Happened to me before and I guess it's a bug because I didn't have any running process just press ok.
Realy...do you have system without any running processes? I think you should try look into some menagers of processes with write/read disk analyzer and perhaps you can find some processes touched by SD because there are some disk operations that we can't see on our own eyes.
