I had the bad luck of turning on my laptop and it giving me the problematic symbol. My genius Bar friend said to reinstall the OS. So I did and now the partitioned hard drive is recognizing only one part of the partitioned drive. It see's the other part but will not recover in disk utility nor will it verify it. I've lost loads of important data but have a 2 month old Time Machine backup (Yes I know, lesson learned on that) but how do I get it to recognize the other partition? It's been 2 weeks and with only 32 GB of hard drive I'm dying. It won't let me restore from the Time Machine as there is not enough room. 🙁
