Hi. I have a friend who has a Macbook pro 2012 non retina with a bad hard drive. We are looking to replace the hard drive, but want to make sure the replacement would be compatible before he makes the purchase. I was looking on Pricewatch and found this drive http://www.superbiiz.com/detail.php...pGg/MlsI1mCFc0tyn1iKw0bmNhSUqR7s4NPa69bo+uICg Which is 2.5" SATA 3. I read that SATA 3 is backwards compatible with SATA 2. Since this is a 2.5" drive I don't see why it wouldn't work with this Macbook. But I just wanted to double check here to make sure there aren't any unexpected kinks that I'm not aware of. I'm much more of a PC person, though I did own a Macbook of my own for about a year. Thanks for your help!
