Other format types have their certification intensity controlled by
a pair of bits: CmpList and DCRT.
CmpList resides in CDB byte 1 as bit 3. DCRT resides in the payload byte 1
as bit 5. Both together should request a quick size change without lengthy
certification but maintaining the list of known defects.
(mmc5r03c.pdf 6.5, table 249, 6.5.3.2)
With DVD-RAM on my PHILIPS SPD3300L drive they prevent any format size
change though. The TSSTcorp SH-S203B works properly.
With BD-RE format 00h, the default is specified to be Quick Reformat,
and with 00h in general certification can only be disabled not enabled.
