Remember, the drive must be formatted before Windows can 'see' it. If you haven't formatted it yet, click here for instructions on one way to go about it.
If you have formatted the drive and it's still not showing up, click here to download TweakUI from Microsoft. Run it, expand My Computer, and select Drives from the left-hand column. Proceed to scroll through the list of drive letters and place a checkmark to every one that does not have a red question label attached. OK your way out then check My Computer again and see if the drive's listed.
Hope this helps,
