missing eject button

I was missing my eject button in the menu bar for my mac. This was causing me problems because I don't have a mac keyboard on it and so, if theres no cd in the drive, I had limited options for getting the drive open. Then I found out how to return the eject icon to my finder toolbar:

open /System/Library/CoreServices/Menu\ Extras/Eject.menu

or, if you want to use the finder, open a finder window, click cmd-shift-g and type

/System/Library/CoreServices/Menu Extras/

hit enter, and then double-click the Eject icon.

sweet!
