Command Specifications

(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 Format" 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.

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 HDD does not apply sector interleave, but physically positions logical data blocks continuously in continuous sectors.
