94 Commands
PREVENT/ALLOW MEDIUM REMOVAL 1Eh
PREVENT / ALLOW MEDIUM REMOVAL tells the drive to enable or disable the
removal of the cartridge.
When cartridge removal is prevented, the front panel eject button is completely
disabled (though a ‘forced eject’ will still work). An Unload command issued
by a host will result in CHECK CONDITION . The sense key will be ILLEGAL
REQUEST or MEDIUM REMOVAL PREVENTED .
When cartridge removal is enabled, pressing the front panel eject button or
sending an Unload command from a host will cause the media to be unloaded
and ejected.
Removal prevention is on a per-host basis. All the hosts have to allow media
removal for any of them to do so.
Note If a firmware upgrade is initiated over any interface, the
cartridge will be ejected from the drive regardless of the state of
this command.
