REWIND Command (01h)
4
The
REWIND
command directs the DLT-S4 tape drive to position the tape
at the beginning of the currently active partition, always Beginning of
Media (BOM). Before rewinding, the drive writes any data in the write
buffer to the tape medium and appends an End of Data marker.

Immed
Immediate. When set to 1, the drive first writes any
remaining buffered data to the tape medium and
adds an EOD marker. It then returns status to the
host
before
beginning the actual rewind operation.
When set to 0, the drive returns status
after
the
rewind has completed.
