Using the dvd as startup I ran disk utility's repair disk and received messages that it can't be repaired, to back up files and install.

Some questions before I do:


How do I back-up my files when I can't see the drives?

Would the hardware test provide any repair help?

Can I attach it to my old MBP and start up while holding down 'T' to make it a fw drive and then transfer files?


In this install mode from my disc will I be able to choose the version that allows my apps to be saved or only clean install?

And when I reformat which format should I use?


Replies would be appreciated!




Here's the mesages I got::

Checking Journaled HFS Plus volume.

Checking extens overflow file

Unused node is not erased (node = 882)

Checking catalog file

Invalid mode strictire

The volume My Name was found corrupt and needs to be repaired.

Error: Dist Utility can’t repair this disk. … dis, and restore your backed-up fiiles


Then a window dropped down saying


Disk Utility stopped repairing My Name

Disk utility can’t repair this disk. Back up as many files as possible, reformat the disk, and restore your backed-up fil.




Any suggestions?

    I would try to back up to DVD if possible, you will need a trip to the Apple store. Possibly they can do a data migration, after finging and removing the corruption.  Maybe some one on this forum has a way, but I don't want to mess with your daat.  Best of luck

    You must be able to see the drive in Disk Utility. How else were you able to attempt to repair the drive?  You need to be a bit more specific about your current status such as: is the drive mounted on the Desktop? Can you then access the drive? Are you able to boot from the drive? If not, do you have current backup of the drive?


    The Apple Hardware Test is just that - a test. It performs no repairs.


    You may be able to repair the drive using Disk Warrior. To reformat the drive:


    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.

    Thanks for these replies!!


    I've had a problem where, when I used one of my mobile drives with my other MBP and then reattached it to this MBP it would cause sluggish performance. Something maybe to do with Apple writing files from the other osx. Usually after a few days it would return to normal performance. This time no. The drive was getting progressively sluggish in starting up till it wouldn't startup at all.


    So I started up from the disc (which is why I can't see the desktop, there's just a starry sky), ran disk repair and got the messages that it couldn't be repaired. However, I did run it on the name below the Mfgr's listing.


    After reading your replies I started up again. The SMART status does say VERIFIED. I selected the Mfgr.'s id entry and ran Repair Disk and received the same messages.


    So, from here, I can attach a external drive, it mounts, but I guess there's no way to backup files to it, right?


    The problem with using DW is I can't get my dvd startup disk to eject. Any suggestions?


    Is there a free trial for Disk Warrior?


    Thanks again for the reply, much appreciated!!

    Click on the Desktop then open Finder preferences from the Finder menu. Click on the General icon in the toolbar. Check the boxes to display disk icons on the Desktop.

    Thanks for the reply.


    As I said above, because I started up from the disc, I can't see the desktop, just a starry sky image that comes up whenever one's using the disc. So if I'm not mistaken I can't do what you ask, tho I very much appreciate your attempts to help!


    VERY IMPORTANT: How can I force the disc to eject? Otherwise, I don't see how I can use DW.

  • sanjampet Level 5 Level 5 (7,715 points)

    To force eject a disc, power off the machine, then hold your trackpad, or mouse button and power on, be patient as this can take a few moments, but the disc should pop out.

    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.

    Then where do you wish to go from here? Do you want to try erasing the drive and reinstalling OS X?

  • elmerlang Level 1 Level 1 (0 points)

    Woo hoo! Disc ejected. Thx guys!!


    From here? Since SMART says its verified, and so saveable, rt, I'm thinking DW. But if I can only download to my other computer how do I get DW to work on this computer? Can i burn the download to a dvd? Maybe I should buy DVD locally.


    You've been great help. Much appreciated.
