I have just purchased (well on the day of release) the base model MBP (late 2008). I was actually going for the 2.4 Alu MacBook but due to long and unintersting complications and a twist of luck I was offered the MBP for £10 less than I could have got the 2.4ghz MB for. It is the standard configuration and Im looking to upgrade the HDD. Im looking to add a 320gb (+) HDD that runs at 7200rpm, what specifications do the drive need to fulfill to be compatible. So far I understand it needs to be a 2.5" laptop drive with SATA connectivity. Are there any other requirements or are those quoted incorrect. Is there a maximum drive size that is compatible (gb not physical size). I live in the UK so if you know a good retailer that would be great too. Dabs seem to be pretty good. Sorry this thread seems to go on, last Q though; brand? Which brand has people found reliable, I have heard mixed things about WD but have had no problems with my external WD HDD I have had for over 2 years now. I've also heard good things about seagate. All help is much appreciated.
