The Format Unit parameter list shall be transferred from the Host to the drive. The data sent to the drive consists of a Format List
Header, followed by one Format descriptor, so the parameter list length is always 12 bytes. When the Format Options Valid
(FOV) bit in the Format List Header is set to one, the DPRY, DCRT, STPF, IP, Try-out, and VS shall be set to zero. In this case,
the format operation is performed with an Immed function specified by the Immed bit. When the FOV bit is set to zero, the
DPRY, DCRT, STPF, IP, Try-out, Immed, and VS shall be set to zero. In this case, the format operation is performed with the
drive’s internal default setting. The default setting of Immed function is one. Even if the format operation is requested with the
FOV bit set to one, the drive’s default setting itself will not be changed.

4.3.1.1.1 On DVD-RAM media
The defect list handling is specified by the combination of the CmpLst bit and the DCRT bit. In the case that the CmpLst bit is
set to zero and the DCRT bit is set to one, the Number of Blocks field shall be ignored and the number of addressable blocks
shall be retained. In other cases, the Number of Blocks field specifies the number of addressable blocks for the whole disc and
the Type Dependent Parameter field specifies the Block Length. Neither field is changeable from the values reported by READ
FORMAT CAPACITIES command.
The defect list handling is decided by the following combinations.
