ciao
da qualche giorno Freenas mi segnala quanto in oggetto nonostante che ho controllato il disco da windows con chkdsk /f
a cosa è riconducibile questo avviso? è sintomatico di un danno imminente?
grazie
Dario

questi i mie diski: da1 e da2 sono due dischi esterni da 3 TB
da1 è il backup esterno del mio volume, da2 lo uso per memorizzare video di grandi dimensioni (4K o UHD) che poi vedo con Plex

Ciao, dovresti fare un extended self-test sul disco da2: smartctl -t long /dev/da2.

Sebbene l'extended self-test non abbia rilevato errori, il numero di settori rovinati (16) e riallocati (572) superiore a zero, a leggere qui e qui, è un segno che il tuo hard disk da2 sta per tirare le cuoia.
Se è ancora in garanzia potresti fare un RMA e fartene mandare uno nuovo.
