1. Connect the USB drive to the computer

2. Press the Windows Key ()+ E

3. Click This PC (Windows 10 and newer) 

The USB drive will be listed under Devices and Drives in Windows 10. In older version of Windows, the USB drive will be listed under Devices with Removable Storage.      

Try the steps below if the USB drive does not appear as a drive in Windows or appears as an "unknown device" in the Windows Device Manager. 

Ensure the USB port is Working Properly:

• Try a different USB port on your computer and/or test the USB port with a different USB device
• Avoid connecting through a USB hub, USB extension cable, keyboard, or monitor
• On desktop computers, use the USB ports on the back of your computer
