Estou tentando formatar um disco, mas seja o que for que eu tente depois de uma reinicialização, a partição antiga está sempre lá.
Eu tentei ver a partição com fdisk e formatar novamente usando mkfs.ext4
mirto@mirto-C35:~$ sudo fdisk /dev/sdb
Welcome to fdisk (util-linux 2.31.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
