Alias to open a file in an encrypted disk image

Deleted.

There is a quick and simple test, could someone with Lion installed be so kind as to do this:
1. Use Disk Utility (or Knox if they own the app) to create an encrypted disk image on the Desktop called Test
2. Mount the image, open TextEdit and paste a page of text into the window, then save the file in the mounted disk image
3. Paste another page of text into the TextEdit window
Open Terminal, navigate to /Volumes/Test, view the hidden files in the directory & post the results here.
All you need to do to clean up is eject the disk image then drag the .sparsebundle file to the Trash.
Cheers

How does one save new files to an encrypted disk image?

I encrypted a particular folder, and used a sparse image to leave plenty of room, as well as using read/write permissions, but I don't see how to save new files to the encrypted folder.

So, I guess you have to save the file to the desktop and then drag it to the mounted disk?
No, you should be able to save directly to a mounted disk image via a dialogue box. There is no need for an intermediate step. As long as the encrypted disk image is mounted, it is open and appears to be just another folder.
As an experiment, open a Textedit document and save it to the mounted (open) disk image via Save As in Textedit. It should be able to do that.

My Automator script to backup files to encrypted disk image

Hi there. I have a question regarding Automator and Encrypted disk images. I've put together a workflow that grabs files in my home folder. My home folder is utilizing FileVault. I'm grabbing things like my iphoto library, documents folder and such. On an external usb drive I've created an encrypted disk image about 100GB. My goal is for the automator action to "successfully" mount > copy > unmount the encrypted image.
As of right now, the script works, but gives an error at the end of the copy, not allowing a successful unmount of the dmg. Is there something I'm doing wrong? I browsed through all the files after copying and they are all there, the folder sizes match up 100%.
I guess I could just use a program that does this, but, I find it much easier clicking on a shortcut in my dock to run the script and go away for 10 - 15 mins.
If it would help to view the script, let me know and we'll work something out.
Thanks

The popup box says:
The action "Copy Finder Items" encountered an error. Check the action's properties and try running the workflow again.
And the Automator workflow log says:
Can't read directory contents: /Volumes/Backup
But as I said, clearly it works and reads/writes to the encrypted dmg because all the files are there. What I do is just select all the folders inside the drive first, and delete/empty the trash first before running the action. This is the second step once I know this is working. So that I don't have to manually delete them everytime before running the script.
So to answer your question, the drive is empty, and the dmg is empty, allowable for a maximum 100GB of storage.
I think it might be something to do with copying files to an encrypted disk image, but, I can't find any help anywhere on this.
Thanks

Lost password for encrypted disk image

i created a encrypted disk image to store some personal files and now i can not remember my password and its not in my key chain is there a way to reset the password or at least recover the files.

If you could access the files on an encrypted disk image without knowing the password, there wouldn't be much point in encrypting it.
Do you remember anything at all about the password? Was it a name, or a dictionary word? If so, there might be hope of cracking it before the Earth passes away. You'd need the help of a consultant to do that.

Removing an encrypted disk image

A while ago, I created a 7gb encrypted read/write disk image and put some files in it. Now, recently, I removed the files in the encrypted disk image and copied them back into the regular HD. I erased the mounted disk image and now says it's back to 7gb.
How do I remove the disk image? It's still there in my documents folder. How do I melt it back into the HD space? I can remove it from the side bar on the disk utility page but it's still on my HD and I can still mount it to the finder. I enter my password and it mounts.
I want to get rid of that disk partition as I don't use it anymore. What do I do? Is it there forever and am I stuck with it?
Thanks in advance for anybody that can help me with this.

Niel,
You know I actually tried that before but the trash was hanging and hanging. I have it set to empty securely and I know it takes longer for secure empty but it was really long.
I'll try it again but is that normal? Does the encryption have anything to do with it?
Thanks for the help, hope this time it works.

Encrypted Disk Image Seems Full But Is Not 10.5.6

I've created a 20 gig encrypted Read/Write disk image (not a sparse image) using Disk Utility. The image resides on an external hard drive. I back up a 900 mb file each day to the encrypted disk image. There are six such files on the encrypted disk image, but the folder shows only 526 MB of free space left. Does someone know why this is happening and how to avoid it? (It happens as well when I back up the same file to an encrypted disk on a flash drive. I delete and replace the file and this process seems to eat up space on the disk image.) Thanks.

when you delete a file you have to empty trash while the disk image is mounted. that should free up the space on the image. I would also recommend using sparse image instead of a regular one. it will take less space on the hard drive and you can make it bigger if you have to.

Encrypted Disk Images on iOS devices

Is there any way or application to access the contents of an encrypted Disk image file created using Disk utility on an iOS device like an iPad or iPhone. This is one of the real limitations I am facing in replacing my MBA with my iPad. I store my sensitive financial files in an encrypted disk image file synced via my Dropbox folder across all my devices, which I am not able to access from my iPad. Does anyone know of a way or workaround?

You might look for an app for that. I think I remember seeing a couple. Or you can set a passcode for accessing the machine. When you attempt to turn the machine on there's an immediate or delayed request to enter the passcode - a 4-digit number. Without the passcode your iPad is unusable. Only you can turn off the passcode. You can also enable the need for the passcode to access certain apps. This is set in the restrictions.
All this is accessible through Settings/General. As of now there's no way to put disc images files onto an iPad and access them.

Adding files to encrypted disk images

Here's what I'd like to do:
- Select a file or folder "foo" with Finder
- Go to my AppleScript menu bar item and choose a script to do the following:
1) Mount an encrypted disk image (I already have one made); the password is not in my keychain so I'll need to be prompted to enter it
2) Copy "foo" to the top level of the mounted disk image
3) Unmount the disk image
4) Move the original file to the trash
5) Secure empty the trash
I don't speak AppleScript very well; can anyone help?

Thanks, Niel. You are always so helpful.
I couldn't get it to work, though. The disk image wouldn't mount with the "open file" command. So I changed the first line to:
do shell script "hdiutil mount ~/Documents/Miscellaneous/files.sparsebundle"
That works; it prompts me for the image password and then mounts the image. So far so good.
But then it stops with this error message:
Can’t make {} into type alias.
Do you know how to fix it?

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.

I'VE CREATED A FORM WITH IMAGES. WHEN I OPEN THE FILE IN ACROBAT READER THE IMAGES ARE BLACK BOXES.
THE FORM HAs (extend features to acrobat reader). THE FORM WAS DISTRIBUTED.
NON OF MY EMPOYEES CAN SEE THE IMAGES. WHAT'S WRONG? CAN YOU HELP?

However, the view large images is an issue for a form that is being distributed. Either a note needs to be added to the PDF to tell how to enable the view or the images need to be changed so that the enabling is not needed.

File Vault on HOme Directory with encrypted disk image in it

I want to try File Vault. My question is as follows: I have an encrypted disk image already in my home folder. It is a small 500 MB one. Can I keep that in there, as is, without problems, or is File Vault going to encrypt and encrypted image and cause some sort of problem?
Has anyone done this without issues?
I know the alternative is to unencrypt my current image and let File Vault handle the encryption, but I am curious about leaving it alone and trying File Vault.
Thanks for any help,
x-.-x

Good luck!

FileVault is no more likely to scramble an encrypted disk image than it is to scramble the rest of your files. However, it is quite likely that it will scramble all of your files.
Has anyone done this without issues?
I have read many postings here in the discussion forums by people who have used FileVault and lost all of their data. Your mileage may vary. The only way I would use FileVault would be if I had an unencrypted copy of everything somewhere safe. Like you, I keep a small encrypted disk image for particularly sensitive files.

Encrypted Disk Image - Can't find it

I just created a 1GB encrypted disk image using the Disk Utility program on my macbook (Macintosh HD). After I created it, I put some files in it. Then I "ejected" it, logged off, and then logged back on. It is no longer on my desktop. I tried doing a search and still can't find it.
So...how did I find it and how do I create a short cut so I don't run into this again?
Regards,
New Apple User

To expand a little on Steve Sherriff1's answer: when you created the encrypted disk image in Disk Utility, it created a file with a .dmg extension, saving it wherever you specified (if you open Disk Utility and again select 'New -> Blank Disk Image' from the File menu, it should still be pointing to the last location you save to). That .dmg (disk image) file is opened as a virtual disk on the desktop when first created. When you eject it, it won't automatically reappear on the desktop; you need to find the .dmg file (using Steve's tip) and double-click the .dmg to mount the disk image. For easier mounting, you can put an alias to the .dmg file on the Desktop, in the Dock, or in the lower-left pane of your Home folder.

Unable to create an encrypted disk image in Lion

disk utility gives the error Unable to create "Volume.dmg." (error - 60008) when creating an encrypted disk image. I am using the following steps:
    1.    Open disk utility
    2.    Select the disk (internal or external) to create the image on
    3.    Select File>New>Blank Disk Image…
    4.    Save As: 'Volume'
    5.    Name: Volume
    6.    Size: 50GB
    7.    Format: Mac OS Extended (Journaled)
    8.    Encryption: 128-bit AES encryption
    9.    Image Format: read/write disk image
    10.    Click the Create button
    11.    Password dialog appears
    12.    When I enter a password the dialog closes after entering only a few characters i.e. before I've finished typing, and the following error message displays:
Unable to create "Volume.dmg." (error - 60008)
I have previously, successfully, created encrypted disk images in Snow Leopard, and I don't know why I can't in Lion
Does anyone have any ideas?

Thanks for this Thomas.
I've tried naming the image differently, but still received the error, I did however try different permutations for the password.
The error seems to happen if I use a purely numerical password string and occurs on input of the 10th numerical character, if I start with numerical character but use an alpha before the 9th number I can continue and create a password, and I can create a password if I start with an alpha and switch to numerals after the first alpha character, purely alphabetical passwords are fine too.
It seems that Lion doesn't like purely numerical passwords greater than 9 characters, whereas Snow Leopard wasn't so fussy. Seems it's a bit of a bug.
Thanks for your help

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.,

Open Disk Utility > File > New >Blank Disk Image...
or use the "Option-⌘-N" Key combo (with Disk Utlity open).

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.
