	This depends how big your files are.  For a typical file say 10k
	in size, I could not see any speed improment.

	Disk Optimizer takes about 5-10 min to reorganize an 10M HD (I
	also have 640K RAM) for an 20M HD, just double to time, I assume.

	I heard there's one call HARDDOG (sp?).  I don't have my hands
	on it yet so I couldn't tell you how good it is.
