Help installing a HDD in a Sans Digital TR4M

I went to fry's Electronics looking for more HDD Space and told the Guy I wanted an enclosure that will hold multiple HDD and can stream media with no problems. He showed me the Sans Digital TowerRaid TR4M. So I picked that up and a 2TB HDD said it would work like a charm. So I was excited went home put the Card in my PC. Installed the Drivers plugged the HDD into the TR4M and its not showing up in my computer. I restarted my computer still nothing. so I did another restart and went into the Raid Configuration thing and my HDD showed up and I did a Low Level Format hoping that would fix my problem. Still nothing. When I open up the SataRaid5Manager I see my 2TB HDD in Channel 1 saying I have 1.81 TB Available. I am unsure how to get this to show up on my Computer so I can easily Transfer Files to it.

Not sure if this matters but the Lights on the TR4M are
Power: solid amber
Host: solid green
1: Solid Green
2: none
3: None
4: none

I am running Windows Vista Ultimate 64 Bit.
