Is anyone else having this issue? After I exit LR, I can't safely eject my hard drive unless I completely shut down my laptop. It's so frustrating that I hesitate to launch LR when I know I am working on other things that I don't want to shut down. Come on, Adobe, don't make me go back to my stand alone LR 5.
We're sorry that you're facing problems ejecting your external hard drive safely after you close Lightroom. Could you please let us know the exact version of Lightroom you're using?
Does Lightroom still run in the background after you close it? (check in the Activity monitor or Task manager to check this)
