The storm comes with an 8gb micro sd not a mini sd, the mini sd is physically larger. You don't have to format the memory card since it comes preformatted with the correct folders already on it. If you use another microsd such as a 16gb microsd with the storm, make sure to format it on the storm so that you get the correct folders.

I did the same as the guy above and unsafely disconnected the phone, but my phone won't let me format my card. how do I format on a computer? I have a flash drive with a micro sd insert.
