The "Transfer byte length" field in the CDB specifies the defect data length (number of bytes) that can be received by the INIT. The HDD 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.

Table 4.44 lists the format of defect data transferred to the INIT by this command.
