No, that wasn't my problem! The system  *can* tell the files apart even  if I
do use the same pathnames for different disks. An example: I use disk 1 named
"Disk" and  a  function  from  lisp  to  access  files  on  that  disk  (e.g.
directory). Then I  put in  another disk  also named  "Disk" and  try another
file-access. Now the macsystem pops up 'please insert disk "Disk"'.

The system distinguishes between the  disk by the volume  ID, but I just  can
access them by pathname (there's just the function 'do-mac-volumes who  knows
something about volume IDs)

Since I already  had a  very different  solution for  my problem,  it doesn't
touch me any more. But  I think that's a  general problem of connecting  two
very different models of file-systems.
