    Yeah that's true, but the USB HDD's usually draw a lot more power though don't they? And yes in my experience it's more the thinner cheaper cables, rather than the actual length itself?

    Thinner cables would affect current as they have more resistance, which could lead to a hard drive not spinning up.

    You get voltage drop, NOT a current loss from resistance.

    Copper wire has a incredibly low resistance, so give the low currents & short cables involved, Its hard to image cable crappy enough to cause issues, but yet there are.
