For what its worth,
On a laptop I was finding that the disk would spin up approx every 15
seconds. Some pokeing around found the culprit....
Turned out that squid (yes on a laptop :-) probes one of its cache
directories every 15 seconds. Now with 16 first level and 256 second
level directories being used to construct the cache, some quick math
16 * 256 * 8k(block size)
And squid was very slowly working its way through this, each time a new
directory was read it missed in the buffer cache :-(. Tweeking squid's
config to reduce the number of directories fixed the problem.
Perhaps something to add to the APM notes.
