BD-R, BD-RE, DVD+RW, DVD-RAM and formatted DVD-RW are *always* appendable. You cannot finalize them.
Try burning to BD-RE or DVD+RW you've recorded with Nero with finalization. You'll be surprised

That seems a bit strange to me because I can use cdrecord to fixate the discs previously created with JStarBurn. After that action the discs' status is "complete".
When I create a BD with Nero and select "No Multisession" or "Multisession" with "Finalize"-option the disc's status is also "complete". I also get a "complete" disc when writing the disc with "dvd+rw-tools".
I need the finalization because I'm using the discs for archiving medical data and to comply with legal requirements it is necessary that the data on the discs can't be modified in any form.
