## Overview

- **Who it's for**: Windows users and PC technicians who want an early warning on failing hard drives or SSDs, from casual users checking a laptop drive to IT staff monitoring multiple machines.
- **What you get**: CrystalDiskInfo reads S.M.A.R.T. data to show drive health status, temperature, and power-on hours at a glance, with support for HDDs, SSDs, USB, Intel RAID, and NVMe drives. It tracks detailed SMART attributes over time, can run resident in the background with email alerts on health changes, and offers AAM/APM control for HDD noise and power settings. It's free, open-source, and ships in several themed editions (Standard, Aoi, Shizuku, Kurei Kei).
- **How it works**: Download and install the app on Windows (XP through 11), then launch it to automatically detect connected drives and display their SMART data and health status. Optionally enable the resident monitor to run checks in the background and send email alerts if a drive's health deteriorates.
