Before you buy: this is a SAS drive

SAS drives do not plug into a normal SATA motherboard port. You need a SAS host bus adapter or a backplane that speaks SAS - an LSI/Broadcom HBA in IT mode is the usual answer. A SATA drive will run on a SAS controller, but not the other way round. HBA and IT-mode guide

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 2 hours for 4TB. 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 HGST 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 4TB per drive, budget for replacements before failures occur.

Troubleshooting Guide

Cause: HBA not initialized, SAS expander issue, cable fault, or incompatible controller.
Fix: Verify HBA firmware. Check SAS topology with sas2ircu or StorCLI. Test with known-good cable. Confirm drive is SAS not SATA.
