The “Transfer byte length” field in the CDB specifies the defect data length (number of bytes) that can be received by the INIT. The IDD terminates data transfer when transfer of the length of defect data specified in the “Transfer byte length” field is completed or when transfer of all the defect data of the specified type is completed. Also, when zero is specified in the “Transfer byte length” field, this command is terminated without execution of data transfer.

Figure 3.17 shows the format of defect data transferred to the INIT by this command.

a.P List (primary list) bit

When this bit is “1,” it indicates that P List defect data are included in the defect descriptor list that is actually transferred to the INIT. When it is “0,” it indicates that the P List defect data are not included. See 3) of item (2).)
