WD Worldbook Network Hard Drive to external USB HD Swap.?

I took apart my Western Digital World Book 1TB External Network Drive and am using the 1TB drive in it (Model WD10EAVS) in a external USB enclosure to make it into a USB external drive instead of a Network drive connected to a LAN cable to my router. (Much faster transfer rates via USB).

Its all put together now and the computer will not show the new drive in "my computer". When I click on properties under USB devices connected, it shows the model number and the size of the HD that is connected-(1TB)

I know that the HD is working since when I reconnect it to the network drive enclosure, it can read the files in it. Its only when I connect it to my USB external storage device it does not show in my computer.

I need to know if there is some sort of special software that is preventing it from showing up as a drive in my computer and how I can get this to work on USB.
