suddenly, all of my sd cards, 4 of them, I can not delete photos. Keep getting the message that they are al write protected , remove write protection first. doing this for years and now this is happening. Can you help me? Tried to format but get the same message.
Have you checked the cards to make sure the write protect button/switch is not in the locked position? You can try the following:
Insert card into reader
Right Click on the Card
Make sure write protection is not enabled. If it is, remove the check beside it by clicking on it.
