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...

Can't create encrypted disk image

With Leopard, I have repeatedly followed the instructions for using Disk Utility to make an encrypted disk. All appears to go well...all fields appropriately filled, including 128 encryption. But when I hit create, either nothing happens, or I get a second Disk Utility starting window. In any case, I am not asked to create a password, and am unable to find any trace of the disk I thought I'd just created. Would welcome your thoughts.

While creating, make sure that it's saved to the desktop so you will know where it is supposed to be, at least.. Was wondering if posssibly you lost them. Look for the named disks in your home folder and in HD on chance they are there somewhere.
I know you went to Help but just making sure you are creating disks this way (below). Everything worked fine for me--
If things still don't work, turn off DU and move to the desktop "com.apple.DiskUtility.plist" in your home folder/library/preferences. A new file will be created when disk utility is turned on again. Deleting plist files don't usually don't solve problems but sometimes they can become corrupted.
Good luck

1 choose File > New > Blank Disk Image.
2 Type a name for the image, and choose where you want to save it.
3 In the Volume Name field, type a name for the volume that appears when you open the disk image.
4 Choose the size of the disk image from the Size pop-up menu.
5 Be sure you choose a size that’s large enough to hold any changes and new documents you might add.
6 Choose an encryption option from the Encryption pop-up menu.
7 Use the default settings for the rest of the options:
8 Choose “Mac OS Extended (Journaled)” from the Volume Format pop-up menu.
9 Choose “Single partition - Apple Partition Map” from the Partitions pop-up menu.
10 Choose “read/write disk image” from the Format pop-up menu.
11 Click Save.
Enter a password, and click OK.
Disk Utility creates the disk image and mounts its volume on your desktop.
Copy the documents you want to protect to the volume.
If you want to erase the original documents so they can’t be recovered, drag them to the Trash and choose Finder > Secure Empty Trash.

Problem creating encrypted disk image

I have just moved from an Aluminium PB G4 with 10.3.9, on which I successfully created encrypted disk images and sparse images.
I now want to do the same on a brand new WD My Book attached to the new Macbook Pro. I open Disk Utility and click New Image. But when I do so, there are fewer options than there are on the old machine. I only have
Save As
Where
Image Format
Encryption
No option for specifying size, no sparse option.
Also, if I try and create a dmg on the My Book, I get 'Unable to create "myfilename.dmg". (Invalid argument)'
Any suggestions? Thanks

V.K.'s suggestion worked. Thank you. But now I've found that I get the full set of options in Disk Utility too. Baffled.
In the week I've been using my new Macbook Pro, I seem to be getting eerily similar experiences, i.e. apps don't work right, then I quit and next time they behave themselves. Yes, I know it sounds weird.
Is this an appropriate place for me to ask further questions. Namely, what's the best place to find out about 1. read/write v. sparse disk v. sparse bundle? 2. partitions - should I used them, whatever they are? and 3. why are the bigger disk images called CDs and DVDs? If I want a passworded place to put files on my external drive, bigger than 500MB, is there any reason not to use one of the CD/DVD size options?
Thanks

What is the proper way to create a monotone image with real looking contrast?

Once I apply a color to my previously created black and white image everything looks washed out.
I have an artwork with 3D representation of the letterforms, casting shadows on the textured surface. Shadows are deep black. I need this artwork to be colored in gold. My client forwarded me the specs for the metallic gold which he got from the PANTONE. They are:Gold (871); Adobe 1998 RGB: 126-113-76
HSB*: 44 degrees-40%-50%
What is the proper way of applying those values to the desired image.
My idea was to make the image black and white and than create a monotone image with the above specs. In this case the image gets washed out as the darkest black in the shadows becomes this Pantone gold. Is there any other way?

A duotone will work, however you are going to want to work closely with your printer . Most printers will want the second color in CMYK (Possibly C60 M40 Y0 K100 instead of RGB values or specify a Pantone Rich Black (I personally like 6C)but it will cost you more for the wash up of both heads of the printer...
Go to Image>Mode>Duotone (image must be greyscale first for this to work) then add the desired colors to your ink scales.

Can I create a rotating image with sevaral images in Photoshop?

I was wondering if I can create a rotating image with sevaral images in Photoshop? Much like a gif? Would this improve my page load time or would it be the same as loading a slideshow? Here is an example of what we wanna do vacationsalabama

Yes you can create a gif in PS to do this but it would be much easier to accomplish with some simple JQuery Image slider.
Several examples here
and here
The benefit is they load faster, have speed options, and switching images out is a breeze. They can also have links asigned to the images as they appear.

Trying To Create Encrypted Disk Images With Disk Utility.

I am trying to create encrypted read and write Disk Images of around 2 GB to 6 GB with Disk Utility.
More often than not the dmg is NOT encrypted.
It seems very hit and miss . . . . most of the time missing!
Is this process notoriously unreliable or am I likely to be doing something wrong?

I think you have cracked it Niel!
I made another, unchecking the Keychain box, and it worked perfectly.
I have been using a password which is used for other items.
Now the .dmg has been created can I check the Keychain box and if so what are the benefits?
I have never understood what the Keychain does.

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.

Disk Utility fails to create encrypted disk image

When creating a disk image using 256 bit encryption and a purely numeric password longer than 13 characters the following message appears:
Unable to create "ABC.dmg." (error -60008)
the error happens upon typing the 14th consecutive number into the Password field. I have created images under the same conditions in the past, Not sure if this is caused by Lion.

Looks like one of the drives is bad.
While it passed being zeored with Disk Utility, it failed about 15 minutes into a 'Certify' using SoftRAID.
Now waiting on a replacement drive from Newegg.

How to create encrypted disk image?

In Disk Utility, I select to create a new image that is password protected. I'm prompted to save and give the image a password. It never ask for the size and starts "Reading whole disk". I don't want to encrypt my entire disk. This image might only be 5MB.
What steps do I take to create a DMG that is about 5MB and password protected?

Rename it in the Finder as you would any other item. If needed, choose Get Info from the File menu when the mounted image is selected in the sidebar.

Copy of a CD (created by Disk Utility) not recognized by Windows or Linux

I created a copy of AutoCAD 2005 (not pirating it... just wanted a backup copy of the install CD).
I used Disk Utility (File > New > Disk Image From Folder) to successfully create a DMG file on my MacBook. I could mount the DMG and browse all the files on it.
I then burned a CD (Disk Utility > select DMG > click burn), which mounts fine on OSX. However, my Windows and Linux boxes will not recognize it (while they recognize the original CD just fine).
I tried again, this time setting the file format to DVD/CD master. It made a CDR file, which I burned to CD. Got the same result: Windows and Linux don't recognize it while OSX does.
So instead I burned the files to a CD ala drag and drop using Finder. This time the CD was recognized by Windows and I used it to install AutoCAD.
However, my understanding is that doing it this way won't work for a bootable CD, so I'd like to figure out why Disk Utility wasn't able to make an exact copy.
Any thoughts? Problem with copy protection? Problem with the CD's file system?
Details about the optical drive in my MacBook (1st gen 2.0GHz, 2GB RAM):
MATSHITA DVD-R UJ-857:
Firmware Revision: HBE4
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB

DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: No
MacBook 1st gen CoreDuo 2.0GHz, 2GB RAM Mac OS X (10.4.8)

Yeah OS X's Disk Utility doesn't burn using the ISO 9660 file system while Finder does (I could swear I made a copy of an MS Office CD with Disk Utility, but maybe I'm remembering wrong). Anyway, Disco (a program I got in a MacHeist bundle) will make an exact copy of CDs. Anyone looking for a free solution, check out LiquidCD and burn, which may have the ability to copy Windows CDs (appears to be on their lists of features, but I haven't tried them myself).

Cannot Create Encrypted Disc Image

So, I can't seem to create an encrypted disc image in Disk Utility, as the linked screen capture shows:
http://imgur.com/7dv3t.png
The "Create" button is grayed out. This occurs even if I try different settings for Volume Format, Partition, Encryption, and Image Format.
Anyone have any ideas on why this is happens?
(Running 10.5.8 on a MBP Santa Rosa, with no modifications except for 4GB of RAM, and I wasn't able to create disc images even before the 10.5.8 update.)

No problem. I remember being stumped by the exact same thing myself.

Can;t read a .dmg created by disk utility

I am looking for help to get a restore from a .dmg from an external usb drive and restore to my macbook. The backup was taken from disk utility running on Snow Leopard.
Over the weekend I needed to update my macbook and install windows using the bootdisk application. I ran bootdisk and got an error telling me there was a problem with the partitions and instructing me to take a backup; fix the partition and then restore. Foolishly I took a disk image copy and not time machine.
Having fixed the disk I went to restore the image from the drive but got a message saying it could be restore as an “imagescan” has not been performed. I ran the scan image for restore from the disk utility and got a message that states unable to scan (broken pipe).
When I try and mount the image I get a I/O error and it will not open. If I run First aid on the image it say it is fixed!!!
Doe anyone know how to overcome this error? Is there a tool I can use to fix the images??

You could try the tips found here:
http://www.macosxhints.com/article.php?story=20070419082314524
And in the future, don't trust your files to one single backup, much less a backup on a disk image file. When you erased the hard drive, the backup became the original, but any slight bit of corruption in a disk image can destroy the whole thing, making this a very risky thing. You should always have *at least two* backups!

Does Time Machine utilize the password I created in Disk Utility?

Using Disk Utility, I created a volume (confidential.dmg) which contains personal information. Within Disk Utility, I also elected to require a password to open this volume.
Using Time Machine, I back-up the entire contents of my Mac to a fire wire drive.
If someone had possession of my fire wire drive, would they have to know the password I created in order to open confidential.dmg? Or are there other ways someone else could access the contents of confidential.dmg?
Thanks

Time Machine will just back up the encrypted disk image so yes, if somebody had access to your Time Machine they'd still need to know the password if they wanted to open it.
