Problem with copying a simple disc

Sometimes when I begin to burn an image file of a non-protected original cd, (with Alcohol 120%) I get an error message saying something similar to: it cannot read a part of the disc, or internal read error, and the image making aborts and then I get a text box saying asking me if I want to erase the files that were copies before it all stopped.

What do I do, I’m sort of sure that it may be a scratched or damaged cd. (the original cd)

But I just want to make sure 100%…


Sounds like a scratch try cleaning the disc with soft cloth and check back of disc for scratches
