all up, can boot just fine, but windows doesn't show the drive. BIOS shows it, as does my RAID building software. I have SATA set to RAID in BIOS, and I think that's my problem. I need to set it to SATA 1 and 2 as RAID, but SATA 3 as IDE. How can I do this? Any help would be greatly appreciated.
