I recently got a new phone (upgraded from LG Vortex to Droid Razr M). I used the same SD card I had or the LG phone. I needed to turn my phone off earlier today, and after turning it back on my gallery pictures that were on my SD card were gone. All of my downloaded pictures from messages were still there, but none of the pictures I took with the "camera" of my old phone were there. They were there before I tuned my phone off though. I tried turning my phone off/on again to see if that would fix the problem, and now all of my pictures on my SD card are gone. I also tried unmounting/mounting the SD card but that did not work.
