A Disable Block Descriptors (DBD) bit of zero indicates that the target may return zero or more block
descriptors in the returned MODE SENSE data, at the target's discretion. A DBD bit of one specifies
that the target shall not return any block descriptors in the returned MODE SENSE data. The page
control (PC) field defines the type of mode parameter values to be returned in the mode pages. The
page code specifies which mode page to return.
