I am looking at these two HDs to replace in my version 5,5 MBP. http://www.newegg.com/Product/Produ...0711-Index-_-LaptopHardDrives-_-22136280-L01C http://www.newegg.com/Product/Produ...22810-Index-_-LaptopHardDrives-_-22136692-L0D The later one had a review that said the buyer could not get it to work on his MBP of the same version. I just wanted to clarify and see if this was true. If it is, then what HD should I be looking at for around $60? I got a lot of help with picking this Mac here, so I figure I could get good help with this dumb question. Thanks.
