Instant Drive Health Overview
CrystalDiskInfo shows a color-coded health status, so you can see at a glance whether your drive is in Good, Caution, or Bad condition without decoding raw numbers.
Beginner's Guide
If you've ever wondered how to check whether your hard drive is starting to fail, CrystalDiskInfo gives you a fast, readable answer.
START WITH THE BASICS
CrystalDiskInfo is a lightweight, open-source utility created by Crystal Dew World that monitors the health of your storage devices. It reads Self-Monitoring, Analysis, and Reporting Technology (SMART) data that most modern hard drives and solid-state drives expose about their own internal condition over time.
By translating this technical data into easy-to-understand statuses and attribute readings, the software helps you spot potential trouble early. Signs such as rising temperatures, increasing reallocated sector counts, or longer spin-up times appear before they cause noticeable slowdowns or data loss.

It works with internal HDDs, SSDs, USB drives, and several RAID configurations, so most users can monitor common storage devices from one simple interface.
