Suse accessing hard drive constantly

I have SUSE11.3 installed on an Acer Aspire 5517 laptop with 4gb of ram and 250gb HD.

This is a dual boot machine with Windows 7 and when running that OS, hardrive accessing is infrequent and my battery life is great.

With SUSE running, the hard drive is accessed every 10 seconds (or so), even when I’m not doing anything on the machine.

I’ve done some web searches on this and haven’t found the answer. I was hoping someone could help me diagnose what process is reading the HD so often and how I might change that?

Any help is very much appreciated!

I would monitor both running processes and harddrive accessing first. For running processes:

top

Harddrive:

iotop

You will have to install ‘iotop’ before being able to use it. Observe both for some time, that might give you a hint what’s going on.

Is this causing a performance drop? Or is it merely the flashing light that’s bothering you. A blink every 10 secs could be just some logging.

maybe it is your ext4 doing background work keeping everything
tidy…[don’t really do this, but think on] try letting the battery
run completely out while in windows, and again in openSUSE and see
which one lives to boot again, with no problems…and, then you might
like what ext4 is doing for you and your data…

in addition to the other hints given, you may find some interesting

Install “laptop-mode-tools”, and activate them. Perhaps install the
“patterns-openSUSE-laptop” meta package.

Also, deactivate search thingies of the style of beagle or ¿nepomuk?
