What constitutes a SMART attribute threshold breach?

What constitutes a SMART attribute threshold breach?

• A. VALUE drops below THRESH — drive is failing.
• B. VALUE rises above THRESH — drive is healthy.
• C. THRESH is ignored.
• D. The attribute count increases.

Answer: (A)

In SMART monitoring, each attribute has a threshold value that defines the minimum acceptable level. A threshold breach occurs when the normalized VALUE falls below that THRESH, signaling the attribute has degraded enough to indicate the drive may be failing. That’s why the statement VALUE drops below THRESH — drive is failing is the correct interpretation. If VALUE rises above THRESH, that’s generally within a healthy range and not a breach. Ignoring THRESH or counting attributes doesn’t describe a breach either. So the key idea is that dipping below the threshold triggers the warning of potential drive failure.
