What does the TYPE column represent?

• A. PRE-FAIL = critical; OLD-AGE = expected wear
• B. Normalized health score category
• C. Failure threshold
• D. Reallocated sector count

Answer: (A)

In SMART attribute reporting, the TYPE column shows how each attribute relates to drive health by indicating whether it’s a predictive, pre-fail indicator or a wear-out (old_age) indicator. PRE-FAIL attributes signal that a failure could be imminent and are considered critical predictors, while OLD-AGE attributes reflect normal wear accumulated with use and don’t directly predict sudden failure. So the TYPE column is signaling that the attribute types here are PRE-FAIL (critical/predictive) and OLD-AGE (expected wear). This isn’t about a normalized health score, a specific failure threshold, or a single attribute like reallocated sector count. When monitoring, you’d treat PRE-FAIL attributes as urgent indicators to investigate or replace, and OLD-AGE attributes as wear trends to watch over time.
