Field Name Description
Prevent When set to 1, removal via operator control is
disabled. A MOVE MEDIUM command with a
destination address equal to the mail slot would
return a CHECK CONDITION status. The sense key
shall be ILLEGAL REQUEST with the additional
sense code MEDIA REMOVAL PREVENTED. The
PREVENT/ALLOW status in the device is
maintained separately by each initiator.
When set to 0, the prevent state corresponding to that
initiator is cleared. By default, after power up, a hard
reset, or BUS DEVICE RESET message, the prevent
medium removal function is cleared.
