The repair method of the memory card that cannot be read

Now most memory cards have better compatibility, which is convenient for us to exchange data between different digital products. At the same time, with the continuous development of digital products, the storage capacity of memory cards has been continuously improved, and applications are also rapidly becoming popular. But there are also various problems that follow, among which is the problem that the memory card cannot be read. Today I will share the repair method of the memory card that cannot be read.

1. The memory card is broken or caused by poor contact.

Solution: If it is poor contact, take out the card and use an eraser to wipe the gold finger of the memory card to remove the oxide layer on it, and then put it into the phone for a try. If it still doesn't work, pry the tentacles inside the memory card holder to a higher point or apply a layer of glue on the back of the memory card to increase its thickness.

Insert the card into the card reader (make sure the card reader is good), and then insert the card reader into the computer to see if the data in the card can be read out. If the computer can read the card, it means that there is no problem with the card. It may be a problem with the card slot. Try to insert another normal card. If the other card cannot be read, the card slot is broken. You can ask someone to repair it.

2. The memory card cannot be read due to poisoning.

Solution: Poisoning will also cause the problem that the memory card cannot be formatted, which is generally not easy to repair. If the memory card cannot be read due to a virus, the memory card must be formatted. Generally, the memory card that can be formatted can repair the problem. The memory card that cannot be formatted is not very easy to repair, of course, it can also be repaired with the help of memory card repair software. If there is important data in it, use a data recovery tool to restore the data in it, and be careful not to write data into the memory card after formatting.

1. SD card formatting means deleting all content in the memory card, formatting internal storage means clearing data, deleting all data in the memory, and restoring the memory to its original state.

2. But this deletion does not really delete the data, but just deletes the data index, allowing the system to overwrite all the data on the SD card, which means that the entire SD card can be written with new data.

3. This part of data will be kept until new data is written, so the data can be retrieved after the SD card is formatted.

4. Only when the SD card is full of data and all storage space is completely covered, can the data be truly overwritten and deleted.

The solution is as follows:

There are many reasons why the card reader cannot read it, but we can solve it by troubleshooting. First, check whether it is the problem of the card reader, that is, insert the card into the card reader and then insert it into the computer. If the front interface does not respond If you want to change it to the rear interface, if the rear interface still cannot be read, then plug and unplug it with another computer. If it is normal, it means the reason of the original computer, if it is not normal, it is the reason of the card reader.

If the card reader is plugged into another computer and the card reader is normal, then the original computer is faulty. Solutions to computer setup failures:

1. Then click [Start-Control Panel-Add New Hardware-Search] on the original computer, and then check whether there is any external device. If there is, you can open and click [Hardware] to uninstall the driver, and then insert the card reader and reinstall it. Drive

2. Of course, you can enter the safe mode, then repair the registry, and then re-enter the normal mode to plug and unplug the card reader to check the fault and solve it.

If the fault still persists, try to restore the computer to the time when the fault did not occur, or repair the electrical system disk, open the command prompt, enter SFC /SCANNOW and press Enter, and then insert the system disk for repair. There is no need for us to repair it here, the system will automatically detect and repair it.

4. If the fault persists, set the CD-ROM drive in the BIOS as the first boot device, insert the system installation disk and press R to select "Repair Installation".

5. Caused by insufficient power supply of USB. This situation may be caused by too many external devices on the usb interface. The solution: right mouse button [My Computer-Device Manager-find the "Universal Serial Bus usb Root Hub" option], as shown in the figure:

Double-click this option, then open the Properties dialog box, switch to the "Power Management" tab, uncheck the "Allow the computer to turn off this device to save power", and click OK.
