00h			NO SENSE: Indicates that there is no specific sense key information to be reported for
			the designated logical unit. This would be the case for a successful command or a
			command that received CHECK CONDITION or COMMAND TERMINATED status
			because one of the File-mark, EOM, or ILI bits is set to one. For File-mark or Set-mark
			detected the drive will be positioned on the EOM side of the mark if the drive direction
			was forward and on the BOM side of the mark if the direction was reverse.

			intervention may be required to correct this condition. Typically this indicates that there
			is no tape loaded. This status is also returned if the drive is currently rewinding
			following REWIND with Immediate bit set and another command is received (except
			for INQUIRY and READ BLOCK LIMITS which return GOOD status).
	04	00	LOGICAL UNIT NOT READY - Media is present within the drive.
			This status is returned to any tape motion command following UNLOAD with
			Immediate bit set or if the Eject button has been pressed by the operator. Also can be
			caused by the command sequence, PREVENT ALLOW MEDIA REMOVAL with
			Prevent bit set followed by UNLOAD. Tape motion commands such as READ, WRITE
			or SPACE are not allowed but Diagnostics which do not access the tape are permitted.
	04	01	LOGICAL UNIT IS IN PROCESS OF BECOMING READY - This status is returned
			following a LOAD command with the IMMED bit set for any tape motion command
			before the tape is loaded. Also during the auto load following a tape insertion.

			there is no media within the tape.
