I have just bought this game and wanted to make a backup copy of it. I am using alcohol 120% with the safedisk 2 option. I made a perfect backup of the original generals using this option but i can't do the expansion pack. I have heard that it also uses cd checks. I have read the sticky guide but still can't work it out (thank you whoever made cd-rw's)!!! Just wondering if any one has made a perfect backup and if they could let me know how they went about it.

Thanks.
