Some context:
I plugged my LaCie Rugged Mini into my MacBook Pro (via a Satechi Type-C Pro Hub Adapter) to transfer some folders over and it functioned as normal. When I pressed eject, I was denied as "another program was using it" (which wasn't true). Just as I opened Disk Utility, my LaCie finally decided to eject itself, though I did so through DU just to be safe.
I decided I plug it in again. As waited for it to show up on my desktop, I noticed the LED light from the hard drive disappear. I quickly opened DU to find my LaCie listed as "Uninitialized Disk". It disappeared and I then received a message stating that my hard drive had been ejected unsafely.
I plugged it in once again and it showed up and appeared to function as normal again.
Still, I'm slightly concerned as I don't think I've ever experienced something like this.
