The source address specifies the location from which the cartridge is taken; the
destination address specifies the location to which the cartridge is moved. If the
changer is specified, an Illegal Request error is returned.
The following table shows the addresses of the various elements.

If the MOVE MEDIUM command is received and the source element is empty or the
destination element (if different from the source element) is full, the Autoloader
returns a Check Condition and an Illegal sense key.
The source and destination address can be the drive element (address 1) or a valid
cassette storage element. If the address specified is not assigned to a specific
element or the drive is not the source or destination, the Autoloader returns a Check
Condition and an Illegal Request sense key.
