I was told that I could remove my Droid microchip, insert it into a micro SD adapter and transfer photos to my compaq computer. When I insert the card into my drive, the drive does not recognize it is there. Not like my usual Nikon camera memory card for which I have software installed. I was told that Nikon program would also identify the photos on this microcard. Was I instructed wrong? Do I need a USB cable to connect my Droid to the computer and transfer photos that way? Or is there a way to use the product purchased? Thanks.
