Python读取硬盘所有信息的完整方法
作者：XerCis
这篇文章主要为大家详细介绍了Python读取硬盘所有信息的相关方法,文中的示例代码讲解详细,具有一定的借鉴价值,感兴趣的小伙伴可以跟随小编一起了解下
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
列出系统中的硬盘
lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 256G 0 disk sdb 8:16 0 256G 0 disk /
或
smartctl --scan /dev/sda -d ata # /dev/sda, ATA device /dev/sdb -d ata # /dev/sdb, ATA device /dev/sdc -d nvme # /dev/sdc, NVMe device /dev/sdd -d scsi # /dev/sdd, SCSI device
实现代码
from pySMART import DeviceList device_list = DeviceList() devices = device_list.devices print(devices) # [<ATA device on /dev/sda mod:ST4000VX000-1F4168 sn:Z302B410>, # <ATA device on /dev/sdb mod:ST8000NM0055-1RM112 sn:ZA1F6NQX>, # <NVME device on /dev/sdc mod:Samsung SSD 970 EVO 500GB sn:S466NX0M733342K>]
