TL; DR: Onde está meu setor ruim?
Oi,
Eu tenho um disco que falha no seu teste SMART. Há supostamente um setor ruim no LBA 1565541432, mas quando eu tento ler esse setor com dd , o setor parece ler bem. FYI: Eu li o HOWTO dos badblocks e tenho 'consertado' setores ruins nos discos rígidos com sucesso antes, embora eu deva admitir que foi anos atrás.
root@machine:~# dd if=/dev/sde bs=512 skip=1565541432 of=/dev/null count=1
1+0 records in
1+0 records out
512 bytes copied, 0.000114903 s, 4.5 MB/s
Então, parece que esse setor é legível, afinal. Além disso, Current_Pending_Sector é 0 no status SMART. Estou procurando este setor supostamente ruim no lugar errado?
root@machine:~# smartctl -a /dev/sde
