[Gllug] what is causing disk activity ?

[Alain Williams]

The disk on my main-server/desktop seems to be continually chattering.
What is causing it. I'm not really doing anything other than type stuff in
emacs. So what is causing it ? Being paranoid I am wondering if I have been
rooted.

Is there any way that I can relate the disc activity to processes ?

It is a Centos 5 based system.
