Package: dvd+rw-tools
Version: 5.20.4.10.8-1
Severity: important

I am using growisofs to burn daily incremental backups, everything worked fine until recently, when my multissesion disk simply failed to mount with generic error message:

mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems

In other words up to certain momemt I was able to mount the disk, but after adding
yet another session I lost this ability.

The interesting bit is that disk still can be read on Windows box just fine. Mac will see
only first session, and few Debian boxes I tried simply refuse to mount it. So looks
like growisofs burns somewhat incomaptible disks.

I don't have log from burn session which caused the problem, but I am able to burn additional sessions, and get dvd+rw-media report -- both do not have any error messages. Could be that I exceeded some data dvd format limit? Like too be related to the problem.

Anyways here are some logs, note that problem started manifesting itself after session 9.
Sessions 10 and 11 are test sessions.
