I have a Canon Rebel XT, which I’ve had for years, and have always had the same memory card, but now on the most recent pictures taken it’s saying corrupted data and won’t let me upload them. When I took the pictures yesterday and viewed them they were normal, but now they say corrupted date.
Someone please help.
I have a Mac.
How do you format the card? The pictures are not tremendously valuable, but I’d rather try not to lose them. Is there any way to format or fix the problem momentarily without losing the pictures?
If not, how do I format the card?
