The copy protection SimCity uses is called Long Track.
The problem with this kind of protection is that if your drives are
used a lot and not exactly adjusted, they *may* have problems with
the long track, a track in which more information is stored than
normally (this is done by lowering the drive rotation speed, thus to
copy it, you need to change your hardware).
Now if your drives have problems reading it, the software thinks
this is a copy and does not start (or produces a guru).
I strongly suggest that software companies should no longer use this
kind of protection. It caused me problems already several times now.
