I have to disagree here.  While this type of balancing is a Good Thing, it
won't actually have much effect on fragmentation.  Fragmentation usually
occurs when files are built, purged, built, purged etc. with "holes" being
created throughout the disk.  This will still happen regardless of where
the initial files are allocated.  What will happen with Wirt's suggestion
is that disk allocation will be evenly balanced between drives of unlike
sizes.  Again, this is a Good Thing.
