How to Fix It
-
Format the card in the camera.
Menu > Setup > Format memory card. This creates the correct file system for your specific camera. WARNING: formatting erases all data — copy photos off first.
-
Check card compatibility with your camera model.
Older cameras may not support cards larger than 32GB or SDXC format. Check your camera manual for supported card types and sizes.
-
Try a different card from a reputable brand.
Counterfeit cards (especially from online marketplaces) may not work correctly. Use SanDisk, Lexar, Sony, or Samsung cards from authorised retailers.
Frequently Asked Questions
Why does a card work in my phone but not my camera?
Phones and cameras use different file systems and folder structures. A card formatted by a phone may use a format the camera does not understand. Always format the card in the device that will use it.
Can fake memory cards cause this error?
Yes. Counterfeit cards often misreport their capacity and use unreliable memory chips. They may appear to work initially but fail under camera use.
