I couldn't find a tool to finalize (close) a BD-R
without writing any additional data. On Windows, ImgBurn has an option for it.
- wodim -fix only is suitable for CD and DVD.
- growisofs -dry-run can only be used before the data was written.
- xorriso -dev /dev/sr0 -speed -1 -close on doesn't seem to do anything, or perhaps I am not using it correctly.
