I had just rebuilt my MBP (2012) when the computer locked up completely. The partition seems to be screwed up. I had not backed it up yet, but I did have some new things on it I would like to recover as opposed to using my old backup. I can see the drive structure in the disk utility when I boot into recovery mode but I cannot figure out how to move the directories from the Mac to the external hard drive. I am missing out somewhere on a step or two (or three... four...) Pointers, anyone? Many thanks!
