    I am unfamiliar with the math used to calculate that value.

    Would it not work like a parity RAID where each sector would have parity bits in a different location on the disc?

      I’m not familiar with it either, but I’d say that using RAID on a single disc is silly… There’s a good reason it’s not a common practice on single HDDs.

      A scratch on the disc usually means many scratches on the disc.
