I am dual booting multiple operating systems on my computer so it's hard to tell which one will be powered on when I want to launch XBMC on my HTPC in the living room. I have a media harddrive that is shared from my PC and both operating systems have access to it. Is there an easy way to have XBMC scan the media drive but not duplicate the entries?

I hope that explanation makes sense.
Thanks!
