I dropped my razr hd and it landed on the bottom right side (looking at the screen). Ever since that my phone either wants me to format the card since its corrupted or just doesn't recognize it's their. It happens randomly when i'm listening to music or using the internet and i just get a notification in the top bar saying to format it. When i remove it and put it back in it works for awhile. I tried it in another phone and no problems. None of the data is corrupted though. I haven't tried another sd card in the phone since i have none.
