Hi, My MacBook Pro recently crashed when I did a force shutdown, its very frusterating, it boots but there's a progress bar instead of the usual circling thing. After the progress bar completes, it shuts down. I tried Disk Utility by pressing cmd+r soon after the chime. It fails to repair the disk, And also can it remount. It says that it's unable to repair. I have some important files in the hard drive. So please tell me a solution to fix the hard drive without having to format the disk.
