If by "powered hub" you mean "it has its own separate power supply", then no. Otherwise, I don't know what you mean. It draws power from the USB. The WD disc is powered through it.
Right, a powered hub has its own power supply. Some devices don't work right on un-powered ones. Also, plugging too many items into an un-powered hub can overload the USB port on the host, especially power-hungry devices like hard disks.
