How to make a copy of the Harry Potter game?

[Netherbrowse]

I own the Harry Potter game (Dutch version) and would like to make a copy of the original CD-Rom for possible later 'disasters'.

When I just burn the whole CD, via a temp folder on the hard disk. I cannot play the game from the copy CD-Rom. The error: 'Insert Original CD' appears (or a similar message).

I am able to run unsafe disk and play the CD without CD Rom, but would like to make a 100% similar copy of the original CD-Rom which runs on its own.

Can anyone give me some advise?
