The SD memory card is in the mobile phone, and the file system cannot be recognized and cannot be fo

Hey, just reinstall the SD card.

You first see if there are any scratches on the SD card, the deep kind, if not, use a card reader to back up on the computer and format it.

This phenomenon can be determined to be caused by a quality problem with the memory card. In order to pursue profits, some black-hearted merchants replace the qualified memory cards in their mobile phones with low-cost and low-quality black chips and ** tablets. At first, you may not be able to see anything else, but after a long time, you will find problems such as missing files, partition corruption, etc.

This is a physical damage that cannot be solved by software repair, and can only be replaced with a new memory card.

Smartphones suddenly appear"Empty SD card, SD card with no file system or file system is not supported"Here's why:

1. Maybe the SD card is damaged, and the phone can't read this SD card, so it is displayed like this. You can try it with another SD card.

2. There may be a problem with the card slot on the mobile phone, so that the mobile phone and the SD card cannot be contacted, so the mobile phone prompts like this. You can put the SD card on another phone, if the SD card can be used, then there may be a problem with the card slot. You can also take your phone to a repair shop for testing.

3. There may be a problem with the mobile phone, and the SD card cannot be read, because this prompt will be given. You can put the SD card on another phone, if the SD card works, then there may be something wrong with the phone. You can also take your phone to a repair shop for testing.

My computer, right-click on management, disk, management, find your SD card 4G, 8G, 16G, and then format it.

No, there is only a low-level tool on the Internet to find a low-level hard disk tool.

If it doesn't work, congratulations, the SD card flash memory chip is broken, and you can get a new one.

Try formatting the memory card on your phone.

It may be that the mobile phone is poisoned, and it is better to kill the virus first.

The following is a personal opinion:

One: There are running files in the SD card, if this is the case, the system will prompt those files are running, open the task manager and exit the program to format it.

Second: SD card is written U disk protection, this has to enter the registry to change, the solution is to find it on the Internet, there is a detailed tutorial for clear U disk protection.

Thirdly, the SD card does not support the file format. Some USB flash drives or SD cards only support FAT32 format, not NTFS format, if you choose to format to NTFS format when formatting, it will not be formatted.

Fourth: I don't know, but there must be a fourth... Hope it helps.

It should be a broken card, so change it!

In addition to the files established on the memory card, there are some hidden files in addition to folders such as ***, melogy, picture, photo, video, etc., which is equivalent to a system that allows the mobile phone to identify information.

Under normal circumstances, the formatted card,Put it into the mobile phone,Set the storage location in the mobile phone as the card,It should be automatically written from the new,The landlord checks the relevant information settings in the mobile phone,Some of them will affect the card。

If you can find the card but can't recognize the contents inside, you can format the card once with the phone itself (not the phone).

You can also borrow a recognizable card to check all the files in it, including hidden files and hidden files of the system.

The landlord can also take the card to the mobile phone of the Songkai person to see if it can be recognized and create a file, if it does not mean that there is a problem with the initial formatting process, it is recommended to format it from the new, and the format should not be selected NTFS format.

It is recommended to use your hand to judge the lack of grip on the card format, and do not use the computer to format the card, if you use the computer to format the mobile phone, you should ensure that the format partition format you choose to dig Qing can be recognized by the phone, for example, you choose the FAT format to format the card again.

There are two forms of mobile phone memory card formatting,There are two kinds of dry FAT and TFT (it should be like this,Anyway, I remember that there are two kinds),If you don't have a lack of hands, you can change to another format.。 But it seems that FAT formatting takes up more memory space, or what?,You just use TFT.,Mine is now a defeat and disgusting FAT.,I'm ready to change to TFT format.,It's a lot of space**,Hehe.。

The most effective way (and many of these problems have been solved): adjust your phone's storage method to a memory card, and then the phone will automatically prompt you that the phone's memory card is not formatted, and ask if it is now formatted, you select "Yes", and the phone will be automatically formatted, and the format is complete. On the computer, there will be three folders on your memory card, which are to store sound, **and**, classify the information contained in your base book in the designated folder, and then insert the memory card into the phone, you can use it!

It's time to give me extra points! ）
