These two questions are discussed so frequently on this and other lists
that you should be able to get numerous explanations with a small
search on Google and I would be surprised if there were not a FAQ on

Basically, du and df look a slightly different things and there is
a difference between how much root and regular users are allowed to
write to a filesystem.
