If your optical drive cannot read the media, there is no software that will change that.  You can try another optical drive.  I tend to have more success with older optical drives.

If you think you have been responsible and tried every non-destructive method to read the disk, you can try to address the scratches on your DVD by gently rubbing away the surface of the disk with something like "Brasso".  Less is more.  Try a little at a time and keep trying to read the disk.

Good Luck.

I'm trying to recover data from a badly scratched vcd.

In windows I tried to make an image with ImgBurn, it retries with errors, so
I could get to a good 80% but after some time the program hangs. I thought
to use a rescue dedicated program, here ddrescue comes into play!

Here what I did:

ddrescue -b 2048 /dev/sr0 /myImage.img /myLog.log

What happens is that in a few seconds the error size grows to 650 MB, then
it starts "splitting failed blocks" and the "time from last successful read"
just keeps growing forever, I let it run for many hours with no change
(other that in the time that keeps getting bigger and bigger).

Am I doing something wrong, some option missing or what does it mean?

Any help really appreciated,

thank you very much,

hue truc
