What does RAW drive mean?
A disk, drive, or any other external storage device that has a RAW file system is often called a RAW drive.

As a matter of fact, a RAW disk is the result of a damaged or corrupted file system. It stops you from accessing the data. Therefore, most users choose to format the drive into other file systems to reach the content.

A RAW hard drive format can result from several reasons. Below list some culprits that put your disk in danger.
