Disk writes for logger

Hi, I know someone told me ages ago about this but I've forgotten:- I have a clean install of SuSE7.3 on a "new" server. Even before configuring it, every four seconds or so it does a write to disk. My guess is that it is some form of logging but I've tried disabling various processes without stopping it. Any ideas - it isn't a problem so much as an annoyance! -- Best wishes, Derek
