Those tips are important for any deleted or lost data recovery. They can help you maximize the number of recoverable files. Moreover, it may save your time or even money on data recovery.

  1. Stop using the SD card immediately. If you are aware of lost files on the SD card, don’t keep using it to save any more data. For example, don’t put the SD card back to your digital camera and take photos. The writing operations might overwrite the original files, resulting in corrupted and unrecoverable files. 
  2. Find out if the computer can detect the SD card. Go to the Disk Management on Windows or Disk Utility on Mac to see if you can find the SD card in the disk list. If not, it is very likely that the SD card is physically damaged and beyond any data recovery you can do.
  3. Check the connection between SD card and the computer. If you insert the SD card to a computer via an SD card slot, try to use a reliable SD card reader to reconnect it to the computer. Meanwhile, if you connect the SD card to the computer through a card reader, change to another card reader too. A poor or instable connection could cause the SD card malfunctioning. 
  4. Run First Aid to repair the SD card. Mac’s First Aid in Disk Utility can check and repair slightly corrupted disk. In some cases, you will be lucky that the SD card can be fixed and all data is safe. 

If your photos and videos are still inaccessible after all the activities above, you will need a professional SD card data recovery tool to accomplish the data recovery task.
