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.
