Hi rjlee,
Ok i am having this problem as stated also with those kinda disk access noise pollution problem. Was searching for it quite a bit and found out this thread might help but the noatime should i include it only on my /dev/hda* mountpt or all the entries in fstab like /proc /sys etc? cos i added onto the /dev/hda3 which in this case is LABEL=/ doesn't seems to eliminate the problem.
Thanks
fstab
