Hrm... did you install the software and what kind of computer is it?

If you want it to read like an external drive (ex. hard drive, thumb drive) switch USB mode to M (mass storage) in the set-up menu (I think its the wrench icon)

You'll love it! wait till you get a wider angle lens, its a whole new world.

I would be glad to help you out in any way I can with regards to getting the images onto your computer.
