This is a Samsung HD103UJ by the way. That can be ok. It probably tried writing and then rereading and when that worked it decided the sector didn't really have a 'hard' error (like a physical defect on the platter) and thus didn't need to be reallocated to a spare sector. You could generate an unreadable sector during a write by the power failing or with excessive vibration. That said, the drive firmware could also be broken -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
