So I've started running out of space on my 250 GB HDD and I feel like it's time for an upgrade. So I figured I'd install Snow Leopard on a new 500 GB HDD. My Question is about the transfer of documents. I will be buying an external enclosure for the Drive I take out. So after I replace and install Snow Leopard, will I be able to restore my documents and settings from my old internal HDD? Will I have to re-install all of my applications? This is my first Mac so I don't know the details of these kinds of things. BTW, any suggestions for HDD brands/models? I had in mind a Fujitsu but not sure. I was just figuring if I replaced the OEM Toshiba with another Toshiba/Fujitsu I'd eliminate compatibility problems. Thanks for the help!
