The camera would not let me format...I tried. After reading some posts about maybe putting tape over a notch in the adapter, I took out the adapter. There were 2 slots...one small, one long. I started looking at the adapter as I KNOW I have used SD cards in the camera before. But this micro did not have an adapter with it. The adapter was from my old Laptop...Toshiba was on the adapter. I found another adapter, and put the Micro in it. The camera let me use the SD card. But thank you for answering..have had problems getting people to answer my questions on other forums.
