USB3 won't power 2,5" external HDD

I have just tested a 5TB Seagate Backup Plus drive with my PineBook Pro
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).
