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. -- Roman Kyrylych (Роман Кирилич)
