Well, today I was using my phone, and I hooked it up to a PC to copy a file off the SD card. I turned off USB storage, unplugged it, and went to set a new wallpaper when I realized... some of them were missing... I checked other folders and sure enough, magically missing pictures.. Now I have seen this happen where it won't see all my audio files, but eventually it kind of just fixes itself and sees them all, but I browsed the SD card, and I cannot even see the missing pictures.. I assume my SD card is corrupting and I should format it. Is this the kind of symptom you'd see when that happens? Or is the SD card physically bad?
