Hi,

 

In a previous post I asked about running Snow Leopard on my mac after a hard drive fail. I'm having issues with formatting a new hard drie in my mac. I have a 2007 black macbook and I'm trying to run a 160gb SATA seagate hard drive.

 

After replacing this hard drive, I booted my mac up from cd, ran through setup fine until I got to the 'select a devide to install to' - the point where my hard drive should be visible. Nothing there at all. Nothing to click on in the box....

 

My question is, is there a process I need to undertake to format the hard drive or is this an indicator of a much bigger problem?

 

Thanks

    Yes, there is. Use the Disk Utility in the Utilities menu to erase it.

    Drive Preparation

     

    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.

     

    You can install OS X once formatting is complete by quitting DU and returning to the installer.
