Just to let you know: Hitachi uses quite special own technology to park
HDD heads outside of magnetic disks area to a special parking ramp. This
causes HDD heads not to suffer from parking - they're NEVER land on disk
surface during parking. So, actually, Hitachi HDDs can handle a LOTS of
starts\stops without any real problems (a bit like CD\DVD drives do).
Hitachi even recommending aggressive power management on their own to
certain degree due to this fact. However well, stopping HDD every minute
is an overkill anyway. And yes, not each and every HDD has such
wonderful heads parking system.
