Good idea, but sadly there is nothing useful there.  The following
happened during my tinkering with mt, tar, and dd:

Mar 19 14:06:32 atlas kernel: sa0 at ahc0 bus 0 target 6 lun 0
Mar 19 14:06:32 atlas kernel: sa0: <QUANTUM DLT-V4 0A00> Removable
Sequential Access SCSI-2 device
Mar 19 14:06:32 atlas kernel: sa0: 160.000MB/s transfers (80.000MHz,
offset 96, 16bit)
Mar 19 14:23:46 atlas kernel: (sa0:ahc0:0:6:0): Unexpected busfree in
Data-out phase
Mar 19 14:23:46 atlas kernel: SEQADDR == 0x86
Mar 19 14:23:46 atlas kernel: (sa0:ahc0:0:6:0): lost device
Mar 19 14:23:46 atlas kernel: (sa0:ahc0:0:6:0): failed to write
terminating filemark(s)
Mar 19 14:23:47 atlas kernel: (sa0:ahc0:0:6:0): tape is now frozen-
use an OFFLINE, REWIND or MTEOM command to clear this state.
Mar 19 14:23:47 atlas kernel: (sa0:ahc0:0:6:0): removing device entry
Mar 19 14:27:37 atlas kernel: sa0 at ahc0 bus 0 target 6 lun 0
