3.25.2 READ DEFECT DATA (12) parameter data
The READ DEFECT DATA (12) parameter data (see table 129) contains an eight byte header, followed by zero or more address descriptors.
See the READ DEFECT DATA (10) command (see 3.24.2) for the definitions of the fields in the defect list header that are not
described in this clause.
DEFECT LIST LENGTH field
The DEFECT LIST LENGTH field indicates the length in bytes of address descriptors from the beginning address descriptor
specified by the ADDRESS DESCRIPTOR INDEX field to the last address descriptor available to be returned. A value of FFFF_FFFFh
in the DEFECT LIST LENGTH field indicates that more than FFFF_FFFEh bytes are available.
