Windows 7 wont recognize WD Elements 2.5TB External USB HD?

Just like it says. Just got my new hard drive today. It is a Western Digital Elements 2.5TB USB 2.0 External HD. I plugged everything in and got nothing. It is not being detected at all by windows though the light on the drive is coming (and staying) on. I went into the BIOS and PnP is on auto and usb is set to 1.1 + 2.0. I have tried a couple of other things but have not had any success. I am currently downloading some new drivers for windows but do not have any other ideas at the moment. Any help would be appreciated.
