A sense of their own self-importance?  No-one cares that much, except 
ego-charged management types.  Really.

After the disk has been overwritten *once*, the data can not be 
recovered without extremely specialised tools.  Write a suitably random 
pattern over the whole disk a couple of times, and it is gone.  Utterly 
gone.  No amount of prodding with electron microscopes will bring it back.
