Mám disk, kde už asi rok mám hodnotu:
Runtime_Bad_Blocks ......... 1
Přitom badblocks neukazuje žádnou chybu, smartctl long test je "passed".
U ostatních disků se "Runtime_Bad_Blocks " ani nezobrazí.
Tak nevím, co s tím.

Nebude to tím, že by ten disk ten sektor relokoval?
Je Teda fakt, že když jsem měl pár vadných bloků, tak mi disk (asi Seagate) neprošel SMARTem. Ale to se může lišit výrobce od výrobce. Případně tam teoreticky může být nějaký threshold, ale je otázka, jestli bych se do takového thresholdu s ~20 bloky taky nevešel.
