Constant disk activity

[prelude_2_murder at yahoo.co.uk (first last)]

Hi,

I am running centos on a laptop and the HD keeps on making noises every
so often, even when I go to runlevel 1 and stop everything that could
be doing so (hotplug, smartd, cron, anacron, atd, syslogd...).

Is there any way of finding out what is accessing the disk? Not only it
shortens battery life, it is annoying while working in a quiet room.

Thanks

Gabriel
