Not a problem
Its a good way to check the game isnt falty before you burn it on a disk.
Also another bit of info for you, im sure games no that you cant play games with back-up cd's unless they copied it witht he correct potection or they have a crack, but if you have a games image on your pc (example the .bin) and you mount it you can play it with out a crack or any thing, only bad thing to that is you need to spare 700mb free per game lol and more for dvd-roms!!
