trouble mounting a DVD

English Install/Boot/Login
1

I burnt a tumbleweed DVD and it can be mounted on other systems (including other opensuse systems). I was able to install tumbleweed on the system in question and kept it up to date.

I can insert the same DVD and k3b recognizes it as a DVD iso and the only option is to copy DVD. When I boot from the DVD, it works. However, in the booted system, I cannot mount it as a file system, even as root.

mount -t auto /dev/dvdrw /mnt/3
mount: /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0: can’t read superblock

The DVD mounts on another system and the same DVD also boots correctly on this system so it does not appear to be a h/w issue or corrupt data. It seems to be some missing s/w or configuration on the current system that I cannot figure out.

Can someone point out what to look for ?

TIA.

You could at least provide the correct fs type at the mount

mount -t iso9660 ....

Maybe did not search good enough, but I can not find the -t auto in the man page.

Of course, I had also tried iso9660 and I got the following -

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.

I think that the DVD burner has gone bad. Another DVD drive works as expected in the same PC. Changed the IDE cable as well.
