Насколько серьезным должен быть жесткий диск, чтобы получить неподтвержденный статус SMART на Mac

У Seagate Barracuda в моем iMac 2011 года начались сбои жесткого диска.

Однако дисковая утилита и системная информация сообщают о состоянии SMART: проверено

Я извлекаться подробную информацию, используя smartctlиз https://www.smartmontools.org/ :

Это выглядит не очень хорошо: ожидающие, неисправимые сектора, зарегистрированные ошибки.

Вот мне и интересно

1. У меня сломан жесткий диск, что приводит к ошибкам чтения / записи и сбоев файловой системы
2. Атрибуты SMART подтверждают, что диск сломан

Почему мой iMac по-прежнему сообщает о подтвержденном состоянии SMART?
