In my case, I want to emphasize the following: my WD Green drives are
strictly a data store.  The system runs from a compact flash card.
Though I disabled them anyway, many daemons, such as syslog, sshd,
cron, fetchmail, etc, should only affect the *system* drive.

However, daemons like nfs and smbd can obviously affect the data
store.  Even so, I wouldn't expect them to cause a disk access unless
a request is made.

The point is, in my opinion, a non-system partition should be that
much easier to make "truly" idle... still, I can't figure out how to
do it.
