** Description changed: + [Impact] + * All users of growisofs (including users of frontends like k3b) get a spurious IO error at the end of writing a blue-ray BD-R medium + * The fix is very simple and just a single line, details in http://lists.alioth.debian.org/pipermail/debburn-devel/2013-June/000924.html + + [Test Case] + * you need a blue-ray BD-R medium and e.g. k3b + * create a data project with e.g. 22GB + * write using a blank BD-R + * observe a IO error at the end of the write (the disc is fine though) + + * install growisofs from -updates + * repeat the test and verify that there is no write error this time + * bonus points for checking "verify written data" in the burn dialog of k3b + + [Regression Potential] + * its already showing a IO error at the end, its unlikely that the patch makes it worse + + ------------ + 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 - Candidate: 7.1-10build1 - Version table: - *** 7.1-10build1 0 - 500 http://us.archive.ubuntu.com/ubuntu/ raring/main amd64 Packages - 100 /var/lib/dpkg/status + Installed: 7.1-10build1 + Candidate: 7.1-10build1 + Version table: + *** 7.1-10build1 0 + 500 http://us.archive.ubuntu.com/ubuntu/ raring/main amd64 Packages + 100 /var/lib/dpkg/status I expected to burn a blu-ray 25GB disc without error messages and without corrupted files.

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.
