    from this source

    1. get the path of your DVD with blkid

      #example:
blkid
/dev/sda1: UUID="4ea68146-163e-4ce6-aeda-4cc2d338c2ed" TYPE="ext4" 
/dev/sdb1: UUID="e1977a53-b9f4-4c96-9251-84af259d06b4" TYPE="swap" 
/dev/sdb5: UUID="a85b1b95-c5ce-4557-9ca4-503b1a9ddcc8" TYPE="ext4" 
/dev/sdb6: UUID="c71a7601-04b8-4808-8f7b-ec967ac967ba" TYPE="ext4" 
/dev/sr0: LABEL="Disc" TYPE="udf"

      sdaand sdbare Hard Disk. /dev/sr0 is the DVD

    1. then to acces the DVD content, use foremost
      (Install it with sudo apt-get install foremost)

      List the content of the DVD (even the erased one):

      sudo foremost -w /dev/sr0
Processing: /dev/sr0
