I have an SD card with 16 pictures on it, I want to add more pictures,when I try I get this box.
The disk is write protected remove the write protection or use another disk.
I cannot work out how to remove the write protection, from the SD card. The card is on a USB addaptor, and connected to my computer. I get the same box if I try to load pictures direct from my Olympus camera. I cannot remember how I got the 16 pictures on in the first place
