I've wanted to make ISO images of some of my games so i can store the actual disks away and keep them safe. My program of choice is Alcohol 120%, and i had no problems using it but alas, the trial period is over and i dont have $50 handy to buy it. I decided to try a program called UltraISO to create an ISO image of my starcraft CD, but it ended up taking 3+ hours, with still over an hour remaining. Theres no way this could be right. I tried it again and the program stopped responding after it had been working for a while.

what could cause this? I've tried reinstalling the software, and im running win98.
