Use case: use remaining space on disc if BD-R burn was interrupted.

How it would work: growisofs -Z would auto-detect the next writable address (NWA), then use genisoimage -C 0,[NWA] to write the new data starting at the next NWA. Without genisoimage -c 0,[NWA], the OS can not find the new superblock.

genisoimage -C 0,[NWA]
(with uppercase "C").

Currently, this has to be done manually:

genisoimage -C 0,[NWA]  [other options] -o tmp.iso [files and folders to add]
growisofs -use-the-force-luke=seek:[NWA] [other options] -Z /dev/sr0=tmp.iso

NWA is always in 2K (2048 byte) logical blocks. The NWA can be found using dvd+rw-mediainfo /dev/sr0 (or whichever device name is in use).

I haven't yet added the error text. It is:

:-[ WRITE@LBA=0h failed with SK=5h/INVALID ADDRESS FOR WRITE]: Invalid argument
:-( write failed: Invalid argument

"LBA=0h" means it is trying to write at the beginning, which, of course, is impossible on an SRM non-POW formatted BD-R.

By that, I mean it is impossible if a session already exists on the disc. Of course, it <em>is</em> possible on a blank BD-R SRM. Clarified for completeness.
