The point of using a program like EAC or DBPoweramp is that, if you choose, error won’t be accepted. If the disc can be read, a perfect copy will be made. If it can’t be read, a copy will only result if you’ve chosen settings which allow errors, hence allowing one to be made.
My own experience, with a thousand CDs or so, indicate that CDs which cannot be copied perfectly are very few and very far between. Off hand I believe I remember having trouble with 3.
