After your system reads the USB drive go to Device Manager.

In Device Manager Check for Disk Drivers, there you can find your USB driver name right click on it and select Properties.

After completing the above steps right click on the USB and select Format.

Before finalizing for format, click on the File system and select NTFS and click on Start in the format window.

Once you’re done with formatting your USB drive with NTFS file system. Now you have to configure your USB drive root to read-only in the security permissions.

Open computer and right click on the USB and select Properties.
