Generally, the SD card will be blank or the card will has some unsupported files when the SD card is attacked by virus; the file system is corrupted; the SD is improperly inserted into the card reader. When you meet with the similar problem, you should think about these questions.
  • Did you take the SD card out when the device was being connected to the card reader?
  • Did you use the SD card in the potentially dangerous computer?
  • Did you directly plug out the SD card without safely removing the SD card?
The above situations can lead the SD card to be blank or cause some unsupported files. Before fixing the SD card, we should recover the lost data from the card.

Step 2: After that, select the suitable file system.
  • NTFS: NTFS is the best Windows file system, given to performance and data security. But it is not compatible with all operating systems. Mac OSX and Linux can read the NTFS partitions, but they cannot modify the inside data. Besides, it is not available in the flash drives.
  • FAT32: FAT32 is an old but still popular Windows file system. Now, it is mainly used in mobile storage devices with low capacity. Each file cannot be over 4 GB in the FAT32 file system. If the hard drive is over 1TB, it should be in the NTFS file system. Besides, some digital cameras, game consoles and set-top boxed merely FAT32, but not NTFS.
  • exFAT: exFAT is the file system used for flash drives in Windows. It is the supplement for FAT32 which doesn’t support flash drives. It supports a file up to 16EB and a volume up to 24ZB.
Check the option [Quick format] and finally click on [Start] to format the SD card.
