[Risolto] HD pre-fail

Ciao a tutti.
il disco del mio Dell Inspiron sembra invecchiato. Non mi da' apparenti performances critiche (forse il pc un po' piu' lento..) ma smartctl mi da la seguente videata

[root@dell11 peppe]# smartctl -a /dev/sda

Mi pare ci sia da aspettarsi qualche problema.
Secondo voi si puo' agire tentando qualche 'riparazione' via comandi del sistema?

Separatamente apro un nuovo topic su come riportare dati e applicazioni dalla vecchia macchina su un eventuale nuovo pc

Re: [Risolto] HD pre-fail

Da dove lo deduci che si stia rompendo? Se ti riferisci al valore del campo n. 7, è tutto normale:

>>> (202308734 & 0xFFFF00000000) >> 32
0

I problemi hardware si risolvono riparando/cambiando l'hardware: se un hard disk invecchia non si può riparare via software.

Re: [Risolto] HD pre-fail

In questa parte mi da' segnali che interpreto come test interrotti ad un certo valore di LBA (che e' sempre quello).
Sbaglio a leggere?

Un settore danneggiato. Fai sempre il backup e procedi tranquillo finché si tratta di un singolo settore.

Re: [Risolto] HD pre-fail

Scandagliando il web ho visto il comando

# badblocks -v -s /dev/sdax

con x=1,2,....
Da live, dato questo comando su tutte le partizioni, mi trova 4 blocchi danneggiati successivi sulla partizione sda5 che e' quella di /swap.
Le posizioni coincidono con quelle trovate da smartctl (che trova solo il primo difettoso e poi si ferma).
Le altre partizioni sono ok.

Forse usi molto la swap? smile
