HDD Alert

Never Lose Data to a Failing Hard Drive Again

HDD Alert continuously monitors the health and temperature of every hard drive in your computer — and alerts you the moment something goes wrong. Whether it's a failing fan, rising temperatures, or a drive reporting critical SMART errors, HDD Alert gives you the early warning you need to back up your data and replace the drive before disaster strikes.

Real-Time Temperature Monitoring

HDD Alert polls each physical disk in your system and reads its current temperature using industry-standard SMART technology. Every drive is displayed in a clean, color-coded dashboard:

Color	Meaning
🟢 Green	Temperature is normal — drive is healthy
🟡 Yellow	Temperature is elevated — warning threshold exceeded
🔴 Red	Temperature is critical — immediate attention required

You set your own warning and critical temperature thresholds, so the alerts match your environment and tolerance.

SMART Status Detection

Temperature is just one piece of the puzzle. HDD Alert also reads the SMART (Self-Monitoring, Analysis, and Reporting Technology) status directly from each drive's firmware. It interprets raw status codes into plain English:

Pred Fail — The drive is predicting its own failure
Degraded — Performance or reliability has degraded
Error — A SMART error has been detected
Non-Recover — A non-recoverable error occurred
And more...

When a drive reports anything other than "OK," you'll know immediately.

Instant Alerts — Wherever You Are

HDD Alert doesn't wait for you to check the dashboard. It actively notifies you through multiple channels:

🖥️ System Tray Icon — Changes color (green → yellow → red) based on the worst drive status, visible at a glance
💬 Balloon Notifications — Pop-up alerts when a drive enters warning or critical status
📧 Email Alerts — Optional email notifications let you monitor drives even when you're away from your computer

Set-and-Forget Convenience

Configure it once and HDD Alert takes care of the rest:

Custom check intervals — Poll every 1 to 60 minutes, whatever suits your needs
Configurable thresholds — Set your own warning and critical temperature limits
Windows startup integration — Automatically launches when you log in
Runs quietly in the system tray — Stays out of your way until there's a problem
