Resolved against manufacturer compatibility lists we read and dated, capped at 4. Vendor-listed means the manufacturer names this exact part number; fit-verified is our own check of form factor, interface and recording technology against a published requirement. Neither is a guess, and a drive the registry cannot resolve shows nothing here rather than a maybe. How compatibility actually works

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 8 hours for 16TB. 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 16TB 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.
