trying to recover files from DVD


I'm trying to recover some files from a DVD RAM disk. The system is telling me there is nothing on the disk but when I look at the disk it is clear that there is data on it.

I am using Ubuntu 8.04 I have gotten as far as using dvdisaster to try and recover it. When dvdisaster finishes I am left with a file called "image.iso". When I try to read this file nothing seams to be able to read it. All the apps I have tried say it is not recognized as an ISO.

My question is what can I use to get the information back?

How do I go about doing this?

I have done a bit of googleing but nothing has helped yet....maybe I am not asking the right question.

I know of a couple of Windows apps that would do the job but BadCopyPro and ISO Buster. Any thing similar under Linux?

Any help would be greatly appreciated.

So what apps have you tried? Have you tried to mount it using the file loopback device? (must be 'root'):

mount -t iso9660 -o loop your_image.iso /mnt

ls /mnt

This is my terminal out put after sudo mount -t iso9660 /home/gabe/medium.iso /mnt

mount: /home/gabe/medium.iso is not a block device (maybe try `-o loop'?)
gabe@gabe-laptop:~$ sudo mount -t iso9660 -o loop /home/gabe/medium.iso /mnt
sudo: unable to resolve host gabe-laptop
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Not sure what all this menans??

What types of files are you trying to recover? You may have better luck using other tools directly on the raw device. What sort of damage has the DVD suffered?

I am trying to recover video word and jpeg files. I got most of the stuff back using "photorec". It would be better to get eery thing back but I am happy enough with the current out come....much better than nothing at all but the .doc files are unusable for some reason. I will continue to try different things to do a full recovery.

The disk is not damaged as such...it was accidentally deleted. This is why the system shows it as empty or not at all.

"You may have better luck using other tools directly on the raw device." can you elaborate on this for me a little, I'm not sure what you mean.
