Hey Guys, For some reason one of my 16gb cards will not mount from any of my Cf readers. I use Lexar firewire 800 and a couple of other cheaper ones. The card however will read from the camera but thats the only way I can get material off of it. I tried reformatting it in the camera and still no success. All of my other exact same cards work perfect. Does anyone have any suggestions on how to fix this problem I figure its a file structure problem within the card.

Thanks
Jason

Sorry for the obvious, have you formatted it in camera after taking off the current files?

Ya I reformatted it in the 7D and I tried the Sony Z7 as well still no luck.

Send it to SanDisk with a short letter explaining the problem.

My guess is that they will replace it.
