Buongiorno a tutti,
temo che un disco stia partendo:

Leggendo in giro si suggerisce di sovrascrivere il settore danneggiato
(LBA_of_first_error/8 = 208595) con dd. 208595 è il settore giusto? Nel
mio caso il disco fa parte di un array. Si procede allo stesso modo?
Perché ho provato un paio di volte ma il problema rimane (chissà cosa ho
cancellato!)
Il settore 208595 corrisponde ad un'immagine che apro tranquillamente.
A parte gli errori dei test, non ci sono altri problemi.

L'unico parametro non a norma sembra essere Multi_Zone_Error_Rate, che
però non sembra critico:
"Although this parameter is not considered critical by the most hardware
vendors, degradation of this parameter may indicate electromechanical
problems of the disk. Regular backup is recommended. If no other
(critical) parameters report a problem, hardware replacement is
recommended on mission critical systems only."
Ho già comprato il disco sostitutivo, ma volevo prima vedere se si
poteva fare qualcosa.
Grazie
Mattia
