I have to disagree here. I have several USB disks attached to my
computer, and while I agree that this provides no security against an
attack, it does provide protection against user errors, just as it does
on internal disks. A disk being external does not preclude that several
users access it and want protection from the other guy unintentionally
deleting their files.
