Or you could avoid ifs and whiles completely: 
use strict;
use warnings;

use Parse::RecDescent ();

my $grammar = <<'__END_OF_GRAMMAR__';

{
   use strict;
   use warnings;

   sub dequote {
      local $_ = @_ ? $_[0] : $_;
      s/^"//;
      s/"$//;
      s/\\(.)/$1/sg;
      return $_;
   }
}

parse   : record(s?) /\Z/
          { [ map @$_, @{$item[1]} ] }

record  : 'instance' 'of' 'Win32_LogicalDisk' '{' field(s?) '}' ';'
          {
             my $name;
             my %record;

             %record = map @$_, @{$item[5]};
             $name = delete($record{Name});
             
             $name ? [ $name, \%record ] : undef
          }

field   : key '=' val ';'
          { [ $item[1], $item[3] ] }

key     : IDENT
val     : QSTRING

IDENT   : /\w+/
QSTRING : /"(?:[^\\"]|\\.)*"/ { dequote($item[1]) }  # guessing.

__END_OF_GRAMMAR__

my $p = Parse::RecDescent->new($grammar)
or die("Bad grammar\n");

my $text; { local $/; $text = <DATA>; }

my $data = $p->parse($text)
or die("Bad data\n");

require Data::Dumper;
print(Data::Dumper::Dumper($data));
