I can't format my 64g card

I have a 64gb micro sd card. im using it on my canon camera after few times use, I can’t format the card, i tried swotching the side of the adapter, still it says it is write protected and cannot format the card.

:smiley:   Hi Neosaid,

Dear member of SanDisk Community, welcome.

Please, see if _have the logo SDXC _, in the camera or in guide.

If have the logo, return the card, it’s defective.

If not have the logo, then, use card up to 32GB SDHC.

Also, for some information on the topic, see the following article:
