• One physical drive marked as “Failed” or “Missing”
  • Array still accessible, marked as “Degraded”
  • System logs show predictive failure warnings or SMART alerts
  • RAID 6 is still operational — it can handle one failure
  • But you are one step away from disaster
  • Silent read errors may already be present

RAID 6 gives you a buffer — but not immunity. Take action while you still can.
