Figure 3.23 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.
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.
Note:
The Defect list length that can be specified for the IDD is 2,044 (X '7FC') bytes or less.
Therefore, a maximum of 511 defective blocks can be specified in the REASSIGN
BLOCKS command.
