Alright, here's what I'm trying to do. I mount an external volume for work purposes, on which I have a folder that I'd like to appear under "Places" in the OS X sidebar. You with me? Good. 
Okay, if the volume is mounted, OS X happily adds the shortcut to the sidebar. But, as soon as the volume is dismounted, the shortcut disappears, which would be fine, except that it doesn't reappear when the volume is remounted.
See my dilemma? The purpose of the sidebar shortcut is lost in all of this.
Any ideas/suggestions?
