Disc Read Error Issue

Only sometimes when Iā€™m copying a game, (not all the time) I receive sometimes a few and sometimes hundreds if disc read error messages, but the games still keeps copying. Does that mean that there is something wrong with the original CD or it that just a part of the protection?

Afterwards the copied Disc seems to work fine. :confused:

The read errors are just part of the protection so just let it go all is fine
