I have an HP SureStore 12000e tape changer hooked to an Adaptec AHA-2940W SCSI controller. I have been unable to get ArcServe 2K to backup or controll the devices - when I go into device manager, and click on the aic78xx controller, nothing happens - the more info and next buttons stay grayed out. The autoconfiguration of the device works fine, and I can read the tape volume name (not sure if I can retreive the data yet - now getting an invalid registration - please reinstall the product error - dang, I hate CAI's registration process.)
