Hi,
after re-reading this diagnosis of the problem by the
author of growisofs
http://lists.debian.org/cdwrite/2008/07/msg00092.html
i developed a theory.
For details see
http://lists.alioth.debian.org/pipermail/debburn-devel/2013-June/000924.html
I do not want to use up a blank BD-R for growisofs experiments
(selfish as i am).
So the open question is whether this tiny patch prevents the
inappropriate attempt to execute that CLOSE SESSION command:
--- growisofs_mmc_orig.cpp 2013-06-14 19:53:51.000000000 +0200
+++ growisofs_mmc.cpp 2013-06-14 19:55:25.000000000 +0200
@@ -756,6 +756,8 @@ static void bd_r_format (Scsi_Command &c
wait_for_unit (cmd);
+ bdr_plus_pow = 1;
+
cmd[0] = 0x35; // FLUSH CACHE
cmd[9] = 0;
cmd.transport();
Maybe some Ubuntu expert can convert the patch into an end-user-ready
Ubuntu thingy and maybe some end-user is willing to give it a try
when the next BD-R is about to be written.
Have a nice day :)

Title:
Close session failed when burning 25gb blu-ray disc
Status in “dvd+rw-tools” package in Ubuntu:
New
Bug description:
I create an image burn and then try to use growisofs to burn it to a
25GB blu-ray recordable disc using Ubuntu 13.04 (64-bit).
rick@rick-CT14:~/Downloads$ lsb_release -rd
Description: Ubuntu Raring Ringtail (development branch)
Release: 13.04
rick@rick-CT14:~/Downloads$ apt-cache policy growisofs
growisofs:
Installed: 7.1-10build1

I expected to burn a blu-ray 25GB disc without error messages and
without corrupted files. I get a "close session failed" error message
with posssibly corrupted files. Even if the files aren't corrupted, it
is disconcerting.
I followed the procedure outlined by Steve Litt:
http://www.troubleshooters.com/linux/blu-ray-backup.htm
# Create empty file
truncate --size=24GB mybr2.udf
# Create udf file system
mkudffs mybr2.udf
# Mount file system
sudo mount -oloop,rw mybr2.udf /mnt/test
# Change ownership
sudo chown rick.rick /mnt/test
# Copy files into the mounted file system
# Unmount file system
sudo umount /dev/loop1
Everything above works as expected without problems.
# Burn to blank blu ray (25GB) empty disc
growisofs -speed=4 -Z /dev/sr0=mybr2.udf

The resulting blu-ray disc has the same total number of bytes as the
file system. I haven't found any bad files on the disc. I've tried
using k3b which "sort of" works but also has problems closing the disc
(and in some cases some files are corrupted or bad). I've used the
demo version of Nero for Linux on the same system - it creates a blu-
ray disc without reporting any errors or problems. I'd rather not have
to depend on proprietary software.
