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. :)
I just breifly tested this, the loss over a 2m usb cable was incredibly minimal 1-2ma
You get voltage drop, NOT a current loss from resistance.Quote:
