Unable to mount DVD - Ubuntu 14.04

Question

I seldom use the DVD drive and this a 5 year old laptop. Today I load the DVD and it just keeps spinning but nothing mounts. After it spins and stops I checked:

dmesg | grep sr0

[ 1.738204] sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray [ 1.738551] sr 1:0:0:0: Attached scsi CD-ROM sr0

I tried to manually mount with

sudo mount /dev/sr0

sudo mount /dev/cdrom

Then I checked:

mount | grep "/dev/sr"

It shows nothing.

The DVD is good and readable on my Windows machine.

Any ideas on how I can get it working?

Solution 1

I also couldn't mount movie DVDs, and was having this error:

~$ dmesg | grep sr0
VFS: busy inodes on changed media or resized disk sr0

The solution that worked for me was to edit /etc/fstab which I found in a mail-thread.

So, as described there, I edited the file, adding in the end the following line:

/dev/sr0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

and then I had to restart, since fstab is loaded on system start.

Solution 2

Did you get any message after mount /dev/sr0 or mount /dev/cdrom?

I got something like: mount: can't find /dev/sr0 in /etc/fstab or /etc/mtab

Here is a quick example on my Ubuntu 14.04 Desktop. I mount the DVD to /mnt

$ sudo mount /dev/cdrom /mnt/
mount: block device /dev/sr0 is write-protected, mounting read-only
$ cd /mnt/
$ ls
autorun.inf  casper  EFI      isolinux    pics  preseed             ubuntu
boot         dists   install  md5sum.txt  pool  README.diskdefines  wubi.exe'

Did you run mount /dev/sr0 /mnt/cdrom ?

[Ruslan Gerasimov]

Is it a DVD movie film or just data media? Are other disks mounted well in your system?

[John]

Its just data that I had backed up from the same laptop. I have just an internal HDD which is mounted and working.

Commands that you mentioned "sudo mount /dev/sr0" do not seem good for me until they have a place where to mount to. So what about running mount /dev/sr0 /mnt/?

[John]

sudo mount /dev/sr0 /mnt/ returns mount: no medium found on /dev/sr0

[John]

Yes, I also got the same message and I have already tried to manually mount to mnt. But when I try that I get mount: no medium found on /dev/sr0 OR mount: /dev/sr0 already mounted or /mnt/ busy Mostly it is the first message.

Can you try some other DVDs/CDs? Jsut want to make sure it's not a disk compatibility issue.

[John]

Same with every DVD that I try

the mount points (/media/cdrom nodes must exist and an appropriate line in the fstab file otherwise the user cannot mount them
