I came across a VERY interesting phenomena when I copied the
data of my XP20 hard disk, to a CMS Pro 102k/II internal hard 
disk on a Mac II.  (Note that the XP20 was create and used
originally on a Mac SE).  The resulting two disks, both
having IDENTICAL information on them showed a difference of
over 1 Meg of storage:  XP20 18000K,  CMS 19200K.

The CMS was formatted and initialized before the copy was done, 
and had only  about 32K before the copy began.

I noticed that each folder on the CMS we slightly larger
than the same folder on the XP20.  This eventally added up 
to 1M for all the folders.

What is the reason for this.  Is it the interleave factor,
(I think both are 1:1 - maybe not?  I know the CMS is) or
something different about the CMS hard drive.

 . . I'm very curious whats adding 1Meg per 20Meg of space??
