I recently did a clean install and now I am attempting to migrate user data to the new install. I have a Mac Pro with four internal drives. OS X is on the boot drive, of course, and the user home folder I'd like to transfer is on another internal drive. (This is because I had moved all user directories from the boot drive to a separate internal drive in the Mac Pro. A consultant advised me to do this to increase performance.) I thought I'd be able to use Migration Assistant to simply migrate the user to the new install, but it appears you can only use MA with a Time Machine back-up or a disk with OS X installed. So what's the best way to move this user back?
