By default bad_limit is set higher than md5_mismatch, so that mismatches are
classified as quality class "0" rather than "\-". This means that the sectors
of a MD5 mismatch range are recorded in the sector_map as successfully read,
if the drive handed them out at all. Set "bad_limit=md5_mismatch" to let the
sector_map record the whole mismatching range as yet not retrieved.
