From my understanding, this sound is caused by the internal
cache. I have a ProDrive 105S as well, and the literature says
that its cache has a look-ahead feature. When the drive's idle,
my guess is that it reads the "next" piece of data from the drive
and stores it in the cache.
Or so the tech support says who sold me my 105S.
