I installed an SSD (Samsung 830) as the internal drive of a Mid 2009 MacBook Pro, then attempted several times to clone the (now external) bootable OS X Lion drive using either SuperDuper or Carbon Copy Cloner to this new SSD. All attempts failed with disk writes failures (I tried two different SSDs with the same result: write failures). So installed Lion onto the new SSD using the OS X DVD installer and all went fine; then upgraded from Lion to Mountain Lion from the App Store. Again, all went great.
Which folders should I copy from the external Lion disk to the internal Mountain Lion SSD to get back all my apps, the MySQL server, PostgreSQL, ImageMagick, XCode installation, etc.? I would like to make the new Mountain Lion SSD contain all my useful apps so that I don’t have to reinstall from scratch.
