Multisession data DVD incorrectly identified as blank

Postby Kevin1 » 2018-07-08 19:26

Running Jessie 8.11, 3.16.0-6-amd64.
For several years I have been periodically archiving encrypted backups of my documents folder to Verbatim DVD+RW discs.

I format a new disc using:
Code: Select all
dvd+rw-format -force /dev/sr0


I add the first backup file to the disc using:
Code: Select all
growisofs -Z /dev/sr0 -V "VolumeLabel" -R -J /path/to/file


I add subsequent backup files to the disc using:
Code: Select all
growisofs -M /dev/sr0 -R -J /path/to/file


Until recently, on inserting a disc containing backup data, the disc volume label has been displayed in Nautilus and I have been able to access the backup files. Now, Nautilus identifies the disc as 'Blank DVD+RW disc'.

This occurs when I insert any of my many backup disks.
I can play video DVDs and audio CDs without problems, so I think the disc drive must be OK.
On another machine running Wheezy 7.11, 3.2.0-6-686-pae, all of the backup disks are correctly identified and accessed by Nautilus.

I suspect that a recent update to 64 bit Jessie has caused the problem.

Any advice, please?

I'd try a live-CD of Stretch to see if that works. If so, upgrade your system. A lot of bugs seem to have been worked out of Stretch.
