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.

Even though I have LCD font smoothing disabled, Mountain Lion still uses it in PDF views, Safari's location bar, Mail's message view, and the dialogs for mounting encrypted disk images.

Even though I have LCD font smoothing disabled, Mountain Lion still uses it in PDF views, Safari’s location bar, Mail’s message view, and the dialogs for mounting encrypted disk images. Is there any solution to this problem? Also diabled the Smoothing in the SystemPrefs and also via Terminal. Font smoothing is still there. Very annoying, especially in PDF attachments in Apple Mail.

Try feeding Safari a user-defined CSS file with font-smoothing tweaks (including none). The filename and its filesystem location are arbitrary. Use your favorite coding editor.

Any gotchas for encrypted disk images?

I am about to set up e-bills and e-statements at various banks and credit cards and wanted to check a couple of things before doing something that may end up being bad
The assumption I am going with, is I will create an encrypted disk image to store all the PDF's.
1. Is that the right thing to do? Or is there a better way to keep the data secure?
2. If I do so, what is the backup impact? Can I simply set up a task to copy and paste the entire disk image to my external drive?
3. If I want to open the disk image on another computer, can I? How will it authenticate the user/pass on a different computer?
4. I can backup an encrypted disk image to a FAT-formatted external drive?
5. And finally, I have read disclaimers that if I forget the password the data is lost irretrievably. But also, that the password is stored in keychain. So if the password is stored in keychain, the worst-case scenario can only happen if I forget the master password, right? I don't need to truly remember the password to the disk image necessarily, right?

IIRC, encrypted disk image passwords are independent from Keychain Access. So if you forget it, then you're hosed. BTW, that's the major failing with encrypted anything. If you forget the password, you're hosed. If the disk image gets corrupted, it's useless with or without the password. Anything stored in an encrypted disk image needs to be backed up in an unencrypted state and stored in some kind of physical thing like a safe. Methinks your a bit paranoid. Disable auto-login, use high-level passwords (that you remember), don't enable the root user account or activate a master password, and you should be secured enough.
I updated the profile. I am running Leopard. So this is the correct forum.
What am I trying to protect? I thought I put it in the first line - statements from banks and credit cards.
From whom? From unwanted entities who may get access to my computer, in any way.
I didn't get the part about the safe. Can I or can I not back up an encrypted disk image to an external drive "as is"? What about possibly opening it up on another computer? And how about putting it on a FAT-formatted disk? I repeat my original questions, but for a reason - they seem to have not been answered.
I do not have auto-login, and I remember my strong login password. I don't have my root account enabled. Under this scenario you think my data is going to be secure? What about if someone were to get control of my computer? Forgive me on this one, I am a switcher so there is a general paranoia about such things which I would like to clarify before reorganizing my life.

Encrypting Disk Images

Hi,
I've followed several guides to create an encrypted disk image so i can hide some private files on my Mac - All the guides said the same way and one was the one here on Apples site and still i have no luck.
I create the disk image and when i put the files in it, eject the disk and try to mount the disk again from the DMG file it doesn't ask for a password. The only solution i can see is that it is because this does not work as i am admin and trying to password a file in my on account? Does this only work for shared folders with other users or is there another explanation as to why this won't work?
Thanks

Well Keychain is really there for your convenience. It remembers your passwords so that you don't have to enter them when they are needed but it is sort of a security risk of you just leave your mac sitting there and your keychain unlocked. However, these passwords can only be used while the keychain is unlocked. An admin password is needed to actually view the password.
You can lock an unlock the keychain manually or have it lock automatically after a certain amount of time (in keychain access go to Edit -> Change settings for keychain "login") or when your mac sleeps. But you might want to consider the security of your mac as a whole instead of just the keychain. For example: is it easier to keep the keychain locked or is it easier to prevent access to your computer as a whole (like disabling automatic login and requiring a password from waking from sleep?).

Writing to Encrypted Disk Image SLOW On Mac Pro

I have a slew of Previous Gen (2010/2012) Mac Pro 12-Core 2.66 desktops running 10.8.5 (12F45). When making a standard 128-bit Encrypted Disk Image, the write speed to that image is extremely slow. Disk image is on the same system internal drive as the source material. Also tried on Gigabit Ethernet share. 1GB file takes 20 minutes.
If I take the same disk image and run it on a 2012 Mac mini server 2.6 i7 running 10.8.5 (12F45), the write speed is fast; 1GB takes 1 minute. Same holds true for a MacBook Pro (non-Retina) 2.3 i7 running 10.8.5 (12F45).
Antivirus is disabled on all machines for testing purposes. Mac mini is actually a clone of the Mac Pro's system, so everything is the same, software-wise.
Is there something inherently wrong with these Xeon Mac Pros that they cannot write fast to encrypted disks? Any other variables I'm not thinking of?
Thanks in advance.

The write speed to an encrypted image is around 5.65MB/s in comparison to 92MB/s on normal disk. I feel frustrated to see the remaining time to copy 800GB of data from internal HDD to the mounted encrypted volume takes around 1 day. An encrypted disk managed by Truecrypt on any PC will work much better than it.

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

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!

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.,

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.

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

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 08:59:59 -0400: Initializing…
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.

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.

bbonn wrote:
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.

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!!!!

Time Machine Backups of Encrypted Disk Images, Part 2

Hi:
If Time Machine is backing up a hard drive that contains a subset encrypted disk image as part of its contents, and this encrypted disk image is mounted (in an unencrypted state) where the enclosed data has been changed/manipulated in any fashion, what and when does Time Machine backup?
In other words, does the data in the encrypted disk image only change when the encrypted disk image is unmounted? Or is it somehow backed up real time even when the encrypted disk image is mounted on the desktop in an unencrypted state while Time Machine is working?
Sorry I can't explain this very well, but hopefully the gist is clear.
Thanks!
(OS 10.8.2)

Time Machine doesn't back up a disk image file while it's mounted, whether encrypted or not.

Encrypted Disk Image

Is there any way to have an encrypted disk image warn other users, upon mounting, that it has already been opened or is currently open by someone else? If not, then anything comparable?
This whole situation arose based upon the need of having a password protected folder on the network. Someone then chose as a solution to have an encrypted disk image.
Wouldn't several people mounting and writing to such an image simultaneously cause corruption?
Any workarounds?

Hi flimps,
A couple of things...
1. How did you create the disk image? Did you do it through Disk Utility or a 3rd party program?
2. Are you checking the box "remember this password in my keychain" when you're creating the password or authenticating? If so, your keychain will automatically store that information and "auto fill" each time you want to access the image.
