With BD-RE there are three format types : 00h, 30h and 31h.
|

00h offers the default size format.

30h offers several sizes with defect management. Usually there are three

size to choose: #1: default size, #2: maximum spare area, #3: minimal spare.

31h offers a single size and disables defect management. This has the side

effect to speed up writing to nominal speed.

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.

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.
