Yes... but think of the advantage of loading 1 or 2k of directory, swaping
around a few lines of information and writing it back out to disk.  Beats
the heck out of copying not only the directory entries, but all the associated
data to another partition and back. (in terms of speed)

If you do it one directory ar a tine, the head won't even have to move more
than one track on an optimized disk.
