25.1. Command Description

The REWIND command requests the Drive to rewind the tape
to the beginning of the current partition.
Prior to the execution of the rewind operation, the
Drive will write any buffered data that is to be written
to the tape. If
terminated with CHECK CONDITION and the Drive is in
buffered mode, then the Drive will discard any buffered
data when a REWIND command has been validated. When
using SLRtape140 to SLRtape7 or SLR32 media, the media
header is updated when the tape has been rewound to BOT.
If disconnection is allowed, the Drive will disconnect
when executing this command.
