The SCSI-2 specification includes two commands which allow a medium-changer to perform most of the work that this routine does by brute force. Unfortunately, a reliable implementation of these commands was unavailable at the time MRD V1.2 was written. A future version of the API may be able to make use of these routines to speed up a search. Unlike mrd_show(3mrd) this routine will open and close the robot at each iteration.
