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. Defect List Format is ignored.
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 is ignored.
The interleaving is set to the internal default value even if a value is specified.
