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
