I’ve seen this issue with other Plugable hardware dating back to 2013, but didn’t see this problem posted on this particular TB3 hub so posting here.
I have a USB-C LaCie 2 TB external hard drive (not ssd) and have it plugged into the front-facing USB-C port on my new TB3 hub going into my iMac via TB3. I did manage to do a 600GB backup that took a few hours while I slept, didn’t seem to have any issues with disconnection, as it would’ve interrupted and I think caused the backup to fail. But now that I’m awake and stuff’s up and running, I have received intermittent, random messages that I have “improperly disconnected” my external drive (the LaCie) … note, I the cable connection is solid, and the drive reconnects later by itself, as I can see it available to access in my finder window.
Any clues, solutions, hints, patches, or at the very least, similar problems from anyone else? Thanks all!
