Five different forms of the FORMAT UNIT command are supported through
different combinations of the Format Data bit, Complete List bit, and the information
in the Defect List Length field. (Refer to FORMAT UNIT Defect Header List for a
description of the Defect List Length field.) The different command forms give the
initiator control over the contents of the Grown Defect List. Table 5-13 describes the
contents of the Grown Defect List after FORMAT UNIT command execution.

The FORMAT UNIT Parameter List (Table 5-14) consists of a Defect List Header
(Table 5-15) followed by one or more Defect Descriptors. Descriptors are either four
bytes or eight bytes in length.
