Anatomia upadku hdd

Witam,

Znajomi przynieśli mi laptopa z płaczem, że się zawiesił i nie uruchamia
się, pisząc, że brakuje jakiegoś pliku.
Po przeskanowaniu okazało się, że ma 129GB błędnych sektorów na 500GB
pojemności.
Błędy są rozłożone w 24 obszarach w miarę symetrycznych.

Jaki mógłby być mechanizm takiego zaorania dysku?
Ludzie twierdzą, że wcześniej nie było jakichkolwiek objawów, laptop nie
uczył się latać, uszkodzenie nie wydaje się też rozszerzać.
