I am running Snow Leopard and finally was able to download OS X Lion. However, it won't let me install as it says 'This disk is not formatted as Mac OS Extende d (Journaled). Use Disk Utility to enable journaling or reformat the disk.'


Is there a way to enable it without wiping everything clean?

MacBook Pro, Mac OS X (10.6.8)

    It told you what to do. Open Disk Utility and click the button icon in the toolbar to enable journaling. You don't have to reformat the drive.


    However, I would do this first:


    Repair the Hard Drive and Permissions


    Boot from your Snow Leopard 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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.


    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

    Actually I didn't see the "Enable Journaling" button! I only was looking in the First Aid/Erase, etc area. Then I just needed to restart installer. Thanks!
