Turning off system services causes XP to not recognize removable hard drives

Q: In order to make the computer run faster, I turned off some services of Windows XP, so the computer seems to have a great speed improvement, and the use seems to have no effect. However, I discovered yesterday that Windows XP does not recognize the inserted flash memory or mobile hard disk and must be restarted to recognize it. It must have been shut down what service led to this, but I saw the service, I did not close the "Plug and Play" service? Is there any other service?

A: Previously used Windows Server 2003 I have encountered this problem at the time. The secret lies in the "Removable Storage" service. You must ban it. This service is a bit strange. Other services have descriptions. It doesn't. Maybe you didn't describe it. If you don't know what it is, give it. Forbidden!

In fact, the "Removable Storage" service is a key service for identifying mobile storage devices. Prohibit it will appear the kind of phenomenon you said. Simply put, this service is the service responsible for the management and drive letter allocation of mobile storage devices. So, you only need to set the property of this service to "automatic".
