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.
