There are two scenarios in which a memory card is write-protected

1. The card reader or card sleeve (such as the card sleeve of TF to SD card) has a write protection switch, as long as the switch is found and pulled in the opposite direction, the protection can be released.

2. If there is an error or the memory card has been damaged, you can use the disk repair tool that comes with the system to try to fix it. If it cannot be repaired successfully, the memory card is basically physically damaged, and for the memory card, it is basically scrapped.

One case is that the memory card is indeed write-protected, compared to the rs-memory card, there is a write-protect switch on the card, if the write-protection appears, it is recommended that you check the memory card itself

The second situation is that the memory card does not have a write protection switch, which is the normal kind of long card, and it is very abnormal for write protection to appear, and it is not what those people say, add a password to the card in the mobile phone, pull something, obviously, you add a password, open the card on the computer, and the input decoding window will appear

This is actually because the size of the card reader and the memory card itself can not be in contact with the complete The working principle of the protection of the memory card is actually to control the contact area of the metal contact point, if it is not possible to ensure that all the metal pieces are pressed, it is the default to the write protection switch is turned on, which is also the practice of the write protection switch on the RS-memory card

The solution is to find a piece of paper that is hard and insert it into the card reader along with the front of the memory card, so that the metal piece is fully in contact and you can also press it into the card reader by hand

The three situations are that the memory card is plugged and unplugged for a long time, resulting in the metal contact piece, oxidation or wear, and when encountering this situation, use the solution to the memory module, find an eraser, wipe it back and forth on the metal sheet several times, and generally no major damage can be solved

The four situations are that there is a problem with the contact piece of the memory card itself, or the life of the memory C card has expired, so you can only buy a new one or find a merchant
