Hello! Yesterday, after much debate, I've upgraded my late 09 macbook with a 7k500 500gb and 4gb (2x2) of crucial RAM. Everything went smoothly following the Ifixit guides. Used superduper to copy everything to the hd in an external enclosure, swapped them out, selected it as startup drive and GO! However, since the swap the macbook takes a lot longer to start up...From the moment I press the button it'll take quite long (10 sec) before the apple logo appears, then another 20+ sec. (with the rotating disc on screen) before everything is ready to go at the desktop. My girlfriend has got an macbook (identical to how mine was before) and it boots much quicker! Any advice at where to look to get everything going at blistering speeds again ? Cheers!
