Linux下centos使用smartctl 检测独立物理服务器SSD硬盘型号和Smart信息 机械磁盘坏道，09通电时间

安装

1. yum -y install smartmontools
   

复制代码

检查磁盘的 Smart 功能是否启用，/dev/sda为你的磁盘，一般都是这个，可以通过df -h查看输出的磁盘是什么。

1. smartctl -i /dev/sda
   

复制代码

返回如下信息

上面输出中的最后两行显示了SMART功能已启用
根据你的需求进行选择是否启用或者禁用SMART功能。
启用磁盘的 Smart 功能

1. smartctl -s on /dev/sda
   

复制代码

禁用磁盘的 Smart 功能

1. smartctl -s off /dev/sda
   

复制代码

显示通电时间

1. smartctl -a /dev/sda | grep Power_On_Hours
   

复制代码

显示磁盘信息，一个IDE，一个SATA，看哪个能用就哪个，输出内容是一样的

1. smartctl -a /dev/sda
   

复制代码

1. smartctl -a -d ata /dev/sda
