Raw Filesystem
In Microsoft Windows a drive reported as "File System: RAW" could mean that all information referring to the partition and the file system have been lost.
On a brand new drive RAW file system is a kind of original file system before format, which cannot be recognized by Windows. Therefore, naturally, you need to format this drive and change the RAW into NTFS or Fat32, which is the files system after the format.
On a formatted drive RAW file system is usually an indication of a problem, like the drive going bad, or somehow the file allocation table has been lost. If the drive is a hard drive, it could also mean damage to the MBR (Master Boot Record) "Boot Sector." The RAW drive condition can occur on a hard drive, and on other storage devices like a flash memory card. It may show a memory card error on your camera, smartphone, or it may be shown as a RAW device under the Microsoft Windows operating system.
There are two places where we store file system information: the MBR partition Table and Volumes boot sector, When the file system information provided on these 2 sectors of disk is not good you may see chkdsk reporting raw file system (though the data is still there).
