Premetto che il disco lavora da 3 anni, continuativamente senza
apparenti problemi, come disco di sistema di un server Debian.
Ho fatto una verifica con smartctl su un disco (un economico
2.5" non recente), lanciando anche un test.
I dati che ci sono nella maschera tuttavia mi sembrano
o non significativi o terrificanti.
Su altri dischi, come quello del mio portatile, ottengo invece
risultati molto piu' intuitivi e tranquillizzanti.
Devo quindi stare preoccupato perche' il disco sta morendo,
o perche smart non vede e non vedra' mai niente?
Ciao e grazie. Marco
