Perhaps, you have plugged your SD card into your personal computer and unfortunately it shows “disk not formatted” or “format the disk in drive” error. When that happens, you are more likely to run the CHKDSK to check the error and repair it. Again, that might fail to solve your problem and only display a message telling you that the file system is RAW and CHKDSK is not available for the RAW file drives. That should tell you that your SD card has turned RAW and you cannot access the files. To access your files again, you must format the SD card from RAW to NTFS, FAT32 or any other file system.
The message “The type of file system is RAW” also prompts when trying to convert a microSD card or an SD card from FAT32 to NTFS in the CMD. RAW file system errors are among the commonest topics of discussion on Windows’ forums and in fact, the errors occur on pen drives, USB flash and external hard drives as well. Now, your big question might be what is a RAW file system? Or, what causes the RAW file system?
More about RAW file systems
Generally, Windows operating system does support every file system and RAW file systems are among the unsupported. It supports FAT32, NTFS, exFAT, FAT16 and many other files. Each time it detects a RAW drive, it reads it as an unformatted drive. The drive shows RAW in the Disk Management and does not appear correctly in the File Explorer. In other words, Windows cannot access it or recognize it.
If your SD card became RAW unexpectedly and suddenly, there are chances that its file system is already damaged or corrupted. The system tables might be damaged or the type of file system information might be missing – that arises due to improper removal of the SD card. Even more, computer virus infections or hacker attacks can cause RAW file systems and show 0 bytes. The next thing that should be in your mind is how to do the repair work.
