Hey just a quick note - if you use Final Cut X and remote hard drives, if you have any folders inside it that say DCIM or AVCHD, you won't see your plugged in drive in the event library.  Put _ before each of these straight-from-camera image folders (example: _DCIM) and your drive will appear again.  Don't do this in front of every file, because if you do, FCP won't "see" your events or projects folder.  I spent quite a bit of time learning this, no reason for you to do the same!
