Hey, I have a white MB with 120GB HDD. I bought a new Western Digital 500GB HDD and would like to replace the 120GB. What i have now on my MB is what i exactly want on the 500 GB HDD. I don't want to install the OS again and then go with all the apps installation. I basically want to clone this 120GB onto the 500GB HDD and then replace it. How should i do it ? Second question: Is snow leopard really great as compared to leopard ? Because i have leopard 10.5.8 installed as of now. If snow leopard is worth upgrading to then i might go for a clean install of Snow Leopard on my 500GB.
