In this paper we present a group of statistical tests that explore the random behavior of
encryption modes of operations, when used in disk encryption applications. The results of
these tests help us to better understand how these modes work. We tested ten modes of
operations with the presented statistical tests, five of the narrow-block type and the other five
of the wide-block type. Our analysis shows some weakness in some of these modes.
