As alterações permanecerão apenas na memória, até que você decida gravá-las. Tenha cuidado antes de usar o comando de gravação. A unidade não contém uma tabela de partição conhecida. Criado um novo rótulo de disco DOS com o identificador de disco 0x0125a9ba. Comando (m para ajuda): Tipo da partição p primária (0 primárias, 0 estendidas, 4 livre) e estendida (recipiente para partições lógicas) Selecione (padrão p): Número da partição (1-4, padrão 1): Primeiro setor (2048-134217727, padrão 2048): Último setor, +/-setores ou +/-tamanho{K,M,G,T,P} (2048-134217727, padrão 134217727): Criada uma nova partição 1 do tipo "Linux" e de tamanho 64 GiB. Comando (m para ajuda): A tabela de partição foi alterada. Chamando ioctl() para reler tabela de partição.
