We have alot of different tools in our software archive.  One that I 
might think is a good addition is some kind of disk wiping tool.  Many 
students replace computers, for whatever reason, but I doubt that many 
give much thought to wiping the disks to fully remove their personal 
information.  Some kind of simple tool that would do that -- writing 
over the hard drive to some accepted standard -- might be a useful 
addition to the archive.   It would have to be promoted properly -- "Use 
this ONLY if you are giving away, throwing away, or otherwise disposing 
of your computer. Once you use this whatever was on your computer is 
GONE GONE GONE!!!"  In an era of identity theft, ect. this might save 
students alot of trouble and, frankly, potential embarrassment by 
preventing their emails, personal photos, etc from ending up in the 
public domain somewhere.
