What s going on with the memory card being write protected?

Hello, about the write-protected solution of MMC card.

One situation is that the MMC card is indeed with write protection, than the RS-MMC card, the card has a write protection switch, if there is write protection, it is recommended that you check the MMC card itself

The second situation is that MMC does not have a write protection switch, which is a normal kind of long card, and it is very abnormal to have write protection, and it is not what those people say, adding a password to the card in the mobile phone, pulling or something, it is obvious that 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 MMC card itself can not be in contact with the complete MMC protection working principle is actually to control the contact area of the metal contact point, if you can not ensure that all the metal pieces are pressed, the default is to write the protection switch on, which is also the practice of writing the protection switch on the RS-MMC card

The solution is to find a piece of hard paper and insert it into the card reader along with the front of the MMC 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 MMC card is plugged and unplugged for a long time, resulting in the metal contact piece, there is oxidation or wear and tear, and when encountering this situation, use the solution to the memory module, find an eraser, wipe back and forth on the metal sheet several times, generally no major damage can be solved

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

1. If the mobile phone is poisoned, clean it up with a mobile phone assistant.

Second, the mobile phone program responds slowly, cancel the connection, shut down, turn on again, and reconnect should be OK.

3. If the above does not work, the card is broken.

You find the memory card option in your phone, then set it up and remove the password from the memory card.

Then when you use the card reader, the memory card is not write-protected.

Resolution.

1. The first situation is that the memory card does have write protection, which is different from the RS-memory card, and the card has a write protection switch. The solution is that if there is write protection, it is recommended to check the memory card itself Generally, there will be a small switch on the memory card, and you can turn it on to the other end.

2. The second situation is that the memory card does not have a write protection switch, which is the normal kind of card It is very abnormal to have write protection It is not what those people said to add a password to the card in the mobile phone or something Obviously, after adding the password to open the card on the computer, the input decoding window will appear This is actually because the size of the card reader and the memory card itself can not be completely contacted 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 impossible to ensure that all the metal pieces are pressed, The default is that 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 actually to find a piece of hard paper and insert it into the card reader along with the front of the memory card to ensure that the metal piece is completely in contact You can also press it into the card reader by hand

3. 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 deal with the memory module, find an eraser, and wipe it back and forth on the metal sheet several times, generally no major damage can be solved

You take it out and take a closer look at it, and there's a little buckle on the card that you can move up and down, and if that thing is in the lock direction, it's locked and protected, and you want to delete the card thing, and you have to move that thing in the opposite direction. You can try.

There is a small switch on the reading card, just move it. There's a little bump next to your phone's memory card, and you can flip it to the other side to remove the write protection. This is the protection measure that comes with the memory card There is a write protection switch on the memory card, if there is no write protection switch, it means that there is something wrong with your machine, there may be a virus The write protection switch of the memory card is on the corner of the memory card, it is like a slider, you can pull it down; The write protection switch of the USB flash drive is generally on the side

Hehe.. You take out the memory card. There's a movable strip on one side of the card, just push that strip down.
