First, make sure you have done the basics.

  1. Use a clean and dry towel to wipe the SD card carefully to get rid of any material that may affect the computer reading the piece.
  2. Use another SD reader or another computer to see the SD card works normally.
  3. Restart the computer to refresh the system to terminate any software issues that may prevent the computer from recognizing the SD card.

If those still can’t change the RAW situation, you can get your hands on the following solutions.
