VMS Help  —  ANALYZE  /DISK_STRUCTURE, /READ_CHECK
    Determines whether the Analyze/Disk_Structure utility performs
    a read check of all allocated blocks on the specified disk.
    When the Analyze/Disk_Structure utility performs a read check,
    it reads the disk twice; this ensures that it reads the disk
    correctly. The default is /NOREAD_CHECK.
