Hi, I just ordered an OWC 120GB Mercury Pro SSD and want to move the original 5400 rpm 500gb drive on my Macbook Pro 13" (2010, 7,1 model) to the Optibay drive using the included Data Doubler Kit. (Thanks to everyone who helped me choose). I want to use the 5400rpm drive only for storage at the end of the day(move all data) and the SSD for processing video and still images. If I do not access the drive will it stay off and park the heads. I work in areas with a lot of bumps and vibrations and want to know that I am not damaging the HDD 5400rpm with SSD only running. I heard the putting the HDD in the Optibay slot will disable sudden motion sensor and temperature sensors and I'm afraid that bumps might not trigger the SMS. Thanks.
