The first case is that the memory card is indeed write protected, there is a write protection switch on the card, if 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 card Write protection is a very abnormal phenomenon 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 writing the protection switch on the 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 third situation is that the memory card is plugged and unplugged for a long time, resulting in the metal contact piece, oxidation or wear phenomenon, in this case, use the solution to deal with the memory module, find an eraser, wipe back and forth on the metal sheet several times, generally no major damage can be solved.

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

Fifth, try a different card reader and wish the landlord good luck.

You read the card to see if there is a slider, just slide the slider to the other end, this is to prevent the U disk data from being modified, only read can not write, you can slide the other end to modify the things inside.

After analyzing the structure of the card reader, the following solutions are summarized:

1. Let's see if you have set a password and remove the password.

2. If there is a problem with the card reader, change the memory card and see if the cause appears on the card reader. When it is determined that it is a card reader problem, this is nothing more than related to the card reader write protection port, from the surface of the write guard port on the left side of the card slot, see that there is a metal sheet, after disassembling the card reader shell, you can see that there is a metal sheet on the left side, when the memory card is inserted into the card slot, the two metal pieces are in contact, the write guard is opened, and the two metal pieces are separated after dialing out the card, and the write protection state appears.

3. Finally, the solution: disassemble the card reader shell and push the left metal sheet with a small tool, the purpose is to make the two metal pieces touch as much as possible. Try inserting the card to see if the write protection is turned on!

You can try!

No lock card is written to protect it, basically it is wasted, the landlord changes the card!

Change the card reader (if there is no write protection switch).

One case is that the card reader is indeed write-protected, and the card has a write-protected switch.

The size of the card reader and the card reader itself can not be completely contacted, the working principle of the card reader protection 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 write the protection switch on, which is also the practice of writing the protection switch on the card reader.

The solution is to find a piece of paper that is a little harder and insert it into the card reader along with the front of the inverter to ensure that the metal piece is in full contact.

The three situations are that the card reader is plugged and unplugged for a long time, resulting in the metal contact piece, oxidation or wear and tear, and when encountering this situation, use the solution to the memory module to deal with, 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 card reader itself, or the life of the card reader has expired, so you can only buy a new one or find a merchant.

It means that a circuit in your card reader is broken! - Write the !! of the module section Read is fine but can't be entered! You can try taking apart the card reader and see if there are any areas where the contact is not tight!

You directly use your mobile phone to connect to the computer, see if it is normal, yes, it is really a problem with the card reader,,, in fact, I tried it once, the problem is a detection switch on the SD card reader, due to the time problem, oxidized, the result is a detection error, the computer thinks the SD card is locked, in fact it is not ......

If the detection switch is fine, then the problem is on the main control of the card reader, once the main control chip has a problem, there will be some strange phenomena ......It's not necessarily right to judge whether a card reader is good or bad just because it can read a file, so you'd better try ...... with a different card reader

I also encountered this problem during the computer level exam. In order to ensure the security of data and information, you should turn off the secure read/write protection button of the card reader or USB flash drive.

If you want to remove the protection of reading and writing, you can lock it by flipping the small dial in the opposite direction.

The card reader has a read/write protection function to prevent accidental deletion of files and prohibit changes to disk data.

There is a tiny, tiny switch next to the card reader.

Encountered the same question and sought answers.

You can only copy the files in the U disk for backup, and then format the U disk, your operation damages the U disk, and it is best to detect the U disk before formatting.

Reformatting is sufficient.

Good luck!

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.
