Acabei de trabalhar com o comando umount
Eu tenho um disco rígido externo de 3 TB que eu tenho formatado para ext4 usando o gparted. Agora, quando eu o conecto ao meu laptop, o ubuntu não o detecta. Esta é a saída do fdisk
sudo fdisk -l

Há algo que eu possa fazer para consertar isso de alguma forma?
