Unfortunately there are not many ways to turn off head parking
while not turning off power management.
For WD drives there is a special DOS binary for that: wdidle3.exe
which is provided by the support, but not allowed to be redistributed.
You can easily find it on the internet though.
Also I have seen some people doing tricks with sdparm,
but I have not seen a reliable (non-specific to a particular HDD
model) solution yet.
