I had a vaguely similar problem. When I first got the drive (second hand) I tested it in a P150 test machine running OpenBSD 3.4. It seemed to work very nicely there. I had some problems when I put it into my FreeBSD server though. It didn't seem to want to write more than 100MB or so even though I thought I was using the correct commands etc. Eventually though i came up with the following backup script and it works nicely... Might be worth trying, though it looks like you're using the correct command already... dunno. #!/usr/local/bin/bash echo "Starting the backup" for fs in $FILESYSTEMS do $DUMP -0au -f $NTAPE $fs done echo "Rewinding the tape" $MT -f $TAPE rewind echo "Ejecting the tape" $CAMCONTROL eject sa0 - -bash-2.05b$ cat /root/backup.sh #!/usr/local/bin/bash NTAPE="/dev/nrsa0" TAPE="/dev/rsa0" MT="/usr/bin/mt" DUMP="/sbin/dump" CAMCONTROL="/sbin/camcontrol" FILESYSTEMS="/ /var /backup" echo "Rewinding the tape" $MT -f $TAPE rewind echo "Starting the backup" for fs in $FILESYSTEMS do $DUMP -0au -f $NTAPE $fs done echo "Rewinding the tape" $MT -f $TAPE rewind echo "Ejecting the tape" $CAMCONTROL eject sa0 I'm using FreeBSD 4.9. - -- Cheers, Chris Howells -- chris@chrishowells.co.uk, howells@kde.org Web: http://chrishowells.co.uk, PGP ID: 0x33795A2C KDE/Qt/C++/PHP Developer: http://www.kde.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQE/6X6IF8Iu1zN5WiwRAs+iAJ9XEE1G8FPT2GSeaVjjJyqPmIZ7ywCeOnPP 5JJUdGkDlQLkx4fBYZznbfw= =RKjU -----END PGP SIGNATURE-----
