To format an SD card, insert it into a Windows computer/laptop and follow these steps: (check attached screenshot)

  • Go to "My Computer" or "This PC" in Windows Explorer
  • Right click on the removable SD/USB drive (may be E: or F: or G: or...)
  • Select the Format option (a pop-up window will open)
  • Ensure Quick Format is checked (no need to update the other options)
  • Click on the Start button... done

OR it maybe just easier to install a new SD card.  

NOTE: We do not recommend purchasing an SD Card from a 3rd party as it may be incompatible with our products. Please purchase the SD card from Parts Online (Part No.: 22067) as they are pre-formatted to work correctly with any Data Signs product.
