При копировании директории с большим количеством файлов (суммарно порядка 10 Гб) на раздел с системой ntfs наблюдаются сообщения об ошибках создания целевого файла.
Так, Mignight Commander выводит сообщение: "Невозможно записать целевой файл, ошибка ввода-вывода (5), Пропустить, Повторить, Прервать". Если нажать "Повторить", то процесс копирования продолжается. Файлы, на которых возникают ошибки каждый раз разные; после нажатия "повторить" копируется нормально.
При копировании через команду "cp" возникает похожая ситуация, разве что только выводится информация об ошибке без запроса "что делать?".
При выполнении такого же копирования на другой раздел ntfs другого жёсткого диска ошибок не возникает.
В выводе dmesg какой-либо информации о ошибке я не обнаружил.
Подозревая, что дело в жёстком диске, я запустил на ночь badblocks через cron:
/sbin/badblocks -n -o /home/roman/badblocks_sdb.out /dev/sdb > /home/roman/badblocks_sdb.report.txt
После окончания проверки оба файла были пусты, из чего я сделал вывод, что битые секторы не обнаружены.
Далее решил посмотреть, что выводит smartctl -a /dev/sdb

Судя по таблице значений атрибутов всё в норме, единственное, что смущает, так это список последних ошибок типа "Error: ICRC, ABRT 34 sectors at LBA = 0x002c4425 = 2901029"
