Defective, the card is returned to sender in its original packaging (I have not had time to cast) because if it accepts files that I sent him, she stubbornly refuses to delete, not serious I will format it, I tell myself, well nay! she refuses to be cooperative !!! whether in administrator mode or with specific software always same error messages, therefore, not frustrating, I have it "offered" early retirement .... replaced with another of a different brand that I know better shame that it was really cheap, morality and even cheap brand, we always pay for
