// CHKDSK_VERBOSE
//  - For FAT, chkdsk will print every filename being processed
//  - For NTFS, chkdsk will print clean up messages

//  - Perform sector checking on free and allocated space
// CHKDSK_EXTEND
//  - For NTFS, chkdsk will extend a volume
// CHKDSK_DOWNGRADE (for NT 5 or later but obsolete anyway)
//  - For NTFS, this downgrade a volume from most recent NTFS version
// CHKDSK_ENABLE_UPGRADE (for NT 5 or later but obsolete anyway)
//  - For NTFS, this upgrades a volume to most recent NTFS version
// CHKDSK_RESIZE_LOGFILE
//  - For NTFS, this changes the size of the logfile
// CHKDSK_CHECK_IF_DIRTY
//  - Perform consistency check only if the volume is dirty
// CHKDSK_FORCE
//  - Forces the volume to dismount first if necessary (implies /F)
// CHKDSK_SKIP_INDEX_SCAN
//  - Skip the scanning of each index entry
// CHKDSK_SKIP_CYCLE_SCAN
//  - Skip the checking of cycles within the directory tree
// CHKDSK_ALGORITHM_SPECIFIED
//  - For NTFS, this indicates an algorithm value is specified.
//    This bit cannot be used together with CHKDSK_SKIP_INDEX_SCAN
