If you see  RAW next to the drive size at the bottom (and under  File System in the top pane), it means Windows doesn’t recognize the drive’s file system.

In some cases, this indicates that the drive is formatted with a macOS or Linux file system that Windows cannot use.

Right-click on your USB drive (make sure you choose the correct one) and select  Format. You will see an interface similar to the one you used before.

Select the Volume label, specify the File system  (FAT32 is best for smaller devices or devices you plan to use across platforms), and leave the Allocation unit size as  Default.

If this fails, you can try the Delete Volume option in the drive’s right-click menu. Deleting a volume will erase everything Windows has assigned to disk, leaving only unallocated space.

Therefore, you need to create a new volume by right-clicking it, selecting  New Simple Volume, and following the steps (which are similar to other formatting methods).
