Re: [flexbackup-help] /dev/nst0: Input/output error

[Brian B. <bb...@my...>]

Thanks for the direction.  I'll try the things you suggested.  BTW, the 
following is the output of 'mt -f /dev/nst0 status':

SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x45 (QIC-3095-MC (TR-4)).
Soft error count since last status=0
General status bits on (41010000):
 BOT ONLINE IM_REP_EN

My drive is a Connor CTT8000-A (IDE drive that takes Travan TR-4 tapes.
