What is RAW file system?

When the operating system cannot recognize the SD card of the camera or any device, we can see that the file system of the SD card changes to RAW in the disk management of the windows system. RAW file system is actually a state of hard disk drive or other storage devices with unknown windows file system. Because there is no recognized file system on the drive, there are no files or folders on the drive, and they cannot be used to store data. In order for the operating system to recognize the SD card, the SD card must be formatted as any other file system, such as NTFS or FAT32.


What causes the SD card to display as RAW?

It could be for the following reasons:

  • The SD card is not formatted, or the file system format is incorrect.
  • The file system of the SD card is not supported by the current operating system.
  • The SD card has a large number of data errors or bad sectors.
  • The file system structure of the SD card is damaged.

RAW is not an acceptable file system for Windows and Mac systems. If the SD card is displayed as RAW, the data in it cannot be accessed. To prevent data loss, you are advised to restore the data in safe ways before fixing the SD card.
