Put the new drive in the external enclosure. Connect it to the computer. Partition and format the drive:
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-R keys until the Main Utilities menu appears on the screen..
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your external SSD drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Clone Lion/Mountain Lion using Restore Option of Disk Utility
     1. Select the destination volume from the left side list.
     2. Click on the Restore tab in the DU main window.
     3. Select the destination volume from the left side list and drag it
         to the Destination entry field.
     4. Select the source volume from the left side list and drag it to
         the Source entry field.
     5. Double-check you got it right, then click on the Restore button.
Destination means the external SSD drive. Source means the internal startup drive.
