My sd card make a error .....and when i delete some thing it says no permission to delete ...and when i move files... i cannot move or copy them ....so please tell me the solution. .except formating
The card is probably corrupt or defective. If you remove it from the device and insert it into your PC, can it be read there? If not, it's dead, and the data on it is lost.
I still think it's a problem with the card. Since SD cards are pretty cheap these days, I recommend getting a new one. If that card is starting to fail, it isn't a good idea to use it anyway for storage of important data.
