This is a common problem with me, but generally easy to fix. My external drive becomes unplugged very often, and if it happens very quickly consecutively, my Macbook will start to see it when it's not there. This usually is resolved by me restarting my computer. But recently (I use Plex, by the way), after a restart, although i can access my external drive, and everywhere in Finder I see it listed by the name I gave it (which is "TOTEM"), through Plex, it is only seen as "TOTEM 1", as if there's already something plugged in by the name of "TOTEM". But nowhere through Finder can I find a phantom device plugged in. Any idea how to fix this? --- Post Merged, Jun 28, 2018 --- Screenshots of volumes from the perspective of Finder, then of Plex.
