kill.switch problems

[sublime90]

ok i finally got a working copy of kill switch, i usually just copy on the fly but instead i created an image and it worked fine, but has anyone tried backin up medal of honor rising sun? i copied on the fly and its horrible it freezes so much and when i tried to create an image i get another extra file its weird. MOH:RS is 4.28 GB the image is only 3.99 plus another file labeled mohrs.nrg001 is 299 mb, i tried to just burn the image but it doesnt work i get an error so if anyone could help me make a working copy of rising sun much appreciated
