em poucos meses o HD comecou a dar defeito Realizei testes de diagnóstico com o programa Hard Disk Sentinel (versão completa), que reportou: Status do disco: DEGRADADO Health (saúde): abaixo de 100% com quedas progressivas a cada varredura Indicadores SMART alterados: Reallocated Sectors Count (05) Current Pending Sector Count (C5) Uncorrectable Sector Count (C6) Número de setores realocados / pendentes: centenas, indicando Bad Blocks físicos Temperatura e rotação (RPM): dentro dos limites normais, o que reforça que o defeito é físico na superfície magnética ou no conjunto de leitura/gravação Além disso, o programa Windows CHKDSK e ferramentas de varredura de superfície confirmaram falhas não recuperáveis em múltiplos setores e perda de integridade no sistema de arquivos, impossibilitando o uso do disco para armazenamento confiável.
