In the example below, it shows that the boot disk has the issue (not clean) while the Data disk is fine (clean).
In this case, when scanning/repairing the disk, the boot device is required while the data drive is not; this would save significant time. Boot disk scan may take only seconds, while a 4TB RAID disk could take 30+ minutes.
