Your hard drive or SSD is the heart of your computer, storing all your data, files, and operating system. Over time, drives can slow down, develop errors, or even fail completely — leading to data loss. That’s why monitoring your disk’s health is very important.
Hard Disk Sentinel (HDSentinel) is one of the best tools for checking the health, temperature, and performance of HDDs and SSDs. It helps you detect problems early and prevent data loss on Windows 10 and Windows 11.
In this tutorial, you’ll learn how to use Hard Disk Sentinel step by step.
