Hi my hard drive is failing and I'm overseas in Thailand. I bought a Buffalo 1TB to back up my mac 13inch HD version 10.6.8, only problem is it wont back up. Disk Utility says ex HD is fine. I need to backup before I take it for repairs. What can I do? Thanks advice appreciated. NL

    Firstly, you need to prep this external drive as follows:

     

    Drive Preparation

     

    1. Open Disk Utility in your Utilities folder.

     

    2. After DU loads select the external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. 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.

     

    Next you want to clone your computer's drive to the external drive:

     

    Clone using Restore Option of Disk Utility

     

      1. Open Disk Utility in the Utilities folder.

      2. Select the destination volume from the left side list.

      3. Click on the Restore tab in the DU main window.

      4. Select the destination volume from the left side list and drag it to the Destination

          entry field.

      5. Select the source volume from the left side list and drag it to the Source entry field.

      6. Double-check you got it right, then click on the Restore button.

     

    Destination means the external backup drive. Source means the internal startup drive.

    Thanks I will try this, not always great at this but will attempt. Much appreciated for your time and quick response.

    Hi I followed your instructions after clicking restore, In the Source I had my HD of computer and in Destination I had my Time Machine backup disk, Firstly I unticked erase destination right under the Destination Box (I'm not sure if I did the right thing unticking it. Then disk utility said it could not restore input and output. Would you mind advising me further... Thanks

    You want to backup to the Buffalo external, correct? And, it is NOT your Time Machine backup drive, correct? I am under the impression that the Buffalo drive is a new drive not used for Time Machine.

  • nlouis4 Level 1 (0 points)

    I am attempting to clone my internal Mac HD to my Buffalo external HD, however it is the drive I use for Time machine Backups and that is it's name 'Time machine Backups"" This name was what I placed in the Destination Box as it wouldn't take the Top level 'Buffalo  1TB part of the name.

     

    for ex: In Disk Utility there ion the left hand side are names of HD or disks.

     

    Buffalo 1TB HD

       Time Machine Backups

     

    Hopefully you understand

  • Kappy Level 10 (265,883 points)

    OK. I did not understand that correctly. My suggestion is that you create a new partition on the Buffalo drive large eenough to hold all the data on your internal drive. Then clone the internal drive to that new partition.

     

    To resize the drive do the following:

     

    1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.

     

    2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.

     

    3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed.  (Note: You can only make a partition smaller in order to create new free space.)

     

    4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.

     

    You should now have a new volume on the drive.

     

    Clone using Restore Option of Disk Utility

     

      1. Open Disk Utility in the Utilities folder.

      2. Select the destination volume from the left side list.

      3. Click on the Restore tab in the DU main window.

      4. Select the destination volume from the left side list and drag it to the Destination

          entry field.

      5. Select the source volume from the left side list and drag it to the Source entry field.

      6. Double-check you got it right, then click on the Restore button.

     

    Destination means the new partition on the Buffalo drive. Source means the internal startup drive.

     

    If there is not sufficient space on the Buffalo drive for the needed new partition, then will need to get another external drive or rely on the Time Machine backups that you now have.

    Sorry but I am lost now, I thought I erased everything on the Buffalo as to your prior  instructions. My Buffalo is an external 1TB hard drive with the name Time Machine Backups. There is nothing on that disk. As My Mac hard drive is 500Gb shouldn't there be enough room? When I try to back up on time machine with my Buffalo ex- HD it keeps failing that is why I need another way to back up my mac. Do I have to have a partition on the external HD? I just want to back up my mac before I take it to repairs as I have no backup now. Thanks

    Regards

    I think we both had our wires crossed a little.

     

    Then just go ahead and clone your internal drive to your Buffalo. You are not going to use Time Machine, and you do not have to partition it. So ignore all that stuff I posted. Let me start from scratch.

     

    First check that your Buffalo drive is partitioned GUID and formatted Mac OS Extended, Journaled. So open Disk Utility, select the topmost entry for the Buffalo drive. You should see something like this:

    I have selected the entry of my CalDigit drive.  Note that the Partition Map Scheme is GUID. Now, select the volume (mine is "System Backup."

     

    Screen Shot 2012-12-12 at 10.25.08 PM.png

     

    Here you see it is a Format type of Mac OS Extended, Journaled. If that's what you see then you are good to go.

     

    With Disk Utility still open:

     

     

    Clone using Restore Option of Disk Utility

     

      1. Open Disk Utility in the Utilities folder.

      2. Select the destination volume from the left side list.

      3. Click on the Restore tab in the DU main window.

      4. Select the destination volume from the left side list and drag it to

          the Destination entry field.

      5. Select the source volume from the left side list and drag it to

          the Source entry field.

      6. Double-check you got it right, then click on the Restore button.

     

    Destination means the Buffalo drive. Source means the internal startup drive.

    Hi I am trying again with Time machine if it doesn't work again I will follow again your instructions above. However as I do that if the Buffalo is partitioned now there might not be enough space to backup? Is this correct? Thanks

  • Kappy Level 10 (265,883 points)

    OK, do it with Time Machine. Just leave your drive formatted as it was before you started all this. No extra partition.

  • nlouis4 Level 1 (0 points)

    Hi again, I retried time machine and did not work only backed up a few things so something must be corrupted. So from now I have some data on this Buffalo ex HD but still have to clone my mac HD before getting it repaired.

    Do I firstly have to erase all of the backup data before I begin to clone? What are my next steps before I begin cloning?

     

    Checked and all is good in the formatting Buffalo drive is partitioned GUID and formatted Mac OS Extended, Journaled.

    Cheers

    and thank you again

  • nlouis4 Level 1 (0 points)

    And if I have to Erase again  can I click the Buffolo 1TB on the left handside to place it in the (Name) box or the name below it Time Machine Backup?

  • Kappy Level 10 (265,883 points)

    I would say that the drive may be damaged such that it is no longer fully accessible, but you may try cloning it to the Buffalo drive using the procedure I've outlined previously. You don't need to re-erase the Buffalo drive as Disk Utility should do that before cloning.

  • nlouis4 Level 1 (0 points)

    Oh god, Hi, again, ........again I couldn't clone  my computer's HDas it said there was an input/output error. What to do??? I have no backup of my harddrive.?? Just can't back it up.....

     

    cheers

    Thanks
