My
sd card file recovery becomes inaccessible when I trying to open it on my PC. It says "sd card not formatted". It is a toshiba 1 gb memory card I use in my Canon digital camera. When I have put it in my computer recently to get the pictures from it, a popped up window says "Removable Disk the disk drive F is not formatted. Do you want to format it now? Yes or No? What should I do?"
