    What is the serial number on the bottom of your Backpack hard drive?
    Also, do you see "Series 6 Driver" located on the bottom?

    Try the following from a command prompt:

    modprobe bpck (bpck6 if "series 6 driver")
    modprobe pd

    What happens?

    Does this Backpack work elsewhere? Have you changed either the hard
    drive mechanism inside the Backpack or reformatted the hard from
    its factory format?
