Can anyone help me I'm really getting cheesed off trying to get my USB STICK to show up on my MaxDigital 1000

I'm not even sure if i have the right USB for this digi box.

I've searched everywhere and cant anything about how to fully setup the USB STICK for the digi box.

If it turns out the USB STICK is the wrong type for the MaxDigital 1000, then can anyone recommend the right USB STICK or even a external HDD drive so i can start to pause, record etc etc, cause up to now I can't do anything. The USB STICK doesnt even show up in the menu on the digi box.
