Erreurs de montage en essayant d'ouvrir un DVD - l'unité est-elle en panne?

J'utilise Ubuntu 14.04. Lorsque j'ouvre un DVD particulier dans Nautilus, j'obtiens cette erreur.

    Error mounting /dev/sr0 at /media/user/L'ECO DEL SILENZIO: Command-line `mount -t "udf" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,umask=0077" "/dev/sr0" "/media/user/L'ECO DEL SILENZIO"' exited with non-zero exit status 32: mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

J'ai essayé d'identifier le problème:

Sudo -H gedit /etc/hdparm.conf

ajouter en bas

/dev/sr0 {
    dma = on
}

redémarrer
