Problems backing up ATV Offroad Fury

I recently tried backing up my copy of ATV Offroad Fury to test out my new ModChip. By the way my USB ModChip is working great! Well back on track when I popped ATV offroad fury to make an image of it on my PC with CDRWIN. I get at error trying to read it. so I can't get a back of my game. I noticed that on the game it has the DVD ROM symbol don't know if that means anything but I have seen others with it like Kessen but this is my first time running in to this problem Does anyone have information is the disc made different also the bottom of the CD is silver like a DVD not like the rest of the dark purple bottom of other PSX games. Any information will be great. Thanks.
