My laptop's hard drive indicator is slightly flashing, even when idle.

How do I figure out which process is causing the hard drive activity and stop it? I believe there shouldn't be any hard drive activity that goes on all the time.

My laptop is Lenovo ThinkPad X200 with 8GB of RAM, most of which is unused. Hard drive is Intel 520 120GB. Ubuntu 13.04 64 bit.

Update: so, using iotop, I have caught chrome, firefox and jbd2/sda3-8 at disk writes. What can I do now and what is this jbd2/sda3-8 thing?

iotop results 1 iotop results 2

    your hard disk is always going to be getting hit a little bit - stuff writing to log files, temp data being flushed to disk etc. – TheFiddlerWins Sep 11 '13 at 20:45
  • I don't believe there's valid reason to write log files every second or two. There should be no reason to swap either, when the system is idle and less than half of RAM is utilized. – Nickolai Leschov Sep 19 '13 at 00:58

iotop is useful for listing the processes disk usage
