I got a g1w off Amazon, this one specifically. https://www.amazon.com/gp/B00J2OVN74It was work fine for about a day and a half with the 64 gb card I put in, and then mid drive in stopped reading the card. Now I can't get the card to read on any readers or in any devices. Is there a way to save the card? Until I googled and found this forum, I had no idea the cam has problems with 64gb cards!
what card are you using?
how did you format it first? in camera or on a computer?
where did you purchase the card from? there are fake cards on the internet.
