How to mount UDF DVDs in Ubuntu May 2, 2007Posted by amazingrando in Linux Tips, Windows-Linux Transition.
I’ve been mighty ill recently, so it’s been a while since my last post, but I finally seem to be recovering and it’s time for another post.
Traditionally recordable DVDs or CDs were written with the ISO 9660 file system. This made it work with everything from Linux to Windows to your car’s MP3 player. When DVD movies came out they used a new file system called Universal Disc Format or UDF, which is meant to replace ISO 9660. Ten years later people are still using ISO 9660 most of the time. But, that is changing. One of the biggest reasons for this is that ISO 9660 cannot handle files larger than 4GB. If you want to back up anything bigger than that you either need to split it (which can be a pain to split and recombine later) or you need to go with the UDF file system. I often backup files bigger than 4GB, so I pretty much only use UDF on discs I burn.
Ubuntu (and maybe other Linux distros – Debian?) seem to have a problem mounting UDF formatted discs. The solution to this is as simple as editing your /etc/fstab file and restarting. Here are the steps, from the Terminal:
sudo gedit /etc/fstab
Here you should see a line similar to this:
/dev/scd1 /media/cdrom0 udf,iso9660 user,noauto 0 0
The first part (/dev/scd1) is the device name (could be different with your computer), the second part (/media/cdrom0) is the mount point (where you access the disc in the file system). The third part is the file systems supported. This is where the problem lies. It shows UDF and ISO 9660, but if both are there (which is supposedly ok if comma-separated), then one or the other will not work, depending on the order they are written in the line. So the solution is the change both of those to:
Now the edited line will look something like:
/dev/scd1 /media/cdrom0 auto user,noauto 0 0
Now save the file and restart.
When you restart, UDF and ISO DVDs should work just fine!
