Ошибки при работе с жёстким диском

[lex4051]

Доброго времени суток.
Использую Debian Lenny amd64.
Жёсткий диск Samsung 501LJ [/dev/sda].
Файловая система ext3 (на весь жёсткий диск [/dev/sda1]).
До некоторого времени работало всё хорошо. Потом были проблемы с бэдблоками. Решил их с помощью mhdd полным стиранием диска (ремап не помог). Потом всё работало нормально в течение трёх месяцев (жёсткий диск используется для хранение фильмов-видео и подобного контента). Сегодня появилась ошибка

Проверял mhdd, потом делал fsck. Он нашёл какие-то ошибки, поисправлял. Пару минут диск работал нормально, пока я не начал считывать файлы, которые были повреждены. Тогда снова появилась эта ошибка. Подскажите пожалуйста как решить эту проблему. Форматировать не желательно.

я так понимаю что бэдблоки расползаются по поверхности всего винчестера.
Решить эту проблему можно заменой самого винта.
Доставайте данные которые ещё целые, хранить что-либо на таком харде нецелесообразно и даже, как вы уже поняли, опасно, может привести к их потере.

Пока что он примонтирован ro. Так что вероятность потери данных немного ниже. Буду их копировать... Но всё-же кроме замены жёсткого диска что бы вы мне посоветовали?

Поставил тест на бэд блоки в fsck [fsck.ext3 -c /dev/sda1]. В итоге, на 0,88% оно застряло.

Попробуйте ещё прогнать badblocks

Так я его запустил вечером. За 7-8 часов на пол процента продвинулось. Жду вот.
При чём при проверке постоянно вылазит та ошибка в dmesg.

[lex4051]

Сам не понял почему, но оно заработало.
В биосе включил AHCI (вместо IDE). С 3 раза получилось запустить
# fsck.ext3 -c /dev/sda1
Оно проверило, что-то наисправляло и оно работает.
Буду рад, если кто-нибудь объяснит в чём было дело.

Давайте посмотрим, что smart скажет.
smartctl --all /dev/<your_disk>
