Hey there, I recently bought two new sata3 drives and set them up in a raid stripe and installed win7, all work fine. I added an older sata2 drive, it shows in the bios but Windows 7 cant see the drive.. not in disc management or device manager... I had a similar problem with my other sata2 drive but that one showed up in device manager as a 'scsi' and after a few reboots suddenly showed up in disc man. but after disconnecting that to try the other drive its now got the same problem. any ideas??
