b. Format parameter (page code = 3)
Specify the number of spare sectors for each cylinder in the "alternate sectors/zone" field and
specify the number of tracks for alternate cylinders (= number of alternate cylinders
×
number
of disk drive heads) in the "alternate tracks/zone" field. It is recommended not to specify
values smaller than the IDD default value in this field.
(2)
FORMAT UNIT command
Initialize all sides of the disk with the FORMAT UNIT command. The FORMAT UNIT
command initializes all sides 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.
