Do S.M.A.R.T. testes desgastam o disco rígido?

Question

Eu queria saber, é seguro fazer um teste inteligente "estendido" em um disco rígido de 1 TB regularmente (uma vez por mês)?

o que dizer de "curto" e "transporte"

    

Answer 1

Sim, embora marginalmente. Qualquer ação que resulte em movimento mecânico é uma ação que está ajudando o sistema a morrer. Hooray para Entropy . Aquilo que não te mata só te aproxima da morte ...

Lembre-se, porém, que o disco está continuamente acumulando estatísticas, portanto basta olhar para as estatísticas para saber se o disco está saudável o suficiente para executar o teste.

Aqui estão algumas informações sobre o que envolve cada nível de teste (referências de notas de rodapé removidas): link

SMART drives may offer a number of self-tests:

Short Checks the electrical and mechanical performance as well as the read performance of the disk. Electrical tests might include a test of buffer RAM, a read/write circuitry test, or a test of the read/write head elements. Mechanical test includes seeking and servo on data tracks. Scans small parts of the drive's surface (area is vendor-specific and there is a time limit on the test). Checks the list of pending sectors that may have read errors, and it usually takes under two minutes.

Long/extended A longer and more thorough version of the short self-test, scanning the entire disk surface with no time limit. This test usually takes several hours, depending on the read/write speed of the drive and its size.

Conveyance Intended as a quick test to identify damage incurred during transporting of the device from the drive manufacturer to the computer manufacturer. Only available on ATA drives, and it usually takes several minutes.

Selective Some drives allow selective self-tests of just a part of the surface. > The self-test logs for SCSI and ATA drives are slightly different. It is possible for the long test to pass even if the short test fails.

The drive's self-test log can contain up to 21 read-only entries. When the log is filled, old entries are removed.

Para responder à sua pergunta, executar um teste estendido periodicamente não causará muitos problemas desnecessários. No entanto, está colocando um desgaste em partes da unidade sem nenhuma razão real. Eu colocaria o tempo e o esforço em uma solução de backup frequente, em vez de fazer testes frequentes na unidade.
