Disk Utility: Restore Failure

I'm trying to restore my laptop from a dmg file. I have the laptop connected to another computer in target disk mode. When I try to restore, just after it starts copying I get this error:
Restore Failure
An error (2) occured while copying. (No such file or directory)
I created the image with Carbon Copy Cloner and hdiuti to make it UDRO formatted. The computer I'm using to try and restore it is a G5 tower running Mac OS 10.4.7 and I'm using Disk Utility version 10.5.6. Does anyone know why I'm getting this error? Should I convert it to some other format? Are there other ways to restore the disk that might work, if Disk Utility refuses to?

Sure you can... You mount the disk image on your Desktop. Run CCC. Select the disk image as Source Disk. Select the hard drive as Target Disk. Go (or Clone).
(also, CCC does not make disk images; it clones)

  • Disk Utility: Restore Failure-Source image needs to be scanned for restore.

    Hello guys,
    I have a .dmg (source image) that I have created from a DVD by myself (read-only format).
    I am trying to restore it to a destination and a Restore Failure notification pops-up as follow:
    "Restore Failure
    Could not find any scan information. The source image needs to be imagescanned/scanned for restore"
    I am quite new to Mac. Half of the time, I don't really know what I am doing - but just relying on the 'Help Menu', some research for guides on the internet and most of all read-on most of the posting here in the Apple Forum for what I want to do or might have encountered. Lastly to hopefully also speak the Mac language. For example - What's a disk image? What a .dmg? What's a source image? and etc. ~Lost~
    So for this case, I am totally lost as I can't seems to understand what does the Restore Failure notification mean at all as I quote above. What does it mean by the Source image needs to be imagescanned/scanned for restore? What do I do from there? How do I scanned my source image? Is there a steps that I miss out while creating .dmg from the DVD?
    Could not find any scan information? What scan information? Where do I go to asked for scan information?
    I am so lost that I don't even know the right question to ask or begin with.
    I know what I want to do and believe it can be done with Mac. But I just doesn't seems to understand the concept of how it really works yet but to just follow blindly throughout the guides.
    So please help me if possible.
    Thank you in advance.
    Best Regards,
    Jon Gan

    Hi,
    If you open Disk Utility, select the Image in the disk util sidebar, and click on Images > Scan for restore... in the menu bar, it will take care of it for you. After that you can perform a restore as you were trying to do.
    They do this so that disk util can verify your data after the restore to make sure it copied exactly.

  • Disk Utility: Restore no longer creates bootable images?

    So I have a new hard drive for my macbook, and followed the procedure I used last time of using disk utility restore to write the current hard drive image to the new disk, with the new disk in a USB enclosure.
    I have done this before, it creates a bootable copy on the new disk, swap the disks away I go.
    This time however the new disk is not bootable. When starting it gets to the grey screen with the rotating white pips then dumps back to a black screen with error messages (like its trying to boot of the network).
    Swapping back to the old disk boots just fine, so its a problem with the image written to the new disk by disk utility restore not being bootable.
    Is this a known issue? I searched the forum with no answers, and am frustrated that its now working as I have run the image twice now at about 5 hours a go for 100GB of data so I am sure its not the copy. Straight after the copy the original disk has about 10 more files than the new disk that's just been imaged, has their been some update to disk utility in the OS X patches that means it no longer copies some key files?
    Note that partition on new disk is GUID as it should be, and I don't want to re-install anything from the install media I want to use make disk utility work as designed.

    I found two references that may help:
    A) At http://everythingapple.blogspot.com/2007/11/use-powerpc-mac-to-create-bootable.h tml it says "PowerPC Macs use the Apple Partition Map, but this poses no problem for Intel Macs, even though Intel Macs use the GUID Partition Table. The reverse is not true however. PowerPC Macs cannot boot disks with a GUID Partition Table."
    1. Open up Disk Utility and select your backup drive. Select the "Partition" tab.
    2. Go to the "Options" and choose "Apple Partition Map", which is the partition type necessary for PowerPC Macs.
    B) Carbon Copy Cloner - Red Dot Warning on main screen: "The target volume will not boot this computer because PowerPC Macintoshes cannot boot from USB devices."
    Looks like I'll have to install the 2.5" SATA drive into my PowerPC MacMini to upgrade my system volume from 80gb to 320gb.

  • Disk Utility Restore - Why error -34 ?

    I cloned my 700 G3 iBook's 20GB hard drive to a 30GB ext. HD with Disk Utility>Restore before sending it for repair. Now that I have gotten it back I want to restore the data to the computer's HD. I'm getting error -34 (disk full).
    So what is the nature of my problem? Must the destination disk be at least as big as the source disk? (Because it is copying the entire 30GB size.) Or must I empty (erase, reformat) the destination disk? (Because it is adding the data to what is already there.)
    Thanks

    Michael:
    You were right. Thanks. The data would have been added to what was already there.
    While I had made back-up clones before, this was the first time I needed to put it back into the computer's hard drive.

  • Disk Utility Restore

    I copied my macbook pro's hard drive to an external drive using disk utility restore. Is it normal for the copy's overall size to be smaller than the original? I thought it would be the same size? The external had no data on it. The original is 273.54 GB and the copy is 271.45 GB... Problem?

    May I try to answer your question. When you copy a disk there are a number of files which are not copied such as Trash, swap files and any temporary files that may have on the old disk will not be copied to the new disk. So while the approximately 2 GB of data might at first glance seem like a lot, it is in fact not really that much. I hope that helps you to understand what is happening there.

  • How to clone disk (Disk Utility Restore, boot: kernel panic)

    Hi, I've tried two times to clone my 120GB system disk (old Core2Duo Mac Mini (macmini2,1)) to a 1TB disk attached via USB cradle. Running Snow Leopard 10.6.8 which long time ago was upgraded from Leopard.
    Used the Disk Utility "Restore" for cloning. Both times Disk Utility completed without errors. However when I swap the 1TB from USB cradle into mac mini (to internal SATA), the result of even a "Save Mode" boot attempt with Shift/Mod key held is always a kernel panic: "unable to find driver for this platform: \"ACPI\"
    As my goal is to clone the existing system to a larger drive, a new install of OS X on the 1TB drive is out of the question. The original 120GB disk boots without problems. But the cloned attempts do not boot.
    Judging from the kernel panic it is as if "Restore" doesn't actually restore, but leaves out files. Thus Disk Utility restore in SL is buggy?
    Or is my cloning method wrong? Currently I just drag the 120GB system disk (the live running system) to the Source, then drag the 1TB USB disk to Destination, and allow full erase of destination, and do the priviledge elevation to root i.e. the usual password prompt. Does successful cloning need something extra...?

    If I understand correctly, what you're doing is copying your 120 GB drive to the 1 TB drive, then swapping the 1 TB drive into your Mac and trying to boot from it, and it fails.
    You're doing it wrong, and that's why it fails. A Finder copy (what you're doing) does not respect permissions or symbolic links, which are required to make the system boot. You need to use something that does respect that.
    Get your hands on a copy of SuperDuper http://shirtpocket.com/
    (free for basic use, but it's well worth the small fee of $27.95 for full access to all features); and/or
    Carbon Copy Cloner http://bombich.com
    and use one of those to make a bootable clone of your 120 GB drive, then you can boot from it.

  • Disk Utility - Disk Image Restore Failure

    Hi folks, when trying to restore a disk image I have had the error message:

    It will be noted that this is an OS9 image, I've made a small partition just for running Reason/Rebirth.
    But I don't think the fact it's OS9 should be an issue.
    The current main start-up disk is a OS X clone made by CCC on a Western Digital 250gb HD, but the above problem on the source disk Disk Utility was the reason I used CCC to clone in the first place (if you see what I mean).
    I'm trying to avoid putting the old disk back in but I will if I have to : I am assuming that the problem was on the source disk therefore I can deal with it on the OS X clone.
    Cheers if anyone can shed some light,
    Steve B

    Yes I do have access but I'm afraid I blew the firewire bus on this TiBook last year (noted elsewhere in the discussions) so can't do target mode. Twas a terrible blow to an otherwise mint book...
    I have been using it since & the damage seemed to be limited to the lack of firewire & inability to sleep.(the laptop not me!!!)
    I'm not yet in the position to buy a new book (or even a £200 logic board which is the only way of restoring the firewire (which I might do yet as I am a Rebirth fanatic & it only runs on OS9)
    The only way I can remotely work on this is by removing the disk & putting it in one of my enclosures.
    As a matter of interest what action were you going to suggest?
    Cheers,
    Steve

  • Disk Utility Restore Process Input/Output Error

    <Image Edited by Host>
    My niece's MBP specs above. If I posted a picture of this poor machine, there'd be a lynch mob of passionate Apple fans arrive at my door wanting a public hanging...It's been dropped no less than a dozen times. (The ethernet port is stretched out of shape so badly that a standard plug will no longer fit the port!!!).
    Among other physical injuries, the screen won't present an image (just flickers white lines on black background, hinge has partially detatched, suspect the ribbon that transmits the display signal has been compromised). A visit to the Apple store tells us (by plugging into a cinema display via TB) that the hard drive is still in tact and data is salvageable. Keyboard and trackpad both work fine (surprisingly).
    Long story short, she's acquired a new MBA, been read the riot act about looking after it, and I have the unenviable task of salvaging her data, approx 275Gig.
    My objective is to obtain:
    1. A full copy of the data (existing file structures) - Complete
    2. A bootable disk image of the MBP - Incomplete and troublesome
    I have at my disposal:
    Mid 2011 27' iMac (Intel i7) on Mav
    MBPr13 (third host if needed) on Mav
    A home ethernet network with enterprise grade switching
    A Lacie 5BigPro 10TB NAS
    A couple of 1 & 2 TB Toshiba external drives, and
    Enough network adapters, USB cables and thunderbolt cables to suffice. Admin priviliges all round. All disk permissions repaired.
    Current connection config is the MBP thunderbolted to the iMac. I can use TDM (if I need to interface with the MBP using the iMac display) or can boot in Target Disk Mode if I want to see the MBP disk image on the iMac.
    Regarding Objective2: A bootable disk image of the MBP, I first tried to use the Restore function in Disk Utility, but that only works when booting the host in Recovery mode, whcih doesn't support TDM, so I'm flying blind...
    Next try, I booted the MBP in Target Disk Mode, which allowed me to use the Restore process from the iMac's Disk Utility, select the MBP HD, and target an external drive (one of the Toshiba's) plugged in to the iMac via USB.
    I've now tried this Restore 3 times, each time getting the following I/O error (at about 45 munites in to a projected 4 hour process):
    Any thoughts on root cause?
    And (given my screen/display limitations) am I missing a far simpler option?
    Cheers, Sla

    If that were the case you would not get in/out errors. These errors occur because the drive is no longer able to transfer data which is a hardware failure.
    If you want to post an image to the forum then you need to open the message editor and click on the Camera icon you will find in the editor's toolbar. Then select the image you wish to post and click on the Insert button.

  • Disk Utility Restore Problems

    Hello All,
    The Boot Camp Assistant told me that I had to reformat my hard drive as Mac OS Extended (Journaled) so I:
    -Cloned the drive with Carbon Copy Cloner,
    -Booted from my external hard drive, and
    -Erased my internal disk (Using Disk Utility).
    Now, when I try to restore (using Disk Utility) from my external to my internal drive, I get one of two errors:
    -RESTORE FAILURE: Lost connection to helper tool.
    -RESTORE FAILURE: Could not establish connection with helper tool.
    Does anyone have any idea what's going on? I've gone through this whole thing once before for Boot Camp, but the last time didn't yield any crazy errors...

    This sounds odd, you normally would only need to create a new partition for BootCamp, rather than erasing the entire drive.
    I have no idea what is going on to produce those error messages, nor can I find much information with Google - which is unusual.
    So the following is based on my best guess.
    When you erased the volume, did you set the partition table to be GUID? This is required for Intel Macs. It might be worth repartitioning the startup disk, and making sure that you have the correct options all the way through for your OS X partition:
    HFS+ (Journaled)
    GUID
    (No OS 9 drivers)
    Once this is finished, exit Disk Utility.
    To restore your clone, use Carbon Copy Cloner from your external drive, and simply back the external drive onto your newly formatted internal drive.
    Once CCC has finished, then you can run Boot Camp - and follow [these instructions|http://manuals.info.apple.com/en/BootCampInstall-Setup.pdf]. You don't need to erase your entire Mac Hard drive, the Boot Camp Assistant will create a new partition for Windows.

  • Disk Utility restoring a disk, What do I do?

    Hi,
    I had a problem with my Macbook Pro being stuck in a grey screen at start up. I've worked through available info online and I have now run my install disk. Under Disk Utility / First Aid. No problems are showing on my Mac OS X start up volume. How do I move forward now. If I restore my volume, will I wipe files that have not been backed up to Time Machine?

  • Disk Utility Restore from Sparse Image taking forever

    I created a sparse image backup of my MBP C2D using SuperDuper! before sending the laptop back to Apple for repair. I wiped the drive clean before shipping. I now have the laptop back and am trying to restore the sparse image to the HD.
    The sparse image file is on an HD in my G5 tower and is just over 108 GB. I booted the G5 into target disk mode and connected it to my MBP via FW800. I then booted off the Leopard install disk and launched Disk Utility to do the restore.
    The sparse image mounts fine in Disk Utility and is specified as my source for the restore.
    I started this restore last night before I checked out for the night and when I got up this morning, Disk Utility showed about 35-40% of the image had been restored and 14 HOURS were remaining. That seems a little excessive after it had already been running for well over 9 - 10 hours.
    The sparse image mounts on the MBP just fine using target disk mode from my G5 -- so as far as can tell, my backup image itself is ok.
    My question is this: is the Restore function performance of Disk Utility with sparse images really this bad or is something wrong with what I am doing? I really don't want to rebuild my laptop from scratch, but if I have to wait 34 or more hours for Disk Utility to finish a restore -- it might be quicker to rebuild it.
    Any ideas out there?

    no the restore function is not this bad.
    something must be wrong with your sparse image. you should have tested it before sending the computer for repairs. and why did you use a sparse image at all?! you should have made (and tested) a standard clone.

  • Disk Utility - Restoring a previous image

    Since I first bought my Mac Mini (February of this year) I've been using the disk utility to make occasional backups (disk images) of my partitions, in case I ever need to restore a whole partition (or create a clone of an existing partition - for example, so that I could test some new software that might cause problems). I've never actually needed to restore a partition (or produce a clone from one of the backup images) until today. However, when I first bought my Mac I did test this feature and it seemed to work.
    A few days ago I realised that I'd soon need to clone a partition so I backed up my Mac HFS partition which is about 90GB in size (my internal disk being 500GB). I then used Coriolis iPartition to create a new, empty Mac HFS partition of the same size, then tried to use Apple's Disk Utility to restore the newly created disk image. However when I came to try the restore, I got an error saying that the image would first need to be "image scanned" before being usable. I then tried an old image that I created when I first bought the Mac and currently, that one seems to be restoring.
    AFAIK I've used the same method to create both images so why did the old one work when the new one didn't??
    Message was edited by: johne53

    Hmmm.... I've just realised that none of the images I've created recently will verify properly. They all get to the end of the first stage (block checksum of partition #1) and then fail with "internal error". The only one which passes the verification process is the very first one which I created a long time ago. That one seems to complete two stages of block verifications (for 2 partitions) then one "file checksum".
    If I try to select a disk image and use "Open Disk Image" (from the right-click menu) I get an error saying "Unable to attach [image-name].dmg. No mountable file systems." This happens with every disk image I've created, apart from the very first one.

  • Disk Utility "Backup Failure"

    Hi all -
    I have a 500GB iMac running 10.6.8.  I am trying to save a bootable backup on my new WD MyBook Desktop 1TB hard drive using Disk Utility (11.5.2).  I have formatted the WD with 2 volumes, one of which (named "Boot2") is to be my bootable backup.  But when I try to duplicate my "Macintosh HD" volume into Boot2 using Disk Utility's "Restore" function, I get an error message stating "Restore Failed - Operation not permitted" (or words to that effect).
    I did the following:
    1 - Formatted the WD drive into 2 500GB volumes using Disk Utility with Mac OS Extended (journaled) format.
    2 - Selected "Macintosh HD" volume in DU's left hand column, and clicked the "Restore" buttton up top.
    3 - Draged "Macintosh HD" (the volume) into the Source window, and draged "Boot2" (my WD backup volume) into the Destination window.
    4 - Clicked the "Restore" button in DU's lower right corner.
    At first, the operation seemed to be going normally.  But after copying "Appleworks 6 Updater Log", the "Applications" folder (with all the apps), and a "Backups.backupdb" folder, it stopped and gave me the error message.
    Any thoughts as to what's going on?  What kind of operation would be 'not permitted'?  Did I do something wrong?  Or am I missing something?
    Thanks in advance for any thoughts.
    - The OldFart

    Try it this way:
    A. 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.
    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.
    B. Clone using Restore Option of Disk Utility
      1. Select the destination volume from the left side list.
      2. Click on the Restore tab in the DU main window.
      3. Select the destination volume from the left side list and drag
           it to the Destination entry field.
      4. Select the source volume from the left side list and drag it to
          the Source entry field.
      5. Double-check you got it right, then click on the Restore button.
    Destination means the external drive volume. Source means the internal startup drive.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.

  • Disk Utility "restore" fails with "no such file or directory"

    Some time back, perhaps a LONG time ago, I successfully used Disk Utility's "restore" function to "clone" my Mac OS X partition onto an external disk, before I upgraded the OS on my internal drive.
    This weekend I tried to do it again, and failed on every attempt.
    My first attempt was on my MacBook. At very end (the progress "bar" was all blue) it died saying that there was an error (2), "no such file or directory". I think the external drive probably isn't GUID, which would make it non-bootable, but I'd still think "restore" itself should work.
    Okay, let's try my Power Mac G5, which is where it worked several releases ago. Same thing.
    Okay, one more try... Booted into safe mode (in case background activity accounts for the missing file/directory), did the restore again, failed again.
    I realize that SuperDuper or Carbon Copy Cloner or other tools may be "better", but since this worked once it seems like it still should.
    Any ideas?

    B. Erase the destination drive before cloning?

(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. Now shutdown the computer for a couple of minutes and then restart normally.
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) 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.
    How to Clone Using Restore Option of Disk Utility
    1. Open Disk Utility from the Utilities folder.
    2. Select the backup or destination volume from the left side list.
    3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
    4. Click on the Restore tab in the DU main window.
    5. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
    6. Select the startup or source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    8. Select the destination drive on the Desktop and press COMMAND-I to open the Get Info window. At the bottom in the Ownership and Permissions section be sure the box labeled "Ignore Permissions on this Volume" is unchecked. Verify the settings for Ownership and Permissions as follows: Owner=system with read/write; Group=admin with read/write; Other with read-only. If they are not correct then reset them.
    For added precaution you can boot into safe mode before doing the clone.
