Can't mount dvd on Linux

[rperegrin]

Hi,

I'm trying to mount an empty DVD in a SUSE 10 but I keep getting "No medium found." Please help me resolve this problem.

ngnqosa:/dev> cd /
ngnqosa:/> mkdir dvd
ngnqosa:/> mount -a /dev/dvd /dvd
mount: No medium found
ngnqosa:/>


Regards,

Robert

You don't mount the DVD, you mount a file system. An empty DVD has no filesystem to be mounted.

Various desktop environments such as GNOME or KDE will notify you of an empty DVD being detected, or put an icon on the desktop, but it isn't "mounted".

Are you having problems burning the DVD?

Hi Robert.

As mentioned above, you need to have a filesystem on the DVD in order to mount it --- so you can't mount an empty DVD, but you can mount say, a Linux distribution, or a data disk full of photos or MP3s or whatever.

I imagine you were trying to mount the DVD in order to write to it, yes? You don't need to mount a blank DVD in order to place files on it: simply use one of the DVD burning packages available for your distribution. A filesystem will be generated and written to the DVD in the burning process. You can then mount your DVD with something like

mount -t auto /dev/dvd /dvd

(Note that you don't need the -a switch unless you want to mount the filesystems in /etc/fstab as well.)

Hope that helps.

Hi Guys,

Yes, I was trying to burn a backup config file to a blank DVD. I tried your suggestion but got the below message.


mount -t auto /dev/dvd /dvd
mount: block device /dev/dvd is write-protected, mounting read-only
Note that /dvd is an existing folder and dvd is found on /dev.


Regards,

Robert

The message you got simply tells you that the filesystem is mounted read-only. This is normal. CDs and DVDs are not like hard drive partitions, floppy disks or USB sticks, where you can mount the filesystem on the media and then add files to it --- files are added to CDs & DVDs when they are unmounted. They are mounted only in order to read the data (hence the read-only message). Sounds a bit weird, I know, but that's the way they work! (If you want to stop the system telling you it is mounting the volume read-only, then including the -r option will instruct Linux to mount the filesystem read-only and hence avoid the read-only warning --- take a look at the manual page for the mount command if you want to know more on it.)

Anyway, it sounds as though there's now a filesystem on your DVD: try

mount -r -t auto /dev/dvd /dvd

as before and then

ls /dvd

...and see what it says.

Hello all,

Total noob here. Just thought I should warn you.

I am having a similar problem. I connected a USB DVD/CD device to my Suse server. I tried mounting it as stated above, but when I ran the command

mount -r -t auto /dev/sr0 /media/dvd

I received the message

mount: No medium found.


I have a data DVD in the drive. What am I doing wrong?
