Dúvida S.M.A.R.T. - Western Digital Elements

Boas.

Andei a ver no site da Western Digital para tentar perceber se os WD Elements têm suporte para S.M.A.R.T. e não consigo encontrar nada lá.

Alguém sabe se estes discos têm ou não esta feature?

O meu disco é um WD Elements 2TB (WDBU6Y0020BBK-0A).
 
ptfuzi disse:
Isso depende da controladora. Visto que os discos têm sempre..
Se correres software que lê o SMART dá erro?

Têm sempre? Não tenho assim tanta certeza.
Eu estou em Linux e a aplicação que uso para ler dados devolvidos pelo S.M.A.R.T. diz que não está disponível.

SMART todos têm.
Podes tentar usar o Data Lifeguard da WD para ver o estado do disco: https://support.wdc.com/downloads.aspx?lang=en

Isso não deve funcionar em Linux, pois não?
 
O problema é ser uma unidade USB. Nem todas passam a informação S.M.A.R.T. em modo standard. O mais certo é utilizarem algum protocolo proprietário só acessível com a utilidade do fabricante.

Num dos screenshots dele, tens a informação SMART.

Já consegui com osmartmontools aka smarctl. No entanto, como acho que já foi dito, parece haver alguns problemas relativos à forma como drives externas ligadas por USB são vistas pelos OS's. Como há alguma incompatibilidade entre o que é necessário ser visto pelos OS's para que os comandos S.M.A.R.T. possam ser executados (interpretados e os resultados lidos e mostrados), e o que realmente o SO vê, existem limitações ao que pode ser reportado por estas drives ligadas por USB.

As for USB and FireWire (IEEE 1394) disks and tape drives, the news is not good. They appear to the operating system as SCSI devices but their implementations do not usually support those SCSI commands needed by smartmontools. A consortium associated with IEEE 1394 certified some external enclosures (containing a ATA disk and a protocol bridge) as being compliant to the relevant standards. Even still, that compliance means that they tend to only support the bare minimum of commands needed for device operation (i.e. SMART support is an unsupported extra). Hopefully external USB and Firewire devices will support SAT in the future, see below. Some USB device based on cypress chips support a proprietary protocol (ATACB) that allow to send raw ATA commands (i.e. SMART support).

Ainda cheguei a instalar esse mas depois fui pesuisar um pouco mais sobre o smartmontools e acabei por conseguir ao "forçar" o smartctl a usar a opção "-d sat".
