This command is not to be used by the low-level driver; rather, it is intended to
be used by applications, which usually have access to the drive only through the
ATAPI protocol.

LOAD (with or without Retension) is accepted any time a tape is present in the
drive, (even if status indicates it is already loaded). This command includes
implicit rewind and select partition 0 operations. The DSC bit is reset (0) after
this command is accepted and is set (1) when the drive has initialized and is
ready. REQUEST SENSE can then be used to verify successful command
completion.
The UNLOAD option(s) retensions the tape (if selected) and moves the tape to
the logical BOT or EOT end (as selected), then causes the drive to report not
ready to any subsequent media access commands. Either a manual load
operation or LOAD command is required for the drive to return to ready.
