Smartctl is a command-line tool that 'controls the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into most ATA/SATA and SCSI/SAS hard drives and solid-state drives.' That done, you can manually #Run a test and #View test results, or you can use #smartd to automatically run tests and email notifications. You can use #smartctl to check for and enable SMART support. SMART support must be available and enabled on each storage device to effectively use these tools. Install the smartmontools package to use these tools.

The smartmontools package contains two utility programs for analyzing and monitoring storage devices: smartctl and smartd. Statistics are collected (temperature, number of reallocated sectors, seek errors.) which software can use to measure the health of a device, predict possible device failure, and provide notifications on unsafe values.

(Self-Monitoring, Analysis, and Reporting Technology) is a supplementary component built into many modern storage devices through which devices monitor, store, and analyze the health of their operation.
