OK, so I guess obviously the USB port must supply some
amount power or
even a simple flash drive wouldn't work as the memory in it has to
require some sort of +/- supplies to function at all.
In terms of my external USB hard drive, I have 3 like the following
link except mine are 500GB.

This drive ships with an external wall wart power supply and doesn't
function without it on any machine I've plugged it into.
Yep, that device will not work when used only on usb-power. The 3.5" disks
need 12V, which the usb doesn't provide.
What I have here and what works with one connector on my laptops and needs two
on my desktops is a case for a 2.5" disk. (The disk I got from my brothers old
laptop.)
Have fun,
