Dear users please help me. I have a 4gb micro sd card. I prefer reading and writing it with my mobile. I tried to delete my all datas and it got deleted. But when I remove the data cable and plug it again, to my surprise the data thai I have deleted reappeared again. I tried formatting it, but pop-up comes saying windows can't format. I tried removing viruses but the viruses too reappears. Please help me out.
