[1] Byte 1 of the Defect List header determines whether the P and C defects are reallocated. See Table 98.
[2] See individual drive’s Product Manual, Volume 1, for support/non-support.
The defect list shown in Table 98 contains a four-byte header followed by one or more defect descriptors. The
Defect List Length in each table specifies the total length (in bytes) of the defect descriptors that follow. In Table
98 the Defect List Length is equal to eight times the number of defect descriptors.

0XXXX
Default format: No data is transferred. The disc drive reallocates all sectors
in the P list plus any sector which fails to Format Verify phase (C type
flaws). Any previous G list is erased.
Block format [2]
100XX
Format with G and no D: A four-byte Defect List header must be sent by the
initiator. No Defect Descriptors (D list) are sent by the initiator. The disc
drive reallocates all sectors in the drive’s current G list. See also note [1].
110XX
Format without G or D: A four-byte Defect List header must be sent by the
initiator. No D list may be sent by the initiator. The disc drive erases any pre-
vious G list. See also note [1].
Bytes from Index format
11100
Format with D and without G: The initiator must send a four-byte Defect List
header followed by a D list of the defects for the disc drive to reallocate. The
D list must be in the bytes from Index format (see Table 102). The disc drive
erases any previous G list. See also note [1].
10100
Format with D and with G: The initiator must send a four-byte Defect List
header followed by a D list of the defects for the disc drive to reallocate.
The D list must be in the bytes from Index format (see Table 102). The disc
drive also reallocates all sectors in the drive’s current G list. See also
note [1].
Physical Sector format
11101
Format with D and without G: The initiator must send a four-byte Defect List
header followed by a D list of defects for the disc drive to reallocate. The D
list must be in the Physical Sector format (see Table 103). The disc drive
erases any previous G list. See also note [1].
10101
Format with D and with G: The initiator must send a four-byte Defect List
header followed by a D list of defects for the disc drive to reallocate. The D
list must be in the Physical Sector format (see Table 103). The disc drive
also reallocates all sectors in the drive’s current G list. See also note [1].
