Byte 2 If the PList bit is 1, the drive sends the primary defect list. If
the PList bit is 0, the drive does not send the primary defect
list.
If the GList bit is 1, the drive sends the grown defect list. If
the GList bit is 0, the drive does not send the grown defect
list.
If both the PList and GList bits are zero, the drive returns
the defect list header only.
If the defect list format field contains 101
B,
the drive returns
the defect data in the physical sector format. If the defect
list format field contains 000
B
or 100
B,
the drive returns the
defect data in the default format, which is the physical sector
format, and generates a check condition status.
Bytes 7–8 The allocation length specifies the number of bytes the
initiator has allocated for the returned defect data;
this is
not an error. An allocation length of 0 indicates that no
defect data is transferred. The data-in phase ends when the
allocation length bytes have been transferred or when all
available defect data has been transferred to the initiator,
whichever is less.
