New here, and having trouble with megaman legends

[Kamen]

Hey all. I'm having trouble backing up my copy of megaman legends. I got it used, and it has the normal light use scratching on it, but no major scratches. I have tried Nero, CDRWin, and CloneCD, all of them fail. The problem seems to be with the 100+ meg .XA files under the XA folder. Is this a form of copy protection? I tried to copy a rental too (hopefully not illegal as I do own an original) but it is doing the same thing. Any info or advice would be much appreciated!
