Sprawdziłem ponownie status SMART dysków w moim komputerze. Mam w posiadaniu 2 dyski Barracuda 500MBm jeden z rodziny 7200.11, a drugi 7200.12. Jeden z nich został zwrócony do sklepu na reklamację – nowy posiadał kilka relokowanych sektorów już w pierwszej godzinie użytkowania. Drugi też był reklamowany i wymieniony kilka sektorów pojawiło się także po kilku godzinach od podłączenia.
Obecnie oba pracują ponad rok. Pooniżej zamieszczam wszystkie dane ze smartctl, może ktoś zechce porównać

Ten jak zauważyłem na starcie zaliczył errora, ale trzyma się dzielnie
