"My Nikon D5200 is using a 16GB SD card. This morning I got the error message saying [this memory card cannot be used, card may be damaged, insert another card]. I put the card in the card reader and connected to the computer, it didn't show up, either. Great, what am I supposed to do now?"
Why can't this memory card be used all of a sudden? Usually, when a memory card is no longer usable on a device like a digital camera, Android phone, or a game console, it's probably because it has been locked, corrupted, damaged, or broken.
How to Fix This Memory Card Cannot Be Used
If you got the error message on your Nikon camera, try the following methods first to try to solve the problem.
Method 1. Confirm the Card is Correctly Inserted
Take the SD card out of your camera and put it back again. Make sure the insert direction is corrected. You can hear a click sound with some cameras when the memory card is correctly inserted (usually SD cards).
Method 2. Ensure the Card is Approved
Check the approved memory card compatibility charts of Nikon, make sure Nikon approves the SD card you use.
Method 3. Check the Memory Card Contacts
Take the card out and gently clean the contacts using a soft dry cloth (not applicable to the CF-type cards). Make sure no dust is left on the contacts from the cloth. Re-insert the memory card.
