The P (Primary) bit set to 1 specifies that the controller is to return the primary list
of defects. The P bit of 0 specifies that the controller must not return the primary
list of defects.
The G (Grown) bit set to 1 specifies that the controller is to return the grown list of
defects. The G bit of 0 specifies that the controller must not return the G list of
defects.
When both P and G bits are set to 1 simultaneously, the controller returns the P and
G lists in that order.
When both P and G bits are set to 0 simultaneously, the controller returns only the
defect list header.
The Allocation Length field specifies the number of bytes that the host computer has
allocated for returned Read Defect data. An allocation length of 0 specifies that no
Read Defect data is to be transferred.

The Read Defect data consists of a 4-byte header, followed by zero or more defect
descriptors.
