Hi Katta-san,
I saw there was some apprication did check Blank bit with ReadTrack command 
when BD-RE un-formatted media install.
The apprication expected Blank bit =1 for formatting BD-RE disc which was
MMC-5 
Rev-1.
I would like to confirm current apprication has been implemented MMC-5 Rev-4
or 
later and there is no problem 
if drive return Blank bit =0 when BD-RE un-formatted media
inserted and can perform format.
Regards
