In this case, there is still a chance to restore the deleted data .

III. Precautions for using SD card

1. When the power of the device connected to the SD card is low, try to avoid storing or deleting files, so as to avoid data loss due to sudden interruption of the reading and writing process.
2. When using the SD card, do not store too many files and leave some free storage space, which will speed up the device’s reading of the SD card, and the experience will be better. You can regularly back up the files in the SD card to the computer or save them in other external hard drives. When the data is lost, you can retrieve it from the backup.
3. When you don’t need to use the SD card temporarily, please don’t place it at random. This will easily cause the metal contacts on the SD card to be stained, oxidized, broken, or wet, etc., which may damage the SD card and make it impossible to Normal use. It is recommended to use a special box for SD card storage.

4. When connecting the SD card to the computer, you should avoid directly editing or modifying the file data on the SD card, so as to avoid accidental deletion and inability to access these file data due to operation errors. You can transfer all the data in the SD card to the computer and then edit them. Edit and modify operations.
