Murphy" Message-Id: <199705311957.PAA00744@dunquin.bu.edu> To: hardware@FreeBSD.org Subject: Tape drive problems (Archive Anaconda) Reply-to: rdmurphy@bu.edu Sender: owner-hardware@FreeBSD.org X-Loop: FreeBSD.org Precedence: bulk I'm trying to backup up my system (so I can upgrade to 2.2.x, among other reasons). However, my tape drive is acting up: it seems to have trouble backing up anything of any size and then seems to render the tape it was using unreadable (and unwritable). Although I haven't backed up since Jan. (which was when I installed 2.1.6) I have used the drive regularly since last summer. I have an NCR controller and an Archive Anaconda QIC-1350 tape drive: (ncr0:6:0): "ARCHIVE ANCDA 2750 28077 -003" type 1 removable SCSI 2 I generate these problems with dump or tar: # pwd /A/home # tar -cvf /dev/rst0 rdmurphy (long file listing) tar: can't write to /dev/rst0: Input/output error # tar -tvf /dev/rst0 tar: read error on /dev/rst0: Input/output error # cd rdmurphy # tar -cvf /dev/rst0 illeg (shorter file listing, with a tape drive noise at end, no err.) # tar -tvf /dev/rst0 tar: read error on /dev/rst0: Input/output error This produces dmesg messages such as: ncr0: restart (ncr dead ?). sd0(ncr0:0:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8. sd0(ncr0:0:0): UNIT ATTENTION asc:29,0 sd0(ncr0:0:0): Power on, reset, or bus device reset occurred , retries:4 st0(ncr0:6:0): 200ns (5 Mb/sec) offset 8. I'd be quite grateful for any suggestions that anyone can offer. I'm overdue for a backup as it is and I'm also reluctant to upgrade without a recent backup.
