Hi,
My drive setup is returning an error on all BD-R media just at the very end
of the burn. [...] The media appears to be mountable and usable like the burn
completed normally.
System description is Ubuntu Linux12.04LTS with KDE desktop using K3b.
Probably you encounter a known bug of growisofs.
It is said to be harmless but lets K3b believe the burn run failed.
See:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=713016
Afaik, Fedora bothers to apply this fix in its packages.
Workaround is to format the BD-R before K3b hands it to growisofs
which would format it automatically, but forgets about this when
the burning is done:
dvd+rw-format /dev/sr0
That is what I suspected. I did attempt to format the BD-R last night.
No good. It would not attempt it. The program would run and then
terminate. I could format BD-RE OK. I located source code
dvd+rw-format.cpp and it indicated using -force option since BD-R can
only be formated once. Tried -force option (and others as well) and
still not working.
I have another machine with a blu-ray drive that is Slackware based. So
I attempted to format the media there. Still refused to do anything.
The compile date on the program was back in 2008 and that appears to
match the source code file I located. The program dvd+rw-mediainfo
reports the media is not formated after the attempt.
I was able to verify the BD-R media that was reported as an error. I
made recursive md5sum of all the source files and then used the file
across the media. All of the files reported OK. I did this on two of
the disks and that indicates the burn completed and all the files are
readable.
Thank you for the assistance,
James
