Monitoring Disk Health with S.M.A.R.T.
S.M.A.R.T. is the self-monitoring function of HDDs, SSDs, and NVMe drives that reports imminent disk failures early. This overview explains the key values and links to the guides for Linux and Windows servers.
Why Monitoring Matters
Monitoring these values is a crucial part of proactive server maintenance. S.M.A.R.T. gives you an early warning to back up your data and request a drive replacement before a critical hardware failure occurs.
Key Indicators
- Overall Health Status: A simple "Passed" or "Failed" assessment from the drive.
- Reallocated Sectors Count: Number of bad sectors replaced by spare ones. A rising value indicates the drive is nearing the end of its life.
- Percentage Used (NVMe): Estimate of the drive's rated lifespan consumed.
- Power-On Hours: The total time the drive has been powered on.
"Proactive action saves downtime. As soon as S.M.A.R.T. shows critical values, the drive should be replaced as part of our free hardware service."
Guides by Operating System
S.M.A.R.T. reports "Failed"?
Don't wait: If a drive in your dedicated server reports a negative diagnosis, we will replace it free of charge. Simply open a hardware ticket in the PowerPanel. On VPS, our sysops monitor the host drives and replace them themselves.
