Невозможно обнаружить жесткий диск Seagate 2 ТБ на Dell Vostro 3480

После того, как я постоянно сталкивался с проблемами с обновлениями Windows 10, я решил перейти на Ubuntu 18.04 LTS, так как я немного знаком с Ubuntu. Однако после успешной установки Ubuntu 18.04 LTS я столкнулся с проблемой, связанной с обнаружением внешнего жесткого диска Seagate в Ubuntu.

Обыскав каждый форум и попробовав все, что они предлагали (в частности, эту ветку: Внешний жесткий диск Seagate 2T не может быть смонтирован, он обнаружен lsusb, но не fdisk -l ), я все еще не могу чтобы мой жесткий диск был обнаружен.

Мой терминальный вывод команд, приведенных в вышеупомянутом потоке, выглядит следующим образом:
