It didn't crash the board at least, so that was nice.
Expected behaviour. Maximum amperage when USB ports are fed through the PMU (power management unit) are 650mA. Most 2.5" disks need slightly more when they try to spin up. On the 2GB board you can use a jumper to power USB peripherals directly from DC-IN and not the PMU instead (only drawback: when you want to use a battery in such cases PMU + step-up converter won't provide power to the USB ports when running on battery) so on the 2GB board you won't have the problem if you power Pine64+ through Euler pins (since Micro USB is simply crap to provide power to such a setup)
