The READ DEFECT DATA (12) command transfers the defect data to the host.

When Plist is 1, the command transfers header and PDL. When Glist is 1, the command transfers header and SDL. When both Plist and Glist are 0, the command transfers the header. When both Plist and Glist are 1, the command transfers PDL and SDL. PDL and SDL are respectively arranged in an ascending order.

The defect list format supported is listed in Table 4.95, Defect List Format - READ DEFECT DATA (12). If any other format is specified, the command assumes 101b and reports Recovered Error.
