I am trying to burn a copy protected CD for my course work. I was able to save the whole content in a .iso image file using IsoBuster and burn it using Nero. But when I try to run the copied CD, it says original copy is required and stops there.

Do you know any clonning program that helps me to produce usable copy?

Any good suggestion is highly appreciated.

I tried CloneCD. It didn't work either. Any expert out there?

Try Alcohol 120% http://www.alcohol-soft.com/

Thank you Ramchandre for your suggestion. Concentrated alcohol also could not clean the protection. I used Aray to find the datatype but it could not do the job. Looks like most of these softwares are game cracker but not this type of CD cracker.

Any expert?

Try Everclear 90%.
