Defect list
format
0 0 X X X
Default format . The initiator does not
send the defect list header or D-list to
the drive. The drive reallocates all
sectors in the P-list and erases the G-
list.
1 0 0 X X
Extended format. The initiator sends a
defect list header, but no D-list. Before
formatting, the reassigned LBAs are
merged into the grown defect list
(G-list). All sectors are then reallocated
using the P-list and the current G-list. At
the end of the format, the new G-list and
defect tables are stored on a reserved
area of the disc.
1 0 1 0 0
Format option with the G-list and D-list.
The initiator does not send a D-list to
the drive. The drive uses the existing G-
list to find defects and adds new defects
to the existing G-list in the bytes-from-
index format.
1 0 1 0 1
Format option with the G-list and D-list.
The initiator does not send a D-list to
the drive. The drive uses the existing G-
list to find defects and adds new defects
to the existing G-list in the physical
sector format.
1 1 0 X X
Format option without G-list or D-list is
selected, the initiator sends a defect list
header, but no D-list. The drive erases
any previous G-list.
1 1 1 0 0
Format option with D-list . The initiator
sends the defect list header followed by
a D-list in the bytes-from-index format.
The drive erases any previous G-list.
1 1 1 0 1
Format option with D-list and without G-
list
. The initiator sends a defect list
header followed by a D List of defects to
be reallocated. The D list is in the
physical sector format. Any previous G-
list is erased.
