  • It does not affect the corresponding cluster number on a FAT table; only the corrupted portion of the sector is prevented from being written to.
  • It does affect the FAT table. The corresponding cluster number is marked as bad; however, only the corrupted sector within the cluster is prevented from being written to.
  • It does affect the FAT table. The corresponding cluster number is marked as bad and the entire cluster is prevented from being written to.
