That's a RTFM thing (Read The Fricken Manual) as I'm not sure. But you might stumble across it in your camera menu. (under "Format Card or Utilities")
Also check the capacity of your card. If you bought some ungodly huge card - it might be TOO big for your camera. (depending on what memory addressing your camera has, it might not be able to see a card over 2G or 4G, 8G, ect...)
My old Nikon did this when I attempted to put a 4G SD card into it. That camera is 2 years old, so chew on that fact as well.
And again, check that the "write protection switch" isn't flipped if your card has one, and also verify that the pins aren't bent or broken.
Edit: Venture Brothers general theme parodies Johnny Quest. Part of the reason why I love that show. All the grand dreams of back then, of super-futuristic hi-technology / space exploring cultures -- Ultimate grand let-downs.
