Po zainstalowaniu nowej wersji fedory (11), za każdym razem po
uruchomieniu systemu dostaję komunikat o błędzie dysku(z programu
Palimpsest Disk Utility 0.3). w detalach przy jednym parametrze jest
FAILING

1 Read Error Rate current: 200 worst: 1 threshold: 51 value: 0 status:
FAILING type: pre-fail updates: online

Reszta parametrów jest ok. Co oznacza ten błąd? Czy powinienem się
martwić i szykować kasę na nowy dysk? Czy to jeszcze nic strasznego?
Załączam poniżej wynik programu smartctl --all /dev/sdb. Wyświetla on
kilka informacji o błędach, czy dobrze rozumiem że wystąpiły one dawno
temu (at disk power-on lifetime: 840 hours)?

Oznacza, że w jakimś momencie pracy dysku wystąpiło sporo
błędów odczytu. Trudno dociekać przyczyny, mogło to być na-
trafienie przez dysk na uszkodzony obszar (wyłączony potem
z użycia). Wskaźnik jednak wrócił do normalnej wartości,
więc dysk nie jest "umierający". Warto na pewno poobserwo-
wać, czy ta wartość znowu nie będzie spadać (im mniej, tym
gorzej) i jak zwykle warto mieć kopię zapasową danych, ale
nie ma raczej powodu do paniki.

Dzięki za pomoc:) czegoś takiego się spodziewałem, ale nie byłem pewien.
