RAW drive

RAW drive also calls RAW file system, 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).

Sometimes a damaged volume may lose its file system type. Various error messages may appear, most common being:
The volume X: is not formatted. Do you want to format it now?
The disk in drive X: is not formatted.
The volume does not contain a recognized file system
Drive X:\ not accessible. The file or directory is corrupted and unreadable.
There was an error accessing drive X:. The disk is not formatted.
