> Cdrecord will be changed to work-around the firmware bug Tested last night with cdrtools a77 version on sun ultra 60 with solaris 10 The work-around allowed me to burn a 7 GB image to blu-ray disc but it took over 2 hours, seemingly as slow as growisofs on that machine How do I get cdrecord to burn at 2x speed? # cdrecord -v dev=4,0,0 speed=2 driveropts=burnfree image.iso cdrecord: No write mode specified. cdrecord: Assuming -sao mode. cdrecord: If your drive does not accept -sao, try -tao. cdrecord: Future versions of cdrecord may have different drive dependent defaults.
