OS X :: ISO 9660 Restore Functionality In Disk Utility Broken In 10.6.5 - Error 254
Nov 17, 2010
Steps to reproduceOpen Disk Utility Drag an ISO image into the left sidebar Insert an USB Stick with enough space to contain the image Go to any restore tab in Disk Utility Drag the ISO file to the source Drag the Volume from the USB drive to the destination Check erase destination Hit restore
Results for me are (in any number of varieties to do this) either "Invalid argument" or in the log "Could not validate source - error 254".

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)

I'm running OSX 10.4.11 on a 12" PowerBook 1.5 GHz with 1.25 GB of RAM and an 80 GB HD.
When I run the disk Utility to Verify Disk, it ends with the message, "Error: The underlying task reported failure on exit." This happens if I run the Disk Utility from the hard drive, from the OSX installation disk or from an external hard drive.
The Repair Drive button is always grayed out no matter where I am running the disk Utility from, too.
So far, I haven't had any other unusual things with the operation, but I'm concerned that this could be an early warning of problems to come.
Has anyone else had this problem or have a clue?
I have cloned the entire hard drive onto an external drive with Carbon Copy Cloner. I know PPC systems won't boot from a USB drive, but I was considering booting from the install disk, re-formatting the drive from there and then re-installing from the external by running CCC from there. I hope someone will have a direct solution to repairing the drive without doing all of that.

I just got my computer yesterday and when running the "repair disk" function, I already get an error! Since I used migration assistant to move everything off my old mac to my new mac, I'm not interested in reinstalling the whole OS and transffering all my files again. This is a new computer, and shouldn't have this problem this early. I also get the same result when starting up in the recovery partition. How do I resolve this?

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??!!

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?

On my new MBP, I had Tiger and Boot Camp 1.4 Beta.
When I got my Leopard UTD disc, I simply did an upgrade. Last night, I was fed up with some of the weirdness, and decided to start with a clean slate.
I removed my windows/boot camp partition, popped in my Leopard disc, selected erase and Install, and within 30 minutes it was done (seems way too fast...wtf?)
Anyway, I go through the Boot Camp steps to install Windows. When I get to the Windows setup where you select a drive to install, it doesn't give me the option to format the Boot Camp C: drive, but instead just installs.
After rebooting, it gives me a DISK ERROR.
A bit of googling shows others have had this problem, too. Is EVERYONE having this problem? Did Apple break Boot Camp with Leopard?
Is there any viable workout other than formatting to Tiger, installing 1.4, then upgrading again?
Is it possible to uninstall the Boot Camp assistant on Leopard and find/download/install Boot Camp 1.4 on Leopard, and go from there?
I need windows for school - and this is driving me nuts!

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.

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.

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:
EFI
Macintosh HD
Recovery HD
06
[code]....

MacBook Air, Mac OS X (10.7.3)

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?

I just used Disk Utility to make a backup of a MBA (65GB) onto a 500GB external drive (Restore from internal HDD to external HDD). I then reformatted the internal hard disk and proceeded to restore my backup (external HDD to internal HDD). I soon received an error message stating "Restore Failure - not enough space". I guess that means Disk Utility backups are a one-way operation, since you can't restore from a larger drive to a smaller one? Is there something I am overlooking? I ended up using Carbon Copy Cloner to do the job, but I'm wondering how (if?) restoring from a larger backup drive is possible using Disk Utility?

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.

"Disk Utility has lost its connection with Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility".
I keep getting this error when trying to erase an external hard drive with Disk Utility. When I restart, the error appears again. I've seen others with this problem but haven't found a solution. I've tried removing iTunes from Applications and deleting select iTunes receipts.
I'm running OS 10.4.11

I clicked "Verify Disk" and i got that, the other two options worked. I read up on this on Apple's site but I am not having any other issues than the notice. I was told to run Disk Utility ever so often to keep my mac fast. I just happened to do it today and I got that. I am trying to avoid having to do ANY sort of reformat.. I don't have any means of backup. Like I said I am not having any other problems. I am able to restart and log in without any problems. Should I be worried about this since there is no other issues besides the notice itself?

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.

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.

Mac OS X (10.7.3)

I installed Ubuntu on my iMac, and it made 2 new partitions: DISK0S3 and Linux Swap. Here's what my disk utlity looks like: When I try to remove Linux Swap, it says that the partition (map is too small. When I try to remove DISK0S3, nothing happens and it keeps running forever before I press +Q to quit.

I have spent all day with a colleague wrestling with a 4 and 1/2 year old G5 tower that has been throwing up all sorts of cranky errors. (i.e. firefox crashes, flash crashes, programs wont load, itunes stops working, firewire drives make it insane). As part of the diagnostic flow, I attempted to verify permissions on the core HD. Disk utility only took a couple seconds to determine that there is some unknown error with the HD, and it cant continue. This leads me to believe that we are dealing with a flailing drive, which very well MAY be the root of the problems! Time to make an external clone onto a fresh HD, and see if that helps.
Install CCC 3. Open CCC 3, it hiccups on the dock, and then nothing. *roll eyes*. Install super duper. Run super duper. Now super duper refuses to let me make a bootable clone of the core HD? Fine, if that is how you want to play this game. I get two SATA enclosures. Put the suspect drive in one, and then a fresh drive in the other. Plug both into my MBP where i run a CCC bootable clone. Couple hours later, it is complete. Plug the new clone into the G5 tower, and it does not see it as a bootable drive. Okay, lets try the CCC clone again. Same result. I am desperate for options.

I am desperately trying to burn a ISO file to a USB and external HD but Disk Utility does not want to. Instead I get the error message "Could not validate source - error 254". So there must be a problem with the source which is the ISO file.
I already tried setting the Partition Map Scheme to both Master Boot Record and GUID Partition Table. I also formatted the drive to FAT and HFS+. I cannot find the cause of this error. It clearly looks like Disk Utility does not like burning ISOs to USBs or HDs.
However, I really really need to this since I cannot burn ISOs with my SuperDrive which is also a common problem [URL]with my MacBook Pro.

I just restore my Mac OS to a single partition and then I tried re-partitioning but it's giving me an error.
I've tried several times, tried using different sizes every time. My HD's capacity is 250GB, and I've got 108.95GB free. So I am sure that making a new partition of 35 - 40 GB is not a big deal. I also tried using Disk Utility, both from the Mac OS install disc and while using the Mac OS itself, but it keeps giving me this error. I do not want to format my Macintosh HD's partition because I don't have an external HDD on me at the moment so I will not be able to back up. I have a lot of important data that can not be deleted.

I am trying to format a SDHC card on my MBP. I am trying to create a recovery SDHC disk for my MBP.
The disk is a Transcend 16gb (class 10).
I formatted to Mac OS Extended (Journaled) w/ a GUID Partition Table but after this, Disk Utility is now showing only 10.38 gb of usable space, but finder is showing me the full amount (15.79 gb). When I look in finder there are NO files or folders on the drive.
I tested trying to put more than 10.38 gb worth of files on the disk and was told there was not enough space. If I format the disk to anything other than Journaled, I get the full 15.79 gb. Has anyone ever experienced this before?

I bought a 1TB Iomega Prestige drive, it worked great for a few months. Started making loud clicking sounds. Iomega sent me a replacement drive (refurbished).
I am using it as my time machine backup in Leopard, so it was really just a matter of plugging it in, formating it with the OSX file system and setting it up for time machine.
When attempting to format from Disk Utility, I get an error (see screenshot).
(Additional info: I can access it and format it without any problems from Windows 7 based PC).

After upgrading to 10.5.7, numerous permission errors highlight regularly in Disc Utility, which I run weekly (probably for too often). I never saw these with 10.5.6, or for that matter any earlier incarnation of the OS. I have also noticed progammes hanging more than before (especially Mail). I have run DiskWarrior and that didn't report anything untoward. Should I give up worrying about this and maybe join the Foreign Legion instead?

I have a G4 powerbook from around 2004 that was running slow so I tried updating the mac software since I hadnt done it in a while after downloading and installing the suggested items my computer has gone a lil crazy. First off i noticed my dock is completely missing and I've tried numerous things to fix it that were suggested to me but nothing has worked.
Next I attempted to do some restoring using disk utility that had also been suggested and it turns out disk utility wont even run I get the error message "You cannot open the aplication "disk utility" because it may be damaged or imcomplete". This message also appears when i attempt to open safari or itunes.
I am no longer able to find my restore discs so I dont have that option at the moment, any help would be greatly appreciated, I am about to go back to school to pursue another degree and not having to buy a new comp would be great news.
here are the items that were installed with the update:
2009-10-25 17:23:21 -0600: Installed "Java for Mac OS X 10.4, Release 7" (1.0)
2009-10-25 17:23:47 -0600: Installed "Migration and DVD/CD Sharing Update" (1.1)
