I notice disc activity every two seconds on my SuSE 10.1 text based

I want to put the disc in standby after 15 minutes with the "$hdparm -

disc never gets into standby.
Any ideas?

I notice the same thing with my laptop (openSUSE 10.2). I uninstalled
beagle and it still happens.It is hald that is checking hardware. Try
as root:
rchal stop
wait some time for pdflush to save on disk what it has to save (some 35
seconds), do nothing with computer and see is there any activity.

Don't forget to turn hald again on with:
rchal start
you need it for the new connected hardware like USB devices.

Thanks for the answer. The machine I have this problem on is a server
to which I never connect new hardware.
Does that mean I can leave hald off? Or will hald stop accessing the
disc until there is new hardware connected if I turn it on again?

Hi Ake,

Good question.
HAL is Hardware Abstraction Layer that I don't know very well.
I guess it is possible to turn HAL demon off if there is no need to monitor
hardware, but be careful.

I recall that SuSEwatcher that was used before hald for the same purpose, to
monitor new plugged hardware, I kept off without any problems. Off course
any hardware that was connected, CD inserted, etc. I had to mount and
unmount manually.

There is another program that I mentioned, pdflush, that is used to flush
hard disk cache. It can produce regular HD activity if there is something
that has to be written to HD. Changing its parameters to increase period of
inactivity, will increase your chances to loose cached data that are not
synced with hard disk.
