Hi Doug,
Lean over close to the front of the machine and whisper very gently that you
are now going to remove its thumb. Then, firmly grasp the drive and remove
it from the slot in one sweeping motion. The machine may protest, but in all
fairness you did warn it......
Ok, seriously now, simply open Windows Explorer and right click the drive.
You will find an option in the context menu for "Safely Remove". This will
accomplish the same thing, which is basically to ensure that the system
stops writing to the drive.
Not sure why it isn't showing in the system tray, but you might try checking
that a) the system tray icons are fully expanded and b) that it has not
become an 'aged' icon in the taskbar and start menu properties.
