I have a late 2011 15" macbook pro. I've recently been using it at work and have windows 7 installed in Bootcamp. Two days ago I went to open my Macbook Partition and it just seemed to not be there. I know I should have backed up, but I haven't in two years. If I can't get at this I've lost two years of family photos. My little ones growing up, all gone. I'll be upset with myself for the rest of my life. So, I've got to fix it. The thing is Bootcamp works fine. It actually sees Disk E. But just calls it 'Local Disk (E)' and when I click on it it tells me it's not a valid file format and asks if I want to format, so I leave it well alone. If I start the machine it boots automatically into OSX Utilities and from there I can go to DIsk Utility. My macbook hard drive has become a grayed out disk0s2. When I click on 'Mount' nothing happens. When I run DiskWarrior it doesn't see or find the mac hard drive. I can open Terminal too, but I have no idea what to tell it. My only option seems to be to format. I dont want to loose my data. Arrgh!! I'm thinking there must be some basic level software corruption. Everything is still there, it just doesn't want to see it. I'm pretty sure I'm running OSX Mavericks. Please, any help would be great.
