Ok, Guys I have looked everywhere. I have a Samsung micro 16gb card. It has movies and music on it but I can't delete the files or format the card. I have tried to format it on the computer, epic 4g phone and my K1 tablet. I have used this card on epic 4g and K1 tablet. There is no switch to lock or unlock. Also it has folder called .android_secure but can't delete it.
Anyone have any ideas??
