SD card error problem
I have a Panasonic DMC- FZ7. The problem is that I get a message come up saying that there is an error with the card and to check it. I have the SD card which it says is compatible in the manual. I put the card in my laptop and other camera and it works fine in them. But once I put it in this camera, it sort of freezes and doesn't let me go on the menu or take pictures or anything. After that, the error message comes up and I can't get rid of it.
Is it the camera or the card? And how can I fix it.
Things I've tried:
Formatting the card in my laptop
Resetting the camera
Es esta una buena pregunta?
