OS X :: Disk Utility Restore .dmg Backup File

Mar 4, 2010

I'm trying to use Disk Utility to restore a .dmg backup file stored on an external usb hard drive. The image is a read-only dmg and is 75gb. When I try to restore the 75gb image to a 128gb SSD formatted in OS Extended (Journaled), Disk Utility says that there is not enough space on disk to restore.


OS X V10.7 Lion :: Disk Utility Starts When Clicking On DMG File

Mar 25, 2012

I don't know if this is a problem or not, but recently on my 15" MBP using Mac OS X Lion 10.7.3, clicking on a .dmg file automatically opens Disk Utility. Which is weird, since before this situation happens, opening a .dmg file will not automatically open Disk Utility.I have a screen shot below opening the .dmg file for Firefox installer for Mac OS X. Shouldn't it actually be like this when clicking on a .dmg file? Is there a problem with my MBP or my Mac OS X Lion?

Windows On Mac :: Bootcamp Backup Via Disk Utility - Restore With Or Without Deleting Partition?

Jun 23, 2009

I would like to "Back-up", "Clone" or create an "Image" or whatever else people call it of my bootcamp installation. I know I can create an "Image" of bootcamp via disk utility but how would I restore it?

Would I first delete the bootcamp partition and then re-create a bootcamp partition and then restore? Or would I just restore? Will the end result be what I am expecting, i.e., my Win 7 install right back to the perfect state of when I created the image?

Right now, let's say my Windows 7 install got smoked one day for whatever reason (it is windows...) and I needed to re-install. Me personally, I would just go into Bootcamp Assistant, delete the Windows partition then create a new one and then get installing. Unfortunately installing and updating takes hours and that is what I am trying to avoid.

OS X V10.7 Lion :: Disk Utility Showing A Dmg

Apr 9, 2012

I was going to run Disk Permissions and when I opened it up, there is a decrypted file.dmg showing. Here is it's path:/var/folders/2d/vmlqi1 d0gzcs7mxi nnl 1w0000gn/T /decryptedFile.dmg...I opened it and saw that it has something to do with installing Adobe Flash Player. I remember downloading and installing it a couple of days ago. I've adonw this previously, but never had the disk image show up in Disk Utility before. How can I get rid of it? It seems to be in a folder calledl "T" that I can't find anywhere.

OS X V10.7 Lion :: Cannot Restore DMG Image Stored On NTFS Disk?

Apr 10, 2012

My MacBook Pro has OSX Lion on it. I have created a DMG image of my starting volume using Disk Utility. The image was saved on an NTFS formatted external USB disk. I used Paragon NTFS for Mac to activate writing on NTFS partitions. The image was created, tested and it mounted fine. It's size is 105GB. 

I have restarted the system and am accessing Disk Utility from the recovery partition that OSX Lion creates. Disk Utility can see the NTFS disk and I can choose the DMG image as source and the partition on the internal hard disk as a target without problems but when I press the restore button and the Image scan process is going to start I just get an error that says "Unabke to scan Mac-OSX HD. Resource busy". When I try the SCAN BEFORE RESTORE command on Disk Utility on the image I am getting "Unable to scan MAC IMAGE.DMG (Not such file or directory)". 

I have already erased my startup disk and really need to get this image back in place. It is the only backup I have of my data.

OS X :: Can Disk Utility Restore The New IMac?

Aug 16, 2010

I am now using a mid 2009 imac (i5 27") and will be getting the updated mid 2010 imac (15 27").

My question is; can I use a disk image of the 2009 imac and put it on the 2010 model to minimise the switching effort? I know some programmes will have to be reinstalled and I will need to unregister some things like Quark and iTunes.

Is it true that you have to make the disk image while the system has started up with the OS X DVD?

CCC warns that the image it makes will not be bootable. Can Disk utility restore the new iMac from it?

OS X :: Disk Utility Restore Feature In Jaguar?

Apr 15, 2010

just got a cheap ass emac off ebay and it came with 10.2.4. I am trying to restore a DMG file to a partition. In Leopard it can be done using the Disk Utility by using the restore tab and selecting the image. This option is not available in the Jaguar disk utility but I think the feature is still in the OS only command line, is this true? and if so where would I be able to get some help on this matter.

MacBook :: Disk Utility Can't Repair 2011 - Saying "disk And Restore Your Backed-up Files"?

Apr 2, 2012

My Macbook crashed so I tried everything to restart it.  what finally worked is opening it from the install disk.  I performed a "repair disk", and after saying "invalid node structure" and "invalid record count", it says it cannot repair the disk.  I don't know what step to take next.  How do I see if time machine has backed my files up?  Do I need to erase the HD and reinstall?

Applications :: Disk Utility Won't Restore?

Jan 4, 2011

I have a sparse disk image that is 10+gb, however the files on it amount to no more than 4.4gb.

When I try to restore to another sparse image that is 4.5gb or even 4.8gb, it says to me that there is not enough free space.

The files are only 4.4gb! How the hell do I set Disk Utility straight? Or is there another app that could accomplish the same thing?

Why god WHY has Disk Utility been broken since Leopard and let to remain broken??!!

OS X V10.7 Lion :: Can't Restore Partitioning Using Disk Utility

Apr 8, 2012

I'm trying to restore the partitioning of my late 2011 Air drive, after messing it up while trying to dual boot OS X and Linux. The goal is to get rid of the superfluous partitions and resize the OS X one so I can use the whole drive again. Data loss is not an issue. According to Disk Utility the partitioning looks like this: 

Macintosh HD
Recovery HD

Software :: Unable To Open Dmg File - Moved To External Hard Disk

Jun 9, 2009

I created an image of an external hard drive to back it up, then I checked it and it opened fine. I moved the file to another drive and initialized the original drive and dropped the dmg file back onto the drive. Now it won't open. I really need the files on that drive. Is there any way at all to open it if even for a short time to retrieve the files?

OS X Technologies :: Restore Multiple Partitions Through Disk Utility With Apple-script?

Apr 13, 2012

I need an AppleScript to restore a bunch of partitions from a master drive to a stack of external target drives. I don't mind partitioning them 1st, if necessary.The master drive has 16 partitions, all equally sized, and I'd like a script to run that will have Disk Utility to just go down the list restoring each partition to the matching 16 partitions on one of the target drives.

OS X :: Partitioning With Disk Utility For Storage And Backup

Jun 25, 2009

Here's my setup:
One, dual bay enclosure (1.5TB x2):
OWC Mercury Elite - AL Pro Dual Bay Enclosure
and one, two pack of 1.5TB Seagate HD
Total: paid $310 including shipping for the 3.0TB external setup.

I'm going to use FW400(since my MB pro has no 800 port) and partition this into two 1.5TB partitions. one for storage, and one for time machine backup. My question is if I choose 2 partitions in disk utility, will it automatically know to use one of the 1.5TB Seagate HD for one partition and the other 1.5TB seagate for the 2nd partition? Or will it use half of one and half the other? I would like one partition to be one seagate 1.5TB HD, and the 2nd partition to be the other, that way if one fails I have a backup (using Time Machine with one partition to backup the other 1.5TB drive).

OS X :: Hard Drive Backup - Do Not Have Disk Utility

Jan 4, 2010

I am going away traveling and need to back up all my stuff off of my mac for the first time.. (pics, music etc the usual). I brought a WD Elements 500GB External Hard Drive and when I plug it into my mac book (OSx) it appears in finder, and the desktop but I can't drag and drop nothing into it. Apparently I have to format it! So have researched about formatting it, but I don't have "Disk Utility" in my utilities? My Mac was given to me from a friend second hand so i don't have the disks etc to get it. Any other way of formatting my Hard drive or a link to download disk utilities or any alternatives!

I have to erase my HDD, due to a problem in the booting. It gets stuck at the grey logo screen. I�ve tried all possible solutions, but to no solution. So, i was wandering if it is possible to make a copy of some of my work files to an external hard drive trough Disk Utility, since my external HD doens't have enough space. Also, i�ve noticed that i only have acess to certain system files, trough the disk utility. No desktop folders or aplications.

Applications :: Disk Utility File Too Big For CD

Oct 20, 2009

I am fairly new to the Mac world. The other day I was trying to do a disc copy of a music CD. I followed the instructions within Disk Utility, which resulted in a .dmg (disk image) file being created. However, when I went to burn the resulting file to a blank CD I found that the file was bigger than the capacity of the CD. Obviously, the disk image file itself takes extra space (in addition to the size of the original music files). Is there any other way of creating a 'snapshot' of a CD or DVD? Perhaps 'on the fly', as I do with my PC's?

Intel Mac :: Disk Utility Can't Repair HD - Possible To Create New Image To Backup?

Jun 7, 2012

Two days ago my computer died and I haven't been able to get past the Apple screen since. I've tried starting in Safe mode, etc. that did not work. I just started up using my installation disk and got into Disk Utility. It says it cannot repair the disk and that I should back up as many files as possible and reformat the disk. How am I supposed to back up if I can't start up? I am currently creating a new image of the HD to an external drive but my question is if Disk Utility couldn't repair the disk, with the external drive copy also be problematic? How can I tell before I reformat the whole thing and start over?

OS X :: Cannot Burn A Bootable Image File Using OS X 10.3.9's Disk Utility Software?

Feb 21, 2009

I'm currently trying to burn a bootable image file using OS X 10.3.9's Disk Utility software. I have an external DVD Burner connected to a G4 Cube via Firewire. The issue is that when I select "burn" from the menu and point to the respective .dmg file, Disk Utility does not recognise the attached DVD burner. The burner is however recognised in Toast (which I also have installed).What might the issue be? I have searched high and low on the net in an attempt to diagnose the issue to no avail. Is there an alternative solution to burning bootable disks in 10.3.9?

OS X :: Won't Work With Disk Utility / Sending File Too Large Error

Dec 30, 2009

I am trying to create a new image from a DVD and burn it to a new DVD using the MAC Disk Utility "New Image" option. The source DVD is 4 G and my target folder is on my external HD which has 298G.. plenty of space. However, whenever I attempt to SAVE the existing DVD to my external HD, I am getting the error message that the file is too large. I have tried the parameter for "Image Format" of both 'Read Only' and 'DVD/CD Master' and neither of them work. My "Encryption" setting is 'None'.

OS X V10.7 Lion :: Disk Utility Restore Put Recovery Hd Over Mac Hd After First Properly Copying Mac Hd?

Apr 4, 2012

I am trying to make a redundant backup image of my harddrive using something OTHER than Time Machine.  I booted to recovery because you image from a disk you are booted from.  The restore took 2 hours, and indicated the entire time in disk utility that it was restoring "Mac HD" to a similarly sized partition on my external hard drive.  When it was done, the external had a copy of my recovery drive on it.  That's crazy talk.

MacBook Pro :: Trying To Burn A .cdr File To A Dual Layer Dvd Using Disk Utility?

Jun 28, 2010

I have been trying to burn a .cdr file to a dual layer dvd using Disk Utility. I got it to work once, but I tried four times. I think that it must be very sensitive or something, because I can't figure out any other factor that affects it.

Has anybody else run into this problem, and if so, what's your solution? I think it may have to do with vibrations of the disk drive or something, but I would be lying if I said I knew that for sure...

Hardware :: Running Disk Utility - Moving BIG File On External Hard Drive

Dec 23, 2007

Will running the 'repair disk' disk utility on an external drive screw up any of the files on my external hard drive? I only want to run it because I can't transfer a file from my HD to the external...it's a 6 gig video file in quicktime format, and I'm getting 'error 1309', which I understand is related to file size on FAT32 format. I know it's a huge file, but I've moved others to the external that are over 20 gigs with no problems (iMovie projects, etc). Anything I can do to get this file moved to the external?

Hardware :: Time Capsule Backup Size Smaller Than Disk File?

Jun 20, 2009

I have been using time capsule for only a few weeks and I have noticed that the file it has created "Elliot Newman's MacBook Pro_001b63936847.sparsebundle" only reads a file size of 95GB, when the disk I am backing up has 148GB used. Does this mean the backup doesn't contain all my files? I have to say it concerns me a little that the backup shows only a single file, is there anyway to see the files that time capsule has backed up? I am updating my MacBook soon with a bigger internal drive and I want to make sure all my files are backed up before I do this.

OS X V10.7 Lion :: How To Restore User Without A .dmg

I inadvertantly deleted a user that has some needed information.  I did not elect to to create a compressed version of the user (wish I had) but I also didn't tell it to delete the user immediately. I selected "don't change the home folder" when deleting the user.  I know where the user home folder is but I cannot access it.  I am also nearly certain that the data is still intact because the Hard drive is far too full to be explained by my current user data.

Despite the fact that it would take days to mount on the ibook, I was wondering if it is possible to mount a 100GB dmg on a hardrive that is only 80GB?

OS X :: Using IDVD And Dmg File?

Jul 16, 2009

I read where it is good to save an iDVD project as a .dmg file so that burning it again later will be faster. I have done that with a project. Now I want to burn more copies, and just wanted to ask how to do this. Do I open iDVD and burn it from there? Or can I use Toast? If so, what setting? Or can I just drag the .dmg file onto a mounted DVD? I will want it to play on a standard DVD player, and for PC users to have access to the photo files that are included. It works fine that way when I have just used iDVD to burn it.

OS X :: How To Merge The Disk On The Apple Support Section Under Troubleshooting Articles For Disk Utility

Oct 7, 2010

After I erase the hard disk it shows 74.5gb free, almost. It says there is 42.3mb of space being used by 2 files which I understand are used for read write or partitioning or whatever.

When I then leave disk utility and go to the actual installer, the destination disk (untitled - 74.5gb) shows only 73.9gb free space. What is taking up an additional 500mb of space on the hard drive?

Apple support told me that somehow the disk has been altered and I lost space on the disk or I am now using a seperate partition that isn't showing up. Disk utility shows only one partition with 74.5gb free space. He told me I can find information about how to 'merge' the disk on the apple support section under troubleshooting articles for disk utility. I have been unable to locate this information.

Windows On Mac :: Partition Error - Back Up Disk And Use Disk Utility To Format

Oct 9, 2010

I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.

I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "back up the disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using boot camp assistant again" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)
