Formating Hard Drive for iMac

Posted on 2004-11-24

Hi I'm attempting to replace a failed harddrive in an iMac, but I'm having problems formatting the drive so I can reinstall an operating system.  When I put the drive in the machine and run the OS X 10.2 Install CD, it doesn't recognized the harddrive at all.  I'm assuming the drive may have come pre-formatted for Windows or something.  Anyway how can I format the drive for Mac OS Extended if I don't have another Mac around to do it from.?

Thanks for any help.

    When you say the installer CD doesn't recognise the drive, do you mean it doesn't appear in the list of destinations for the install? Have you run Disk Utility from the Installer menu?

    Should be recognized just fine unless it is a bad drive...

    If its formatted with anything else, it still should show up in the Disk Utility application....   boot from your CD and go to the File menu when the installer starts...  choose "Open Disk Utility..."; be sure your drive is there in the list on the left...

    If not, it’s either not powered up, or not working.

    If it is, partition it and format it with he provided utility.  Extended and Journaled files systems available.
