OS X :: Unable To Mount Backup Disk Image?
Jan 6, 2009
for the past month or so my automated backups with time machine/time capsule have not been working. Every so often the following error message pops up:
"the backup disk image could not be mounted"
in troubleshooting, i have tried to mount the sparsebundle image directly but without success. from reading around a bit i can see that others have had this problem, and that one solution is to delete the sparsebundles and start again.
but that of course means losing all my archived backups, which i would rather avoid.

Yesterday I downloaded and installed Lion. After a while I tried to open one of the disk images that I have stored on the harddrive, which worked to mount prior to installing Lion. While attempting to open it, the process fails and gives the error "no mountable filesystems". I have searched for the error on the internet, and there does not seem to excist a solution to it. However, all the people with the same error, whcih did not have a solution, did not seem to have a similiar problems. Their problem lied with not being able to access disk images downloaded from the internet, while my disk image already excised on the hard drive before installing lion.
Many of the files and documents on the disk image are irreplaceable to me. I can not stress how important it is for me to recover them. If I am not able to do so, it will result in a massive economic loss.

After a fatal mac crash (PPC 10.5) i had no option but to reinstall the OS (10.5), i obviously didnt reformat the drive in the hope that i would be able to recover some if not all of my data. Using various tools i was happily able to recover most of my data successfully, including 3 AES encrypted Disk images of around 30GB in size each.
I didn't hold out much hope for actually recovering the data inside the dmgs, although after some fiddling i was able to recover 2 of them fully after receiving the no mountable file system error, i dont know how i done it but nonetheless i dont appear to have lost any data from those two dmgs whatsoever. Now the third dmg (also about 30GB in size) never gave me the no mountable file system error and instead returns the error: unable to mount: not recognized. Im pretty sure that my data is still there somewhere due to the sheer size of the recovered file, tied with the fact of the success of the recovery of the other 2 disk images. I have read every post i could find on this site and have trawled the web tirelessly looking for a solution to this, but have yet to find anything that even comes close - the closest i have found was a post on this forum where it would appear an apple engineer was able to recover most of the data using some sort of magic.
I am not in a position to pay for professional data recovery and besides i would love to see a solution to this problem appear somewhere on the web. I have tried the usual, rebuilding permissions, mounting on another machine (imac G5), resizing with disk util, repairing with disk warrior, converting to ISO - all which return the same error - not recognized! I have tried every terminal command i have found on the web, although decyphering some of the information is a little out of my remit and my knowledge of HEX is limited. I haven't yet tried Toast, basically because i dont have a copy, but it would be my guess that this would return a similar result. Incidentally when i recovered the original data, there were some small (what appeared to be dmgs) files around only maybe a few Kb each with part of the file names of the original files, i'm guessing these maybe the headers or something like that? although i didn't have to do anything with them to get the other 2 disk images working again.

I was a PC user who recently moved to mac. I have a macbook (intel 2.2GHz, 2GB RAM, 250GB HDD). When I was using PC, I backed up all my data to a network storage device (Buffalo LinkStation 250 GB connected to a 802.11g netgear router which is supplied by Sky) using a program called SmartSync Pro, which worked very well. Although I can connect to and mount the Share folder on this drive when the macbook is connected to the network, Time Machine will not back up to it. It wouldnt even recognise the disk on the network.
So I went onto the trusty internet, and found that you can get time machine to recognise the Share folder. (This was obtained from: http://blog.imulus.com/george/software/using-leopard-time-machine-to-backup-of-a-network/)See my comment on their page at the bottom, number 66.
It recommended entering the following in to the Terminal: defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
Before attempting backup I have to go into "Network" and select the Share folder by double clicking on it. This seems to mount the volume. After this, it can be seen in Time Machine as a potential backup destination.
However, this method does not work for me. Time Machine "prepares" for a while, then gives the following message: Time Machine error. The backup disk image could not be created.
More internet searching took me to macosxhints which suggests creating something called a sparsebundle image on my local system. (http://www.macosxhints.com/article.php?story=20080420211034137) Have not tried this yet as I thought it would be prudent to seek some help first.
Apple have deliberately disabled the ability for Time Machine to back up to network attached storage, (except of course to their proprietory Time Capsule):
Is this because time machine requires a network faster than 802.11g?
Is this because a time machine backup to a network attached storage device is unreliable and the data is corrupted?
I dont want to shell out more cash for a time capsule. I would prefer not to have to hardwire to an external drive (which I will also have to go out and buy). Any thoughts?

I have all my OS X applications that come with your mac on a seperate .dmg file, that's just how it happened. I'm not sure how it happened, but when I took my computer home, it just installed like that. I bought the iMac ex-display from PC World last august and it didn't come with any documentation, reboot disks or an apple remote. They say they don't have them with them, but they obviously do.
I keep forgetting to mount the .dmg every time I reboot, because I'm a klutz and becoming old at a young age. I was wondering if there's any way to automatically have the mac mount the disk image?

I'm using a 2GHz PowerPC G5, OS X 10.4.11, with 1 GB on one dimm. I cannot open ANY .dmg files. I have tried clicking the image, and also on a clean download used "open with" each time I received the following message The following disk image failed to mount
Reason: Device not configured
I have followed the instructions in this thread:- Disk image failed to mount: Device not configured.
Firstly Run /Applications/Utilities/Disk Utility.
Click on "Macintosh HD" in the left column and then press the "Repair Disk Permissions" button.
Delete the file called /System/Library/Extension.kextcache
Delete the folder called /System/Library/Caches/com.apple.kernalcaches/
Restart
That made no difference. I then tried bobw's advice here Panther - Disk Image "mounting Failed" Panther - Disk Image "mounting Failed". That made no difference. I have since gone on to justanswer.com and the advice I received was to do an archive and install and then a full combo update.

On my old macbook, I installed vista and everything worked fine. I just did that on my new macbook pro. It runs fine and all, but the Bootcamp HD isn't showing up on my desktop under my Macintosh HD. I went do disk utility and it verifiys the disk, but repair just does this:
I try to mount the image, but it fails and wants me to try repairing, which as you see in the picture doesn't work. Any ideas?

I use Backup (the Mac app) to backup some things to my iDisk and others to an hd connected to my airport extreme. It works fine, except for that when the app appears (each day) for the scheduled backup to the network hd, (it sits there waiting, saying ''waiting for volume... and the name of the disk"). I have to go to the finder, open a window, go to 'All' under 'Shared' locations, choose the network hd, click on the folder (there's only one one the disk) and then, and only then, will the backup begin. Is there any way for it to just be able to find the folder by itself and perform the backup without my having to find the folder for it every time?

I want to use Time Machine, but I don't want to have all my data sitting in the open on an external drive that someone can just carry away. Can I make an encrypted disk image, and have Time Machine use that as the backup volume?

So my current backup strategy uses two western digital external hard drives. The first I have permanently connected to my iMac using Time Machine. On the second I use CCC to backup to every week and keep it in the trunk of my car as an offsite backup.
Just had a couple of questions to make sure I'm prepared for the worse...
- What temperatures can hard drives survive at? Is there a risk of it overheating in my car?
- I've read about some issues with CCC's backups. I'm currently backing up to an encrypted disk image - is there any way to verify the backup? If I just cloned the drive instead so it was bootable is there any way to encrypt it? And is Super Duper more reliable?

The following error message just popped up: "The backup disk image “/Volumes/Data/Robert's Office iMac (2).sparsebundle” could not be accessed (error -1)." I'm running a late 2009 iMac; upgraded to Lion about a week ago. It seems to have done the Time Machine backups fine for the last week.The only other recent change was to reset my iCloud account so I could sync with my iPhone.

Recently I haven't been able to backup. Why this is? Not too sure. I don't remember changing any settings or anything recently but within the last 2 weeks or so I haven't been able to backup at all. When I start backing up it says "preparing backup" then an error message pops up that says "The backup disk image could not be mounted".

I'm just curious as to what everyone's backup strategy for Windows is? I've been exploring the options of the Windows XP Backup utility, but I also like being able to have a entire disk image with Winclone. However there's no way to back up incrementally with Winclone. I'm sort of mum on both options, or would like to know if there's a better option? So what have the other Boot Camp participants been doing for a Windows backup?

I bought the LaCie Little Disk 320gb about a year ago and it has been working fine till recently..
The problem that I have is that the laptop that I use (Powerbook G4) doesn't recognize the HD anymore..
I have tried all cables (both firewire's and the usb) but nothing works..
I did try it on multiple computers (macbook's / imacs and even some windows computers) not one did recognize it.
(well the windows computer I used it on did recognize it but it cant open it and Windows Explorer stops working till you pull out the HD).
The only think I can think of is that I pulled out the HD to many times without safely removing it first..
I got a lot of data on the HD and I'd (offcourse) like to get it back,
I haven't been to the store yet (going somewhere this week).

I use Carbon Copy Cleaner to backup. I've set it to backup to a sparse, rewritable disk image. If I, say, delete a file, then do another backup, will the file I deleted still be in the folder it was in, or will it disappear as if the backup was cleared and redone?

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?

I can boot into bootcamp with no problems. I have been wanting to be able to open the bootcamp in Parallels. Here is the issue:
1. The partition 'disk0s3' is greyed out in Disk Utility. It is not mounted. Mounting does nothing.
2. For reference, the Windows 7 is formatted as NTFS. It is a Windows 7 64-bit install
3. Verify disk does the following:
Verifying volume "disk0s3" ** /dev/disk0s3
Invalid BS_jmpBoot in boot block: efbbbf
Error: This disk needs to be repaired. Click Repair Disk.
4. repairing does the following:
Verify and Repair volume "disk0s3" ** /dev/disk0s3
Invalid BS_jmpBoot in boot block: efbbbf
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can"t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
I have stuff on the Windows partition that I don't want deleted. I'm really stuck on this -obviously, I can just continue to boot into bootcamp, I just would rather open it from Parallels. I'm not sure what or if I made some mistake in setting up Bootcamp, I thought I followed the directions to that. I do know I formatted the partition as NTFS during the install - as I think Windows 7 requires it. I have tried installing NTFS-3G - it is installed, but didn't do any good when trying to mount the drive.

I'm having a series of problems. First some intermittent audio problems with Garageband, then, then some external drives won't mount, and now I can't sync to my disk from the iMac. I've run Disk Utitilies a few times and when I do Verify Disk Permissions, it finds a list of things to fix, I then hit Repair Disk Permissions and it fixes them, and then hit Verify Disk, and it say the disk appears ok. When I do Verify Disk Permissions again though, it finds another long list of things to fix. Is this serious? What should my next step be? Should I reinstall the entire system?

Error message "The backup disk image could not be created." I have tried everything I have found online in the community from TM full reset to changing my computers name. Anything else I can try? I am using a Seagate external HD with a connection through my router. I spent an hour on the phone with seagate and everything is ok on the HD end. TM sees it and it is mounted but cannot go any further

All of a sudden my computer (imac, 10.4.11) won't let me open images downloaded from digital cameras (I've tried several - so it's not the cameras). I get the following error - "Couldn't open the file. It may be corrupt or a file format that Preview doesn't recognize." Also the same basic error when using Photoshop and Fireworks. I can open files still on the camera, or saved to a CD - just not anything dragged to the desktop. I can still open pictures which had been previously saved - but nothing new. I ran the Repair Disk utility, which found and apparently fixed an Illegal Name error on the hard drive, but the problem still persists.

Apparently, there are two ways to convert disk images in CDR format to ISO format:
1. Rename diskimage.cdr to diskimage.iso
Or
2. hdiutil makehybrid -iso -joliet -o diskimage.iso diskimage.cdr
The first method is really quick while the second method takes quite a long time. Do the two methods yield the same ISO file? In particular, I would like to convert a bootable CDR disk image to an ISO disk image.

I am getting the following error from Time Machine when doing my first backup. The startup disk being backed up, and the TM disk are both the same size.
Macintosh HD: 465.44 (total); 393.99 (free); 71.45 (free)
Time Machine: 465.44 (total); 465.29 (free)
The Time Machine error is: Quote:
"This backup is too large for the backup volume. The backup requires 472.7 GB but only 465.3 GB are available." why would this be? Other disks are excluded from the backup, and Time Machine is telling me that it needs more space than it actually needs. What should I do?

my usb 2.0 removable flash disk had a problem. i reformatted it and while in the process it failed. then after that my usb can't be detected by mac but i can see it in disk utility. i tried everything in disk utility. [URL] that disk2s1 when i try to verify, or even repair it something will say that ** /dev/disk2s1 could not read boot block (Permission denied) Filesystem error: verify or repair failed
i can't mount it too..when i hit the mount icon it would say try first aid on it first or verify or repair and try again. i've searched everything in the net but i can't find something.
ah..and when i insert my usb in windows (desktop) the usb will be detected but i cannot open it.. the pc will hang and i can't even get to see its properties in windows.
