I do not think there is a state in modern HDDs that there would be a sector which consistently takes 30-120 seconds to read. Those are either unreadable at all, or readable after a delay -- and then already remapped by the HDD into the reserved zone, so the delay is not there the next time.
I have seen drives with abysimal read speed with constant hiccups when reading. When reading your text below I believe you're implying that a drive will re-write or re-map a sector that took 5 seconds to read. I wish this was true, but from what I've seen that is just not happening. If you have evidence that contradicts this, do share.
