In old version of parted like parted-2.1-25, error message is shown in
stdout when printing a disk info without disk label.
Error: /dev/sda: unrecognised disk label
This line has been moved to stderr in newer version of parted. So we
should check both stdout and stderr when locating this message.
This should fix bug:
