ProDOS doesn't have "invisible files", and a volume copy will copy
the _entire_ content of a volume, including deleted files, so it is not
clear what isn't working.

Some copy protection schemes used allocated space that was not
a part of a file to hold "magic" that the program checked for before
running, but a volume copy should get that, too.  ;-(
