Your disk is doing thermal recalibration. Some disks seem to do it
more than others. Tweaking some powersave things can help (the thermal
state becomes more consistant) but often there is no way to get rid of
it and it seems to be more common in newer disks.

Unless it gets really loud I just ignore it.
