I think we need more information.
having trouble copying files to a CD from my laptop.
What kind of CD? is it blank? Multi-session? are you using packet writing software or are you trying to burn it using a image burner?
Ony able to copy a few files when I should be able to copy much more
And you get what error when you try to copy "much more"? How much ARE you able to copy?
and sometimes the CD comes out a little scratched.
After burning? Is it only discs you burn? are you sure they weren't scratched already? do discs you read come out "scratched"?
