    Thanks, I'll consider using tar in the future! In this case though I
    need to check my diskdump restore failure:

    # dd if=/dev/pt0 of=/dev/hdb
    0+0 records in
    0+0 records out

    Any suggestions how to troubleshoot this?

    Would I be helped by the "full" mt command? Is there a pt driver that
    implements all (or most of) the mt command options?
