memory card wont formatt.

Hi @mrfrogman ,

Have 64GB cards worked in the camera before?

If not, as your camera model is fairly old (released in 2006), it may not be able to handle such a large capacity SD Card.

According to the User guide the maximum capacity card that is guaranteed to work is only 4GB.

You could try inserting cards, having a capacity of 8GB, 16GB or 32GB to see if one of them might work, if you want storage capacity greater than 4GB. I suggest that you try 8GB first and then work up until you know the maximum capacity that will work.
