Download S.M.A.R.T. Monitoring Tools – Check and Monitor HDD/SSD Health

S.M.A.R.T. Monitoring Tools (smartmontools) is a free, open-source suite of utilities for monitoring and analyzing the health of hard disk drives (HDDs) and solid-state drives (SSDs) using the Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) system built into modern storage devices. It helps you detect early signs of drive failure before data loss occurs.

The suite consists of two main tools: smartctl, a command-line utility for one-time S.M.A.R.T. queries and disk tests, and smartd, a daemon that runs continuously in the background and sends email alerts when warning conditions are detected on monitored drives. Together they provide both on-demand diagnostics and continuous monitoring for your storage devices.

smartmontools reads and interprets S.M.A.R.T. attributes like reallocated sectors, pending sectors, uncorrectable errors, power-on hours, and temperature — giving you an early warning of potential drive failure. It is used by system administrators, IT professionals, and home users worldwide to proactively manage storage health and prevent data loss.

Key Features

• S.M.A.R.T. attribute reading – Display all SMART attributes for a drive including reallocated sectors, pending errors, temperature, and power-on hours.
• Self-test execution – Run short, long, conveyance, and selective self-tests on drives to identify physical problems and bad sectors.
• Background monitoring daemon – The smartd daemon monitors drives continuously and sends email or script-based alerts when failure indicators are detected.
• ATA and SCSI support – Monitor both ATA/SATA and SCSI/SAS drives, as well as NVMe SSDs on supported systems.
• RAID and USB support – Access drives behind some RAID controllers and USB enclosures using device-specific options.
• Detailed error logging – Read the drive error log and self-test log history stored on the drive itself for past failure events.
• Cross-platform – Runs on Windows, Linux, macOS, FreeBSD, and other POSIX systems with consistent functionality.

How to Install

1. On Linux, install via package manager: sudo apt install smartmontools (Ubuntu/Debian) or sudo dnf install smartmontools (Fedora).
2. On Windows, download the latest smartmontools installer from the official website (smartmontools.org) or the link provided above and run the setup wizard.
3. On macOS, install with Homebrew: brew install smartmontools
4. After installation, run smartctl -a /dev/sda (Linux/macOS) or smartctl -a /dev/pd0 (Windows) to display all SMART attributes for your first drive.
5. Run a short self-test with smartctl -t short /dev/sda and check results after a few minutes using smartctl -l selftest /dev/sda.
