What is a RAW Drive?

A RAW drive is a hard disk drive, external hard drive, or other storage media that the operating system cannot recognize. In general, a drive is formatted with a file system that allows the operating system to access and write data on the drive. The most common file systems are NTFS, FAT32, and exFAT currently.

However, a drive may become RAW due to a number of reasons, such as virus attacks, file system corruption, or physical damage to the drive. When a drive is in RAW format, the file system may be missing or damaged. And then, the drive becomes unrecognizable and cannot be organized or managed by the operating system.

Many users suffer data loss from a RAW drive because all the files and folders on the drive become inaccessible. Only by formatting RAW to a new file system can you continue using the drive. Hence, it is essential to fix the RAW drive as soon as possible to rescue your data and reuse the drive. There are several solutions to recover RAW drive data and repair RAW drives on Windows 10/8/7.
