First you will need to ensure that an approved SD card is inserted into the Focus 3D.
If the approved SD card is inserted but you receive this error, try removing the SD card and re-inserting it.
If the error persists, please remove SD card and re-format.
On most computer systems, there are generic formatting utilities available for nearly every form of writable media. In Microsoft Windows systems, the format option can be found in the “My Computer” folder or when the user clicks the Start Button on the taskbar and goes to the “Computer” tab when viewing drives. The available drive letter that corresponds with the SD card inserted can be right-clicked to bring up the drop down menu selection where the “Format” option can be selected. The different format options are available through the selectable options in the format utility.
