This is probably the known CLOSE TRACK/SESSION bug at the end of a growisofs BD-R burn which started on a blank BD-R medium. It was diagnosed by Andy Polykov five years ago http://lists.debian.org/cdwrite/2008/07/msg00092.html "Trouble is that when growisofs pre-formats the blank, it fails to instruct finalization procedure about it. [...] You might want to consider explicitly pre-formatting media with dvd+rw-format [...] " >From comparing the code which inspects the submitted medium and the code that formats a blank BD-R, i came to this patch: ---------------------------------------------------------------------- --- 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(); ---------------------------------------------------------------------- The patch was tested with success by Frank Griffin http://lists.alioth.debian.org/pipermail/debburn-devel/2013-June/000928.html Fedora has adopted it for testing and it seems to help https://bugzilla.redhat.com/show_bug.cgi?id=858029 https://bugzilla.redhat.com/show_bug.cgi?id=868527 Reasoning of mine why the patch should help (or at least not harm): http://lists.alioth.debian.org/pipermail/debburn-devel/2013-June/000924.html Have a nice day :) Thomas
