  • Virus intrusion: entry of virus either to your system or to your SD card might corrupt your SD card. Then it becomes difficult to access.
  • Dust or oil stain exists on the surface of SD card: check the state of the metal area on SD card to see if they are in sound condition. If dust or oil stain is found, please use cotton (along with alcohol/water) to clean its surface gently.
  • File system corruption: file system contains necessary information about all the file types of your SD card. It may get corrupted due to insufficient disk space during file system conversion or due to an interrupt caused during working process, making it impossible to access.
