I'm trying to install a new HD in my iMac G5. The origanal was corupted.  I go through all the motions and it starts the download and shows the HD with a red exclamation point and instructions that say I need to go disk utility and partion discs that does't fix the red ! . I am trying to install with an OS X 10.5.6 Retail Disc that I bought from apple after I loaned this out and came back without install discs.

Any help will be greatly appreciated.

Thanks Nelson

iMac, Mac OS X (10.5.6), I'm running the older OS

    I have no clue what you are doing, but here's what you need to do:


    Drive Preparation and OS X Install


    1. Boot from your OS X Installer Disc. 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.


    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.


    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.


    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.


    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.


    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.


    7. When formatting is complete quit DU and return to the installer. Complete your OS X installation.
