Reading SMART Health Correctly
/smart-status assigns a verdict per disk based on the SMART values:
| Verdict | Trigger |
|---|---|
critical | health FAILED, reallocated sectors > 100, pending > 0, or temperature > 55 °C |
warn | health unknown, 1–100 reallocated sectors, or temperature > 45 °C |
pass | everything in the clear |
Reallocated and pending sectors are the most important early warning signs of a dying disk — a single pending sector already triggers critical. If smartctl shows nothing useful, set smartctl_device_type: sat in the profile. Passwordless sudo for /usr/bin/smartctl is required.
