    Actually it appears that it is using a CBC, there appears to be a middle layer that arbitrarily partitions sections that are encrypted and decrypted on the fly. I was pretty skeptical the last time this was mentioned on slashdot, but I have to admit this actually looks like a promising product. I'll wait for some more skillful security experts to evaluate it first, but I'm certainly keeping an open mind on it.

    Most good hard disk encryption technologies behave in way that if a single bit is flipped in an encrypted sector, then the whole decrypted sector becomes corrupted (and others sectors around this one are not affected). This sort of behavior is desired and help prevent content leak attacks.

    For example, Loop-AES behaves like this in multi-key-v3 mode where CBC is used with an IV computed from a secret key, the sector number, and plaintext blocks [1..n-1] in the sector. This is also how Microsoft Bitlocker behaves because they combine CBC with the Elephant diffuser. When CBC is not used, this property can be achieved using LRW or XEX, or wide-block encryption.
