Ecrypted disk image

Is it not possible to create a password protected encrypted disk image in OS 10.3.9 Panther? I am able to create and encrypt a disk with password well enough, but when testing, the disk opens without prompting for a password.

Hi
This is because you have failed to deselect 'Remember this password" when you first opened it. The password is remembered in your keychain.
Either open Keychain Access and locate the password key and delete it, or make a new encrypted Disk Image and choose not to have it remember the password first time you open it.

Problems with ecrypted disk image

I'm trying to restore my laptop (Titanium DVI) from an encrypted disk image, and am having no luck. I have my laptop in target disk mode hooked up to a Mac Pro with the backup disk image.
When I use Disk Utility and attempt a restore, it prompts me for the disk image password, and it starts copying (and apparently succeeds in copying some items). But then after only a few seconds, it prompts me for the disk image password again, and I enter it again, and then I get an error 2, no such file or directory and it dies. After this subsequent attempts without rebooting result in error 16, Resource busy. Finder shows no disks mounted, but a ls of /Volumes shows that there are in fact copies mounted there. unmounting them from the command line does not clear the resource busy problem, but rebooting does.
I thought maybe the encryption is confusing things -- support for this seems sketchy. There seems to be no provision with command-line asr to deal with encrypted disk images. Also, hdiutil can do some things, but for instance I can't use convert to read the old disk image and create a new one, because it tries to apply the -stdinpass option to the new image, not the old one. I'd like to try making an unencrypted image to see if that is causing the problem.
edited to add that I'm doing an erase restore.

You choice. Since the immediate problem's was solved, you might want to start a new thread on the diskutil issue in the Unix forum: http://discussions.apple.com/forum.jspa?forumID=735 and start a new one in the Using Mac OS X Tiger forum on any Disk Utility issues.

Authentication error when I try to make encrypted disk image

I usually make an ecrypted disk image when I back up my financial files on my Powerbook g4 or flashdrive. Just recently I get a "cannot make" "files" - "authentication error". I've tried the single user mode and removed files as per the discussion boards to no avail. I've tried also to reset my password from the OSX disk. Any suggestions. Thanks

Delete encrypted disk image - how to ?

Folks,
I need to delete an ecrypted disk image I created some time ago. I frankly don't know what is in there and have not checked it in some time. Furthermore, I have forgotten the password, which I must have changed - because the one that is in my keychain does not open it.
So how best to do this ? I am reluctant to just drag it into the trash. In addition it is 40 meg I would like to get back. Can anyone help ?
Thanks

Just trash the disk image file (.dmg).

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.

Disk Utility doesn't finish creating new disk image - naming issue??

Recently I upgraded to Snow Leopard and carried along an empty disk image created in OS 10.4.11. I use these for archiving data on read-only DVDs and password protect the images.
In the earlier OS, I found the practical limit for the dmg was 4.3 GB, containing 4.27+ GB of data (anything larger failed when attempting to burn data DVDs). Today, when I looked at my empty dmg file, the OS 10.6.6 Finder showed it to be larger both inside and outside (just under 4.7 GB inside I think - didn't write it down). I suspected that it may be corrupted or at least not give correct directory information, so I deleted this dmg as a precaution and tried to make a new one with the old size by selecting custom size within Disk Utility. Now every time I try to create a new dmg this it stalls at about 100 MB.
The image format panel has several additional settings in OS 10.6 . There are two places for names - in the "Save as" field above and in the "Name" field below. (Haven't yet found any documentation where the reason for this is explained or which lists possible name limitations. The Help info appears to be identical to what was in 10.4) I've tried making both names the same, but it still stalls
Disk Utility settings:
Save as __Diskname
Name in lower field __Diskname (have also left it blank no difference)
Custom 4.3 GB
Mac OS Extended (journaled)
128 bit encryption
single partition
read/write format* (also tried CD/DVD master - no difference)
* All files are not necessarily added at once so I'm pretty sure I want this to be read/write

In case this isn't obvious I mean read/write formatting on the hard drive, but when burned the format will remain the same whether or not the disk used is rewritable

Hi Michael,
Did you reformat it HFS+ or something else?
Some USB2 Flash Drives Write at a disappointing USB1 speed, but Read at USB2 speeds.
From what I can find, that isn't one of them and should take maybe an hour & a half to transfer 30 GB to it. Of course if write speed IS USB1, then you could expect 2 days or more.
I'd stop it. Reformat it, then make the Image on the HD and try transferring it.

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.

Yosemite showing old icons for Hard Disks and Disk images

Hey all,
I'm running OS X Yosemite, all fully up to date, based on an upgrade install from Mavericks. Everything's basically fine, with the exception that any sort of disk icon (Internal, USB, Disk Images etc) all still use the old Mavericks style icons.
Not a major issue but kind of irritating me at the minute, I could go through and manually change them but I still get the old ones appear when a new disk connects.
This behaviour is exclusive to my user account as when I set up a second user to investigate all icons were the new 'flat' style.
Has anyone come across this, and if so did you find a resolution?

Mine look the same. Were they suppose to change?

Trying to create a password protected disk image in 10.8.4

Trying to create a password protected disk image in 10.8.4. I follow steps in Apple:Support but I get an error saying "Resource busy"?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

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!

Unable to burn AUDIO to DVD or Disk image, video is fine

As many other posts have stated; I am unable to burn the Audio portion of an iDVD nor does "save as disk image" transfer the audio of my iDVD. Transferred an iMovie, (an iPhoto set of photos with iTunes audio imported into iMovie) to iDVD. Audio plays on iMovie, audio plays on iDVD preview. Tried removing recommended ~com.apple.iXXX.plist, no help. Tried different encoding methods: i.e. Best/High/Professional. Tried saving to different sizes HD/Large/etc. Tried Share Media in iTunes, Media Browser, etc. Checked Main Audio, volume slider bar in iDVD. Tried importing audio into iDVD rather than transferring from iMovie. It doesn't seem to matter how I build the iDVD it works, until I go to Save As Disk Image or Burn DVD. Video works great (better in Large than HD) Audio doesn't transfer.
21 total minutes, 1.15GB of final iDVD using a default theme.

Hi
(an iPhoto set of photos with iTunes audio imported into iMovie) to iDVD
Yes this is the problem - in iTunes there is a copy-protection that moves over
Result
• Plays well in iMovie
• Plays well in iDVD preview
• Silent on DVD
Only way around this is to in iTunes collect needed audio into a play-list
Burn this out as an Audio-CD and .aiff (NOT .mp3)
Use the audio on this CD in Your iMovie project.

Backing up and restoring using disk images.

Hi there
I want to create a disk image of a mac's HDD, then put the disk image onto secondary internal HDD, so that in the event of the mac going belly up, I can start from the OSX system disk, format the main drive, restore from the disk image on the 2nd HDD, and off I go.
Using SuperDuper, I created a sparse disk image of the HDD onto the 2nd HDD. SuperDuper created a file called "HDDname.sparseimage". However, when I start Disk Utility and go to restore, it won't allow me to use the created file - the file is visible, just greyed-out.
I used a sparse disk image because I read that normal disk images will be the same size as the original folders/volume and are read only. I only want it the size of the actual data because of space restraints and would prefer to have it read-write too.
Is it a matter of just changing the filename from "HDDname.sparseimage" to "HDDname.dmg", to get DU to access it, or can DU not use sparse images?
Anyone shed any light?
TX
Macfool

Not sure if this will solve your problem, but I notice that although when I click on the Image button and navigate to a .sparseimage file, it is grayed out, I can drag-and-drop that same .sparseimage file into the Source field and it shows up.
Did you try Images menu > Scan image for restore and selecting your sparse disk image to scan?
Hope this helps...

Creating a Disk Image from Compressor Fails

Hpefully some one can help me out here.
Here's whats going on and I've tried this on 2 different systems (iMac 24 inch OSX 10.9.4,Nvidia GeForce GT750M 1 GB, 3.1 Ghz i7 Processor 1 TB Fusion Drive, 16 gigs of ram & a iMac 27 Inch OSX 10.9.4 Nvidia GeForce GTX780M 4GB, 2.5 Quad-Core i7, 16 gigs of ram 1 TB Fusion Drive, both have the USB Super Drive from Apple connected to them)
Both are running Compressor 4.1.2. I'm trying to make a disk image from a Apple Pro Res 422 HQ Quicktime 29.97 DF (drop frame, NTSC) The file is big since it's HQ so it takes a while to compress. I'm using the Create DVD preset in compressor and choosing " When Done: Create DVD" then below that "Output Device: Hard Drive" Because I want to have a disk image for back up and future burning so I don't have to tie up any systems doing this again.
It get's the the very end where it has that disk burning icon come up on the dock and then a warning comes up saying that there was a "error making the disk" and then that's it. I want to be able to create a disk image. Old compressor (3.what ever) works great, takes a lot longer to compress things but at least I haven't run into this issue with it.
I've had my destination set to the internal drive's, external drives .... you name it I've tried to save it in different places. I've added a background picture, removed it, nothing seems to work ....
Please help and much appreciated if you can help me out here.
Cheers

Yes it is. This should help you.

Disk images not mounting

Here's the question: how come .dmg files downloaded from apple.com (amongst other places) won't mount?
Here's the detail: This has to be a FAQ going by Google searches. I've downloaded the Mac Firefox DMG 3 times, and the Safari DMG from apple.com once, and when I try to mount the images I get a range of different cryptic errors, including "codec overrun", "not recognized", "error -some number or other", and so on. Sometimes, I get two different errors for the Safari image.
Existing disk images on my hard drive mount fine. Today my hard disk has been playing up, with files being corrupted, keychain being broken, prefs disappearing, and so on. I boot from the Tiger DVD, run Disk Utility and Repair Disk, tells me no repairs carried out as all hunky dory. Use Disk Utility on the HD to check permissions, those are fine. Run Onyx maintenance, all is fine. I've not changed the router prefs at all, so it's not that corrupting the downloads.
All was fine until mid-afternoon today, when a number of apps (Firefox, Safari, Dreamweaver) started behaving strangely and the machine kept on hanging. On restart a number of taskbar icons became question marks, so something's being corrupted. Some downloaded PDFs became corrupted.
What I might try to do is download DMGs from my work PC, put them on a stick, and try to mount them. If the problem recurs then that would eliminate download errors.
My conclusion is that either the OS has become damaged, or the HD is physically fubar'd, or at least has some physical errors on it somewhere which DU isn't picking up. If the latter I'm screwed as I'm out of warranty and I might as well chuck the machine in the bin, so let's hope it's the OS. I could reinstall the OS (again) but a) that would be highly time-consuming as I'd also have to reinstall a shedload of apps, prefs, configs, etc, and b) if there's a physical HD error it'll do zero.
I've already spent some fruitless and frustrating hours today on diagnosis, and having done tech supp in my career I know what to look for, so this is my last throw of the dice to try to get some kind person to suggest a) a diagnosis, and b) suggestions for a cure.
Without a cure I might as well take a clawhammer to the thing and get a Linux laptop. Ok, PCs are far inferior to Macs with crappy hardware, but at least you don't lose over a thousand quid when your PC laptop fails.

I was able to get a partial fix of this problem by following instructions that I found on the All Experts web site:
Regarding disk images and mounting media:
delete the following files and folders:
* /System/Library/Extensions.kextcache (file)
* /System/Library/Extensions.mkext (file)
* /System/Library/Caches/com.apple.kernelcaches (folder)
(Note that after deleting these files you need to reboot your Mac for the fix to take effect.)
All of these files and folders were date 18 Aug 2009, which is in around the timeframe when I installed the last security update for OS10.4 ppc.
I say the solution is a partial fix, because it did allow me to open some, but not all .dmg files (the problematic ones are showing a checksum error). Now I find that iTunes will not operate (yeah I know that should be another thread), but I have not used it in several weeks, prior to the last OS update.
