Hey MacRumorians, I've never run into a Mac problem I haven' been able to fix, but this one seems to be troubling me. I have a MacBook Pro running Snow Leopard. The battery says "Replace Soon", but usually works fine as long as it's plugged in. The other day I was messing around with PathFinder, a Finder replacement, and I may have accidentally messed with some permissions by quitting and restarting Finder so many times. Anyway, it won't boot now. The Apple logo shows up, then an empty loading bar appears, and then finally the spinning wheel. The bar stays empty, disappears, then it stalls on the logo and the spinning wheel. Looks like this but empty: ] I have the Mac OS X Install DVD and DiskWarrior, but it won't boot from CD/DVD. It won't boot in Safe Mode or Target Disk Mode. When I boot into Single User Mode and run FSCK, it says "Macintosh HD could not be repaired". Any idea how I can get my files back or go about formatting and reinstalling?
