Hi all,

 

I am currently using time machine to back up a MacBook Air to an external 1TB hard drive.

 

The drive is partioned into 2 halfs as it backs up my iMac as well.

 

When I click on the Time Machine app or 'enter time machine', I am not greeted by the 'star wars' page, it just does nothing.

 

The back ups say 'last back up' and shows the latest back up being only recently, so it appears to have backed up correctly.

 

When I unplug the hard drive then click on time machine it says cannot find drive, as would be expected.

 

Any ideas?

 

Cheers,

 

Stuart.


MacBook Air (13-inch, Mid 2012), OS X Mountain Lion (10.8.1)

    Please try each of the steps below that you haven't already taken.

     

    Step 1

     

    From the menu bar, select  ▹ System Preferences ▹ Time Machine and make sure TM is ON.

     

    Step 2

     

    If you're backing up to an external hard drive attached to your Mac, open the backup volume in the Finder. You should see a folder with the name "Backups.backupdb". You should not see a file with a name ending in "sparsebundle". If you do see that, the backup was created over a network and can only be used that way.

     

    Step 3

     

    In the Finder, select Go Go to Folder from the menu bar, copy the text on the line below into the box that opens, and press return:

     

    ~/Library/Preferences/com.apple.finder.plist

     

    Move the selected file to the Desktop, leaving the Finder window open for now.

     

    Relaunch the Finder by selecting  Force Quit from the menu bar, then selecting Finder and pressing return. Your Finder settings will be lost.

     

    Try again to enter Time Machine. If you still can't, put back the file you moved to the Desktop, replacing the newer one that will have been created in its place.

     

    Otherwise, close the Finder window you opened and delete the file you moved to the Desktop. Recreate your Finder preferences.

     

    Step 4

     

    Launch Disk Utility and select the icon of the backup drive in the pane on the left (not any of the volume icons below it.) At the bottom of the window, you should see this:

     

    Partition Map Scheme : GUID Partition Table

     

    If the partition scheme is anything else, the drive has to be repartitioned (with the loss of all data.)

     

    Step 5

     

    Boot in safe mode by holding down the shift key at the startup chime. Try again to enter Time Machine.

     

    Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode.

     

    Step 6

     

    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

     

    Click the Clear Display icon in the toolbar. Try again to enter Time Machine. Post any messages that appear in the Console window – the text, please, not a screenshot.

    Step 2

     

    If you're backing up to an external hard drive attached to your Mac, open the backup volume in the Finder. You should see a folder with the name "Backups.backupdb". You should not see a file with a name ending in "sparsebundle". If you do see that, the backup was created over a network and can only be used that way.

     

     

    I am not at home at the moment, but I think this is my problem.

     

    The original backup was done over the network, but I have recently been plugging the hard drive directly via USB to do the backup.

     

    Does this mean the 'star wars' interface will only work if I open up the backup whilst the drive is connected to the network?

     

    Many thanks,

     

    Stuart.

    I've never tried the experiment myself, but the interface may work locally if you manually mount the disk image. It should mount automatically when the drive is on the network, rather than locally attached.

     

    I suggest you put this drive aside for now and start a new backup on another drive. You need more than one backup to safe anyway. When you're sure you'll no longer need the data on the first drive, erase it and start over.

    I'll try mounting the image tomorrow when I get home.

     

    I am in the process of obtaining a new drive to do everything on.

     

    I will let you know how I get on.

     

    Thanks again for the help.
