Auto Eject Flash drive at Logout

Question

I work in a computer lab at my college and one of the common issues we have is people leaving their flash drives behind. I want to create a script/automation that will upon logout display a window reminding the user to remove their flash drive.
Any ideas as to what the best way to approach this is? (Automator/AppleScript/Etc.)
And where to begin?

Answer 1

how about this:
paste the following into Script Editor and save it as an application
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #ADD8E6;
overflow: auto;"
title="this text can be pasted into the Script Editor">
tell application "Finder"
if number of disks > 6 then display dialog "please remove your flash drive"
end tell</pre>
Instead of 6 put the number of disks you normally have on that computer. save it as an application somewhere. then make a logout hook to run this app on logout.
to do that run the following terminal command
sudo defaults write com.apple.loginwindow LogoutHook /path/to/app/you/made
put the path you've just made in the above.
