How to Convert/Change RAW File System to NTFS Without Data Loss

What Is RAW File System

A file system, like NTFS, FAT32, and exFAT, controls how data is stored and retrieved. Without a file system, you cannot access and open a storage medium, be it a hard drive, USB flash drive, SD card, and more. RAW file system indicates a state of your hard drive which has no or unknown file system. A disk or drive with a RAW file system is what we called as RAW disk/drive. When a hard drive or external storage device becomes RAW, it could be:

• The file system of the drive is missing or damaged
• The RAW drive has not been formatted with a file system, neither FAT12/FAT16/FAT32 nor NTFS/NTFS5
• The current file system of the storage medium is not recognized by the computer 

The RAW file system can be caused by a number of reasons such as virus infection, format failure, accident shutdown of the operating system, power outages, etc. When a hard drive or external storage device becomes RAW, your device is unusable and you cannot access the files stored on it. Besides, there are some error messages you may encounter when you try to open the device or run CHKDSK on it, like "you need to format the disk in drive before you can use it" and "The type of the file system is RAW, CHKDSK is not available for RAW drives."
