Sensor motion on Hitachi 7k500

I am wondering about the sensor motion function if we change original HDD in Macbook pro 13, mid 2009 to Hitachi 7k500. I heard that only the HDD from Apple have that function. All the retail HDD can not have that, is it true?

If that technology not include, is it harmful to the Mac. Anyone have experience should give me a comments. Thanks

No one can help me with those things. Please.....

You heard wrong!
There have been a few HDs such as the western digital scorpio which didn't play nice with Apples sudden motion sensor, but in general, most are fine.
The HD you are looking at is a good HD and will play nice
