Length
This field specifies the length in bytes of all the block
descriptors. Since the media changer only allows one
block descriptor, the value must be either 0 or 8. A
value of 0 indicates no block description is included;
a value of 8 indicates a block descriptor is present and
precedes the mode page data. Any other value other
than 0 or 8 causes a CHECK CONDITION status with
sense key of ILLEGAL REQUEST to be returned.
