Hi, I need to upgrade my 160GB hard drive. Are any of these Internal hard drives compatible with my 13-inch Macbook Pro from Mid-2009. If so, which one would you prefer to purchase? http://www.amazon.com/Samsung-SpinP...ref=sr_1_9?s=pc&ie=UTF8&qid=1318460395&sr=1-9 http://www.amazon.com/Western-Digit...ref=sr_1_1?s=pc&ie=UTF8&qid=1318459902&sr=1-1 http://www.amazon.com/Western-Digit...ref=sr_1_3?s=pc&ie=UTF8&qid=1318459984&sr=1-3 http://www.amazon.com/Western-Digital-Scorpio-2-5-Inch-Notebook/dp/B005DVJJWQ/ref=dp_ob_title_ce Thanks!!
