Before disconnecting a USB storage device, make sure your computer has finished transferring
data to that device. Click the Safely Remove Hardware and Eject Media icon in the Windows
notification area to remove the device before disconnecting.

automatically. However, some devices may require you to install the driver before connecting.
Check the documentation provided by the device’s manufacturer before connecting the device.
