The caution indication can be converted to good using CrystalDiscInfo. Click on the caution Button, you will get another window ....
In the resulting window, there are three sliders in the left. Drag them to the ultimate left, and notice the values at the right side are converting to zeros.
Now click the apply button, and notice that the caution is gone.
Now try to run the data lifeguard again. Can you complete it now?
