Field Name Description
Block This field specifies the length in bytes of all the block
Descriptor descriptors. Since the media changer only allows one
Length 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.
