COMPLETE
LIST
(Byte 1, Bit
3)
- Set to one indicates the data supplied is the
complete list
of
known initiator-specified or field replacement defects. Any previous initiator-
specified defect map or defect data is erased. This purges
any
previous initiator-specified defect list and
builds a new defect list, which includes the initiator-specified list and the factory defects. A
CMPLST
bit
of
zero indicates that the data supplied is in addition to existing defect data using the current
format.
DEF~CT
LIST
FORMAT
(Byte 1,
Bits
2-0) - Specifies additional information related to the
defect list.
See Table 5-14 for further infonnation. -
DATA
PATIERN
(Byte 2) - User data pattern to
be
written repetitively into each sector during
FORMAT UNIT command
(if
this option is enabled by the Fill Data Pattern bit in Page 39H
of
the
MODE
SELECT command).
INTERLEA
VE
FIELD
(Bytes 3-4) - Specifies the interleave factor. Any value specified in this
field by the initiator will
be
ignored by the ProDrive. The ProDrive uses a
1:
1 interleave.

*Since the OAT A OUT phase does not occur, there is no defect list header.
The defect list shown in Table 5-15 contains a four-byte header which may be folowed by defect descriptors.
The defect list length is
equal
to four times the number
of
defect descriptors; it specifies the total length
in
bytes
of
the defect descriptors that follow. Each defect descriptor for the logical block format specifies a
four-byte defect logical block address that contains the defect. The defect addresses must
be
in ascending
order. The defect list length may be zero.
