Ubuntu 16.10. внешний ntfs-3g жесткий диск извлекается случайным образом в течение ночи

⇒ uname-a Linux nortrom 4.8.0-41-универсальный # SMP с 44 Ubuntu пятница 3 марта 15:27:17 GNU/Linux UTC 2017 x86_64 x86_64 x86_64

Сегодня я осознал свой внешний жесткий диск моей человечности homeserver быть выключенным, несмотря на активные загрузки, которые должны были использовать жесткий диск.

Это соединено через USB3.0 и смонтировано с ntfs-3g.

это - мой fstab:

Вот отрывок системного журнала, я думаю, содержит релевантную информацию:

отдых является чрезвычайно высоким количеством массово разосланных записей, это отказавший ntfs_read.

После этого инцидента я не мог повторно смонтировать диск, поскольку это больше не появлялось в/dev/. Даже повторное подключение USB-кабеля не помогло. Светодиод HDD устройства был выключен. Я должен был перезагрузить машину для получения его работающий снова.

Вопрос, что вызвало это? Как я могу избежать его в будущем? Вам нужна дополнительная информация?
