Hi all, Yesterday morning my PowerBook suddenly emitted a weird chime sound, and the hard drive started clacking, and the computer froze not long after that. It wouldn't reboot and I thought I was screwed (hadn't backed up in awhile...) I found that if I tilted the computer 30 degrees on its side, the hard drive would function and I could boot and operate the computer normally. So I quickly copied my important files, and then cloned the entire hard drive to a spare 2.5" drive. I'm going to get the bad drive replaced under warranty (from Newegg), but tried sticking in the backup drive for now. Problem is when I boot up, the computer gets to the gray Apple screen, and freezes. Has anyone cloned their startup HD with Disk Utility and able to boot off the copy? I have the OS disk at home, and will boot from it later and try to repair permissions, etc. But I'm just wondering what my chances are that I can get this drive to boot. Any tips/feedback/similar stories would be much appreciated!
