This command transfers the list described in the defect position information of the disk media (defect
data) to the INIT.
There are two types of defect data, the P List (primary defect list) and the G list (grown defect list). The P List
indicates the defect position information at the time the disk drive was shipped from the factory. On the other
hand, the G List shows the defect position information specified from the INIT by the REASSIGN BLOCKS
command or automatic alternate block allocation processing, or when executing the FORMAT UNIT
command, or defective data block positional information from alternate block allocation from Verify operation
after initialization.
The INIT can specify the defect data type transferred to the INIT by the "P List (primary list)" bit and "G
List (grown list)" bit in the CDB and can specify the defect data format by the "Defect List Format"
field.
