Disk Inventory & SMART Health
Overview
Full physical disk inventory from the 2026-06-23 diagnostics SMART reports. Age is derived from Power_On_Hours, which reflects cumulative powered-on time, not calendar age since purchase — a drive bought 3 years ago but spun down often will show fewer hours than its shelf age.

Fleet Summary
✅ Zero reallocated sectors, zero pending sectors, zero offline-uncorrectable sectors across every spinning and solid-state disk in the fleet. Every drive reports SMART overall-health PASSED. This is a clean bill of health as of this snapshot.
The 7× Seagate IronWolf array drives are the oldest hardware at ~6.4 years powered-on time — they're the ones to watch first for any future SMART degradation, given they're well past the 5-year mark commonly cited as when AFR (annualized failure rate) starts climbing for NAS-class drives.
Notes / Gotchas
- Power-on hours ≠ calendar age. If these IronWolf drives were purchased used or pulled from another array, actual unit age could exceed 6.4 years.
- Re-run diagnostics quarterly and diff this table — a sudden jump in Reallocated_Sector_Ct or Current_Pending_Sector between snapshots is the earliest warning sign, well before SMART flips to FAILED.
