If a SMART attribute VALUE is below THRESH, what is the recommended action?

If a SMART attribute VALUE is below THRESH, what is the recommended action?

• A. The drive is failing; replace.
• B. Continue using and monitor.
• C. Run a file system check.
• D. Ignore and monitor.

Answer: (A)

SMART tracks the health of a drive by measuring various reliability attributes. Each attribute has a current VALUE and a THRESHOLD. When VALUE falls below THRESH, that attribute is considered failing, signaling a high risk of imminent drive failure. In practice, this means the drive has degraded enough that continuing to use it could lead to data loss. The safest course is to replace the drive and, if possible, back up important data before swapping. Options like continuing to use and monitor, running a file system check, or ignoring the warning don’t address the underlying hardware issue and could result in data loss.
