Your USB drives usually come with a pre-installed file system. This file system defines how data is stored and accessed on the device. A RAW drive is a drive which is not formatted. The file system cannot be accessed by Windows OS. Therefore, it is unable to mount it as a drive. Since Windows sees no file system or a RAW file system, it prompts you to format the drive.
Reasons for RAW USB drive
The most common reason for USB drives to suddenly become RAW is an unsafe removal of the device. When a USB device is removed without using Safely Remove Hardware, it damages the drive. It can also happen due to a power failure or any problem with the computer that caused temporary USB disconnect.
In order to avoid this situation, always use Safely Remove Hardware. Click on the Safely remove hardware icon in the taskbar, select your USB drive and wait till you get the confirmation message.
