After the last update, my sd card would constantly "dismount". If I turned phone off and back on, it would work but only for a short while. I decided to copy everything off it and then erase it. That seems to have fixed the problem. No, i haven't tried to load the stuff back on it. Saved me from buying a new card anyway. We'll see how long this lasts. It's been almost a whole day now and it would never stay mounted that long before.
