Rewind Command (01H) - Quantum DLT 8000 Product Manual

5.26 REWIND Command (01h)

The REWIND command directs the tape drive to position the tape at the beginning of
the currently active partition (for DLTtape drives, this is BOM). Before rewinding, the
tape drive writes any write data that is in the buffer to the tape medium and appends an
End of Data marker.

Operation Code (01h)
Description
Immediate. If this bit is set to 1, the tape drive first writes any
remaining buffered data to tape medium and adds an EOD marker. It
then returns status to the host before beginning the actual rewind
operation. If this bit is 0, status will be sent after the rewind has
completed.
