Classic OS 9.2 - Hide Icons

I am trying to find if there is a way to hide the harddrive and the cd-rom drive when they pop up? I have a preschool and the kids keep asking if they can play the demos on the cd-rom but I don't want them to play them. Is there a program that can be installed or an existing feature in Classic 9 that I am unaware of? I know that it is really easy to do in OS X but I don't know how to do it in Classic.

Thanks for the help.

Hey... I'm sorry to tell you that there isnt a way to do that however you can drag those icons to the verybottom and hide them the best you can... thats really all.

No Software

No one ever created some sort of program that hides them in classic? Anything would be helpful

You create a black jpeg like 70 pexels and replace the icon photo. Put the black square in the clip board. Highlite the HD icon open. In the OS9 file menu under get info you will see the icon in the top window. Click on it... pull down edit and paste. Black square is now the icon. Dont know if this works in classic with a OSX desktop.
