che ne dite?

[pennega]

non ci capisco molto
che sintomi ha questo disco?
prova a vedere se riesci ad eseguire un check con il controllo dei blocchi cattivi (badblock opzione -c se non ricordo male)
altrimenti su sito del costruttore dell'hdd dovresti trovare qualche tool per "poterlo" tamponare un pò... io ho recuperato un WD da 2TB con qualche badblock con i tools della WD
