To determine if the system is affected by this issue, perform the following steps:
1、Open the Start Menu, click on "All Programs", then click on "Accessories". Right-click on "Command Prompt" and then choose "Run as administrator" from the menu that appears.
2、If a prompt appears for "User Account Control", click on "Yes" to allow the Windows Command Processor to run.
3、Type "eccmd.exe -info" (without the quotes) and press Enter. Look at the end of the command output for one of the following scenarios:
（1）、"**ERROR** ECCmd Request device is not available"
(This means that ExpressCache is installed, but the mSATA device is not configured correctly. Uninstall ExpressCache from "Programs and Features" control panel, and then refer to the Solution section of this document.)
（2）、"'eccmd.exe' is not recognized as an internal or external command, operable program or batch file."
(This means that ExpressCache is not installed. Refer to the Solution section of this document.)
（3）、"Cache Read Percent : x.xx%" (where x.xx% is some actual percentage)
"Cache Write Percent : x.xx%" (where x.xx& is some actual percentage)
(This means that ExpressCache is installed and working properly. No further action is needed.)
命令运行后会给出结果：
（1）、设备不支持ExpressCache："**ERROR** ECCmd Request device is not available."
（2）、没安装好ExpressCache程序："'eccmd.exe' is not recognized as an internal or external command, operable program or batch file."
（3）、ExpressCache运行良好："Cache Read Percent : x.xx%" ，此时，如果启动速度快了，也可以验证运行状态是正常的。有可能刚安装启用ExpressCache系统还没那么快就缓存那个多数据到SSD的14GB分区里，所以前几次重启可能还是比较慢。
如上，如果觉得慢，用eccmd.exe -info命令可以确认你笔记本的ExpressCache服务有没有运行。
命令成功运行后结果如图，Used Data Size这些数值会随着电脑使用的频繁而逐渐增加，这些数值越大说明这个功能越处于最优状态吧：
