What Causes Hard Drive Corruption?
When a drive is formatted with a file system such as NTFS, FAT16/32, exFAT, etc., it creates a table where file records are stored. NTFS creates Master File Table (MFT) while FAT file systems stores these records in File Allocation Table (FAT). After format, every file you cut/copy/paste enters a record in the table.
These file records contain the physical address of the file on the hard drive along with other file details such as file format, creation date, modification date, size, etc.
So when a drive is connected to the system, the OS reads the file system's table and displays the contained files and folders along with the details fetched from the table. When this table is damaged, the OS can't recognize the file system and thus, shows drive as RAW.
