Help with diablo2

I am trying to back up diablo2. Now i rip/burn and it works on all 3 cds, but when i go to play with the back ups, it says it can not find the cd, but the cd still went into autoplay. im thinking maybe safedisc, just wondering if anyone can help me. Thank you.

As far as I know is Diablo II protected with Securom II.
Try CloneCD with the 2 Subchannel data options enabled, then it should work!
