Me either. I had a commercial CD that I kept "pristine". When it wouldn't read correctly, I held it up to the light and could see pinpoint holes large enough for tiny shafts of light to come through. Using magnification the holes looked like corrosion had 'eaten' away the substrate material as if tiny moths or worms were inside the plastic. As I said, this disc was pristine, always in a case, no scratches, nothing except internal corrosion that destroyed it from inside itself. Probably not that common an occurrence, but what can you do when it happens?
I think this why the hacker community favors .rar files, because they're redundant and can regenerate missing or corrupted data if necessary. The downside is I think the regeneration process is very time consuming and CPU intensive.
