Without hacking at XS, I don't know there is a way to know if a given disk
is in the floppy drive, but you can get all the mounted volumes:

  @volumes = MacPerl::Volumes;

That gives the FSSpec for each.  To get paths:

  @volumes = map {MacPerl::MakePath($_)} MacPerl::Volumes;

If you want to detect a change, you can do:

  #!perl -w
  %volumes = map {(MacPerl::MakePath($_), 1)} MacPerl::Volumes;
  CHECK: while (sleep(1)) {
    my @volumes = map {MacPerl::MakePath($_)} MacPerl::Volumes;
    foreach my $vol (@volumes) {
       if (!exists($volumes{$vol})) {
         print "$vol !\n";
         last CHECK;
       }
    }
  }
