I've used SCSI tape under Linux and other Unixes, but not scads.  First
thing I'd try though is cleaning the drive (use a cleaning tape), second
would be trying a second media unit to see if maybe there was something
wrong with the tape.  Third, I'd find someone who knows more about tape
processing and drivers than me to diagnose any remaining problems.
