“Probably you might ask yourself why you need it?! The matter of
privacy today is very sensitive and as such sometimes we may need
additional measures when our security might be compromised. Good
examples of Truecrypt usage are protection of sensitive business or
personal data, valuable pictures or movies you would not like to be
expose to anybody else, I have read that some people hide their
whole OS under Truesrypt so that nobody could activate it without
them. You could encrypt whole USB device so when you lose it nobody
could use or manipulate your data on it etc. Endless possibilities
which let you sleep tight. :)”
