- I have never had good success with getting the Adaptec to work. I have
- precisely the same symptoms as you describe, and with a similer
- environment -- only I have *two* IDE drives on my IDE controller, in
- addition to the SCSI drive. And I have a Wangtek tape drive. I have
- just about given up on getting the SCSI drive to work under OS/2 for
- now; I'm hoping that the 2.1 beta will behave better.
-
- Oh -- I do know this is not a hardware problem. The system works fine
- under DOS and Dell Unix.
