Bit Field Values
•
Elements that can store media: StorDT, StorST
•
Valid Source->Destination pairs: ST->DT, DT->ST
All the "MT->XX" and the "XX->MT" entries are zero, since the loader will not accept
a Medium Transport element address as a source or destination.
All the "IE->XX" and the "XX->IE" entries are zero since there is no Import/Export
element.
Bytes 12 through 15 are all zero as the medium changer does not support the exchange
medium command.
