Likely the noise you are hearing roughly corresponds to Load_Cycle_Count.
Yours is quite high. You may be able to use sysutils/ataidle to disable
the parking like so:
ataidle -P 0 /dev/ada0
Not entirely sure if this works on the ada driver, so if not you might want
to ask on freebsd-stable@ or boot up in a Live CD of Linux and use the
tools there.
