De vez em quando, meus HDDs (6 drives de 1TB em um array Linux md RAID-6) fazem um breve som de "click", e eu recebo isso de dmesg . Eu realmente não tenho idéia de como começar a diagnosticar isso, ou até mesmo como isso é sério. Eu posso fornecer qualquer outra informação que possa ajudar.

O comportamento que você está enfrentando parece ser o desligamento das unidades do sistema, reconectando-se quando o sistema reinicializa o link SATA.
Você pode querer certificar-se de que seus cabos não estejam danificados, limpos e adequadamente encaixados nas portas e unidades da placa-mãe. Se isso não ajudar, pode ser um bug no sistema operacional ou um problema com o controlador SATA.
