[MontelLUG] Stato di salute di un hard disk

[Odeeno]

A seguito di qualche curiosa sparizione ho fatto un controllo dell'hard
disk e in particolare dei dati SMART.

Il fatto è che non ho grandi conoscenze a riguardo e vorrei sapere se
qualcuno mi sa dare un commento e un consiglio su qualche programma
utile a riguardo.
Tra le varie cose mi pare di capire che non ci siano settori guasti, ma
il resto non lo riesco a interpretare.
