I have bought an external DVD driver but, after plugging (or booting with the unit already plugged) I see the unit listed in the resources of the computer but I cannot access it:

enter image description here

If I try to access the driver via VLC, I get the error VLC is unable to open the MRL 'cdda:///dev/sr0'.

The content of fstab is:

$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/nvme0n1p2 during installation
UUID=341faa1b-4e49-49d7-85a4-e33acecb2212 /               ext4    errors=remount-ro 0       1
# /boot/efi was on /dev/nvme0n1p1 during installation
UUID=24D6-7429  /boot/efi       vfat    umask=0077      0       1
/swapfile                                 none            swap    sw              0       0

What is the right way to plug a DVD in Ubuntu 20.04? Is it a problem with the driver (I need to buy another brand more Linux-prone)? Or do I need to change the permission of the driver with some sudo commands?

After I plug the DVD driver I get:

$ ls -lt | less | grep sr0
lrwxrwxrwx  1 root   root           3 May 27 21:15 cdrom -> sr0
lrwxrwxrwx  1 root   root           3 May 27 21:15 cdrw -> sr0
lrwxrwxrwx  1 root   root           3 May 27 21:15 dvd -> sr0
lrwxrwxrwx  1 root   root           3 May 27 21:15 dvdrw -> sr0
brw-rw----+ 1 root   cdrom    11,   0 May 27 21:15 sr0

Thank you

  • Is there a disk in the drive? Have you tried putting one in? Does eject work?

Looks like your drive hasn't been mounted. Please follow the steps below:

  1. Fire up a terminal and type mkdir /media/cdrom.
  2. Then, type sudo mount -t auto /dev/cdrom /media/cdrom.
  3. See if it works; if not, reboot and check if you can access it.

This should work. If not, please leave a comment.

EDIT: please try the steps below.

  1. Open up a terminal and write cd /dev/.
  2. Then, ls -lt | less and see if you find dvd -> sr0 or cdrom -> sr0.

  • Thank you, I got the following: ``` $ sudo mkdir /media/cdrom $ sudo mount -t auto /dev/cdrom /media/cdrom mount: /media/cdrom: special device /dev/cdrom does not exist. # mounted devide $ sudo mount -t auto /dev/cdrom /media/cdrom mount: /media/cdrom: /dev/sr0 is not a valid block device. ``` Then same thing: device first detected (the folder of the drive was empty) then removed.

  • Please open /etc/fstab and post the content here (please add it as an edit to your original post).

  • Thank you. Please make a backup of your existing /etc/fstab to a location of your choice and then edit the non-backup by adding /dev/sr0 /media/ udf,iso9660 noauto,user,ro 0 0. Save and reboot.

  • Thanks but the problem persists. Would running a DVD need sr0 or something else? could be a brand problem? Perhaps some brands work out of the box...
