hello,
i recently built a home network server on freebsd 5.3 and am now looking for a way to keep it's hdd in power saving mode - the server is basically a pentium 166mhz machine, and the sound the hard drive is really annoying, as the machine is next to my bed. moving it is not an option - the cat5 cable alone would cost more than the machine itself did.
i have already got rid of most of the logging in /etc/syslog.conf.
i also commented out the */5 * * * * root /usr/libexec/atrun, */11 * * * * operator /usr/libexec/save-entropy and 0 * * * * root newsyslog lines in /etc/crontab as they do not serve much purpose to me, so the only one remainig constantly hdd accessing process that i can think of is cron itself.
so i am looking for a way to disable cron's automatic /etc/crontab and /var/cron/tabs checking. is there a way other than recompiling the source code with the checking commented out? if not, where exactly can i get the source and where in it lies the checking - i have no idea of how good documentation/commentation the source might have. also, if you can think of any other processes that might be accessing the disk often, could you let me know?
here is a copy of my "ps ax" to help with that:

if there might be anything unwanted running but not showing up in the list, also your help would be helpful.
thank you!
