MBP Booting Really Slow

I have a 13.3 MBP Mid 09' 2.26GHZ, I have upgraded to 4GB RAM and have also put in a 500GB HDD (Western Digital Scorpio Blue), I find that when booting from off that the MBP can take upto 3-4 minutes to start up. I am the only user on the MBP and only have about 3 applications on start up (log me in, dropbox and VMware helper).

When I installed the other HDD I used superduper to clone the disc. I did not build any partitions or change the HDD at all (although I did format is to OSX Standards).

Can anyone help me on why it is taking so long to boot up? Did I need to build a GUID parition (only thing I can find that I havnt done)?

Cheers All

p.s. it make is really annoying when I also use a 21" iMac that boots like a dream

Mac OS requires that you build a GUID partition for the installation to work fine. You may not have experienced this error as you cloned your old disc.

"You cannot install Mac OS X on this volume..." alert in Installer

Also, a disk running on a non-GUID table means you can't install FW updates on it. It renders the disk unusable by Firmware updaters built by Apple.

Firmware updates for Intel-based Macs require a GUID partition scheme

Trust this helps.

If you used SuperDuper or Carbon Copy Cloner, the GUID partitioning scheme is there and is working. Neither utility will function if it wasn't.

Cloning a hard drive to a new one causes the new drive to inherit all the fragmentation and errors of the old one. The best way to install a new drive is backup the old one via Time Machine and then restore to the new one during the installation. You'll probably find a vast improvement in boot time. Try it and let us know.

And also head into 'System Preferences - Startup' and select your OS X partition after a clone.

Thanks.. I have already repaired the disc permissions numerous times. Will also go and have a look at the partition preferences!

If not may rebuild and use my time machine for back up!

Thanks for all your help
