OS X V10.7 Lion :: Unable To Mount Disk Image

Feb 28, 2012

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.

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.

OS X V10.5 Leopard :: Disk Image .DMG Unable To Mount / Attach - Not Recognized?

Jul 3, 2012

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.

OS X :: How To Permanently Mount A Disk Image

May 26, 2009

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?

Software :: Cannot Open DMG Files - Disk Image Failed To Mount

Feb 27, 2010

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/

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.

OS X :: Unable To Mount LaCie Little Disk 320gb?

Mar 15, 2010

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).

Windows On Mac :: Unable To Mount Partition - Grayed Out In Disk Utility

Dec 26, 2010

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.

OS X :: Unable To Mount External Drive / Repair Disk Permissions?

May 20, 2009

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?

OS X :: Unable To Open Image Files Saved To Disk

Aug 7, 2009

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.

OS X :: Converting CDR To ISO / Bootable CDR Disk Image To An ISO Disk Image

Sep 10, 2009

Apparently, there are two ways to convert disk images in CDR format to ISO format:

1. Rename diskimage.cdr to diskimage.iso


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.

OS X V10.7 Lion :: Cannot Restore DMG Image Stored On NTFS Disk?

Apr 10, 2012

My MacBook Pro has OSX Lion on it. I have created a DMG image of my starting volume using Disk Utility. The image was saved on an NTFS formatted external USB disk. I used Paragon NTFS for Mac to activate writing on NTFS partitions. The image was created, tested and it mounted fine. It's size is 105GB. 

I have restarted the system and am accessing Disk Utility from the recovery partition that OSX Lion creates. Disk Utility can see the NTFS disk and I can choose the DMG image as source and the partition on the internal hard disk as a target without problems but when I press the restore button and the Image scan process is going to start I just get an error that says "Unabke to scan Mac-OSX HD. Resource busy". When I try the SCAN BEFORE RESTORE command on Disk Utility on the image I am getting "Unable to scan MAC IMAGE.DMG (Not such file or directory)". 

I have already erased my startup disk and really need to get this image back in place. It is the only backup I have of my data.

Mac OS X Lion Server :: Creating A Disk Image Of A RAID 1 Setup?

Jun 20, 2012

I have just finished setting up my first Lion Server from scratch on a Mac Mini with dual 500GB Drives which I set up as RAID 1. I have the server exactly as I want it, and before the users start logging on and it gets all screwed up I would like to create a disk image of it so that I could reinstall if necessary w/o having to start from scratch. 

Is the process of creating a disk image for a RAID 1 any different than that of a disk image from a single drive set up? Will Disk utility just see this as a single volume or will it want to create a disk image of the entire RAID? i.e will the disk image be 1 TB (500 GB x 2)? And when it comes to reimaging my RAID, will I just recreate a RAID 1 and be able to write to it from that disk image?

Software :: Unable To Backup Via Time Machine / Backup Disk Image Could Not Be Created

May 1, 2008

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?

OS X V10.7 Lion :: Why Does Screen Saver Prompt For Secure Disk Image Password

Mar 17, 2012

I go into System Preferences->Dektop & Screen Saver.  As the program "loads" availabe image sources and such I get a pop-up requesting a password to my secure disk image. Yes, I have a secure disk image in my home directory. Yes, the secure disk image is currently "locked" (Not mounted in finder). 

I click cancel (a few times, probably 2 maybe 3 times) and things continue along fine. I select a photo source that I want for a screen save and exit peferences. I then go an start the screen saver (I'm using Hot-Corners). I get the message "Looking for pictures....." for , well...basically forever... 

Sure enough I touch the mouse to leave my screen saver and there is the pop-up again.  Asking for me to unlock my secure disk image. 

I thought this might be related to Spotlight.  I tried reading several threads and have gone as far as taking my entire hard-drive/volume and putting it into the "Privacy" tab under spotlight. 

how I might get it so the "Desktop & Screen Saver" stop prompting me to unlock my secure disk image?  (WITHOUT having to make sure the disk image is unlocked before I sleep my screen or open the screen saver utlity) As always, I am only speculating that this is Spotlight related so that could be a red-herring....

OS X V10.7 Lion :: Copy Image From Browser To PowerPoint, Get A Link Instead Of Image

When a user copies an image from a browser into PowerPoint 2011 he gets text of a link back to the image, not the image itself. But if he copies from a browser into Word he gets the image, and can then copy the image from Word to PowerPoint. Same results with both Firefox and Safari. Behavior is new so I assume it relates to recent software updates but user does not recall accepting any.
