Can it be hooked to a hard drive

There are a couple of issues here: connectivity & power.
The Nextbook needs to provide enough power for whatever device you connect. Simplest test for this is to use a USB flash drive since they require little power. For a larger device, be sure the Nextbook is plugged in charging mode to provide the most power.
