I just bought a used 600D and am feeling a bit down and will likely return it. I have tried using different SD cards and I always get the same message "SD card write protect switch set to lock". The SD card is definately NOT locked and I've tried wiping the cards, formatting the cards, and checking in the SD slot (doesnt look like anything is loose or jamming the lock switch area), not sure what else to try. This forum is my last resort before throwing in the towel and returning it. Any ideas/experience with this issue?
