Watch out, the ground of +12V is NOT -12V. That would actually be a voltage difference of 24V. Likewise, +5V to -5V would be a 10V difference. Ground of this power supply is earth (0V), so connect your grounds to those pins. As for the hub and drive, they probably use very little current compared to the max output of that pin, so you could probably connect those both to that one pin.
