A RAW file system simply means that the file system is not recognized by Windows OS. Therefore all the available file system drivers are unable to mount the file system as a drive. This often happens when the records determining the file system type or location on the disk are damaged or corrupted, usually the partition table (MBR) or the boot sector (DBR).
Since Windows sees no file system in the partition, it prompts "You need to format the disk in drive E: before you can use it" as below when accessing the RAW partition, if we click "No", the raw partition cannot be accessed. On the contrary, if we click "Yes", we will lose all the data stored on this drive. How to access the data stored on RAW partition if I don't format it?
