    I have a late 2008 which just started to have problems booting up.

    The trouble started a week ago, when my MBP would shut down unexpectedly while I'm working(on battery power). When I tried to reboot from battery power it didn't work. However, it's not the issue of low battery level. I had plenty juice in the battery. So I attached to the mag safe power supply, it would boot up again.

    On yesterday morning after another unexpected shut down, I plugged the mag saft back in and hope it would boot up again. Never again. It will alwasy stuck at the gray screen with a spinning circle. So I did quite a few standard checks such as booting from Snow Leopard install DVD, and run DiskUtility. It tells me my MBP Hard Drive has problems and can not be repaired. So I figure it's the HD problem. Now I just want to salvage some data off from that HD, get a new HD and start over again.

    I tried to boot from DiskWarrior 4.2 DVD, it didn't boot up. It boot up fine with Snow Leopard DVD. So the optical drive works fine.

    The HD is the Hitachi 7200rpm travelstar 250GB.

    Any advice?

    You've given no real evidence that you have a hard drive problem. If anything, I'd be inclined to think you have a bad battery, as the symptoms you describe are one of the common ways batteries go bad on those machines.

    Clearly, your directory structure is corrupt, but it doesn't necessarily follow from this that you have a bad hard drive. If you ever turned journaling off, then this would be an expected side effect. Boot your machine in verbose mode. That is, hold down command-v as soon as you hear the chime. It will show text on the screen as it's trying to boot. If you see something along the lines of "disk0s2: I/O error," then you can assume you likely have a bad hard drive. Otherwise, you need to get booted to an OS from which you can run Disk Warrior.

    If your Disk Warrior disk is older than your machine, it won't be able to boot it. You need an OS that's at least as new as your machine. I don't know off the top of my head what OS was on the oldest DW 4.2 disks, but the fact that your machine failed to boot it is completely unrelated to the other two issues list.

    So I boot my MBP in the target mode and hooked it up to my Mac Pro tower. I can see the HD just fine and I backed up all the files from it. So I guess the HD spins fine. Now I should I repair it? I can run DiskUtility on my tower, erase everything on my MBP and start fresh. Or there's other ways I can do it without reinstalling everything again.

    Thanks

    Yes, run Disk Warrior. That's way better than Disk Utility.

    Did you see any I/O errors when trying to boot in verbose mode?
