How to erase or format a micro SD card with ISO files copied on it.
I have a 3 gb micro sd card in a sd card adapter. It came formated as fat32, and I downloaded some ISO files to move to another computer. The move is done, but now I can't erase or format the card. I get an error saying that it is read only. I have toggled the lock switch, but all that did was let me copy the files to trash, not permanently remove them. How do I change the permissions on this card and the ISO's on it, to allow me to erase it? Googling reveals that many people seem to have this problem, but the only suggestion is to slide the lock switch or format, but that isn't working for me. Gparted isn't seeing the sd card.
