I just got new SATA hard drives. After getting everything set up, I've tried putting some of my games back on the computer. I successfully installed and ran Rise of Nations and Star Wars Battlefront. I was able to install Rainbow Six: Ravenshield and Command and Conquer: Generals, but I can't play them. I get an error message saying it can't find the cd-rom. I have successfully run these games in the past. I started having this problem with the old hard drives too, where I tried to run Rome: Total War. This game also installed but would not play. The only games that I seem to have problems with are ones that have more than one disc. I've got 2 dvd-rom drives One is a 16x dvd/cd-rw drive and the other is a 16x dvd/rw drive. Does anybody have any idea what's going on?
