I haven't checked because I'm at work, but I believe you will have issues with your registry entries. If SH3 is listed in your registry, then you won't be able to run it. I would use Nortons Ghost then uninstall all unwanted programs from your new C drive. Reinstall any you wish to have on your new D drive. Also be careful about the windows/system partition size. Add at least half again as much as the Microsoft recommend size. This will give the system room to grow (which it will do). Hope this helps.
