Repairing a damaged DVD-R
 

I recently managed to damage a DVD-R accidentally when the underside of it was scored by something metallic as I was clumsily handling it.

Now it cannot be read on my computer.

Basically there is a long score mark that runs across the DVD nearly the entire diameter. I'm not sure how deep it is, but it doesn't appear to have gone to the media layer, I would hope.

I'm wondering what way there is to render it readable again. Is there a do-it-yourself method or some device/product? And if it is a product, what is the best reasonably price off-the-shelf one that can do the job?

Sure. There are buffing kits, polishing kits (manual and automatic crank), and software like Isopuzzle, which only works if you can at least get it to adknowledge that a DVD is inserted iirc. You probably won't get a full recovery, but you might get a big chunk back. Or maybe nothing, damage that bad is tough to recover from.

or try BadCopy Pro 3.8,you can recover any data from dc or dvd or HDD
