Disk images will not mount

Error message keeps popping up saying something like "disk image not configured" or something, even from sites like mozilla.
I recently took the HD out of my old iBook G4 and put it into a Powerbook, because the battery wouldn't charge on the iBook and the Powerbook had a corrupted HD.
I had also cleaned out a lot of adobe folders the other day sitting around in my library because I didn't think I needed them, and so that might have to do with why disk images aren't mounting on my computer.
So are there any files that I might have deleted on accident that prevents disk images from mounting on my computer?
I'm positive I've got the disk image mounter utility because it comes up in the monitor, but I really need some help with this one.

Hi datz;
In addition to Neville's suggestion, I would suggest that you repair your disk while booted from the install media for your Mac.
The reason I am suggesting this is that when you run disk space low as you have you greatly increase the chances for file corruption. If you don't repair this file corruption it can lead to all kinds of strange problems in the future.

Disk Images will not mount and Disk Utility will not runru

I am having some major problems with Disk Utility, Disk Images, and software update. First, Disk utility will not open or run. When I double-click the application icon, nothing happens, no message, nothing. I am running OSX 10.4.11. I have deleted diskutility prefs. I am able to run Disk Utility from the Startup DVD of Tiger. On first run, it verified and repaired permissions. I run verify and repair permissions several more times from Startup DVD and everything is fine. But Disk Utility on my startup HD will not work. Similary, NONE of my disk images will mount. No matter what Disk Image i try to mount, nothing will. And I cannot use Disk utility to mount them! So, no matter what I download, no images will mount. And thirdly, when I try to run software update, it will not work. I do get a message: it says, "Could not load Software Update." Finally, i tried to download Onyx to delete log files, etc.. but again, the disk image will not mount. I was able to install a dashboard widget called "maintidget" and was successful in running the daily, weekly, and monthly maintenance tasks. Can anyone help? Everything else works fine!!! All apps! Safari, Mail, iTunes, MS Office, everything works fine. Thanks for ANY help!

Previously, I had run verify permissions, repair permissions multiple times(from startup DVD) - no probems found. Deleted disk utility prefs. Run the maintenance taskes (daily, weekly, monthly). Nothing worked. But, I forget to check the drive for problems. So I ran disk scan. It found "invalid node" and repair disk could not do it. So, do I erase and do a fresh install or get DiskWarrior? I am running Leopard so I do not have Time Machine but I have backed up my documents, iTunes Library, iPhoto Library, etc... Another thing I found out the hardway is to sync all your bookmarks, mail settings and messages, etc... with .mac if you have an account. Any more suggetions?

Disk Images do not mount - Update to Lion on New MacBook Pro

Hi,
Just got my new MacBook Pro 2011 13 inch higher spec with 750GB hard drive today. Updated immediately to OS X lion via the up to date programme for free. Am in the process of restoring my applications that I had on my old computer that are on my external hard drive, however the .dmg disk images will not load properly. They go through the regular process of verifying then mounting the disk image, then the image appears for a split second on my desktop before disappearing again.
This happens even if i copy the disk image off of my external hard drive to my macintosh HD and try to mount from there.
This is really really scaring me as if I can't load all my old applications my new computer is absolutely useless. Please please could someone tell me what is going on!?!?!??!?!
Many thanks in advance,
Sam

Woke up this morning and tried again and now they all mount fine... Don't know how this happened but the only things I have done differently are trying to mount a dmg that was on my old computer over the network, and it mounted fine, then mounted other dmgs that were previously not working, and they are all fine too. I'm halfway through downloading software updates but all its done so far is download updates for iweb and itunes, and they haven't started running yet anyway.
With love from,
Confused.

Disk image will not initialize.

After downloading several times, disk image will not initialize. Dialog box -"The following disk images couldn't be opened Firefox 33.0.2 not recognized."
Mac OSX 7.5.2

Thanks for the reply - unfortunately I can not see the Firefox Disk image, the file that I downloaded shows up, but does not create the Disk Image required to begin the installation process.
I have re-downloaded the file from Mozilla several times with the same result.

External firewire disk partition will not mount

I have two external hard drives connected by a firewire to my 2002 G4 iMac running OSX 10.3.9. One is a 160GB and the second a 360GB drive.
I was out of the room when the area experienced a minor power drop in voltage and when I came back the iMac had the message to shut down and restart. When I restarted everything appeared normal until I realised that one partition did not mount on the 360GB drive. I ran Disk Utility to check the disk and it found some issues (I failed to write them down..) but Disk Utility appeared to fix them.
The disk has 2 partitions and only one of the two partitions will not mount (the second partition works fine!). Disk Utility says that both partitions check OK.
I have rebooted several times. I have removed all other external attachments and rebooted but still the partition will not mount.
I cannot see the partition in Finder. The second partition on the disk is available to see and use in Finder.
I have selected the partition in Disk Utility (grayed out) and tried the "mount" button but nothing happens. For some 18 months up until now the drive has worked fine although I did notice a couple of times it took a while for the drive to open up in Finder and other applications. I use that particular partition daily, it has approx 100GB used of the 150GB total space.
When I ran Disk Utility it comes up with a variation in the results compared with the partition that has mounted OK. The result of running "Verify Disk" is listed below. The only diffeerence between the two partitions is the first line of each volume. Does the ",0" following "Checking HFS Plus volume." for the first partition called "Genesys1" indicate anything?
DISK UTILITY REPORT

Any help would be appreciated.

Hello! Power failures are murder on disk drive directories as you have found out. Your best shot is to get DISKWARRIOR. It is the "gold standard" for these types of problems and can usually resolve the issue when Disk Utility cannot. As with any utility there are times when even it cannot fix things but it's the best there is at resolving such issues. Tom

Sparse Disk Image will not open along with encrypted document

I have two problems. I created a sparse disk image of my documents folder and encrypted it but recently when I select it and double click it to open it up nothing happens. I put in my password and in the finder window it shows the image but no documents folder will open up.
I ran disk utility and disk warrior and all is okay on my hard drive. I did burn a CD of the files in this folder so I do have a backup but wondered why it will not open up now, any suggestions?
The second problem is in this same folder, I created a word document years ago when I had my old G3 iMac and used at times MS Word 2000. At the time, I locked this Word document, and now it is encrypted and it won't open up. I can't remember the password used back in 2000 and so this document is encrypted and I don't know how to decrypt it, any suggestions.
I do know there are software programs to delete passwords in MS Word and that they will decrypt my document, but the ones I try to download won't work. Any suggestions.
Thanks,
DaisyMay

A follow up to my MS word document. I found that I created the file in MS word 2000, and I used the Apple File Security for OS 9 to encrypt it. I can't remember the password, and I do not find anything in the key chain listing.
I have Pages 08, but I don't think I can use it if I can't remember the password to unlock this old document. Is there a program to decrypt this without a password?
Thanks,
DaisyMay

Disc Image will not mount after format

I am trying to create a disc image from DVD Pro so that I can burn the final project at a low speed to avoid burn errors. Whenever I try to burn the image to DVD in Disc Utility it says that the file is not recognized. I have even tried to start the project from scratch and still am getting the same error message. Another weird thing that DVDSP is doing that is odd is when I am build and format, the log shows a ton of error messages saying that random files will not be included on the final DVD. Please help, I cannot figure oout what I am doing wrong.
Thanks,
Leon

Leon:
Warning: The file ‘2007KIAC_BBTOURNY.layout’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
Warning: The file ‘VOB_DATA.LAY’ found in the VIDEO_TS or HVDVD_TS folder will not be included in the final disc.
These are standard wraning. Nothing to take care about.
After deleting the old build empty your trash and try again. If DVDSP ask to reuse, you must be building to another location than where you think. Check that.
Hope that helps !

Time machine - "the backup disk image could not be mounted"

SInce a few days, I am unable to backup via Time Machine.
I always get the message:
TIME MACHINE ERROR

*_"The Backup Disk Image Could Not Be Mounted" (Console - “Failed to mount disk image”)_*
First, it is important to distinguish this error message from another, similar Time Machine error that states “The backup volume could not be mounted”. This is important as the causes and cures for these two errors can be very different.
Consider each topic below separately. When one option does not resolve your issue, then move on the next one.
*Unmount the Backup Disk Image* (TC)
If, for some reason, you have manually mounted the Time Machine backup disk image (sparsebundle), or Time Machine failed to eject it after the previous backup, subsequent backups may fail. (Console - “Failed to mount disk image”… “Backup failed with error: 21”)
Eject the backup disk image (white drive icon) by either clicking the little Eject icon to the right of the disk image in the Finders’ Sidebar, or Ctrl-Click the drive icon on the desktop and select “Eject” from the contextual menu. Now try backing up again or launching Time Machine to view previous backups.
*“Disconnect All Users…”:*
If your Time Machine backup drive (“Backup of Users Computer”) is mounted on your desktop or in the Sidebar of the Finder window. then Time Machine may think the drive is already in use. Alternatively, if the Time Capsule hard disk has been recently accessed by a Windows machine, it may not have fully relinquished control. Do the following:

Select “Disks” at top of window.
Click “Disconnect All Users…” at bottom of window.
Close the Airport Utility.
Now try Backing up again.
“I got it resolved. Apparently it had to do with one of the files being open on the disk from the drive. I had browsed the disk with one of my windows boxes here and it must have left one of the folders "open". Anyway, I rebooted the TC and we are good to go now.”
*Proper Computer Name* #
Make sure your computer has a proper name. Go to System Preferences --> Sharing. Time Machine needs to differentiate your computer from others on your network (i.e. "Bills MacBook" or "Office iMac"). If the "Computer Name" field is blank, create a name. Realize that if this step is necessary, you will likely have to start the Time Machine backup process over again and do another full initial backup.
According to this article, [http://support.apple.com/kb/TS1760], Time Machine may experience problems if your computer name includes certain characters. Make sure the computer name only includes ASCII characters from the following set.

Time machine error: The backup disk image could not be mounted

Time Machine worked OK for several months. Now I get this error every 10 minutes or so.
I unplugged Time Machine capsule and "Change Disk" in Time Machine options.
Nothing helps, I continue to get this error.
I cannot Enter Time Machine either. "Connecting to Server, Connecting to backup" does not work.
Help please because I will probably have to archive and reinstall Leopard. I need the backups,
Christine

Fix to the problem-- Back up Disk Image could not be mounted

In order for TC to backup your entire HD it needs to create a Disk Image on your Mac. For example you would have seen your computer do this operation if you ever installed programs on your Mac computer.
I actually had this same problem and I searched the forum for answers. One fix that I found was that your computer might actually not be named. To fix this click on the apple in the upper left hand corner and then go to >System Preferences. Then click on >Sharing, after you do that you will see Computer name at the top. Type in whatever name you like for that part and then also turn on file sharing by clicking the box next to it below.
The other fix to this problem...which was actually the solution to mine, was that during setup 2 files for a Disk Image mount were created onto the Time Capsule itself. It is only supposed to have one. *In order to fix this problem-->If your Time Capsule is setup so it allows file sharing you should be able to see it as a connectable disk drive in your Finder window under sharing. Click on Time Capsule from there and enter in you password. You should now be able to search though the files on it. Since this is your first time setting it up there should only be one file visible on the Drive and that one file is what creates the mounted Disk Drive...(What I found on my Time Capsule drive was a file labeled with a bunch of numbers and then a Shared folder and then another file with a bunch of numbers in that). For me it actually turned out that the first file was not working properly but the one in the shared folder was. So I deleted the first file and dragged the second file that was working out of the shared folder and into the main part of the Time capsule Disk and then deleted the shared folder.
The way you can tell which file is the correct one is by double clicking it, if you get an error message right away, delete it. If it starts to load, then that is the file you should keep. After I did this mine worked fine and backed up my disk last night. I hope this helps

I have had the time capsule since it first shipped. In that time I've TWICE suffered a corrupt backup disk image (which I checked by trying to hand mount it by selecting the TC under sharing, and trying to open the sparse image - each time it failed and reported an unfixable error). Each time this occurred after the machine had been working flawlessly for 3 or 4 weeks. This makes the machine completely useless in respect of Time Machine. The disk seems to check out as I've just zero'd all data and it did not report a fault, and I have now reset the capsule (using the hole at the back) hoping that perhaps I can give it one last shot. It seems to me that basing these backups on a diskimage is a bad idea because in principle you could lose a single bit and the diskimage will not mount (unless there's redundancy in whatever header information etc. it uses) and then you lose ALL your files. I would have thought that backing up as individual files would be more robust to occasional corruption. Anyhow, this is all very disappointing, and I've been in touch with an Apple rep I deal with to seek advice. Apple need to fix this. I don't know if it's a problem with Time Capsule, or Time Machine.

Disk Image Won't Mount - Reason: Device Not Recognized

As I've searched the discussion forums, I've seen plenty of postings for "Disk Image Won't Mount" and for "Device Not Recognized" but not the way I'm seeing it on my laptop.
After a backup and restore, my mac will no longer mount any... and I mean any images. I have downloaded several security or software updates from different vendors and each .dmg file will not mount. I still have the .dmg files in hopes that after I get this problem solved, I'll be able to install them, but...
It always gives the same reason for not mounting and I'm at a loss on what to do next. I've run Software Update hoping it will be a quick fix, but have had no success.
Any suggestions?

I have a similar problem. Using FireWire disk mode, I put a disk image of my entire iBook onto my iMac as a back-up. (For an unrelated problem, Apple told me I needed to erase my iBook completely and do a clean install of the system.) Well, I screwed something up. I don't know what exactly--maybe I didn't "put away" the device correctly, but the next day when I flipped on my iMac, the disk image of my iBook was just gone, and not to be found anywhere. I finally succeeded in restoring the image using TechTool, which scanned the entire volume of the iMac for directory information. And it's all there, because the img file is more than 10GB. But when I double-click on it, I get the following error msg: "The following disk images failed to mount...reason--not recognized." I've checked the app it's supposed to open with, permissions, and run Disk Utility volume repair. No dice. Any ideas??? Did I mention that this is EVERYTHING I had on my iBook???

Disk image could not be mounted - error

Ok, I've been using TC (Time Capsule) for a week now, and it was working great. Then in the middle of the week I decided to change the password for TC. Now when I reboot my iMac, TM (Time Machine) will not back up and it gives me a failed - "the backup disk image could not be mounted" error. Then if I go to the AirPort Utility and reboot TC, all of the sudden TM works. Couple of days go by and when I reboot the iMac again, I have to do the whole process again of rebooting TC to get TM to work. Has anyone encountered this issue? I think I explained it well...

This happened to me too.
I called Apple (they'll talk to you for 90 days after you buy your Time Capsule and solve all your problems.)
The solution was to rename the Time Capsule. Here's how:
Open Time Capsule in System Preferences, click on Change Disk, and choose None from the list.
Open Airport Utility (choose Go from the Finder Menu, choose Utilities from the list, then Airport Utility), highlight your Time Capsule when its picture appears in the left side bar. Click Manual Setup in the main window, then the Disk icon on the top. Highlight the lower of the two names Time-Capsule Disk and change it to something short and one word, like Disk. Click Update, then close Airport Utility after your Time Capsule restarts.
Go back to Time Capsule Preferences and click on the Choose Disk button in the center of the main part of the window, then choose your newly-named Time Capsule (If you see more than one Time Capsule name there, restart your computer first).
This solved it for me. The guy on the phone said that in the tech help people's experience the Time Machine program doesn't like long names or ones with "higher" ascii characters in them.
Good luck.

Time Machine Error Message: "The backup disk image could not be mounted"

I just installed Time Capsule and the initial back up was going smoothly. Now
all I get is a and the Error message "The backup disk image could not be mounted". Can anyone help me troubleshoot this problem? Thanks.

This works, if there is no corruption in the sparse image. But after weeks of backups, my sparse image on a USB disk attached to an Airport Extreme was corrupted.
I am right now repairing it by connecting the USB disk directly and using disk utility. It recovered the file system and is not rebuilding the B-Tree. I hope that works, otherwise it will have to be disk warrior...
On Time Capsule, I have heard folks having success with attaching the image, and then repairing it:
hdiutil attach -nomount -readwrite /path/to/sparse/image
Your mileage may vary, but you do not have a lot to lose in this circumstance...
This functionality should really be in the Airport or Time Capsule, or at least Disk Utility or Airport Utility.

Disk images will not mount
