Corrupted Disk Image

I have a sparse disc image that was corrupted during a hard reset. Now, when I try to open it, it says that it cannot because "disk image is corrupted". I have very important files on the disc image and really need to get it recovered. So far I have only tried repairing it in disc utility-to no avail.
Is there any other way I can recover it?
Thank you in advanced.

I hate to be the bearer of bad news, but I don't know of anyway to mount a corrupted disk image. That said, you could investigate the Unix command, which may have way to verify and mount it:
hdiutil
Launch the Terminal app in /Apps/Utilities/, type this in, and hit the return key;
man hdiutil
Hit the space bar to page through the document, when you get an alert sound, type in a q, and quit the Terminal program.

  • How to trash a corrupted disk image ? ?

    I have what I know is a corrupted disk image which I can't seem to delete by just putting it in the trash, then emptying it. When I attempt this, I just get a progress bar saying the trash is emptying, yet there is no blue on the progress bar, none at all, no matter how long I leave it up. To get rid of this bar, I even began trying some terminal commands to empty the trash, which was nerve wracking, as although I was using a trusted website to guide me, I haven't used the terminal before. In the end, I could only get rid of this progess bar by relaunching the finder.
    So, how should I get rid of this disk image? I know it is definatley a corrupted image, as I began making it using disk utility, and stupidly quit disk utility whilst it was in the middle of making it.
    Here is my info on the image:
    - It is encryped.
    - It's 60 GB in size.
    - I originally created it on an external hard drive, then moved it to my trash to try to delete it.
    Any help on how to delete it from an experienced user? I'd be most grateful. I think for now I'll try putting it inside another larger disk image on my external drive and erasing that image using disk utility. I can't erase the whole external hard drive, so that's the only option I can think of.
    I've just realised the problem maybe that I was trying to put a large 60 GB disk image in my iBook's trash, and as I only have 30 GB avaliable on my iBook's hard drive, surely that caused a problem? I can't believe I only just realised that... what an idiot I am!

    I would suggest you reboot your Powerbook G4 and then download a copy of TrashIt <http://www.macupdate.com/info.php/id/8214>. That app should allow you to remove the large disk image in your Trash.
    Also, the free space that you have on your internal hard drive shouldn't effect your Mac's ability to delete a file on a separate drive that is larger than that free space. If the disk image is corrupted, that's probably the real issue. After you get rid of the file, I would suggest running DiskWarrior on both of your drives to verify that everything is okay.

  • Reliability of restoring from a disk image vs from a "normal" backup file

    How would you rate the reliability of restoring your data from a disk image file (a sparseimage file, in this case/question) versus from a 'normal' file, e.g. one created by the Backup 3 app?
    I read a few discussions here that mention corrupted disk image files...that result in a total loss of data...as opposed to other types of backup files, in which individual files, or folders, could be corruputed.
    For some context: my ultimate goal is (a) to create reliable backup files, e.g. in folders in my Home Folder, stored on an external disk drive, and (b) to secure that data.
    Thanks to Niel, in a prior discussion, I discovered that I could create a sparseimage file on the Lacie (encrypted).
    http://discussions.apple.com/thread.jspa?threadID=763337&tstart=0
    I could then select that secured file as the target / destination for the backup file/s I'm creating with the Backup 3 app. When I log out, that file is locked tight.
    But is this 'elegant' solution for backing up data "reliable" when I'll need it at 3am on that dark day when...?
    Many thanks.

    I keep both images of my boot volume which is just OS and apps, and of my home directory. But I also have full regular backups as well. It is not "either or" but a matter of having backup sets that will work. And rotating those sets.
    A daily backup, weekly, and monthly. That could require 3 or even 7 or more. Or partitions. But definitely more than one disk drive.
    One disk drive backup set should always be safely off line when making a backup set.
    Just as I have a clone of the system, an emergency boot drive, and one backup of the last OS revision.
    You have to change sparseimage to dmg if you hope to use Apple Disk Utility Restore, especially if you are working from DVD and not from a hard drive.
    I've used DU restore and SuperDuper and never seen or suffered a problem or corruption. But I zero drives before use.

  • Corrupted files within encrypted disk images

    Greetings Apple Hivemind:
    I've run across a repeatable problem when using encrypted disk images from Disk Utility.  Essentially, I'll create an image using settings like are shown below:
    The disk image is then used for storing data.  In my case, this is usually data for Adobe Lightroom.
    At first, this worked very well, and I housed the disk images on my household NAS, connecting via samba (smb) to it on my Mac.  Over time, however, something odd started happening:  Files on those encrypted images began getting corrupted whenever I tried writing new data to them.
    My first incident was where Lightroom informed me that the catalog it was trying to open was corrupted.  I  tried to create a new one on the same encrypted volume, and it too was instantly flagged as corrupted.  I opened the individual image files on the volume with no problem, so I wasn't thinking that the volume was the culprit.  That is, until I tried dragging new image files to it manually.  The new files were immediately either completely unreadable, or a mish-mash of the content of random OTHER files on the volume!
    The result was that all old data seemed intact, but I could no longer write new data to the volumes without major data corruption issues.  I thought that this was isolated to one volume in particular, but it soon started happening on ALL of my encrypted volumes eventually.  Including those which were not, and never had been, housed on my NAS, but were on my local hard drives.
    I've since "evacuated" all my data from these images, since the ones created by Disk Utility appear to be useless, and am seeking an alternative.
    Is this something that anyone else has encountered when using encrypted disk images?  It seems like this is something I should really open a support ticket for, but I can't say I've ever tried it, so I don't know how successful it would be to do so.

    I should add that I've tried using the "Repair" and "Verify" functions of Disk Utility on the volumes, and despite the obvious issues that exist in them, the utility doesn't find (or fix) any inconsistencies.
    Are you repairing/verifying the actual disk images, or just the partition they're on?  If the partition, it won't look inside them.
    Drag one to Disk Utility's sidebar, select it, then use Verify or Repair.  Note: the usual messages may not appear on the DU window.  Click the Log icon in the toolbar or select Window > Show Log from the menubar to see them.

  • Trying to download FCPX trial.  Disk image is corrupt.

    I've tried multiple times in different browsers to download this trial.  It's always 1.69gb and when I open the disk image I get an error message (a different one each time) that the image is corrupt.  Whats going on? 

    I don't know but if you have access to another Mac (or a friend's) you could download it on that and copy it across using a memory stick, external hard drive or network connection.

  • Dock gets corrupted on Iintel machines/10.4 after restoring from disk image

    Hi all,
    I run a script at home that creates an image of my boot disk every night (it reboots into another volume, runs SuperDuper! and boots back into boot volume. I also use master disk images to deploy Macs at work. Every time an image is restored the dock becomes a mess, it looks something like this:
    http://a-world.net/files/dockmess1.jpg
    ...random icons pointing to random files, example, this is what used to be a Firefox icon, not:
    http://a-world.net/files/dockmess2.jpg
    This only happens on Intel Macs and started to happen recently after one the system updates. It wasn't happening under 10.4.6 I think but it started some time after.
    What's even weirder is that restoring com.apple.dock.plist from backup (Retrospect) doesn't seem to help, the prefs get corrupted anyway. Is there any other prefs file responsible for maintaining links betwen items in the Dock and originals? By the way desktop shortcuts do not get messed up, only the dock.
    Any ideas? This is very annoying. Thanks.

    This behavior is happening to quite a few of our computers. What they all have in common is that they are Intel Macs that have been upgraded to 10.4.10. I have verified on our test boxes that the problem does not occur with 10.4.9, then appears in 10.4.10. Don't know why.

  • Corrupt Apps/Disk Images Wrong file creator wont launch

    I have a strange problem.  Ive just upgraded to os 10.8 with a clean instal. I was in the process of reinstalling my applications. I keep them on a disk image on a external drive. The drive came unplugged by accident. when I re opened the disk image I got a message that the image could possibly damage my computer do I want to mount it. I did and copied all my installers off it.
    Now when I open any of them for example skype, I click on the dmg, the disk image mounts and I can copy the app from it. When I click on the app  to launch it I get the gatekeeper message,  it says it was created by Preview. [see screencap] and when I click open nothing happes.
    I can download a new copy of skype and it works. I have limited bandwith with my isp so Id like to avoid redownloading all my installers if possible. Any ideas ?

    Thanks.  It starts to launch, gets to the point where you can see the doasboard then errors out. 

  • Disk Utility doesn't finish creating new disk image - naming issue??

    Recently I upgraded to Snow Leopard and carried along an empty disk image created in OS 10.4.11. I use these for archiving data on read-only DVDs and password protect the images.
    In the earlier OS, I found the practical limit for the dmg was 4.3 GB, containing 4.27+ GB of data (anything larger failed when attempting to burn data DVDs). Today, when I looked at my empty dmg file, the OS 10.6.6 Finder showed it to be larger both inside and outside (just under 4.7 GB inside I think - didn't write it down). I suspected that it may be corrupted or at least not give correct directory information, so I deleted this dmg as a precaution and tried to make a new one with the old size by selecting custom size within Disk Utility. Now every time I try to create a new dmg this it stalls at about 100 MB.
    The image format panel has several additional settings in OS 10.6 . There are two places for names - in the "Save as" field above and in the "Name" field below. (Haven't yet found any documentation where the reason for this is explained or which lists possible name limitations. The Help info appears to be identical to what was in 10.4) I've tried making both names the same, but it still stalls
    Disk Utility settings:
    Save as __Diskname
    Name in lower field __Diskname (have also left it blank no difference)
    Custom 4.3 GB
    Mac OS Extended (journaled)
    128 bit encryption
    single partition
    read/write format* (also tried CD/DVD master - no difference)
    * All files are not necessarily added at once so I'm pretty sure I want this to be read/write
    Message was edited by: James Kilgore
    In case this isn't obvious I mean read/write formatting on the hard drive, but when burned the format will remain the same whether or not the disk used is rewritable

    Hi Michael,
    Did you reformat it HFS+ or something else?
    Some USB2 Flash Drives Write at a disappointing USB1 speed, but Read at USB2 speeds.
    From what I can find, that isn't one of them and should take maybe an hour & a half to transfer 30 GB to it. Of course if write speed IS USB1, then you could expect 2 days or more.
    I'd stop it. Reformat it, then make the Image on the HD and try transferring it.

  • Trying to create a password protected disk image in 10.8.4

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and  Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Disk images not mounting

    Here's the question: how come .dmg files downloaded from apple.com (amongst other places) won't mount?
    Here's the detail: This has to be a FAQ going by Google searches. I've downloaded the Mac Firefox DMG 3 times, and the Safari DMG from apple.com once, and when I try to mount the images I get a range of different cryptic errors, including "codec overrun", "not recognized", "error -some number or other", and so on. Sometimes, I get two different errors for the Safari image.
    Existing disk images on my hard drive mount fine. Today my hard disk has been playing up, with files being corrupted, keychain being broken, prefs disappearing, and so on. I boot from the Tiger DVD, run Disk Utility and Repair Disk, tells me no repairs carried out as all hunky dory. Use Disk Utility on the HD to check permissions, those are fine. Run Onyx maintenance, all is fine. I've not changed the router prefs at all, so it's not that corrupting the downloads.
    All was fine until mid-afternoon today, when a number of apps (Firefox, Safari, Dreamweaver) started behaving strangely and the machine kept on hanging. On restart a number of taskbar icons became question marks, so something's being corrupted. Some downloaded PDFs became corrupted.
    What I might try to do is download DMGs from my work PC, put them on a stick, and try to mount them. If the problem recurs then that would eliminate download errors.
    My conclusion is that either the OS has become damaged, or the HD is physically fubar'd, or at least has some physical errors on it somewhere which DU isn't picking up. If the latter I'm screwed as I'm out of warranty and I might as well chuck the machine in the bin, so let's hope it's the OS. I could reinstall the OS (again) but a) that would be highly time-consuming as I'd also have to reinstall a shedload of apps, prefs, configs, etc, and b) if there's a physical HD error it'll do zero.
    I've already spent some fruitless and frustrating hours today on diagnosis, and having done tech supp in my career I know what to look for, so this is my last throw of the dice to try to get some kind person to suggest a) a diagnosis, and b) suggestions for a cure.
    Without a cure I might as well take a clawhammer to the thing and get a Linux laptop. Ok, PCs are far inferior to Macs with crappy hardware, but at least you don't lose over a thousand quid when your PC laptop fails.

    I was able to get a partial fix of this problem by following instructions that I found on the All Experts web site:
    Regarding disk images and mounting media:
    delete the following files and folders:
    * /System/Library/Extensions.kextcache (file)
    * /System/Library/Extensions.mkext (file)
    * /System/Library/Caches/com.apple.kernelcaches (folder)
    (Note that after deleting these files you need to reboot your Mac for the fix to take effect.)
    All of these files and folders were date 18 Aug 2009, which is in around the timeframe when I installed the last security update for OS10.4 ppc.
    I say the solution is a partial fix, because it did allow me to open some, but not all .dmg files (the problematic ones are showing a checksum error). Now I find that iTunes will not operate (yeah I know that should be another thread), but I have not used it in several weeks, prior to the last OS update.

  • How do I convert TC sparse bundle to disk image?

    Ok, this question could be cross-listed under a number of threads, so I had to just pick one...
    A few months ago, the HD in my MB was clearly dying, so I replaced it with a larger, faster drive. All good, until I realized I had been close to maxing out my Time Capsule before I upgraded my MB's HD, so I upsized that, too.
    Fast forward 2 months.
    I have a weird problem where iPhoto events start going dark. The database had these previously imported files listed, but the files themselves were nowhere to be found! The event in iPhoto showed black squares where the images used to be, but even looking in finder... No pics!
    I want to go back into my old (saved) HD that I pulled from my Time Capsule. I stuck it in an external USB enclosure, and hooked it up. I told Time Machine to use it as the backup, but after it 'verified' it, it didn't show me the archived files. It does show a 'sparse bundle' in finder, which I understand is similar to a disk image. So is there a way to convert the sparse bundle to a disk image? Do I need to plug my old TC HD back into the TC to get to that archive?
    Help! Among the lost photos are ones from a trip to Australia and my grandmother's memorial service. I need to get these back!
    Thank you in advance.

    I've already done the TC surgery once before and the hardest thing was loosening the adhesive on the rubber pad / gasket on the bottom of the unit. After that, I completed the HD replacement in about 15 minutes... piece of cake. There's actually a good tutorial on AppleFritter. But I digress...
    It's not too much of a digression. Remember that if you are just firing up the Time Capsule with the old hard drive, you don't have to reassemble it. Just swap out the plugs from the old drive to the new and turn it on. A true PC geek never runs with the cover on.
    However, messing around with adhesives and thermal paste introduces a new element of risk. If you know the dates that have good data, and you are comfortable merging the newer photos back in, accessing the data via the Finder on an external enclosure would be faster and safer.
    So, can I turn the TM backups off and still enter 'TM' to browse through the backups on the drive? I've ID'd the specific dates of my missing photo events, so as long as I can get into the backup, I will know just what folders to search for in the 'Originals' folders in the backup.
    Yes. That is probably one of the most important and least known tips about Time Machine. You can still use it even if the backups are turned off. Furthermore, if you ever start to have problems on your machine, you should turn off Time Machine to avoid further corruption of your backups.

  • What's the best way to create disk images?

    of 300GB  hard drives or partitions?
    Disk utility is failing for me with an input/output error.
    A typical example:
    I have a new HFS+ 500GB external FW 800 drive that I am using a destination.
    I will boot from my original 'install' DVD and then open up disk utility to start the disk image creation.
    Note: my source is my "Macintosh HD" partition that is around 300GB.
    Everything looks like it is running well, then a couple hours into it, it fails... something like:
    "cannot create img.. blah input/output error".
    Note: Verify Disk shows no errors on the source.
    One guess is that the img creation process is failing after I leave the computer and perhaps my computer falls asleep. I tried setting the 'Energy Saver' prefs in the systems prefs, but of course, since I'm running off the install DVD, I wasn't able to get into the prefs.
    Anyway, ultimately, I need to create periodic disk images of my macs.. so what are people using to do this?
    Thanks for the comments!
    Donovan

    Eric, Carbon Copy Cloner is what I was leaning towards. The owner says his guess is that there are bad blocks on my HD, and since Disk Utility is block based, that it is failing where CCC is file based, and will just skip files that are corrupted or that it can't copy.
    I guess I'll roll with that for now.. but it would be nice if the Disk Utility logs spit out a more descriptive log.. instead of "could not create disk image, input/output error".
    Thanks!

  • Disk Utility Error 61 when attempting to create disk image on external driv

    I would like to make occasional archive backups of my three macintosh computers. I bought a new Western Digital 2TB drive for this purpose, and formatted it as Mac OS Extended. Trying to do a disk image backup using Disk Utility, I follow the directions:
    - Startup from an install DVD.
    - Start Disk Utilities and select "Restore"
    - Drag "Macintosh HD" into the Source box
    - Click on "New Image" and select compressed and 128-bit AES encryption
    This leads to the error message: Unable to create "....." (error -61)
    I have enocountered this problem both with my iMac G5 and a MacBook, both running Leopard.
    Does anyone know what this error means, what I am doing wrong, and/or if there is another way to create disk image backups? Help!

    1. For reasons I don't know disc images seem to become more fragile the larger they get. They also can be subject to file corruption that affects the entire disc image, whereas file corruption on a clone would only affect certain files.
    2. You cannot put multiple clones on the same volume. Each clone must be on a separate volume, but you can have multiple volumes on a single drive simply by partitioning the drive accordingly. Of course you need a drive large enough to accommodate each clone. Each clone should be to a space equal to the capacity of the cloned drive.
    3. I'm not a big fan of TM, although I must confess it has become more reliable since it's release, especially with Snow Leopard. However, there are many backup utilities that can create clones, perform incremental updates, and archive changed files. See the following:
