Before formatting your SD Card, please ensure that you do not have any pending uploads. In other words, make sure all of your captures are published (viewable on OpenSpace) before you format the SD Card. Formatting the SD Card will delete all of the data from your device. If you are unsure if all of your data has been uploaded, please attempt an upload using the Desktop Sync App.
Once you've synced all of your captures, use the Garmin VIRB to format the SD card. From the main menu on the camera, use the buttons on the top of the camera to select Setup > SD Card > Format Card > Confirm Formatting.
