I thought I had read all the threads I could possibly read before making the move, but maybe I missed something... I have a 2011 15 inch MBP with a stock 750 GB HD. I bought a new SATA 3 Vertex 240 GB SSD and a Data Doubler. 1. I installed the SSD in the primary slot. 2. I used my install disk to install SL 10.6.7, then Software Update to bring everything up to date. No problems. It started, connected to the internet, all just fine, except none of my apps or settings. 3. I installed the 750 GB HD in the Data Doubler, then into the optical drive slot. No problems. I could restart and find both disks. 4. I had made a clone of my 750 GB HD onto an external FW disk using SuperDuper before starting all this. I now connected the FW drive, then used Migration Assistant to move my System, Library and Apps over to the SSD. I had created an admin account on the SSD with my first and last name. When I tried to use Migration Assistant, it asked me to change the name (since I had also used my first and last name on my 750 GB HD). So I created a new account with first name and last initial. 5. The transfer went fine. All my apps are available, and all my settings, at first glance, appear intact. 6. So now I follow all the previous advice I have read about, and go to Settings->Accounts-> Right click on my new user account (with just my last initial, not an admin account), Advanced Settings-> change my Home folder to the previous Home folder on my 750 GB HD in the Data Doubler, and restart. 7. Now it gets interesting. When I restart under my new user (last initial only), all my app settings are gone, I cannot access the Documents folder because I don't have permission, and I have no data. If I sign into my new admin account on the SSD (which has the same user name-full first and last name-and password as my 750 GB HD, I have all my settings, and can access the data. 8. So I don't know what I am doing wrong. If I go back and change the Home folder under my regular user account (with just a last initial) back to the empty Home folder on the SSD, I have all my system and application settings, but no data. Perhaps I am missing something really obvious here. I certainly hope so. I am pretty sure I haven't lost any data. Thanks in advance if you can point out how I missed something right before my eyes!
