BD-R not getting finalized



Hi all,

 This is the second BD-R where growisofs fails during the last stage of
finalizing the disk
 I am using a USB external writer but I do not see any USB related
errors in the kernel.

 The end snippet is below


21458026496/21474836480 (99.9%) @1.3x, remaining 0:03 RBU  50.1% UBU  82.8%
builtin_dd: 10485760*2KB out @ average 1.2x4390KBps
/dev/sr1: flushing cache
/dev/sr1: closing track
/dev/sr1: closing session
:-[ CLOSE SESSION failed with SK=5h/INVALID FIELD IN CDB]: Input/output
error
/dev/sr1: reloading tray

I am not trying to rule out a possibility of error in the BD-R media but
2 in a row is something which makes me suspect factors other than the media

The media is a single layer Maxell BD-R (25G) and I am writing a file
iso 20GB long (mostly containing my backup data)
Has anyone come across this before ?
