How to put Desktop on External Drive/Non-System Partition?

Is it possible to get something like a symbolic link/alias to direct to another folder on an external hard drive and still have the files display on the desktop? I used: sudo rm -rf ~/Desktop sudo ln -s /Volumes//Desktop ~/Desktop But the Desktop is just blank, and when I drag files onto the Desktop, they disappear and are copied to /Volumes//Desktop I recently tried replacing the Desktop with an alias instead, but I now only get a cancel icon popping up next to the cursor when I drag a file over it. The partition is exFat so it's compatible with my tri-boot. I'm doing this so files are automatically available on each Desktop. Any ideas to get this working? I was also thinking about an alternative, something that automatically moved a file to /Volumes//Desktop/ when it was dragged to ~/Desktop and replaced with a symbolic link or alias on ~/Desktop. Is that a viable alternative?
