Run a Command Prompt as administrator, and enter "format /FS:fat32 X:", the X being the drive letter. If that doesn't work (or if I got the command wrong, in which case I apologize), then there's a program called Swiss Army Knife that should let you format. Good luck, hope you get it working. I just had to format my new HDD myself earlier, but I did it in a drastically different way, and it took forever. Formatting it to fat32 should be a lot easier than wiping and recreating it, then formatting to WBFS was for me.
