The disk media defect processing method implemented during
FORMAT UNIT command execution is specified by the CDB and
by header of the format parameters transferred from the INIT. By
specifying zero in the "Defect list length" field in the Format
parameter header, the INIT can specify the control flags related to
formatting processing without transferring the defect list (D List).
C141-C009
STPF (stop format): Default value: "1"
When the defect list (P List or G List) necessary for executing the defect
processing specified in this command, cannot be read from the disk
media, this bit indicates whether to continue ("0" is specified) or
terminate ("1" is specified) command processing, but in the IDD, this
bit's specification is disabled, and the specified value is disregarded.
When the necessary defect list cannot be read, this command is
terminated with a CHECK CONDITION status. The sense data at this
time indicate "MEDIUM ERROR [=3] / Primary defect list not found
[=1C-01]" or "MEDIUM ERROR [=3] / Defect list error in primary list
[=19-02]," if the P List cannot be read and "MEDIUM ERROR [=3] /
Grown defect list not found [=1C-02]" or "MEDIUM ERROR [=3] /
Defect list error in grown list [=19-03]," if the G List cannot be read.
Immed (Immediate)
"1": If "1" is specified in the Immed (immediate) bit, at the point when
the CDB's legality is confirmed, or at the point when transfer of the
defect list is completed, a "GOOD" status is reported.
"0": If "0" is specified in the Immed (immediate) bit, the specified
operation is executed and the status byte is reported at the point
when that operation is completed, then the command is terminated.
Defect list length
This field specifies the total number of bytes in the "Defect list"
transferred from the INIT following the header. The byte length of the
"Defect descriptor" which configures the defect list differs depending on
its format and the value specified by this field must be a multiple of 8
when the defect descriptor is in the byte distance from the index format
or the physical sector address format. When zero is specified in this
field, it indicates that the defect list is not transferred.
