usually, when i reinstall a fresh OS on my MacBook, i do: 1. Reset the PRAM *. turn on your Mac+Hold down the Option+Command+P+R (hold it down till the 3rd reset 2. after the reset (I'm assuming that the NEW HDD is installed) insert the OS CD for Leopard or Snow Leopard) *. turn off Mac *. Turn it back on 3. hold down Option wait until the screen displays the HDD icon and the CD Rom option (usually, u dnt need to do this for Blank HDD) and let it load 4. once loaded, on the top you will see the Mac Utilities option. *. Select Utilities and Disk Utilities to Format the HDD using Mac OS Extended (Journaled) 5. after format, close Disk Utility and move forward with the installation.
