Me pregunto si los resultados de esta autocomprobación SMART indican una unidad defectuosa, esta es la única unidad que aparece con 'completado: falla de lectura' en los resultados.

La unidad aún no muestra signos de falla, aparte de la salida de esa autocomprobación SMART. Esta es la salida de una unidad diferente en el mismo sistema que actualmente ejecuta una autocomprobación SMART

smartctl -a /dev/sde
y publicara la sección etiquetadaSMART Attributes Data Structure
que contiene contadores sin procesar. En particular, el primero esRaw_Read_Error_Rate
cuál es el mejor indicador de "disco defectuoso" (y probablemente será! 0 en su caso).
