    I am trying to issue some commands to my tape drive to make sure I've
    got everything installed right.

    Tape drive info :
    Under /proc/scsi/ I see:

    # ls /proc/scsi
    scsi sym53c8xx

    # cat scsi
    Attached devices:
    Host: scsi0 Channel: 00 Id: 06 Lun: 00
       Vendor: ARCHIVE Model: Python 02779-XXX Rev: 658A
       Type: Sequential-Access ANSI SCSI revision: 02

    So logged in as root, I issue the following command and get the
    following response:

    # mt -f /dev/nst0 status
    SCSI 2 tape drive:
    File number=-1, block number=-1, partition=0.
    Tape block size 0 bytes. Density code 0x0 (default).
    Soft error count since last status=0
    General status bits on (10000):
      IM_REP_EN

    I understand this to mean that things look ok. Maybe I'm wrong?
    So, I issue the command to rewind and I get the following error:

    # mt -f /dev/nst0 rewind
    /dev/nst0: Input/output error
    mt: The device is offline (not powered on, no tape ?).

    But the device is on and I do have a tape in there.
    Any ideas? Or what other information can I provide to help tackle this
    problem?
