Okay so I Unmounted my memory card for safe removal and I removed it and put all my pictures onto my computer like I ALWAYS do and I went to put the memory card back into the phone and I did and now it is telling me that I have a "Blank External SD card" and it says "SD card blank or has unsupported file systems". What the heck do I do? I don't know what happened, I didn't add anything to the card or do anything to it except for remove it take the pics off and put it back in. I did it the correct way. What do I do???
