FAT, NTFS and RAW are different types of file
system, but there are some differences between them.FAT is an old type of file system used in
some earlier version of Windows and it can only recognize a small hard drives
full space. FAT is not often used nowadays; instead NTFS is widely used today,
because NTFS has a better performance and security for data restored on hard
disk. The RAW is not a regular type of file system but a system error which can
be caused by virus attack and hard drive corrupted and more. When your hard
drive becomes RAW, you cannot access the data inside and the Windows will show
you drive not formatted error.
