5.21 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.

Immed 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.
