b.Format parameter (page code = 3)
Specify the number of spare sectors for each cell in the "alternate sectors/zone" field. It is recommended not to specify values smaller than the IDD default value in this field.
(2)FORMAT UNIT command
Initialize all recording surface of the disk with the FORMAT UNIT command. The FORMAT UNIT command initializes all surface of the disk using the P lists, verifies data blocks after initialization, and allocates an alternate block for a defect block detected with verification. With initialization, the value "00" is written into all bytes of all logical data blocks. Only the position information of defect blocks detected with verification is registered in the G list. The specifications are as follows:
a.Specifying CDB
Specify 0 for the "FmtData" bit and the "CmpLst" bit on CDB, 000 for the "Defect List Format" field, and data pattern written into the data block at initialization for the "initializing data pattern" field.
b.Format parameter
When the values in step a. are specified with CDB, the format parameter is not needed.
