allocation length bytes have been transferred or when all
available defect data has been transferred to the initiator,
whichever is less.
3.5.7.1
Defect list header
The defect data always begins with a 4-byte header, followed by a 6-byte
descriptor for each defect. The defect list header format is described
below.

Defect list length
Byte 1
If the
P-list bit is 1, the defect data contains the primary
defect list. If the P-list bit is 0, the defect data does not
contain the primary defect list.
If the
G-list bit is 1, the defect data contains the grown defect
list. If the G-list bit is 0, the defect data does not contain the
grown defect list.
The
defect list format field is described in Section 3.5.7.
Bytes 2–3
The
defect list length specifies the length of the defect data.
If the P-list and G-list bits are 0, no defect descriptor bytes
are sent to the initiator and the defect list length is 0. If the
allocation length (in the CDB) is not large enough to accom-
modate all the defect descriptors, the defect list length
contains the same value as the allocation length.
