Too many of these 2.5" drives take more than 500mA on spin-up, killing some laptop USB interfaces. Most people have no clue about this, and won't bother plugging in both cables.

A properly-designed unit would first check for sufficient power being available, or use a drive with modified firmware that would spin-up much more slowly.

MacBook Pro users are ok - USB ports are rated at 1.1A.

But A. Coward, don't you know that Macs are bad? Who in their right minds, apart from someone who liked stuff to work, would buy one of those monstrous contraptions?
