Can you try this? I wrote this sub:

####################################################################
#
# This function returns a list of logical drives in Windows.
# Each list element starts with drive letter, followed by
# drive type, serial number, file system, label, total space
# and free space. All items will be separated by a '*' character.
#
# If one or more letters are provided as an argument,
# then data will be returned only about those drives.
# Example:
#   GetDriveInfo('CE') => Returns data about drive C: and E:
# If drive E: does not exist, then it will be left
# out of the list!
#
# Usage: STRING = GetDriveInfo([DRIVEs])
#
sub GetDriveInfo
{
  my $DRIVES = defined $_[0] ? $_[0] : 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
  return RunJS("V='$DRIVES';try{FSO=new ActiveXObject('Scripting.FileS
+ystemObject');}catch(e){WScript.Quit(0);}A=[];function ToHex(N){N|=0;
+var i,X='';for(i=0;i<32;i+=4)X='0123456789ABCDEF'.charAt((N>>i)&15)+X
+;return X;}for(i=0;i<V.length;i++){L=V.charAt(i)+':';if(FSO.DriveExis
+ts(L)){D=FSO.GetDrive(L);if(D.IsReady){S=ToHex(D.SerialNumber)+'*'+D.
+FileSystem+'*'+D.VolumeName+'*'+D.TotalSize+'*'+D.FreeSpace;}A.push(L
++'*'+D.DriveType+'*'+S);}}WScript.StdOut.WriteLine(A.join(\"\\r\\n\")
+);");
}


#
# Usage: INTEGER = RunJS(JSCODE)
#
sub RunJS
{
  no warnings;
  $^O =~ m/MSWIN/i && defined $_[0] && length($_[0]) or return 0;
  mkdir "C:\\TEMP";
  my $TEMPFILE = "C:\\TEMP\\JSTMP001.JS";
  my $CSCRIPT = "C:\\WINDOWS\\SYSTEM32\\CSCRIPT.EXE";
  -f $CSCRIPT or return 0;
  local *FILE;
  open(FILE, ">$TEMPFILE") or return 0;
  binmode FILE;
  print FILE $_[0];
  close FILE;
  -f $TEMPFILE && -s $TEMPFILE == length($_[0]) or return 0;
  my $E = system("$CSCRIPT //NOLOGO $TEMPFILE");
  unlink $TEMPFILE;
  return $E + 1;
