The FORMAT UNIT command formats media physically on the basis of the specified parameter
values.
When the FmtData bit is 1, the FORMAT UNIT parameter list must be transferred. When the
FMtDAta bit is 1, the Defect List Format must be specified. Defect List Format can be 7 only.
When the FmtData bit is 0, the ODD does not transfer the FORMAT UNIT parameter list and
formats media using the internal default values instead.
The CmpList bit must be 0. If it is 1, the command responds with Check Condition.
The interleaving is set to the internal default value even if a value is specified.
