Hi. I recently upgraded my MacBook Pro from 4GB of memory to 8GB of memory. At the same time I upgraded the 250GB internal hard disk with a 500GB Seagate Momentus XT hard drive. The MacBook Pro works fine once it has started up. But it takes significantly longer to boot up than it used to. With more memory and an internal hard drive with solid state memory, I expected the machine to boot up faster. Is there something else that I should be doing, such as re-setting PRAM? Or maybe I just need to re-install the old memory and hard drive, one at a time, to see which component is causing the longer boot time. Thanks.

MacBook Pro, Mac OS X (10.6.2)

    This may not explain everything, but your Mac tests its RAM when it starts. It takes longer to test more RAM. If you want to investigate the issue, I'd start by reinstalling the old RAM.

    You might also use the Console utility to see if there are any messages that could explain the slow boot.

    Hi,

    I think your Macbook is searching the startup disk (the old one). Just go into the System Pref --> Startup, choose your hard drive and reboot. Should be faster.

    Regards,
