Eu tenho um sistema FreeBSD com partições acima e ponto de montagem. A partição 7 é uma partição bruta que estou tentando formatar com um novo sistema de arquivos, mas estou não capaz de. Eu tentei ext2, bem como os formatos do sistema de arquivos msdosfs.

Atualização 1: recebo o erro abaixo ao formatar com o ext2:

Preciso lidar com um disco rígido de tamanho de setor de 4k de maneira diferente?

Hoje consegui formatar a unidade com msdosfs:
