I have a conner scsc hard drive CFP 1080S attached to a WD7193 pci\scsi controller card. Both are identified in system manager and are ok. There are no yellow marks or red marks opposite each. The scsi drive shows up as drive D when I start the computer. It was working fine until last week. The drive is still recognized on boot up but I cannot access the drive. If I try to reformat the drive, I get a message no fixed drive. Can I salvage this drive and how? Thanks. MMN.
