Is there any way I can hide all files and folders from the OS X Desktop, but leave the Hard Drive(s), CD's, External Drives, Network Drives there?

I was hoping there was a way I would be able to make all folders and files hidden on the OS X Desktop, but leave the Hard drive(s), network drives, CD's/DVD's, etc. But if I was to go into the Desktop Folder using Finder, the items would still be there. So, basically the opposite of the Finder Preferences of showing specific items on the desktop, to hide the files, etc. but leave the HDD's, CD's, etc.: Thanks a lot
