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)
"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.
"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.

Defect list length
This field specifies the total number of bytes in the "Defect list" transferred from the
INIT following the header.
configures the defect list differs depending on its format and the value specified by
this field must be a multiple of 4 when the defect descriptor is in the block address
format, and 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.
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).
b. Defect list (D List)
The defect list (D List) contains defect position information about the disk media specified
by the INIT and is configured from one or more "Defect descriptors." "Defect descriptors
must be described in the format specified in the "Defect List Format" field of the CDB.
The byte length of the "Defect descriptor" which
