3.4.4.1 Types of defects
The categories of flawed sectors are described below. This defect list is
controlled by byte 1 of the defect list header described in Section 3.4.4.3.
•
When the drive is manufactured, the primary defect list (P-list) is
written to the disc in an area that is not directly accessible by the user.
This list of permanent defects (sometimes called the ETF list) cannot
be changed.
•
The data defect list (D-list) is a list of sectors supplied to the drive by
the initiator during a data-out phase of the current Format Unit
command. The drive sends the D-list in the last bytes of the defect list
described in Section 3.4.4.3.
•
The
grown defect list (G-list) is a list of sectors that contain media
flaws. The drive reallocated these sectors during the last Reassign
Blocks command, or they are data defects (D-list) reallocated during
a previous Format Unit command, or they are defects that have been
automatically reallocated by the drive. This G-list is recorded on the
disc and can be referenced by current and subsequent Format Unit
commands. The G-list does not include P-list defects.
•
The certification defect (C-list) is a list of sectors that were incorrectly
formatted by the drive during the Format Unit command. This list is
created when the DCRT bit of the defect list header is set to zero.
3.4.4.2 Format Unit parameters
For each format listed below, except the default format, the initiator sends
a defect list header. This header is described in Section 3.4.4.3. The
bytes-from-index format is described in Section 3.4.4.4 and the physical
sector format is described in Section 3.4.4.5. The block format is not
discussed.
