There is a better way...
Instead of using downloaded applications (which almost always come from sites that have adware/spyware/browser hijacking/virus) to crack your main exe, and copying the entire disk, you can use mini images. Mini images are files that are exact copies of your disk, except they are much smaller in size, and they only contain about the first few percent of the disk. Games just detect your disk by reading very little data off of it, so you don't need to copy the entire disk. There are many pre-made mini images (also called mini disks, mini iso's) available online. Search google. It is pretty damn easy to make your own, too. I never did it, but I read the instructions and it seemed simple. I don't have a link, but you can google that too. When you finally obtain a mini image of the game you want to play, you need Daemon tools. Daemon tools is a piece of software that tells your computer that you have a CD/DVD drive, and it emulates them. You mount (load) your mini image into Daemon tools, and when the game checks for the data, it finds it. The best part about this is that you don't need to match up any game versions, and even if you update your game, it will still work.
Google: Daemon tools, download it.
Google: 'your game' mini image.
