The SuperLoader 3 uses the default address of 0. Defines the total number of medium transport elements contained in the media changer. Identifies the address of the first medium storage element contained in the media changer. Defines the total number of storage elements contained in the media changer. There are 16 total, although since the magazines are removable, eight of them may be "inaccessible" at times. Identifies the address of the first import/export element that is accessible both by the medium transport device and also by an operator from outside the media changer. [. . . ] Specifies the length in bytes of the Identifier that shall be transferred from the application client to the device server. The maximum value for this field shall be 64 bytes. A parameter list length of zero indicates that no data shall be transferred, and that subsequent REPORT DEVICE IDENTIFIER commands shall return an Identifier length of zero. If the parameter list length exceeds 64 bytes, then the drive will return CHECK CONDITION status with the sense key set to ILLEGAL REQUEST and an additional sense code of INVALID FIELD IN CDB. The SET DEVICE IDENTIFIER parameter list contains the identifier to be set by the addressed logical unit.
