When most disk packers "optimize a disk" they go through the the Volume Bit Map
and look for *all* the blocks that are marked as "not in use", then they
fill the unused blocks with $00s.  This removes the remnants of any deleted
files and allows the disk to pack up smaller.  There's no reason to do this
on your hard disk.  It won't improve its performance any.

If you get me a domain-based address, Heiko, I'll see if I can scratch up a
copy of the DDD Pro docs for you.  (mumblefoo.UUCP is NOT a domain address...
mumblefoo.baz.com is.)
