PREVENT/ALLOW MEDIUM REMOVAL1Eh

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.
