Writing to BD-RE and BD-R

Mac OS X

newfs_udf

You can create an UDF 2.50 formatted disc with Mac OS and write files to it with Finder, cp or other tools.

usage:

where rdisk2 is your BD drive

newfs_udf -r 2.50 /dev/rdisk2 -v BDUDF

to prevent the super-clever Mac OS from writing useless crap to your disc, execute the following commands:
(su is required to remove .Trashes)

where BDUDF is your Blu-ray Disc/Volume

sudo su
cd /Volumes/BDUDF
touch .fseventsd/no_log
rm .fseventsd/fseventsd-uuid
rm -fR .Spotlight-V100
touch .Spotlight-V100
rm -fR .Trashes
touch .Trashes

warning:

Writing (large) files to your BD can damage the UDF file system, which results in input/output errors, a crashing Disk Utility and kernel panics.

Toast 11 Titanium

Toast 11 is capable of writing Blu-ray Discs (without the High-Def/Blu-ray Disc Plug-in).

Dynamic Writing is quite useless as it creates an UDF 2.01 formatted disc.

Windows

Windows Explorer (Windows 7)

right click on BD drive, select format and UDF 2.50 for file system
