Recover lost disk image backup file

I think I may have screwed myself, but basically I am trying to get back the sparseimage that was lost when I tried backing up my internal hdd to an external using SuperDuper. My issue is that the external HDD was formatted as NTFS so I was using the NTFS-3G driver for write access. So something must have happened when I tried to remount and and the file was lost. This was after running a checkdisk on a windows machine to get the ntfs partition to show up again. So basically I am trying to figure out what kind of software I could use, if any, to get this 80gb disk image back. Also I should note that I used compression when backing up the disk image so I am thinking that this might make my problem even more complicated. Any help or advice would be appreciated.
Thanks.

Cool, Ya that program did a pretty good job. It seemed to have found my lost directory structure. However like I mentioned I think I'm running into an issue with the compression that was ran on the image after backing it up. A feature that I am now regretting using. Because when I try to recover a file, like a jpg, preview says it can't preview the file. And opening plain text files gives me what appears to be binary or hex etc. So I am thinking I am running into issues where the files are still compressed and I need to figure out how to decompress them first before I can fully recover them. I was considering trying to just recover the whole directory structure and renaming the the top folder to a .img or .dmg file but I am not sure if that will work. Any ideas?
Thanks again.

Time Machine cannot find internal backup disk.Lost disk image in Finder for internal backup volume. OS 10.7.3.

Lost disk image in Finder (Desktop) for backup disk on Intel Mac Pro OS 10.7.3. Time Machine cannot find the internal backup disk. The volume is grayed out in Disk Utility, though it CAN verify the volume. How do I get it back on my desktop?

First, restart the Time Capsule by disconnecting the power adapter and reconnecting it. If other devices on the network can see it, you can skip this step.
From the menu bar, select

Recover lost deleted corrupted music files tracks from iTunes match icloud

Just spent an hour on Apple's tech suypport line, all to figure out how to recover lost/deleted/corrupted music files/tracks from iCloud / iTunes Match. Here's how to do it:
ASSUMPTIONS: You're in iTunes on your computer, logged into your iCloud account.
Within iTunes, in the left-hand pane, select your Music library. Alll your tracks should appear in the right-hand pane. Those that are missing from your disk should be marked with an asterisk icon to the left of the track. Do the following...
...select all the missing/lost/deleted tracks (using the option button), and hit the delete button.
NOTE: when the delete dialog box comes up, make sure you do ***NOT*** click the "Delete from iCloud" selection!!!
...once deleted, select all the same tracks again, then hit the right mouse button, then select "Download".
All the tracks should start downloading, one by one, from iCloud.
NOTE: If I were you, I'd perform this operation on discrete chunks (no more than 500 at a time), just to be safe.
Good luck!

You can also recover the missing tracks from the backup you are keeping on an external HDD. You are backing up, aren't you?

Reinstalling, Migration Assistant, Disk Image backup

I am in the unfortunate position of having to reinstall Tiger on my iBook. The disk image containing my backup files turns out to be non-bootable.
After reinstalling Tiger (I have the updates up 10.4.10 on disk), will I be able to use Migration Assistant to replace the folders created by the re-installation with the same folders containing my backed-up information from my disk image backup?
If I can't use Migration Assistant, how should I best get my backed up files on to the iBook...simply replace the folders? Any suggestions to reduece the pain appreciated.
thanks, Michael

"...After reinstalling Tiger (I have the updates up 10.4.10 on disk)"
All you need is one update, the 10.4.10 combo updater for ppc.
"...will I be able to use Migration Assistant to replace the folders created by the re-installation with the same folders containing my backed-up information from my disk image backup?"
When you use Migration Assistant you are connecting to another Mac via firewire and transferring pretty much all your files, applications and settings.
:...how should I best get my backed up files on to the iBook..."
You may have to do file by file unless someone jumps in here with a better idea.

How cam i recover a lost Disk Image?

I tried creating an encrypted 30GB disk image but got impatient and clicked cancel while it was still creating. Although it finished creating and even asked me to create a password, I can't seem to find it anywhere. My 30GB of space is gone. How can i recover it?

Thanks for your comment.
I tried your suggestion. It was not successful. However, I did "Shut Down" then unplug the power from my new WD external hard drive used for "Time Machine." When I completed a Start-up the offending and Time Machine Icons were gone. Upon re-power and re-Start both Icons were back. The offending Icon was not effected by dragging to the Trash.
FYI.
I did subsequently find the file type as "Volume." However, shouldn't that operate [drag to the trash] in the same way as a DMG file?
I also unlocked the file. It re-locked and re-appeared automatically.

Disk Image backup

I was curious if I could make an exact image of my HD with all the software i have installed and use that image in the event i need to rebuild my machine. So, for example, OSX, photoshop, final cut and all directories on the HD so I could easily haver this backup. Can it be done if i use the disc utility?

To answer your question, it can be done with Disk Utility. You have to start up from your Mac OS X Installation Disk, and run Disk Utility from the Installer menu (because you can't make an image of the disk you are starting up from using this method). Note: If you have an external (or other) drive that has Mac OS X installed, you can start up from it and run Disk Utility.
Select the volume you want to image in the sidebar, then...
File menu > New > Disk Image from {name of disk}
Save the Disk Image file to another drive, such as an external drive.
To recover, run Disk Utility the same way. Go to the Restore tab. Click the Image... button to get the disk image into the Source field. Drag and drop the target volume from the sidebar to the field called Destination. Click the Restore button. I've done it a few times and it works fine.

Disk image backup freez

I like to make a disk image of the partition with the operating system on it from time to time as a backup to an external hard drive. Works fine with my Powerbook G4 but the last couple of times I've tried to use disk utility to make such a disk image for my iMac it freezes. I have to shut the computer down with the button. It might actually finish but I don't know how to tell!? I'd rather it just work like it is supposed to. I just to the operating system partition. I do read only and no encryption. I do this all the time but now it doesn't work. I always throw the trash out, do a repair permissions and a disk repair before I do this. The first time this froze I did have an actual repair of the disk. It said it fixed it. That does worry me. Any ideas? Steve (p.s. I am doing this from the boot disk that came with the computer.)

Recovery Software for Disk Image Backup on External Drive

Hello. I am currently running OSX Yosemite on a mid-2010 Macbook Pro. However, before I upgraded from OSX Maverick I installed a SSD as a boot drive and moved my original Toshiba HDD to the optical bay for media storage. Before the installation, I purchased a LaCie 1TB external hard drive, formatted it, then dragged the entire Toshiba HDD image from the desktop to the external HD. That image is visible on the external HD but is inaccessible by Disk Utility, whether I use it from the HD, the SSD, or the Installation DVD. All scans and attempts to mount and open the image fail. I realize now I made a mistake by not cloning the Toshiba HDD onto the external HD before starting but the image size (on the external HD) is 187GB, which corresponds with a somewhat compressed ~220GB (the original size of the Toshiba HDD). Therefore, it seems as though the files are present and intact, albeit currently inaccessible.
Is there any way to recover the files from the disk image, i.e. via Data Recovery Software such as Data Rescue 4, Stellar Phoenix or R-Studio? Alternately, could I use the same software to recover the now deleted files from the wiped and reformatted Toshiba HDD? I'm having trouble accepting that the 187GB of data on the external drive are really gone, as it represents over a decade of media collection and contains many irreplaceable files. I'm hoping there is something that can be done before spending a lot of money on clean room data recovery services. Please help!!!
Thank you in advance as any and all advice is very much appreciated.

General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

Backup file corrupted- How do I recover or locate older backup files?

I synced my original iPhone (with 2.0 software) a few times last night to make sure everything I had on the iPhone was synced to my computer before I restored it, and sold it on ebay. It backed up the iPhone a few times and always wanted to restore it everytime. Well the last time I attempted to sync the iPhone I interrupted the backup process by 'x-ing' out of it during the sync. Now I am trying to get my 3G iPhone synced with the backup of my original iPhone and it is saying that the file is corrupt. Obviously this is because I interrupted the backup process.
So my question is: Is there a way for me to locate an older backup file that may only be an hour older than the corrupt file?
In the preference settings in iTunes I can see the backup files for my phone, but it only lists one, which is the corrupt one. And I searched the finder for recent files, hoping I could find the corrupt file, locate the folder its in and there find older non-corrupt files. Alas, no luck.
I've already restored the original iPhone so the info is gone from that phone. Is there any hope of finding a non-corrupt backup file? Please help.

You can find your backup file here:
/Users/YourUserName/Library/Application Support/MobileSync/Backup/
It seems that iTunes lists all of the ones that are in that folder.
I just lost my backup, too. More than a year's worth of settings. I can't find any way of "fixing" the corrupt backup. It seems that photos are gone forever, if they weren't imported into iPhoto, but I did find this software to recover notes, sms, and call logs:

The developer seems like kind of a passive aggressive borderline extortionist, but the software seems to work.

Disk Image (.dmg) files no longer mount

Since updating to 10.4.9, I cannot mount disk image files. When I double click on them, I get an error dialog from Finder which reads, 'The Following disk images failed to mount.' Reason: 'Device not configured.' I suspect that some essential software, 'Disk Copy' and/or 'Diskimagemounter' did not, for one reason or another install with the rest of the update. My computer did crash when the update was almost complete, but after a restart, everything seemed to work OK, except for not being able to mount disk images, which in this age of downloadable software basically makes your Mac dead in the water. Any solutions, suggestions would be greatly appreciated. Thanks all!

Your Mac crashed before the update installation process was complete and before the prompt to restart?
If so - Houston, we have a problem. ;~)
Did you check your boot volume for any directory problems with Disk First Aid repair via Disk Utility when booted from your Tiger install disc immediately before the install and did you quit all running applications before the install?
Regardless and as a first step, check this link for system troubleshooting procedures and when doing so, follow all steps/instructions in the order provided.
http://www.thexlab.com/faqs/repairprocess.html
Test if this resolves the mount disk images problem since you should download the 10.4.9 Combo Update and re-install 10.4.9 since your Mac crashed before the install was 100% complete.

Disk Image/Original File (iDVD 5)

I just finished saving a iDVD Project as a Disk Image. I know you can move the disk image file to another computer for burning. Also you can create multiple copies of a DVD from a disk image.
This leads up to my question(s)...
When you have created a disk image, What should you do with the original file if you have really no use for it?
Do I need to keep the original file for some reason?
Should I trashed the original file to save hard disk space?
Thanks in Advance!
Imac G5 Mac OS X (10.3.7)

Susan, just as a point of protocol, new questions ought to be posted as new topics. Anyway, that said...
Ths disc image is a file, like any other file. It's just big. So to get it to the other Mac, either use the network (I'm assuming the machines are networked!): Click the network icon in the finder sidebar, click the host name of the other Mac in the finder window, and go through the steps of connecting as a remote user. (Depending on how the network is structured you may have to poke through some folders to find the other machine.) Once you have the remote share mounted, it's just a drag and drop Finder copy.
Your alternative is to plug in an external firewire or USB disk, copy it there, carry it over to the other machine, and copy again.
On the other machine, you burn the disc image with either Disk Utility or Toast. Start up Disk Utility, and select File->Open Disc Image. Then select the disc image in Disk Utility's sidebar and click the burn button. A similar procedure applies with Toast - select the disc copy mode and then select the disc image option.

USB Flash Drive (with password protected Disk Image) copies files very slowly. Why?

I'm backing up some data onto a 32GB flash drive that I've put a password-protected Disk Image onto, and am copying this data into, but it is achingly slow. It's taking hours to copy just 500MB!
I have another 64MB flash drive that I have set up the same way, but this one copies files very quickly. I can't spot any difference between them in Disk Utility/System profiler.
For the record, the process I've used for bothe drives is reformatted to Mac OS Extended (Journaled), then created a new Disk Image onto each drive (just a bitsmaller than the maximum size of the drive to enable it to fit) with 128--bit encryption.
Does anyone have any idea why the 32GB drive would perform any differently? I am using the same USB port on my iMac for each drive, but am getting very different copying speeds. It's driving me nuts! Many thanks.

The drive seems to be working fine if I copy files onto it outside of the Disk Image file (there's about 200MB of free space left over after I added the DMG). So I can only deduce from that that it is something specifically to do with the DMG itself. Though, as mentioned, I compared the DMG on my (fast) 64GB stick and the DMG on this problematic (slow) 32GB stick in Disk Utility/System Profiler (and I originally set them up in an identical way, as far as I am aware), and they seem to be the same. But one is performing achingly slow. Even dropping a file into the mounted DMG takes a few minutes to even think about it. It's very odd.

Time Machine encrypted disk image backup?

When Time Machine backs up my hard drive, it backs up a password-protected disk image as an open folder. Is there a way to back up the disk image without Time Machine opening it up?

I've played around with this a little. As best I can tell, when cloning an entire HD volume both CCC and SuperDuper will always copy an image file (.dmg, .sparsebundle, etc) that resides that on that HD, whether or not that file's disk image is mounted at the time. However the contents of the mounted disk image volume will not be copied separately, and so If the disk image is encrypted, no unencrypted content will get transferred this way. However as mentioned in the SuperDuper link above, it's better to unmount the image in any event, in order to ensure that the underlying .dmg or .sparsebundle file gets copied faithfully.
If you want to copy the contents of a mounted disk image with CCC or SuperDuper, you can do so as a completely separate procedure from copying the HD. If you first mount the image (giving a password if it was encrypted), that mounted image will appear as an independent volume in the "source list" of CCC or SuperDuper, and you can choose that volume as a source for the copy procedure. You would need to designate a different target volume as well, so as not to overwrite your HD clone. If the disk image was encrypted and you deliberately copy its mounted image separately in this fashion, the resulting files on the target will not be encrypted.

Merge Disk Image Shadow Files

I've fallen into the habit of mounting disk images with a shadow file to save disk space on my laptop. I'd like to merge the shadow file back into the disk image in order to better preserve the changes I've made. After reading the man page for hdiutil it appeared as if this task would be as simple as performing a "convert," specifying the image file and the "ov" flag in the options. However, I continue to receive "Resource Busy" errors despite the image being unmounted. Am I attempting the impossible, or have I simply missed the solution to my problem? Would anyone with any knowledge about hdiutil be able to share some insight?

I think you can not use the option '-ov' with the verb 'convert'; convert into a new disk image will work
hdiutil convert old.dmg -format xxx -o new.dmg -shadow shadowfile
After checking that new.dmg is OK, you may remove old.dmg. Or do you mean you don't have enough disk space to do this?
