简介

smartmontools 包含两个程序 smartctl 和 smartd，用于控制和监控存储系统：

• 检查硬盘（HDD/SSD）的健康状态
• 预测硬盘故障风险
• 执行硬盘自检（如短/长测试）
• 查看温度、通电时间、坏扇区等关键指标

SMART 指的是 Self-Monitoring, Analysis and Reporting Technology System

pySMART 是 smartctl 的 Python 封装，兼容 Linux 和 Windows

建议使用管理员权限运行

安装

pip install pySMART

Windows

下载 smartmontools 或从 releases 下载

Linux

apt-get install smartmontools

yum install smartmontools
