I'm presuming you mean that you wish to display a link on your desktop to the partition that you want to access?Are you using KDE,Gnome or WindowMaker etc as your desktop? Let me know as the way to do what you ask is different depending on which window manager your using.
Also you haven't specified what you want for themes - KDE,Gnome,XMMS etc - you need to give a bit more info so we can help ok?
Let me know the details and I'll see what I can do for you.
Cheers
