Encrypted disk image from ****

So i made an encrypted disk image and forgot the password.
The disk image:
Size: 100 mb
Format: Mac OS X Extended (Journaled)
Encryption: 25-bit AES
Partition: Single partition-Apple partition map
..and no, i didnt save the password on my keychain
...(you can stop laughing now :P )
I´ve been in contact with Apple Care and we spent about 3 hours trying loads of things with no luck.
I know im more or less f*ed, but i know there is a lot of smart ppl on this forum.
If anyone has idea, no matter how crazy, im willing to try it.

Hi Worm76;
My suggestion is forget about what was in the encrypted disk image. Write it off as lost.
It would take someone like the NSA to get it back for you and I doubt very much that you have anything in there to interest them.

Can I recover an AES-128 encrypted disk image from the 'trash'?

I am a college student and I created an AES-128 encrypted disk image file (.dmg, .sparseimage) to store all my assignments and things. Unfortunately, while cleaning out my computer, I accidentally put the file in the trash without noticing and then proceeded to empty the trash. I then turned to the application 'MacKeeper' and used it's 'undelete' function but I could not find the file. It is very very important that I recover this file. I desperately need help.

You might have better luck with something stronger.....

Corrupted files within encrypted disk images

Greetings Apple Hivemind:
I've run across a repeatable problem when using encrypted disk images from Disk Utility. Essentially, I'll create an image using settings like are shown below:
The disk image is then used for storing data. In my case, this is usually data for Adobe Lightroom.
At first, this worked very well, and I housed the disk images on my household NAS, connecting via samba (smb) to it on my Mac. Over time, however, something odd started happening: Files on those encrypted images began getting corrupted whenever I tried writing new data to them.
My first incident was where Lightroom informed me that the catalog it was trying to open was corrupted. I tried to create a new one on the same encrypted volume, and it too was instantly flagged as corrupted. I opened the individual image files on the volume with no problem, so I wasn't thinking that the volume was the culprit. That is, until I tried dragging new image files to it manually. The new files were immediately either completely unreadable, or a mish-mash of the content of random OTHER files on the volume!
The result was that all old data seemed intact, but I could no longer write new data to the volumes without major data corruption issues. I thought that this was isolated to one volume in particular, but it soon started happening on ALL of my encrypted volumes eventually. Including those which were not, and never had been, housed on my NAS, but were on my local hard drives.
I've since "evacuated" all my data from these images, since the ones created by Disk Utility appear to be useless, and am seeking an alternative.
Is this something that anyone else has encountered when using encrypted disk images? It seems like this is something I should really open a support ticket for, but I can't say I've ever tried it, so I don't know how successful it would be to do so.

I should add that I've tried using the "Repair" and "Verify" functions of Disk Utility on the volumes, and despite the obvious issues that exist in them, the utility doesn't find (or fix) any inconsistencies.
Are you repairing/verifying the actual disk images, or just the partition they're on? If the partition, it won't look inside them.
Drag one to Disk Utility's sidebar, select it, then use Verify or Repair. Note: the usual messages may not appear on the DU window. Click the Log icon in the toolbar or select Window > Show Log from the menubar to see them.

Encrypted disk image on external drive prevents that drive from ejecting

I've tested this a few different ways, and it seems to be a rather consistent problem.
I have an external USB hard drive (seagate) and on that drive I use encrypted disk images to store my data.
(because it's a portable drive, I'm nervous I'll lose it and then someone will have access to my stuff).
So anyway, whenever I mount the sparse bundle disk image, when it comes time to eject the drive (after ejecting the disk image of course), it hangs for a while and then the Finder says it can't eject, but that I can Force Eject the drive. When I chose to Force Eject, it works, but I don't like having to force it every time.
Anyone know what's up?
Thanks,
Brian.,

Disk Utility create encrypted disk image hangs

I'm trying really, really hard to backup my data but apple is not making it easy for me.
I need my files encrypted for an offline backup. Time machine only allows home folder to be encrypted, and due to my home folder being on my SSD drive I cannot fit my files all in there, not by a long shot.
Using Disk Utility, I choose "new disk image from folder", and select "read only", 256-bit encryption. Some of the folders worked. However some will just hang for hours on "Creating Image, copying...". I can see at the destination the dmg file has stopped incrementing larger. It has reached the full size of the folder approximately. Does apple fail at some file types? I already ran disk repair several times to no avail. I don't know what else to try, it just doesn't want to work. All I want is an encrypted backup, that any OSX install can retrieve without any special software involved. Sometimes I'll get a very unhelpful error message "Operation not supported". Whatever that is supposed to mean. Google was no help so hoping for some insights here.

Create an encrypted sparse disk image instead of from folder, mount it, and then drag & drop your files into ii.

Unable to create an encrypted disk image with Disk Utility

Hi:
With our upgrade to Lion a few weeks ago, we're now unable to create an encrypted disk image of any type using Disk Utility any more. This problem occurs on 3 different machines, and is reproducible whether one is using an internal HD or an external FW HD. We can successfully create nonencrypted disk images.
This is a duplicate post with all the details here: https://discussions.apple.com/message/18469359#18469359
We haven't had any luck with a solution trying various permissions fixes as helpfully suggested by other readers in response to the error message # (-60008 error), so I'm hoping that someone else has run across a solution from the encrypted disk image perspective and that this tag line will generate some help.
Thank you!

All works fine
Then I repeated this using:

Create encrypted disk image with OS install disk utility.

I thought to make a full backup of Macintosh HD, and followed instructions in /kb/ht1553. However, every time I tried to creae an encrypted disk image, it barfed with "Failed - User interaction required". I assume it needed the encryption password, but for some reason was unable to display a prompt for this. Anyone know how to fix this? Thanks, Stephen.

Disk Utility - Create encrypted disk images super sloooow

Trying to create encrypted disk images via Disk Utility on my iMac (i7 8GB) is super-slow in 10.8. It worked quite fast in 10.7, but now it's super-slow and doesn't even seem to ever finish.
I've tried re-installing 10.8 with no difference.
Anyone else having trouble with this? Even a small dmg (~200MB) doesn't seem to work.
Unencrypted images seem to work OK (if not a little slow).
I realize that the encryption process will be slower but something is definately wrong with 10.8 disk utility in this regard. I have 1TB+ free space. I have tried with another user account as well.
My task was: (new disk image, read-write, 128bit encryption)

2012-09-03 09:00:00 -0400: Creating…
2012-09-03 09:03:28 -0400: Copying… <<< seems to be stuck here...

Good morning,
Have you tried using Disk Utility from within the recovery mode? (Hold down CMD and R when booting)
I used to have this problem but creating them this way really improved the time.
Give it a go...

Creating an Encrypted Disk Image on an External (USB) Drive

I have an external 600 GB drive (2x 300 GB SATA 3.5" disks in a Thecus N2050 RAID0 external enclosure connected to iMac by USB2) onto which I would like to backup a large amount of data (500 GB).
I store this external drive away from my home (in the office) and since I cannot guarantee physically locking away the drive I would like to logically lock the drive by placing all the backup data into an encrypted disk image created on that volume.
I have tried creating an encrypted disk image on my USB volume in Disk Utility (Apple's instructions here) but I experience a number of issues not documented in the Apple article:
1) I am not presented with a drop-down option for the size of the disk image.
2) When I go ahead and try to creat the image I am told that the creation was impossible "file or folder does not exist".
Is it possible to create disk images on USB volumes (I cannot create such a large disk image on my iMac HDD as I do not have sufficient space).
thanks in advance
Raf

I realised that in Disk Utility you must not have any of your mounted drives highlighted in the left hand pane.

Indexing of encrypted disk images permanently disabled in 10.8?

In the past, I've had no trouble forcing Spotlight to index my encrypted disk image, using the command in Terminal:
sudo mdutil -i on /Volumes/Encrypted_Data
After entering that command, my encrypted disk image was indexed and searchable using Spotlight.
A couple weeks ago I updated from Lion to Mountain Lion. Today I noticed Spotlight wasn't showing any results from my encrypted disk image. So went back to Terminal and entered the above command. Instead of successfully activating indexing, Terminal gives me this message:
/Volumes/Encrypted_Data:
Indexing disabled.
Is this procedure now impossible in Mountain Lion?
Is there any way to enable indexing of this encrypted disk image? I can't get it to work.
Thanks.

I appear to have solved the problem to get Spotlight to index a disk image. My image was an encrypted disk image. I was able to get spotlight to work when it was new, but now Spotlight won't index it. Here is the solution that I found:
After double clicking and mounting disk the image, open Disk Utility, select the disk image file, then click unmount in the Toolbar. Wait until it is unmounted, then click mount again. Then go to terminal and try mdutil -sa . If it is still not enabled, try to sudo mdutil -i on option. The unmounting and remounting must be done everytime the image is opened.

HT1578 Labels (Mavericks) not working in encrypted disk image?

I created an encrypted disk image with Disk Utility.
I placed a file in the opened encrypted disk image, and labeled it with "test".
If I open a finder window and look for files labelled "test" the file doesn't appear.
This message is placed under the wrong OS, because it is not possible to choose Mevericks from the popup list!!!!

Encrypted Disk Image Won't Partition After Resize

Hi,
I have a 10 GB encrypted disk image on my macbook (type OS Extended (journaled)). I've pretty much filled up the space so I want to resize. I go into disk utility with the disk unmounted and 'Resized' it to 20GB. Then I mount it and go into the Partition tab. I drag the corner all the way down to fill up the space and hit Apply. It goes through the motions without error but it does not actually extend the partition to the resize. On the right next it then says something to the effect that the disk is read only and cannot resize the partition. The write status is read/write until I click apple....then it switches to 'Unmounted, read-only'. Any ideas on how to fix this? It's driving me crazy. I can provide screenshots when I'm home from work if necessary.
Thanks
Nick

Here are some screenshots of before and after I try to partition (after the resize):
After attempting to resize the partition it says 'The disk is not writable and can't be partitioned' and 'The disk is too small to contain partitions'. The disk write status also changed to read only. Doesn't make sense to me...anyone know how to fix this?
Thanks

Encrypted Disk Image - Eject on Sleep?

Is it possible to setup my computer so that an "open" password-protected Encrypted Disk Image will automatically eject itself on shutdown, sleep or logout. If so,how?

Disk image files are dismounted when the computer shuts down or restarts. In the "Security" system preference, you can set the computer to require a password to wake from sleep or screensaver.

Encrypted disk image on a network, is the data encrypted during reading/writing?

I'd like to use an encrypted image for storage of sensitive data on an openly accessible network storage. Does anyone know if the data that is written/read from the image (once it is mounted) is transferred over the network in an encrypted or decrypted form?
It's seems important, since if the network connection is not encrypted then the data might be accessible to others.

Efren,
When you mount an encrypted disk image, the machine you are using (and on which the image is being mounted) is handling all encryption/decryption. So yes, the data that is transmitted across the network is already encrypted.

Encrypted disk image sometimes mounts without password

I have an encrypted sparsebundle disk image containing sensitive information. On occasion (maybe one time out of ten), I'm able to mount it without being prompted for the password.
The password for the image is not stored in my keychain. Can anyone offer advice on this issue?

I was having exactly this same problem!
I keep a small encrypted disk image storing sensitive banking information. I do NOT have the option to store passwords in Keychain checked, and I verified that the password is not being stored in Keychain.
Yet, when I double-clicked the supposedly encrypted sparsebundle disk image, it opened right up and mounted - no password required! Unbelievable, right? So I started to investigate.
I first noticed this behaviour in Mountain Lion, I'm running 10.8.4 on a 2.7 GHz 15" MBPr.
In past versions of OS X I would mount the volume to work on it by double-clicking on the disk image, enter my passowrd, and then Eject the volume either by dragging to the trash or clicking the Eject button on the Sidebar. The next time I would try to access the disk image by double-clicking it, it would again prompt for a password. All good.
What seems to be happening in ML is, using the same workflow, even though the volume is disappearing from Finder, the disk image is not actually being unmounted!
When I go to Disk Utility, the disk image is still mounted, but the volume is grayed out. When I Eject the disk image in Disk Utility, it then reverts to the expected bahaviour, and double-clicking on the disk prompts for a password.
So the workaround seems to be when finished working on the volume, go to Disk Utility and manually Eject the disk image (as opposed to just the volume it mounts) to ensure it has unmounted and is thus again encrypted. The reason for it sometimes requiring a password, sometimes not is probably because after a restart of the computer it would unmount all disks, and then be unable to re-mount it until the password is entered. But in between, unless you were aware of this behaviour anyone with access to the disk image can view its contents.
What a terrible security flaw IMO, as there is no visual indication in Finder that the disk image is still unprotected after you unmount its volume and that icon disappears! I'm surprised this hasn't gotten more attention.
Incidentally brian_c, I tried to look at your linked videos but it returns the message that the videos violated the TOS of the site...?
