If the above-mentioned solution does not work, you can format your SD card to fix the error. Keep in mind that formatting will delete all data on your SD Card, so make sure to back up your important data before proceeding.

Problem 2: The memory card is still being formatted.

If your SD card still asks you to format it, it may show an unknown error. To fix this problem, follow these steps:

  • Connect your SD card to another device or PC to check if there is a problem with the card or device you are using. 
  • If the SD card is running on another device then the problem is your startup device.

Problem 3: The SD card is damaged. Try changing format.

When you receive the message “SD Card is Damaged. Try Reformatting It.” You may be doubtful to proceed with formatting as it will delete all data on your SD card. To avoid this, you can try the following solution:

Check that your SD card is dirty and clean if necessary. Additionally, make sure that the SD card has been properly connected to the slot card.

Solution 2: Reboot your device.

If the problem continues to occur, please try rebooting your device. Sometimes, incomplete background operation may cause the SD card to be temporarily unreadable. Rebooting may solve the problem.

Problem 4: Read/write error on SD card

A reading/writing error on your SD card may indicate that it is being protected from writing, making it impossible to change files. This error may be caused by factors such as a bad virus leak, corrupted disk structure, or incorrect management of the SD card. Here are the solutions to overcome this error:

Solution 1: Basic checks.

Check that the SD card is working on other devices. To rule out compatibility issues. Also check the card reader and device drivers to make sure they work properly. Finally, check the USB cable for any defects.

If your SD card has written protection, remove it from the device and find the lock switch on the left side of the card. Drag it up to turn off writing protection. If there is no locking switch, you can use the PC and Diskpart command tool to remove the only readable properties of the SD card.

Problem 5: Unknown memory card.

If your system or phone can’t recognize your SD card, please follow these steps:

Solution 1: Clean the SD card.

If the SD card contains dust, clean it before putting it into your device.
