    I recently verified my disk through Disk Utility and found that it needs to be repaired. When I looked for instructions online, everything I found warned strongly that you must use an install disk of the current OS you are running, or else terrible things will happen. I am currently running OSX 10.6, but my install disks are from when I first got the computer, so they are OSX 10.5. Will terrible things really happen if I use this disk? Or should it be okay? I do not currently have the Snow Leopard install disk with me.
    Thanks so much!!

    The most effective repair that I have found is the command line File System Check run in Single User Mode:
    1. Restart.
    2. Press while the computer reboots.
      [*]Wait until the Mac boots into white-on-black fullscreen.
      [*]At the command prompt, type fsck -fy.
      [*]Wait until the OS returns the command prompt.
      [*]If repairs were reported, then repeat Step 4.
      [*]If no repairs were reported, then type exit.
      [*]Your Mac will reboot into the GUI and you are done.
