Maintenance & Troubleshooting

Maintenance Checklist

On installCheck SMART baseline on arrival

Run smartctl -a /dev/sdX and record: Reallocated_Sector_Ct, Power_On_Hours, Spin_Retry_Count. Establishes baseline for future comparison.

MonthlyRun SMART short self-test

smartctl -t short /dev/sdX — takes 1-2 minutes, catches most developing issues. Schedule during off-peak.

QuarterlyRun SMART long self-test

smartctl -t long /dev/sdX — full surface scan, takes 15 hours for 30TB. Any test failure is grounds for immediate replacement.

QuarterlyCheck RAID array health

Verify no degraded drives. A degraded array with no hot spare is one failure from data loss. Check mdstat or controller UI.

AnnuallyVerify drive firmware version

Check Seagate support site for firmware updates. Some versions have known bugs affecting integrity.

Every 3-5 yearsPlan proactive replacement

Enterprise HDDs have higher failure rates after year 4-5. At 30TB per drive, budget for replacements before failures occur.

Troubleshooting Guide

Cause: Loose SATA data or power cable, failed port, or drive not spinning up.

Fix: Reseat both cables. Try a different port. Listen for spin-up sound. Test with a known-good cable.
