I own a 500GB Seagate FreeAgent Go HDD. I had bought it in 2008. I own a Macbook Pro 13(2009 model) with only 160GB of hard drive space. With the escalated prices of the hard drives right now I am not ready to invest in a new HDD> I was planning to remove the hard drive from the Seagate and install it in my Macbook. I wanted to know will it fit in my Mac? I am including a photo of the HDD I own, as a reference.
