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. -Matt
