The K-1 has dual card slots. *IF* it was my card and I didn't want to just replace it, I think I'd put it into slot 2 & set the K-1 to write to both cards simultaneously.
Shoot photos & download to the computer. Rinse & repeat ... several times until you're sure the card is reliable. Or until it fails. You'll still have your photos on the card in slot 1. Although ... the fact that it worked the next day is probably because the problem WAS caused by Windoze. On 5/13/2017 12:46, jtainter wrote:
Last fall I bought a K-1 with a Sandisk 64 gb card. I have just now gotten around to calibrating my lenses for autofocus. Partway through this exercise my system (Windows 7) would not recognize the card. It had recognized the card fine up to that point. I tried going through a Lexar card reader on a USB port, but Windows kept saying that the card had an unrecognized file system and offered to format it for me. I reformatted the card in the camera, but with the same result. I then got out an old 2 gb card, formatted it for the K-1, and Windows 7 read it just fine. So the camera and computer are working okay. At this point I thought the 64 gb card was faulty. But it is only about six months old and has only about 150 images written to it. (I've been too busy for photography). Then the next day I put that non-working 64 gb Sandisk in the computer, and Windows read it fine. So, one day it works, a few hours later it doesn't work, and the next day it works again. Can anyone pinpoint what the problem might be? Specifically, can I trust this Sandisk card? Thanks, Joe
