Comment 49 for bug 607560

time settings will not solve this jornaling ext4 issue, that you could get ride of this by removing jornaling from it but it's not a good idea at all.
this is the most annoying bug ever, that I have presenced, the hd noises won't stop until you turn of the pc or maybe change the SO that's seems a great choice.
sorry but.. ext4 sucks a lot no matter what anyone try to prove against, and the sad thing is that there is no secure filesystem that you can rely your /home files if not ext4.
