Плохая магия: io manager magic bad!

Вообщем столкнулся с ситуацией полетевшей ФС. В этот раз fsck не помог. Копирование всего /dev/sda на /dev/sdb - не помогает. Копируется только sda1, а когда доходит до sda2 - то весь диск sda пропадает, и появляется только после ребута. Танцы с бекапами суперблоков также не увенчались результатом. После команды ниже - опять пропадает sda.

Superblock needs_recovery flag is clear, but journal has data.

Recovery flag not set in backup superblock, so running journal anyway.
