It is possible that the device prevents the system from entering a reduced
power state, in which case the problem is not limited to just the display.
Note that the hard drives are controlled by separate timers.
One thing to try is updating to newer drivers (if available), both for the
device itself and for the USB controller (i.e. chipset drivers).
If on Vista, make sure to enable "USB selective suspend" in the power
management options.
If on XP, there is a hotfix that may or may not help.
