In my installation there is no Safe Remove icon in the system tray. It is not hidden, simply there is no such icon. (I checked in "Notifications & actions" and there is no such icon in the list, and even switched on "Always show all icons...",) no traces...
I have two USB drives plugged in... Both drive's policy is set to "Best performance" and not "Quick removal"
There is no eject in the context menu when I right click on them.
