I've been at this digital photography thing for a couple of decades now, but I've never run into this issue. Took some shots yesterday with my X-T2. I shoot Jpeg+RAW and slot 2 as 'back-up'. I download the files to a folder on my desktop, then open them in whatever software. I put the slot 1 card in the reader. All of the Jpegs are there, but there is a 25 RAW files missing in the middle of the string. I tried the back-up card from slot 2, same thing. I tried both cards in both the internal and external card readers. No luck. Those 25 RAW files do not appear on either card on either reader. I KNOW the missing RAW files exist on both cards because I can do in-camera RAW modifications. So the files are not 'missing' they are just not recognized by my computer. There is nothing unique about the missing files compared to the other recognized RAW files. I'm stumped. Anybody got any ideas or suggestions?
