Bad sectors are very normal when copying a SafeDisc protected game. I just advised you to use ClonyXL to determine if it's protected with SafeDisc 1 or 2. If your game is protected with SafeDisc 2 you'll need compatible hardware to copy the game!
Please let me know.
Ps. If the game has the normal SafeDisc protection just enable the Fast Error Skip option in CloneCD and start reading. There are a few hundred errors in the first 10.500 sectors of the disc. After these first 10.500 sectors the game should be error free.
