Re:not good for encryption, but (Score 1)

hmmn.. there used to be a lame way to "protect" in DOS by formatting a disk using some different allocation size (something odd). It could only be read if you knew what settings you used. I don't remember the details since this was pre-winblows. (anyone care to fill me in?).
This is kinda similar to inadequate encryption that is hyped to solve such problems. Anything less than 128-bit encryption is not really secure w.r.t FBI/whoever.
