Ice cream sandwich tablet saying the internal SD card was removed? I just got this tablet, and I was playing on it. Out of nowhere, it said SD card removed. The only problem is it's an internal SD card. So I didn't remove it. Now, it says there is no memory on it. Anyone else have this problem, and know how to fix it?
What exactly did happen there for that to occur? 

The only way this can happen is by going into Settings > Storage, scroll down to the bottom and it says "Unmount SD Card", at this point it is already unmounted so that would show by now the following "Mount SD Card"?
