My computer is part of the hard drive recall and I have been putting it off. I just got a 2TB Seagate external drive for back up. I have it configured as the drive for Time Machine. My question is how do I back up this machine after the hard drive change? It was Snow Leopard when new and now I am running Mountain Lion. It took two hours for the initial back up, some 200 GB of info. How do I restore this machine after the drive is replaced? Will time machine restore the operating system and the dozens and dozens of updates including iTunes and a bunch of other non-Apple software? Any help appreciated. Thanks

iMac, Mac OS X (10.6.8), 3.2 GB Dual Core

    If you made the backup while you were running Mountain Lion, the most reliable method is to restore the backup through Recovery HD. See > http://support.apple.com/kb/HT4718


    To start in OS X Recovery, hold Command and R keys while your computer is starting and connect the external drive. Then, choose the option to restore a Time Machine backup and follow the steps. You can also use Migration Assistant, but it will create a new user and it could fail during the files transfer
