    Description

      When the Volume scanner sees a corrupt block, it restarts the scan and scans the blocks at much faster rate with a negligible scan period. This is so that it doesn't take 3 weeks to report blocks since a corrupt block means increased likelihood that there are more corrupt blocks.
