Mac端自动监控硬盘的S.M.A.R.T.信息-马春杰杰

在Mac下想要监控硬盘的S.M.A.R.T.信息还是有很多办法的，很多软件可以办到，比如：

SMART Utility、SoftRAID，Disk Drill不过这些软件都是收费的，另外也比较占资源。这些我都用过，不过感觉Disk Drill并不太准，这个工具主要是恢复数据用的。

我有个盘出现了坏道，上面三个工具中，前两个都能识别，最后一个却显示正常~~

后来决定还是用开源的工具smartmontools：

smartmontools-7.1-1

最新版安装之后，路径为：/usr/local/sbin，所以装完之后需要将该目录加到环境变量中，添加方法如下：

MacOS：command not found

装了个smartctl工具，但是用的时候提示： mcj@mcjdeiMac:/usr/bin$ smartctl -bash: smartctl: command not found 这么一看是没有添...

添加之后就可以使用了，使用方法为：

smartctl -a /dev/disk0

这样就可以查看disk0的S.M.A.R.T.信息：

mcj@mcjdeiMac:~$ smartctl -a /dev/disk0

如果你看到的不是这么详细的信息，而是短短的：

SMART is disabled

那就应该手动打开：

/usr/local/sbin/smartctl -s on -S on -o on /dev/disk0

之后就是后台监控S.M.A.R.T.信息了：

/dev/disk0 -a -d sat -S on -s (S/../.././02|L/../../6/03)

这里的-d sat是指定你设备的连接类型为SATA，后面指定每天凌晨2点运行一个简短测试，每周六的凌晨3点跑一个长测试，输出的日志会体现在/var/log/system.log里，你可以打开控制台看，也可以自己根据需要用-l参数配置输出到其他地方。这里举例只写了一个设备，有多个设备需要监控的，再加一行就行了。

最后需要注意的是OS X上用LaunchDaemon来启动服务，因此到/Library/LaunchDaemons/下增加一个plist文件吧，plist下载地址见文末。
