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.

Table 4.103 lists the format of defect data transferred to the INIT by this

command.
