Assuming the external USB disk is indeed using its own power, this
suggests the problem is not power and thus a powered hub won't help.
If the USB keyboard is not wireless this also rules out
airwaves interference.
Have you looked at the kernel log? Maybe there are things like USB
disconnects or resets happening because of a faulty USB device
(presumably the disk)?
