I assume I can do so without a warranty issue. I have a current generation MBP 2.4 (bought off the refurb site) and I am looking to get a faster 7200rpm drive in there. Battery life is not an issue to me, where I travel I doubt I won't have access to external power. Is there a consolidated thread about people's choices for new HDD and their experiences? (searching nets me pages which I may just read through). I do not plan on a SSD at this time.
