how do i eject flash drives
Safely Removing a Flash Drive. When you insert a flash drive into a computer running Windows 7, 8 or 8.1, an icon reading Safely Remove Hardware and Eject Media displays on the system tray. To unplug your flash drive, right-click that icon, and select Eject USB Flash Drive. If it's safe to eject, a notification displays Safe to Remove Hardware. If instead, the utility notifies you that the flash drive is in use, close any files or applications that you are running off the flash drive, and then try again.
