PC games backup

I have just tried to back up three oldish games that require the dvd to be in the drive whilst playing. I used “clone” and the process finished ok but the games wont accept the new copies as valid disks, even though on auto play the disks give me the original options to install etc.

Are games a problem for DVDFab? One of the games is 10 years old.

Somewhere there are threads about this, think maybe the box has to be chipped or something, also is it xbox 360 or what ?

As the thread title says, these are PC games not console games.

I just found some threads on this. Looks like the DVDFab clone is not quite a clone.
