返回结果中的id#为194的属性(Temperature_Celsius)表示输出硬盘温度，所以才会有软件能够监测到硬盘的温度。我们从这里也可以直接看到硬盘当前的温度为39°C，理想的状态是控制在5°C左右，所以应该增加风扇了。
-a 显示设备所有的SMART信息。
-l error 列出硬盘错误日志。如果显示没有错误最好，如果显示了大量的错误信息，那就该着手准备替换硬盘了。
-l selftest 列出自行测试结果。
利用smartd进行自动监控
smartd是smartmontools软件包中的一个实用程序，可以单独运行，也可以注册为系统服务，Windows上的注册命令为：
>smartd install
注册后，打开services.msc，可看到一个名叫“SmartD Service”服务，并设置为“自动”启动。
在非Windows平台上可通过向/etc/rc.d/init.d添加smartd脚本，其实在安装smartmontools软件包的时候通常会安装到这个位置，只需要在对应的启动级别下做一个软链接就可以了。
smartd的配置文件为smartd.conf(Windows和非Windows平台都叫这个名字，Windows平台与smartd.exe在同一个目录下，非Windows平台位于/etc目录下)，在这个配置文件中已经内置许多种监视方法和参数说明，值得一体的是-m参数，可以利用它将监视报告以邮件的形式发送给指定的E-mail地址，这样设备管理员就可以坐在电脑前就可以掌控所有硬盘设备的健康状况了。
