I have both a Sata (Seagate 500mB) and ATA Samsung installed in my computer. Vista installed on the Sata without problem and sees my ATA which I use mostly for backups. When I ran the install for Win 7 I installed on the ATA, install did not see the Sata. Now up and running I still cannot see the Sata drive. In device manager under storage controllers is a raid controller with an yellow exclaimation. Raid is disabled in the bios. Under the "Disk Drives" section of device manager only the ATA is there. I see the same driver in Vista and its working fine. Vista also shows my Seagate SATA installed as a SCSI device. I did try to find a driver unsucessfully for the raid controller M1573 (MSI RD480 Neo2 MB) but as I have it disabled in the bios don't really know why I'd need it? Any ideas? All my media files are on the Sata.
