How can i make sure my cd is a faulty one?

Ok - i have emporer: battle for dune - is this 'copy' an original?
and from memory, only the first disc is protected - but there is no haze on any of the 4 discs, just a protection scheme on the first - im not quite sure on that though.
and the best advice would be to get your hands on an original copy of Red Alert 2 and see if your cd drive can read it. if it cant, (it uses the same protection) then i would reccomend investing in a new drive, becuase a lot of games coming out have the same protection scheme. if you can read and play red alert 2, then i'd ##### it in a friends/store's computer. if they work, theyres no way out - buy a cd writer or buy a new cd rom!
