I run continously run Serious Samurize to show graphs of CPU, disk and network usage. Occasionally I see that my E: drive (a hard disk with no system files on it, only data) is thrashing away when it shouldn't be (showing around 50% bandwidth usage on the graph). Using process explorer I see that the culprit is CcmExec, a standard Windows component. It looks like it is reading every file on the disk.
So, my question, why is CcmExec doing this to me? And, how do I stop it? Suspending CcmExec from process explorer works well, but I have to remember to do this every time I start my machine. I suspect there's a better way to tell it to keep its dirty fingers of my E drive.
I'm running Windows XP on a company network.
