"Canon SD Card Error"

This is a common error for Canon camera/DLSR/video camera users when they insert their memory card into a reader. Several popular Canon models are affected, including:

Canon 7D, T5i, 80D, 6D, T1i, Rebel T5, T3, 500D, 5D Mark III...

The "Memory card cannot be accessed" error will prevent you from taking pictures or viewing files. Depending on the exact error message, try [1] re-inserting the card a few times, [2] using a new card, or [3] formatting the SD card in the camera. The goal of these methods is to get the card working normally again.

Before attempting any troubleshooting suggestions, you must first find a solution for digital camera recovery. As long as you cannot afford to lose the media files on the failed memory card, data recovery takes precedence over SD card repair.

Quick tip: If you're using a brand new memory card, make sure to format it to the FAT file system so that your digital camera can recognize it properly.
