Figure 3.16 REASSIGN BLOCK command: defect data list configuration
The “Defect data” list is configured from a 4-byte header and one or more defect descriptors which
follow it. One defect descriptor has a length of 4 bytes.
follow it. One defect descriptor has a length of 4 bytes.
The “Defect list length” field in the header indicates the total number of bytes (m) of the defect
descriptor list transferred after the header, and must be a multiple of 4. Also, when zero is
specified in this field, this command is terminated without transfer of the defect descriptor list and
allocation processing of alternate blocks.
