What model of Adaptec is it?  Is it ISA or PCI?  It may be that it's
not being seen if it's ISA due to your BIOS settings or that there's
no driver for the card.

The driver isn't being loaded.  We need to know which kind of SCSI
adaptor it is, or if you know which driver it needs, try

	modprobe drivername

For example, for an Adaptec 2942 using the AIC7xxx chipset:

	modprobe aic7xxx

That should load the driver and you should be able to see the drive.
