4.6 Packet Commands

The READ DEFECT DATA command transfers media defect data to the host.

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

The defect list format supported is listed in Table 4.90. If any other format is specified, the command assumes 101b and reports Recovered Error.
