Hi people. i Have notice one thing. If i put into my card reader a sony card of 512 mega , the reader read it correctly. If i put another sony of 32 mega the system don't recognize it. I tri also with a SD of 32 mb and don't work. Then i reinsert the 512 and don't go. I must restart the pc and the system view the 512 mb card . Everytime i try the other, the system don't read all cards. Someone with this problem?
