MonSMART

Read-only SMART monitor that compares disk health over time and warns when something changes.

Periodic monitor, not a live dashboard or a repair tool.

Quick start

1. Download a prebuilt binary from Releases, or build bin/MonSMART.exe with build.ps1.
2. Install smartctl from smartmontools and make sure it is on PATH.
3. Review bin/.cmds, bin/.smart, and bin/.conf.
4. Run bin/MonSMART.exe as administrator. It prints a verdict and shows a popup.
5. Schedule the exe daily or weekly with Task Scheduler.

What it does

• Runs the configured smartctl checks.
• Saves each run under logs/runs/<timestamp>/.
• Compares the new result with the newest readable baseline.
• Exits 0 when nothing important changed.
• Exits 1 and shows a warning popup when health, endurance, an important attribute, or the device list changed.
• With warnOnly=true, healthy runs show no popup. By default, a summary popup appears after every run.

Requirements

• Windows 7 or later with .NET Framework 4.0 or later.
• smartctl from smartmontools.
• Administrator rights for full SMART data.
• Keep bin and logs as sibling folders.

Limitations

• Windows-only: built on WinForms and Windows APIs.
• smartctl is not bundled; configure it in bin/.cmds.
• No drive discovery; add every device to bin/.cmds and its attributes to bin/.smart.
• No daemon mode; use Task Scheduler.
• Locale-sensitive parsing; the parser expects English smartctl output.
• Read-only is enforced, not guaranteed; a user can still edit .cmds to add repair commands.
