This is my first time using a TF card. I heard that it needs to be formatted on the mobile phone before it can be used, so I formatted it. Who knows? It turns out that it cannot be used after formatting. It prompts that the file configuration is incorrect and cannot be opened on the computer. It prompts that the files and directories are damaged and cannot be read. When I right-click on the computer and format it, it says that it is write-protected and cannot be formatted. It is stuck. It's a Kingston, 1G. When I open the file management on my phone, it shows a total of 980MB, and the available 115MB, but I can't save the file. I'm confused. I haven't even used it since I bought it, but something went wrong. I think yours should be the same as mine. Try it. The following method must work, just try it a few times. Use the card reader to do the following:

Click Start –>DOS Command Prompt –>FORMAT X: –>ENTER, wait for completion. X is the drive letter of the TF card on the computer. It can be opened after the format is completed.

First, please confirm whether your mobile phone memory card has a write-protect switch. If so, turn off that switch. Just remove it!

If the mobile phone memory card does not have a write-protect switch, please see the following three solutions:

First, the mobile phone memory card can be read normally on the mobile phone; After deleting a file, the card reader prompts "write protected". This is a problem with the card reader. I once encountered such a problem. Unplugging the card reader from the USB port and then changing it to another USB port solved the problem. This is caused by poor contact between the card reader and the USB interface!

Secondly, the mobile phone memory card can be read normally on the mobile phone, but the files cannot be deleted. This is a problem with the memory card. Generally, it should be done once Formatting can solve it.

Third, there is a problem with the card reader itself. It may be that the card reader is broken. You can try another card reader. If you have other memory cards on hand, insert other memory cards into the reader. Try it on the server to see if this happens!

You open the properties, remove read-only, select archive and it will be OK!

The memory card is write-protected, how to remove the write protection?

There are many reasons for this situation with mobile phone SD cards. The specific analysis is as follows:

1. The memory card is write-protected, such as RS-MMC card. There is a write-protect switch on the card. , if write protection appears, it is recommended to check the memory card itself.

2. The memory card does not have a write protection switch. It is a normal card. It is very abnormal to have write protection. It is probably because the size of the card reader cannot fully contact the memory card itself. , ensure that the metal pieces are in complete contact, and can be pressed into the card reader by hand.

3. Due to long-term plugging and unplugging of the memory card, the metal contact piece has become oxidized or worn. You can find an eraser and rub it back and forth on the metal piece several times. Generally, there is no major damage. All can be solved.

1: The memory card is indeed write-protected. There is a write-protect switch on the card. If write protection appears, it is recommended that you check the memory card itself.

2: The memory card does not have a write-protect switch, it is a normal card. It is very abnormal to have write protection. This is actually because the size of the card reader cannot fully contact the memory card itself. The working principle of the memory card protection is actually to control the contact area of ​​the metal contact points. If it cannot ensure that all the metal pieces are pressed down, the write protection switch will be turned on by default. This is also the way to solve the problem of the write protection switch on the memory card. The method is actually to find a piece of harder paper and insert it into the card reader along with the front of the memory card to ensure that the metal piece is in complete contact. You can also press it with your hands and feed it into the card reader.

3: Due to long-term plugging and unplugging of the memory card, the metal contact piece has become oxidized or worn. If this happens, use the same method as the memory stick. Find an eraser and wipe it on the metal piece. Rub it back and forth several times, and it can usually be solved without major damage.

4: 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 dealer.
