Message ‘card1 cannot be accesses’ after taking tons of pics

[Karianderson226]

After taking tons of picture of my kids today and trying to look at them ater, i am getting a message that says ‘Card1 cannot be accessed, Reinsert/ change the card or format card with camera’ i had literally just been looking at all the picture we took, we took some more and it gave me this message out of no where. I have no idea how to access all the pics i just took

Hi there!

Thanks!

Are you by chance using a R5 Mark ii and Sandisk cards? I ask because there is a known problem with certain Sandisk Cards and the R5 Mark ii

Can you read the card on a computer, with a card-to-USB reader/adapter?

Did you, perhaps, fill the card to capacity? Not a good idea. That can trip up a camera. If taking "tons" of photos, have extra memory cards, and switch them out before filling them. This is ALWAYS a good idea, so if a card fails (as yours might be doing) you don't lose all your photos.

Do you have another card, to see if the camera reads it?
