So, this seems like an easy one, but I could use a quick tip. Obviously, when I plug my external drive in, the system recognizes it and it appears on my desktop. However, if I eject it, do I always have to unplug and plug the USB back in to recognize it again, or is there a command that will prompt the port to be recognized, and save me the step of having to manually unplug and plug it back in? Thanks.
