That's all because cdrecord does not automatically format
BD-R before writing. (Neither do libburn based programs
like xfburn, cdrskin, or xorriso.)

You can achieve the same effect with growisofs by option
  -use-the-force-luke=spare:none

In previous versions of K3B there was a menu to set
options for backend programs ... "Setup External Programs",
"User Parameters".

Ah no. I am a competitor of growisofs, but would not say
that. Actually growisofs has more clue about the MMC
aspects of BD media than cdrecord.

It's just that Andy wanted to be smart with auto-formatting
and regrettably quit maintaining of growisofs before he
could iron out the consequential bugs.


Have a nice day :)
