Hi all, I have a Micro SD card (4GB). When I put it to my computer (windows 7 ultimate 32-bit) from USB port, I can't access into it. And writes "Removable disk G:" (like below image) and doesn't show other specifications of that volume. And when I double click on it, a pop up window appears and says "Please insert a disk into removable disk G:". I used some commands line "chkdsk /f G:" in command prompt window, but it also writes "can not open volume for direct access". And also right click does not work on that volume for format it. In the command prompt also formatting results the same for chkdsk /f g: as message unfortunately. Is there any way to access into that volume? Thank you.
