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.
