Error 49168 when attempting to create Disk Image

After attempting to create a disk image of a specific CD, I have been unable to create a disk image from any folder or volume. Every time I try, I get (toward the end of the dmg creation prcess) "Unable to create (...) - error 49168."
Creating a blank disc image still works fine.
Judging from my attempts to find answers, this seems to be a rare problem.

I just got the same error and have been looking around Google and elsewhere online. It seems to be rare but I haven't yet found a very good fix, the only thing I've found is this: http://tinyurl.com/d52l4 I'm currently trying that and I'll report back to let you know if it works
All I did from the link was copy the contents of the folder I was trying to burn into a new folder and everything worked just fine. I suppose it had something to do with the permissions of the previous folder. Anyway, hope that helps.

  • 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:

  • JBO-26031 Error encountered when attempting to create new row

    Hi
    We are experiencing an intermittent error whereby sometimes the call to
    View1Impl.createRow() fails with the following error message:
    JBO-26031 Association end Entity1 of assoc Entity1Entity2FkAssoc invalid for entity based Entity1 in view object View2.
    View1 is a generated view object based on a single entity whereas View2 joins the entity from View1 (Entity1 in the error message) with Entity2 and three other entities.
    View2 has previously been executed with a WHERE clause defined within the code. We have tried re-setting the parameters to null prior to the createRow() call but this does not seem to have fixed the problem.
    Has anybody any suggestions as to why this error would be thrown (and if possible why it does not happen every time we attempt to create a new row)?
    Thanks in advance for any help

    I have exactly the same problem when I deployed the ADF application to JBOSS.
    I am using jdev 10.1.3.3 ADF 10.1.3.41.57 and JBOSS 4.0.3 sp1 / JAVA 1.5.0
    The strange think is that when I am running the application from jdev (using the embedded OC4J) the problem dos not occur.
    Any suggestions?

  • Cannot create disk image in Disk Utility

    I am trying to create a disk image of my macbook pro hard drive to an external firewire drive. The image starts, then I get an error that says "unable to create disk image: Input/Output Error"
    I've verified both disks and permissions, but the image creation still fails. I've never had this happen before, and can't find anything about it. Any ideas?
    Thanks,
    -Jason

    You're a genius - THANK YOU!!!!
    I just wanted to backup my HD before I upgraded to tiger again .. had my main HD go flakey on me and had to resort to my back up jaguar drive - You're a genius and this worked for me .. as I got the device busy message as well. I figured it was because I was on my start up drive, but didn't have the extra OS drive anymore to switch start up disks to do this.
    Thanx so much for your answer!!!
    Try this. Open disk utility and highlight your
    MacintoshHD(the one you want to copy). In the
    options inside the
    window(FirstAid-Erase-RAID-Restore) choose restore.
    For the source--The Top field--Drag the highlighted
    MacintoshHD to the source field.
    Destination Field--Drag the image of your lacie
    drive(Thats also in the side bar below your
    MacintoshHD) to the destination field. click
    restore....

  • Disk Utility - Input/Output error when creating disk image

    Hello!
    A few days ago I was unable to turn on my Macbook Pro, and was stuck on the white screen. I've been searching around quite a lot on this forum, and before I try fixing anything, I REALLY need to back-up my files! I just bought a 2TB hard-drive, which I have partitioned to GUID and Mac OS Extended (Journaled), (it perfectly works on another Mac).
    I now want to attempt to create an image of my harddrive (Macintosh HD) onto my external drive (which is empty). I've tried doing this both in 'read-only' and in 'compressed', but about halfway through, I receive a message saying "Unable to create 04/2014 backup.dmg (Input/Output) error".
    I saw on another similar post that I might want to install DiskDrill or DataRescue. I'm fairly sure this is impossible for me to do, since my screen is completely white, and I'm unable to access my desktop.
    I can only access Disk Utility through pressing command+R when starting my computer. Hence, I need to successfully back up my files through Disk Utility...
    I'm aware that my HD may be corrupted since this is happening, but there must be a way for me to put an image on my external HD?? A few days ago, when I clicked on Repair Disk it said "Impossible to repair: invalid node structure". But now, it says that "Macintosh HD appears to be OK". I have no idea what's changed... And I can still not start my computer past the white screen...
    I'm very bad with IT and computers, and have extensively tried to fix this on my own, but I'm now stuck here, with this "input/output error"...!
    Any suggestions would be greatly appreciated! Thank you!
    PS: I do not have Applecare, this is an old computer from 2009.

    Thanks for your answer.
    Yes, I thought that might be the case - but I'd taken my Mac and Logic disks to a Genius bar, and the 'Genius' had said he'd fixed the issue. I just wish he'd explained what he did and why he didn't replace the faulty disk(s)!
    But is there any way around having the claim a disk, now I'm living abroad and my 'warrantee' has run out? It's going to be a pain in the fundament trying to claim a replacement set.

    The Mac SuperDrive built into your Mac is the Optical drive.
    1. Insert your Windows DVD in Optical drive. Disconnect any external storage.
    2. Insert a USB2 Flash drive. This will be used to hold the BC drivers.
    3. Start BCA. Check the options to download software and Install Windows. You do not need to download Windows. The BCA will download the BC drivers to the USB.
    4. Partition your drive.

  • Cannot create disk image iDvd 7.1.2 (multiplex error)

    I'm at my wits end and extremely disappointed.
    Basically, I've gone through the threads that I can find, I'm down to importing a basic movie directly into iDvd.  No menus.  No options enabled (that I'm aware of). 
    When I go through the iDvd process of creating a disk image all goes smoothy until the very end when I get a multiplexor error (no error code or text saying why). 
    Extremely frustrating.  This is on a new Macbook Pro running 10.7.2.  I don't have problems with my other Apple systems, just this new one.  Perhaps Apple would like to take it back??

    Hi
    Multiplexing Error
    Multiplexing error is a very complex problem due to many things (long long list following) -
    one common but not obvious reason is that material on the iDVD menu goes outside the TV-Safe area (or just touching it).
    So first - turn on TV-Safe area and move any object well inside of this.
    Wide screen stretched - usually (as I think) it is due to making a 4x3 movie in a 16x9 wide-screen project OR the other way around. This forces one to on flat-screen TV (or other) set the presenting view right - My has 4x3, wide-screen, zoom and auto-wide-screen and I have to switch this by my remote for some DVD I've made "wrong" way.
    Now my long long list on Multiplex Error
    LONG LONG LONG LIST
    Multiplexing Error
    PART One.
    Use of strange video/audio material e.g. .avi, .wmv, .mp3 etc.
    I only use.
    Video - StreamingDV (miniDV tape via FireWire) and
    Audio - .aiff (as on audio-CDs) (else converted to this .aiff 48KHz)
    Photo - .jpg (.bmp known problematic)
    Chapters !
    A.    Using strange letters in video project name e.g. +,/; etc. keep to a-z and 0-9 strange letters in project name e.g. +
    as described by Donnyboy69.  Does the title of your project have any symbols or decimal points in it. If so, that is why you are getting the error. I had a project that had a + sign which caused the same problem. I renamed it without the symbol and low and behold, it worked.
    B.    Location of Chapters
    • Can’t be at start or end of movie (Skip first/start one - iDVD sets this by it self. At the End - no need)
    • Not in a transition (or within 2-3 seconds from it)
    Important when from iMovie HD6 or previous - Now also observed when using FCE 4
    PART Two.

    Once I did that, I was back in business.

    Do a safe reboot (by holding down the shift key until you see the spinning gear on gray background, then release, then restart when your start-up screen appears).
    I always makes a DiskImage first and test this so that it runs OK
    I use only - Verbatim DVDs
    I use only - DVD-R
    I burn at an as slow speed possibly e.g. x1
    This gives good DVDs

    Multiplex Error
    Chuck, Chicago 2/7/2009.
    Back again. Here is what I have found to work. I also have and use a LaCie DVD-R/RW DL external drive and a LaCie external hard drive as well. Since yesterday I have tried a few ways to burn a themed iDVD project having four 56 minute movies on it, amounting to 226 minutes onto a DVD DL disc, capacity 240 minutes. Apple tech support really didn't know what to do but gave me a very good tip. I had two options left. Apple tech support's tip was to try disc image. One of the replies on a thread with this subject said not to, but my experience today is good. Put your project onto "Burn to disc image," under "iDVD, file." Yesterday encoding took me 23 1/2 hours. Overnight for iDVD disc image, encoding took 21 1/2 hours (again) while I slept. This morning I tried to copy/burn disc image to a DVD with Roxio Toast 7, and it stopped near the end of the burn with some kind of "error" message. So then I tried Utilities> Disc Utility> Burn icon, and followed it through. Be sure to click the DVD DL drive in the window "Burn disc in.". I had one other problem though. At the end of a 46 minute copy, it started to verify, and at the end of verify it rejected the burn. So I tried again, and when "verify" appeared, I clicked on "Skip." The disc finished burning and is doing fine and well. A long and tortuous process, but at last something works. I made several additional copies using Disc Utility. Best wishes. Chuck, Chicago.
    2. Disconnect any other external devices not absolutely needed.
    e.g. external USB/USB2 hard disks, other FW hard disks etc.

    (Not a 'guy' but I will answer!)
    First, I do not think that mixing wide-screen and standard makes a difference in iDVD.
    Second, you should use a better brand of DVD disk. Also, many of us have experienced fewer problems on playback with DVD-R disks. Recommended brands here are Verbatim, Maxell and Taiyo Yuden. Memorex and TDK are not consistent and may not give you a correct burn. They apparently have fewer layers in the composition of the disk. I have always used Verbatim DVD-R disks and have not had any burn problems.
    Also, choose a slower burn speed, 4x or less.
    Third, to determine if the iDVD project will burn properly, create a disk image file (from within iDVD, go File->Save as Disk Image) and test it. Mount the disk image and then open DVD Player (in Applications) and view your project. If it plays correctly, you can then burn the actual DVD disk from the disk image file using Disk Utility.

    I did everything I've seen suggested, but a friend (who used to be an Apple Genius) suggested that I do a safe reboot (by holding down the shift key until you see the spinning gear on gray background, then release, then restart when your start-up screen appears).
    It worked, and I got a clean burn from iDVD.
    Hopefully this can help other people.

    Well, I finally got it, and it was odd enough to post here incase anyone looks this topic up again. Many things were tried, including burning the unedited film, the edited film without titles and chapter markers, abbreviating the chapter markers in case length was the issue (remember the old iMovie used to truncate them when moving to iDVD?). In the process, I noticed that one, and only one, chapter marker was on the same line as the title marker. All the others were on the line above. The only way I seemed able to change that was to clip a few seconds of film. After that last clip, the offending marker took a place on the line above, as were all the others. That run published, compiled completely and burned. That's one for the books.
    One user more writes
    To add my experience with Multiplex Errors using iDVD (7.0.4), I recently created two iDVD projects
    Video from both passed from FCE 4.01 with chapters
    One project worked fine in creating disk image file
    The other gave Multiplex Errors
    I tried suggestions to remove special characters and no chapter marks at beginning, but nothing worked
    Note that I've used iDVD for dozens of projects and this is first time I've run into Multiplex Errors
    Anyway, for problem project, I tried an experiment where I removed all chapters in FCE and passed to new iDVD project
    This time multiplex errors gone
    So had something to do with chapters
    So now I tried numerous experiments to remove individual chapters and try again creating disk image with new iDVD project
    After numerous tries, I was able to narrow problem down to 1 "Bad" chapter mark
    That is, when I left the "bad" chapter in my FCE project and passed to iDVD, iDVD gave multiplex error
    When I removed "bad" chapter mark (and others in), no multiplex error
    As a final experiment, I moved "bad" chapter mark about 5-10 sec's beyond original point and passed to iDVD, the multiplex errors now magically went away and I was able to finally create my disk image.
    I have no idea why this worked, but thought I'd mention here in case someone else runs into similar problem.

    In addition to Bengt's fine advice, burning errors can occur if you have located any of your menu buttons wholly or partly outside of the safe TV viewing area. Go to your main project menu, then click on View/Show TV Safe Area, to check. Drag into the safe viewing area any buttons that are outside the safe viewing area.
    Russ One - suggest this
    Multiplex Error-There was an error during muxing preparation
    One thing that worked for me was to export the video w/o chapter markers as a self contained movie (thereby not loosing the edits & etc). Then make a new FCE project and import that movie into a new sequence and add the chapter markers. I've used "-", "&" and "," with no problem in the chapter names. Removing the markers or exporting without them did solve the problem but renaming them with just numbers 1,2,3....5, did not solve the problem and since this problem seems to happen with with iMovie as well, it would suggest the problem is in the video or audio and in combination with the chapter markers iDVD just can't handle it. The only other possibility is that both iMovie and FCE share the same or similar chapter marker code that some how is corrupting the markers.
    Summary - What to try
    1. Chapters
    • Only A to Z and 0 to 9 in chapter title
    • No Chapter mark at very beginning of movie
    • No Chapter mark in or within 2 seconds from any transition in movie
    2. TV-safe area for buttons (no one outside this)
    3. Safe re-boot
    4. No other external devices connected - that are not needed
    SDMacuser adds to this
    • On #4 ... No ext. devices. Some think this applies mainly to ext. FW. Not the case. Also applies to ext. USB2 as well (not to mention flash drives too).
    Do not leave 3rd party devices / camera / camcorder plugged in unless it is being used with iDvd's One Step process. Certain web cams can trigger this also (especially ones with added features like LED light/s that draw additional power from the FW or USB bus).
    5. Minimum of 25Gb free space on Start-up hard disk
    6. Make a DiskImage first - reduces where problem originates
    7. Trash iDVD pref. file
    8. Make a new iDVD project
    9. Movies in project with same aspect ratio e.g. 4x3 or 16x9
    10. No other programs/applications running during iDVD process. e.g. Internet, screen & energy savers

    I am getting the above error when attempting to create an MPEG-2 file from an FCP Timeline; what might cause this problem and how can I fix?

    I'm real sorry. I am just lost. So if it does allow me to access via USB, what am I doing wrong? Why am I getting this error? I tried to go in and just import the video first and I could see the files, however they were gray, so it was not an option. Then I tried dragging them from the desktop icon and received the error. What else can I try to get my video loaded in imovie? I'm still fairly new to the mac. I have had mine for a year, but am still learning and would consider myself very green still. I have always done pretty well with a PC, so I catch on pretty quickly, but I definitely need some guidance here.

  • Another "An error occurred when attempting to change modules" error

    Hello all:
    After using Adobe Photoshop Lightroom on Mac OSX trouble free for the past 6 months, I opened up Lightroom today and received the following error: "An error occurred when attempting to change modules." I had not made any changes in between when it worked normally and when the error started to occur. I beleive the last thing I did before this error occurred was to go into the Print Module.
    Other information--I keep all my RAW .NEF files on an external Firewire (800) 750 GB drive. This is on Mac OS X 10.5 running Adobe Photoshop Lightroom 1.3 and also with 1.4.1. I'm running an iMac 20" with dual-core 2.2 Ghz Intel processors and 4 GB of RAM. I have around 25k images total.
    When I noticed this problem, I was on Lightroom 1.3. I immediately upgraded to 1.4.1, which did not solve the problem. I have also tried many suggestions in the forums including uninstalling the application and removing the .plist file.
    I thought I had come up with a solution by creating a new catalog, then importing the former into it. While this seems to work immediately after the import process, as soon as I close it, the problem manifests itself again.
    More details that may or (likely) may not help:
    - Going to the Develop and Print Modules gives me no problems. However, when I click on Library, Slideshow, or Web, I see the error.
    - I upgraded my Mac to the latest patch level after observing this error to no avail.
    So it looks like my choices are to create a new file and reimport every single time, or lose all of the work I've done for the past 6 months on thousands of images.
    Can anyone please help???? I promise to post the solution when we fix this darn thing so others may benefit. I'd be happy to run through any troubleshooting that y'all would suggest outside of switching to a Canon.
    Thanks!!!!
    Matt

    I'd first check for the existence of a file ending in .lock, which should be present when LR is in use, but if it exists when LR is quit, it can cause problems, and should be deleted.

    Just because you are the only user on the computer doesn't mean you are the administrator.
    Also, the fact that you are being asked to re-enter your serial number each time you start means that it is not being remembered because something is either preventing it from being written to you disk or (less likely) something is erasing it. This does suggest that you lack certain permissions to make changes to your computer. Not only to save your serial number, but to have access to the Lightroom files needed to change modules (they are just plug-ins within Lightroom).
    Try creating a new user account and run Lightroom from there (making sure that it is part of the Administrator group).

  • Adobe AIR - Created disk image doesn't open

    Hi, I'm trying to create a dmg file and the resulting image file won't open. I'm working on a Mac and it's not the first time that i'm doing this.
    The error message I get when I open the disk image is "Following disk image could not be opened " and the reason "not recognized".
    It's really weird, because it used to work and now for some reason stopped. First I thought it could be, because I compiled against the new SDK 4.0, but then I tested it with older SDKs like 3.5, 3.8 and 3.9 and the problem persists. Older projects which also worked fine are no more building disk images.
    My system was 10.8 and I thought the problem could go away if I install the new Mavericks, but after upgrading the problem is still there.
    Repairing disk and file permissions didn't also help.
    Has anyone some idea what it could be? I'm really at the end of my knowledge.
    Thank you very much,
    Solano

    Ok people, finally found the problem. I'm using FDT and for some reason FDT stopped to append the flag -target native when compiling a native installer. I think that some FDT update introduced this bug.

  • NEED HELP : Encountered error -47 on attempt to create QuickTime

    Hi all,
    I hope someone can help me. I'm using Shake 4.1 and making setting to use Qmaster 3.5. All seem to work fine and my images are rendered... But at the end of the process the file could not be completed... I try many output file ( tif, tga, quicktime, avi and so on... I got both error on my Macbook pro and Mac pro.
    I made a clean uninstall of Qmaster and Shake... and reinstall them after with last updates. So there is a sample messages of one of my process below. Any kind of help will be appreciate! Thank you!
    Status: Processing: frame number: 22, rendered in 65.20s. frame number: 22, rendered in 65.20s. 2010-08-06 00:21:36.139 shake[1622:60f] No file moved to the trash.

    We use shake with QMaster 3.5 all day long... it does work, but it is a bit twitchy and cryptic to troubleshoot.
    We find the elusive "will render each frame but crap out on assembly" error to be one of the compression pass on the way out. We find it works when Shake files are set to render as "uncompressed" Quicktime files.
    We typically compress it after shake output, with Shake or compressor, or Quicktime itself. Most efficient workflow is to setup a second, serialized QMaster job to compress the first Shake job's output.
