This is more difficult that it sounds. Section 4 of the Battery-Powered
mini HOWTO (which is a bit out of date) has some useful advice. You are
doing it right...but something is touching the filesystem (or swap) on
the drive. It would be nice if there would be some way of enabling
logging to say what process touched the filesystem. Of course the
logging itself would touch the filesystem (on a laptop :)).
