Note 1) ddd: 0,0,0= D List in the block address format.
1,0,0= D List in the byte distance from the index format.
1,0,1= D List in the physical sector address format.
Note 2) The D List is not transferred from the INIT.
Note 3) If the data block length is changed and the disk media is initialized, the INIT cannot specify a
combination defect processing method.
Note 4) When this combination of defect processing methods is specified, the IDD performs
verification of the data blocks after initialization and creates the C List. In other combination
defect processing methods, the INIT can clearly specify whether the verification operation is
prohibited or permitted by the DCRT flag of the Format parameter.
