Iv'e looked around and haven't seen anything similar or in the FAQ, so I'm asking now. 
Whenever I plug the DX into my computer, or turn it on or off, it makes a very annoying noise. I checked the ringers and the event tones and this sound doesn't exist in any of them. I would describe it as close to the "Digital Phone" sound but at a lower pitch.
When I hear the sound, it's usually saying "Preparing SD Card" up in the notification bar. I don't remember it always doing this; I've apparently done something to it in the past days to cause it, but heck if I can find where in the settings to shut it up.
Anybody know what I'm talking about?
