3.3 Format Commands
C141-E167
3 - 77
(2) Specifying the initialization method
The INIT can specify the method of defect processing executed by this command in the “FmtData
(format data)” bit and “CmpLst (complete list)” bit of CDB byte 1 and the “Defect List Format”
field.
When “1” is specified in the “FmtData (format data) bit, it indicates that the format parameters
(header and defect list), described later, are transferred from the INIT when this command is
executed. When this bit’s specification is “0,” it indicates that the format parameters are not
transferred.
When the “CmpLst (complete list)” bit is “1”, it indicates that the previously existing G List is
replaced with the defect list (D List) transferred from the INIT when this command is executed.
When this bit is “0,” the contents of the D List are added to those of the previously existing G List.
The “Defect List Forma” field specifies the format of the defect list (D List) transferred from the
INIT when the “FmtData (format data)” bit is “1.” Any one of the following formats can be
specified for the defect list.
Defect List Format D List Format
0 0 0 Block Address Format
1 0 0 Byte Distance from the Index Format
1 0 1 Physical Sector Address Format
If (0,0,0) is specified in the Defect List Format field and a value other than 0 is specified in “Defect
List Length” in the Format parameters, this command is terminated with a CHECK CONDITION
status (ILLEGAL REQUEST / Invalid field in parameter list).
The “Interleave factor” field in the CDB specifies the method of positioning logical data blocks in
physical sectors on the disk media. Whichever value is specified in this field, the IDD does not
apply sector interleave, but physically positions logical data blocks continuously in continuous
sectors.
