The RAW drive is a hard drive partition, which has not been formatted with the NT file system neither FAT (File Allocation Table) nor NTFS (New Technology File System). It can be caused by a number of reasons such as virus infection, format failure, improper system shut down, power outages, etc. In these processes the file system may corrupted and the file system may becomes RAW that cannot be recognized by Windows.

External hard disk drives are usually available as pre-assembled integrated products, but may be also assembled by combining an external enclosure (with USB or other interface) with a separately purchased drive. They are available in 2.5-inch and 3.5-inch sizes; 2.5-inch variants are typically called portable external drives, while 3.5-inch variants are referred to as desktop external drives. "Portable" drives are packaged in smaller and lighter enclosures than the "desktop" drives; additionally, "portable" drives use power provided by the USB connection, while "desktop" drives require external power bricks.
