I have an issue on my external HD and Lightroom. I importerd photos from my external HD and it went fine. Next time i plugged HD in it poped up as a new HD on the left panel. Now in the left panel there is my mac's HD and the external HD twice. The dublicate ex-HD has the same info, size, color, photo count, than my mac's HD, but folder structure is the same than the original external HD. How can I remove the dublicate? I can attache a picture later on.
I'm using Macbook Air and the latest OSX. Lightroom CC is yet on trial.
