Итак, когда вы выполняете полный fsck на жестком диске, чтобы найти плохие блоки, игнорирует ли он или освобождает это пространство на диске, куда он помещает (перераспределяет) плохие блоки?
Я говорю о пространстве, подразумеваемом атрибутами SMART:
196 Reallocated_Event_Count
а также
5 Reallocated_Sector_Ct .
Я спрашиваю, потому что, когда я бегу:
# smartctl -a /dev/sda
Я получаю следующий вывод:
smartctl 5.41 2011-06-09 r3365 [x86_64-linux-3.2.0-40-generic] (local build)

Меня беспокоит необработанное значение атрибута 196 Reallocated_Event_Count , и я планирую запустить ночью fsck в /dev/sda чтобы проверить, действительно ли у меня есть плохие блоки.
Заранее спасибо!
