Você quer saber como ver informações com detalhes de um disco em seu pc que usa Linux? Veja esse post como obter essas informações usando hdparm.
O hdparm é um utilitário de linha de comando, um programa, que permite ajustar opções de desempenho e gerenciamento de energia dos discos rígidos (HDs) em sistemas Linux. Podemos testar a taxa de leitura, ativar otimizações para o HD, entre outras funcionalidades.
Mas nesse post iremos usar hdparm para exibir informações relevantes do disco, como qual o modelo, número serial…
Para executar hdparm, basta digitarmos no terminal linux “hdparm nome_dispositivo”, veja:
maria@ti:~$ sudo hdparm /dev/sda1 /dev/sda1: multcount = 0 (off) IO_support = 1 (32-bit) readonly = 0 (off) readahead = 256 (on) geometry = 29186/255/63, sectors = 468871042, start = 204
Com o comando acima tenho poucas informações. Se quiser obter com mais verbosidade posso adicionar -I. A opção -I exibe informações de identificação solicitando essas informações diretamente do disco, então, passamos a ter informações consideravelmente mais detalhadas do que com se apenas usássemos -i.
maria@ti:~$ sudo hdparm -I /dev/sda1
