How exactly can a program, the system, etc. tell the difference between
two floppies. If I take floppy (ok, firm) disk A and call it 'Blah', an d
insert it into my only internal firm drive, then hit shift-cmd-1 and proceed
to insert firm disk B, also named 'Blah' - the system will create
a new icon on the desktop and leave disk A's icon greyed... and when
I insert A back in, it highlights A's original icon... So the question is:
What information is it reading to discern the difference,
Where is this stored,
and Which textual references can I find on this?
(Inside Apple, etc?)...
Thanks to all in advance...

The technique I always recommend is to remember the volume's name and creation date. I seem to recall that the Alias Manager for System 7.0 saves that information along with the size of the volume. -- ------------------------------------------------------------------------------ Keith Rollin --- Apple Computer, Inc. --- Developer Technical Support INTERNET: keith@apple.com UUCP: {decwrl, hoptoad, nsc, sun, amdahl}!apple!keith "Argue for your Apple, and sure enough, it's yours" - Keith Rollin, Contusions
