See /usr/local/etc/rc.d/ataidle.sh for sample rc.conf settings to run ataidle on disk/s at boot. I'm now using 'ataidle -P 0 0 0' which disables APM altogether on ad0, after finding I'd used up 25% of my nominal lifetime allowance of ~2M Load_Cycle_Counts in just under a year powered up over about 18 months, so I was very glad to find out about this. (Fujitsu MHV2040AH) You'll need to run ataidle again in /etc/rc.resume if you're suspending your laptop. You could even run different settings on battery or AC ..
