Portanto, tenho duas unidades no meu computador, uma unidade de disco rígido (Seagate Barracuda ST2000DM001) e uma unidade SSD (Corsair Force 3 de 120 GB). Eles são ambos de 3 anos e eu pensei que eles deveriam durar muito mais tempo, especialmente o disco rígido. Embora eu admita que meu computador tenha problemas por algum tempo com desligamentos bruscos por causa de problemas com a PSU.
Mas quando eu verifiquei os dados SMART, eles têm "Pré-falha" em alguns campos. Agora eu sei que nem todos os campos são tão importantes, mas eu tive dificuldade em encontrar interpretações corretas (especialmente para o SSD).
Além disso, o HDD parece falhar nos autotestes. Eu tentei com vários programas, incluindo a ferramenta Seatools da Seagate e o smartctl (Bash).
Então, aqui estão as perguntas: Quão séria é a situação real? As unidades realmente podem falhar? Em caso afirmativo, devo apenas fazer backups e esperar que isso aconteça ou é melhor substituí-los completamente o mais rápido possível?
Obrigado pelo seu tempo

Essa é a coluna "Tipo". Ele não indica um status de qualquer tipo, mas sim se a degradação de um atributo é normal (desde a idade avançada) ou um indicador de falha iminente.
Dito isto, o seu HDD está claramente prestes a desaparecer. Ele tem uma grande quantidade de setores realocados, indicando danos à superfície.
