In the context of disk health metrics, what does the VALUE column represent?

• A. Normalized health score (100 usually healthy threshold)
• B. Failure threshold
• C. PRE-FAIL = critical; OLD-AGE = expected wear
• D. Count of bad sectors remapped to spare area

Answer: (A)

The VALUE column shows the normalized health score for each SMART attribute. It’s a scale where 100 typically means the attribute is in good condition, and lower numbers indicate deterioration. This is a relative health indicator, not a raw measurement or a direct failure flag. The actual threshold that signals potential failure is in the THRESH column, and the RAW value provides the raw measurement (like counts of reallocations). The WORST value tracks the lowest normalized score seen for that attribute. When VALUE approaches or falls below the threshold, the attribute may be failing and warrants closer monitoring.
