What is a RAW drive format?

A RAW drive or disk is a disk/drive with a RAW file system, which cannot be recognized by Windows operating system like FAT32, exFAT or NTFS file systems. This means all the available file system drivers refuses to mount the file system. Since no recognizable file system exists on the hard drive, you will be unable to access the drive, not to mention, to access the files or folder within it.

Why need a USB RAW format tool?

The “RAW” file system issue usually occurs when the file system type information is lost, or the file system table gets damaged. This issue is often associated with unplugging without “Safely removing them” first. Generally, when you get a RAW USB flash drive, then there are chances that you will meet the following issues:

1. Windows prompts an error message saying "You need to format the disk in drive E: before you can use it. Do you want to format it?" when you try to open the USB drive in Windows Explorer.

2. In the drive properties Window, you will find the USB flash drive showing 0 bytes in both used space and free space.
