Default Format: No Data Out phase occurs. disc drive reallocates all
sectors in the P list plus any sector which fails the Format Verify phase
(C type flaws). Any previous G list is erased.

(Not supported by Seagate drives) Format with G and no D: A four byte
Defect List Header must be sent by the initiator. No Defect Descriptors
(D list) are sent by the initiator. The disc drive reallocates all sectors in
the drives current G list. See also note [2].

Header followed by a D List of defects for disc drive to reallocate. The D
list must be in the Physical Sector format (see Table 5.2.1-6f). The disc
drive also reallocates all sectors in the drives current G list. See also
note [2].
[1] Refer to Table 5.2.1-3.
[2] Byte one of the Defect List Header determines whether the P and C defects are
reallocated. See Table 5.2.1-5b.
