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.
