    Open the Disk Utility and mount or repair the drive; if needed, format it as Mac OS Extended (Journaled). If the drive doesn't appear in the Disk Utility, it probably needs to be replaced but may have gotten unplugged.

    Clean Install of Snow Leopard


    Be sure to make a backup first because the following procedure will erase

    the drive and everything on it.


         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came

             with your computer.  Insert the disc into the optical drive and restart the computer.

             After the chime press and hold down the  "C" key.  Release the key when you see

             a small spinning gear appear below the dark gray Apple logo.


         2. After the installer loads select your language and click on the Continue

             button. When the menu bar appears select Disk Utility from the Utilities menu.

             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive

             size.)  Click on the Partition tab in the DU main window.  Set the number of

             partitions to one (1) from the Partitions drop down menu, click on Options button

             and select GUID, click on OK, then set the format type to MacOS Extended

             (Journaled, if supported), then click on the Apply button.


         3. When the formatting has completed quit DU and return to the installer.  Proceed

             with the OS X installation and follow the directions included with the installer.


         4. When the installation has completed your computer will Restart into the Setup

             Assistant. Be sure you configure your initial admin account with the exact same

             username and password that you used on your old drive. After you finish Setup

             Assistant will complete the installation after which you will be running a fresh

             install of OS X.  You can now begin the update process by opening Software

             Update and installing all recommended updates to bring your installation current.


    Download and install Mac OS X 10.6.8 Update Combo v1.1.


    If your hard drive does not appear in Disk Utility, then it most likely has failed or the ribbon cable for the drive has failed. In this case you need to take it in for service unless you know how to disassemble the computer, purchase, and install a new hard drive and ribbon cable.

    i tried going into the disk utility option and i can mount the drive. what pops up on disk utility is a DVD-R UJ-867 and its an optical device. the other option io have is the mac os x install dvd but all the options for it are blocked just like the the other option i mentioned first. what can i do?

    i cant back up the computer because it doesnt give me the option and i cant eject the cd because it wants to install but doesnt give me a hard disk or the cd option to install

    As I wrote above, if the drive doesn't appear in the Disk Utility, it probably needs to be replaced but may have gotten unplugged.


    Fixing either of these requires opening up the case and working inside. If you aren't comfortable with doing this, take the computer in for repair.

    There is no backup option in Disk Utility. You can remove the DVD as follows. But you might first just try pressing the eject button on the keyboard.


    Five ways to eject a stuck CD or DVD from the optical drive


    Ejecting the stuck disc can usually be done in one of the following ways:


      1. Restart the computer and after the chime press and hold down the

          left mouse button until the disc ejects.


      2. Press the Eject button on your keyboard.


      3. Click on the Eject button in the menubar.


      4. Press COMMAND-E.


      5. If none of the above work try this: Open the Terminal application in

          your Utilities folder. At the prompt enter or paste the following:


            /usr/bin/drutil eject


    If this fails then try this:


    Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
