Memory Card Issue Pentax K-50

Hi !!!

I purchased a K-50 about a month ago and I installed a Sandisk Pixtor 64gb Memory card in it - it worked -- never formatted it because I was not aware it had to be formatted.

It worked great !!! This morning my girl took out the memory card and downloaded all the pics to her mac book pro -- put the card back in the camera and it gave me a "Memory Card Not Formatted" message on the screen - i tried to turn the camera on and off re-installed the memory card a few times wouldn't work.

3 hours later we downloaded all the pictures to her mac book pro ( they were all still there ) then I put the memory card back in the camera and it works fine -- have not gotten that message and I even downloaded the files to my PC and the card works in the camera again.

since the camera is 3 weeks old I want to make sure it's now a bum camera - any advice would be greatly appreciated !!!

Thanks

There's probably nothing wrong with the camera. I'd say it's the mac's fault.

I am with Adam. There was a rash of that kind of problem a few months back. The cause is difficult to describe, but involves a mix of incompatible file systems due to the Mac having done a write to the card when it was mounted. The fix involves reformatting the card with the formatting software from the SD Association Web site:

Format the card in the camera and you should not have any problems.

The camera only does a shallow format and will not reinitialize the file system. It may do the trick and may not. The big question in my mind is whether it is still read as a 64GB card.

The OP has never formatted the card, unless the Mac automatically formatted it, then the SD Assoc. formatting may be needed. Macs can do some strange things with removable media sometimes.
