which process is writing to disk?

[Lubos Vrbka <lists@vrbka.net>]

hi guys,

i sometimes see the following happenning on my notebook. every few 
seconds, i can hear a tick from the harddrive. it seems, that some 
process writes just a little bit to disk and the heads are immediately 
parked. the sound is quite annoying. it doesn't happen all the time, 
just sometimes.

for example today. memory almost free, swap completely free, small load, 
psi, thunderbird and opera running.

do you have any idea what could be causing this? or is there any way to 
see which processes are accessing the disk in every moment?

thank you in advance for your help. regards,
