Adaptec RAID Installation Guide
The Adaptec controller BIOS reports a drive as a disk instead of a drive.
This condition can occur if SMOR is used to disable Boot Enable. If
you require access to disk drives connected to the Adaptec controller
during the boot process, set Bootable Devices to Normal.
