disk health

Maintaining the health of hard drives is a critical task for anyone managing IT infrastructures, be it in large data centers or personal computers. SMART, or Self-Monitoring, Analysis, and Reporting Technology, is a functionality built into most modern hard disk and solid-state drives that helps in predicting and reporting various indicators of drive reliability. In the Linux world, monitoring this data is straightforward with the use of a powerful tool called smartctl. This utility is part of the smartmontools package, which reads the data from SMART and provides actionable insights to prevent data loss due to drive failure.

When managing servers or maintaining a personal computer, keeping an eye on your disk's health can prevent data loss and ensure system efficiency. This blog post will guide you through utilizing SmartCtl, a tool included in the 'smartmontools' package on Linux, to monitor the health of your disk drives. SmartCtl is a command-line utility that leverages the Self-Monitoring, Analysis, and Reporting Technology System (SMART) built into most modern hard disk drives and solid-state drives. It helps you to inspect the drive's reliability and determine potential drive failures before they happen.
