год назад я создавал тред гарантия по кол-ву битых секторов диска
после того треда я сделал зануление в программе mhdd
внезапно все кандидаты на ремап ушли, диск выглядил как новый (не считая проработанного времени)
однако ошибки снова начали повторяться:

вангую что после зануления mhdd все ошибки уйдут
однако, каждый год не хочется форматировать
проблема скорее всего программная, может есть способ исправить?
