FUJI X-E1 "CARD ERROR"
I've tried reformatting the SD Card with Win7, didn't help. For me, I get the problem after I've shoved the card into a Mac and imported the files in Aperture. The workaround is to press the AE key (zoom out) in display mode, which allows you to regain access to the images again. Bit annoying though......would be interested to see if anyone else has this problem.
