Hi thanks for the replies.
1. No I have no games that use Starforce nor have i ever heard of it :0
2. If it was a problem with the drive why would i work sometimes and not others?
3. The whole oc is only about 1 year old, so the drive itself is not that old.
4. Yes it's the only drive in my system never seen the need for more than 1.
I've seen other people mention this could be an issue to do with SecuROM that sometimes stops the drive detecting the disk but I have never had a game with this backward sort of protection before.
Surely it woul dbe easier to get owners of the game to register their cd key to an account to verify ownership that way. Then you just have to login to play, seems to work for many other games including mmo's.
