I just tried it out, INIT/SHADOW/ERASE on two 2-GB disks.  Took about 20 
minutes.  Then I built a shadow set with MOUNT/CONFIRM.  It didn't ask 
me to allow a copy (i.e. it realised the disks were in synch) and the 
shadow set formed immediately, with no merge whatsoever.

Getting back to another thread, the value for maximum files on this 
shadow set is 16711679, the same as on an 8.5-GB disk.  Apparently this 
is related to /LIMIT with no argument, but at least in HELP this doesn't 
seem to be documented.

I'm pretty sure that the shadow set, as it is, couldn't take anywhere 
near that many files.  Perhaps if expanded to the 1-TB limit.  I would 
also like to know where this number comes from.  It is APPROXIMATELY (a 
little less than) 1/128 of a terabyte.
