Like I said I recently received a GoPro so I don't know how to do that
You may want to check my videos (link in sig) as I have tons of videos on how to use the GoPro, along with plenty of reviews on accessories etc.
As mentioned, you need to format the card in the GoPro.
Press the Power/Mode button until you go through the shooting modes and get to settings.
Press shutter button to enter settings.
Press mode button until you get down to the Erase menu (little bin icon)
Press shutter button to select
Press mode button to select 'ALL'
Press shutter button to select and confirm the action
The card will now format.
Press the button on the side o the camera (the small wifi/settings button) to exit the menu and jump back to the shooting mode.
If you need any more help feel free to give me a shout - as you'll see from my YouTube videos, Im rather experienced with GoPro's!
