Defective DAT drive or D-bus problem?

Show all headers | View raw

I installed an old and long unused WangDAT 3100 drive in a Debian Etch
box by means of an Adaptec 2906 SCSI-PCI adapter card.

$ hwinfo --tape
process 7998: arguments to dbus_move_error() were incorrect, assertion
        "(dest) == NULL || !dbus_error_is_set ((dest))" failed in
        file ../../dbus/dbus-errors.c line 282. This is normally a bug
        in some application using the D-Bus library. libhal.c 3483 :
        Error unsubscribing to signals, error=The name
        org.freedesktop.Hal was not provided by any .service files

  Config Status: cfg=new, avail=yes, need=no, active=unknown
  Attached to: #31 (SCSI storage controller)

I do:

$ mt -f /dev/st0 stat
drive type = 114
drive status = 318767616
sense key error = 0
residue count = 0
residue count = 0
file number = -1
block number = -1

$ mt -f /st0 status | grep error
sense key error = 0

Question is whether the problem is hardware related. Is $ hwinfo saying
the problem is with the D-bus rather than hardware?

$ tar -tvf /dev/st0
tar: /dev/st0: Cannot read: Input/output error
tar: At beginning of tape, quitting now
tar: Error is not recoverable: exiting now

$ mt -f /dev/st0 rewind
# mt ibs=64k obs=64k if=/dev/st0 of=/home/haines/working/test/test
