Размонтирования USB 3.0 ExternalEnclosure наугад

В заголовке говорится все это.

Я заметил, что диск был размонтирован, таким образом, я добрался до просмотра dmesg и нашел:

После a

mount -a

Я нашел следующее в dmesg

[31524.944795] usb 4-3: reset SuperSpeed USB device number 4 using xhci_hcd
[31524.960309] usb 4-3: Parent hub missing LPM exit latency info.  Power management will be impacted.

[31525.813172] EXT4-fs (sdc1): recovery complete
[31525.813499] EXT4-fs (sdc1): mounted filesystem with ordered data mode. Opts: (null)

Кроме того, я записал сценарий крона для записи во внешнее поле каждую секунду (только с касанием), потому что я не мог заставить управление питанием не вращать вниз диски. Который выстраивается в линию с тем, каков вывод dmesg.

Любая справка значительно ценилась бы!Спасибо!
