Using the stock, updated, out-of-box software...
USB 3 socket : Works perfectly, plays videos with VLC fine, ejects safely.
USB 2 socket : Powers and clicks a lot but does not appear to function properly - no device shows up.
USB C socket : Appeared to power up initially but after a few seconds it just powered off and died.
Retrying in the USB 3 socket worked fine again and was able to eject safely.
Running off a power bank with a power meter connected shows short high starting current of 670mA dropping to a quiescent idling current of 240mA.
(Since my power meter only refreshes its display a few times a second the peak current might be much higher).
I have a Seagate Backup Plus Portable 5TB and a silicon power armor with the same HDD. None work in USB3. The silicon power works fine in USB-C. The seagate will spin up but won't mount (won't even be shown in the device notifier (I'm running Kubuntu 19.10)). Both work fine on other systems. I guess I'll order one of those USB measurement thingies, to see what's really going on the with the voltage and currrent.
