I personally have faced this problem and this led me to do looking of a solution of removing write of protection from a memory card, which means you can only copy files and document into the memory card but you can not delete files or format the card which means it like a total waste of money and resources.
This non-volatile memory card format is often used. To prevent data loss, the memory card was created with a write-protect switch, this switch is found to in the adapter and you hardly know that. A little switch at the side of the memory card adapter.
