Ha tutta l'aria di un problema hardware. Probabilmente in dmesg, avrai una serie di messaggi del kernel che ti dicono il tipo di problema. Al 99% la soluzione e' un disco nuovo.

In teoria potresti riformattarlo e usare fsck.ext? con l'opzione -c (che segna i badblock in modo da non usarli), ma solo se ti senti molto fortunato.

Ciao,
  Diego.
