9 Prevent/Allow Medium
Removal—1Eh
Command Description
The
PREVENT/ALLOW MEDIUM REMOVAL
command determines whether the library permits the
removal of data cartridges. The library accepts this command, but does nothing in
response.
Note:
The library accepts this command, but does nothing. Because the
door to the library can be opened and the media removed, no
software method is available to prevent media from being removed
from the library. You may physically lock the library door with a key
to prevent media from being removed.
The table below shows the CDB for the
PREVENT/ALLOW MEDIUM REMOVAL
command.
The Prevent bit may be set to either 0 or 1. The library accepts both values, even
though the command has no effect.
