Making Disk Image...

I am burning a family slide show, and I need to restart, but I still have to burn 20 dvds. Question is, can I save this "image" to my desktop or movie folder so when I want to burn again I can just burn that instead of going through the whole process again?? There are 450 pics, and it takes for ever!!!!!
Thanks,
Jason

Hello Jason,
creating a disk image is a highly recommended procedure when working with iDVD. Not only can you store the image file for future burns, but it also prevents coasters due to high (and non-adjustable) burn speed in iDVD.

"Authentication error", making disk image

I'm trying to make a disk image of my OS X boot disk, as an emergency backup. I'm booting from the Installation CD that came with my Mac Pro, and using Disk Utility. I select my boot drive, click New Image, and tell it to save to an external firewire drive, compressed and encrypted. It starts and quickly errors out, with "Authentication error." What does this mean?
I've used 250 GB of the 500 GB on my boot drive, and my external drive is 120 GB. I'd rather tell it to skip some files to save space, but it doesn't give me the option to do that. Will "compress" get it to be small enough? Is this why I'm getting an error? I've repaired permissions before booting from the CD.

I don't know about the authentication error; however, to make a disk image of 250 GB source drive to a 120 GB target is an exercise in futility. There's not enough room. 250 GB? What are storing? A complete music store, the movies of Hollywood, or the pictures in an art gallery?
If you want an emergency backup of your 500 GB HD, then you'll need an external at least as big. BTW, making disk images for this purpose is fraught with danger since you can't ensure that it's good until you restore it to a bootable HD. I strongly recommend something like Carbon Copy Cloner, SuperDuper!, etc. instead. BTW, you can just drag & drop any data files from one HD to another. There's no need to put them in a disk image and certainly no need to encrypt things. If you decide to go the bootable backup route, move the data files to root-level and don't back those up. That should make your emergency backup a lot smaller.

Problem making disk image of Panther install cds...

Hi everyone!
I want to make a disk image of my Panther retail install cds...just to have a backup in case I lose my cds or something. The problem is on disk 2 I keep getting an input/output error using Disk Utility. I tried to use SuperDuper and I got the same and the log shows this:

Funny thing is I had problems installing my Panther recently and I had to disable the German package because of errors during install. Does this make sense at all and can anyone help me to make a disk image of my Panther cds?
Thanks in advance,

Hi eww!
Yes that might be possible? That's one of the reasons I wanted to make a disk image in case my cds would be damaged or something. It makes sense what you say because as I mentioned when I did my install I had a hang up with the German pkg and I just skipped over it...good thing I'm not German huh?
If I clean it up and everything and it's still the same problem what are my options? I don't see a way to de-select this package when making the disk image?
Thanks again,

Quicktime to iDVD - iDVD quits when making disk image

You folks helped me a hugely with the arduous process of producing a nice 45 minute iMovie->iDVD movie last year from my digi camera, which actually works (http://www.galfromdownunder.com/peru). Thank you! Last year I was flummoxed by misplaced chapter markers. It's not the case this time.
I am doing another one of a similar size, and am at the stage of trying to burn a disk image, but it keeps falling over with 'iDVD unexpectedly quits' after about an hour and half. This time I saved the little log that pops up with 'send to Apple' (does anyone actually read it if you do?) and have posted it here:
http://www.galfromdownunder.com/ftp/iDVD-crash-report-may2106.txt
I would really be so grateful if an extreme geek would mind taking a look before I try to reverse engineer this whole process further. The log always seems to stop at a place that says:
Exception: EXCBADACCESS (0x0001)
Codes: KERNPROTECTIONFAILURE (0x0002) at 0x00000000
The difference between this project and last year's is as follows:
1) In an attempt to save time and space, I bypassed iMovie, and concatenated the QT7 clips and moved the resulting final movie directly into iDVD.
2) Yes, I did see that the Chapter Markers I painstakingly inserted (using that arduous text file process described in QT Help, mindful of not putting one within 2 secs of beginning, end, etc etc) into the movie are not picked up by iDVD. Groan. Still, the disk image burn quit. Then I tried again with the second concatenated QT movie without chapter markers, but it still quit with the above report.
3) I moved individual files to iDVD fudge a separate 'scenes' menu. I know it means there is redundancy in the data now, but there is 4 Gb to play with, so why not....
4) The total capacity comes to 4.3 Gb according to the Status section in iDVD. When I clicked on the DVD Capacity button it said the total was 62 minutes. I thought it was under ... hmmm... had it set to Best Performance.
5) I have about 11.47 Gb free on my laptop. I even tried making the disk image to a 20 gb Lacie external Firewire drive but it still quit.
6) Is there any difference between moving a reference movie to iDVD vs a self-contained? Does the s/w resolve them for you at the end of the day?
Really appreciate help - I realize could/should get iLife06 and a bigger machine etc etc but since I managed to do it last year, why spend more money unless there is an insurmountable tech reason to do so.
Thanking you,

My. You sound like an advanced user, but that sounds like a very advanced crash....
You know, I'm not one of the great experts, and I'm here to try to learn why iDVD won't start with a "Missing (iDVD) Image" in the crash log, but I've also had very little success with QT editing. Assembling clips frequently produces a video that is corrupted between clips, and a save doesn't really produce a truly complete file from a series of clips. Usually, the file plays up to a broken video, and the video then freezes, while sound continues. Yet picking on the video at the cursor will restart the video, so it's in there, just broken. Common occurance, this. This can be validated when that malformed file is imported into MPEG Streamclip (free app, and a good one), with the import only loading the clips up to the malfunctioning clip. I'm guessing that iDVD is running up against a malformed section in your QT file, causing a crash against a incorrect behavior in how the code accesses memory.
What would I do?
Since there doesn't seem to be any "self-healing" ability in QT, and since you already have a QT file with times and bookmark names, you might be happier if you went ahead with iMovie, and used the QT file for a ready reference to recreate the video in iMovie. I've done this in remakiing a DVD from another DVD I've created. The recreation process only takes maybe 1/2 hour compared to the much longer first effort. Copying is easy.
I use Final Cut express myself, and like its quality, and use an external drive for movie making, so you can live with the 11gigs you have onboard using your Lacie. Given the sad behavior of iDVD on my G5 recently, not starting and all, I'm thinking that maybe another 3rd party product, like the highly recommended "Toast" may help me elude what I'm beginning to recognize as substandard Apple apps. Apple has annoyed me endlessly with my need to "convert" the standard 'mpeg' to use in Apple products, like Final Cut (even after the $10US upgrade to play mpeg). Perhaps that would be a long term positive for you too.
Like your current experience, I'm at the "had my fill" point with pure Apple apps. Too much dancing with them trying to get common communication to work and too little visibility into why malfunctions are occurring.
In any case, good luck on this fix. Hope someone can get you rolling.

Disk Utility not copying all files when making disk image

My OS is 10.6.5 and everything is up to date.
I have a dvd that was burned for me of a play my child was in. It was probably burned on a PC using out of date software for all I know. But it plays in a DVD player and also in DVD player on my Macbook.
I want to be able to share clips of it online with friends, and that has all been just fine importing from the disk image I created of the DVD using Disk Utility, using IMovie 09 to edit it.
HOWEVER when I got to the end of act one, chapter 7 in the DVD is only about 3 minutes in length. The disk image I created using Disk Utility does NOT include any chapter 7 (which happens to be the ending of Act 1) and so I cannot import it into I Movie in order to add it to my mp4.
When I explore the DVD itself with my macbook, it only lists twelve files (various BUP's and IFO's and VOB's etc) -- here they are sorted by file name
VTS022.VOB
VTS021.VOB
VTS020.IFO
VTS020.BUP
VTS013.VOB
VTS012.VOB
VTS011.VOB
VTS010.IFO
VTS010.BUP
VIDEO_TS.VOB
VIDEO_TS.IFO
VIDEO_TS.BUP
Now, when my husband took the disc and created a .dvdmedia file in it and I explore that, there are 14 files. All of the same 12 files plus two more. (The DVD itself has 13 chapters but the main menu doesn't allow you to select them.)
the other two files in the .dvdmedia package are
VTS020.VOB
VTS010.VOB
But I can't do anything with that .dvdmedia file except watch it.
So I'm trying to figure out how to at least grab even just that last 3 minutes from Act 1 either from the original disc or from the dvdmedia file, using Imovie. So far having no luck. Disk Utility leaves it out and it's my only bridge from a burned DVD to Imovie. I've tried creating a DVD master and also an ISO using DVDRipper and that does the same thing. Also if I open the original burned DVD with Finder it only shows me the 12 files not the 14 that show up when using DVD Ripper to create a dvdmedia file.

For what the Apple Store's charge you can buy almost buy a new computer.
Just for giggles I brought my old laptop in for a drive upgrade and asked, they wanted $600 for a drive that only cost $120 at the time and it was a slow 5,400 RPM drive. The new Mac's of a similar make were going for $1000.
I did the drive replacement myself, got a faster drive of better quality for $300 instead.
Then another time I asked for a RAM upgrade from 4GB to 8GB, they wanted to charge $400 + $35 for the labor.
The same RAM is on Crucial.com for $90 and all I need is a 00 micro phillips screwdriver.
So you see what's going on here.
I think what you should do, if your out of warranty/AppleCare, is to call up the local PC tech guy who also does Mac's and have them fix you right up.
They can offer more personalized care which you need. Clone your old drive to the new and everything.
With Apple they are overworked at the Genius Bar and just place roadblocks so you buy a new machine instead.
For instance, all new iMac's now have proprietary drive software installed on the hard drives for heat monitoring. So now the only choice a user has is to bring their iMac into a Apple Store for a very expensive drive upgrade, which a person then decides the money is better spent buying a new machine.

How do I mount a disk image that won't open?

I have an external drive Samsung 500 GB that was failing. I think my MacBook Air (10.6.8) caused it to fail because it wouldn't allow me to eject the disk even though I forced quit all programs. I eventually had to just unplug the drive and this caused the external disk to fail as it had not been ejected properly. Not my fault. It's the MBA's fault for not letting me eject the disk. Now the Samsung disk won't mount properly and I get a message that the drive is failing and I should save the data.
Anyhow, I used the free version of Data Rescue 3 to try and save the data on the failing Samsung 500 GB drive and move it onto a brand new Toshiba 1 TB drive.
I was unable to use the normal scanning function of Data Rescue 3 as the hardware of the drive was too damaged, and so I used the clone function on Data Rescue 3 to clone the data onto a non-failing hard drive, with the intent of restoring the data later.
I am not sure if I was successful in making the disk image. It hung up at the 99.6% point for about 12 hours when I decided to give up on it, and I shut down Data Rescue so I could eject the hard disks.
However, it would not let me do it. I tried force ejecting but still I could not eject the disks.
I ended up just unplugging the drives. I think the Samsung drive died almost completely then because it made a whole lot of clicking noises after that (it was only making a few clicking noises before that).
Anyhow, I plugged the Toshiba 1 TB drive into the computer again and used Data Rescue to scan the drive with the disk image on it to see if I could detect files on that drive.
It opened up the structure and I was able to see that most or all of the files were there (abbout 450GB of data) just from seeing the information about the files in the structure tree - the labels of the files (file type labels such as jpg, mp4 etc) and the size of the files, although I could not open up the files to check all of them.
I tested out the restore function of Data Rescue by downloading one file (<10MB) file. I am using the free version and can download one file for free to test things out.
It worked and I was able to save that file onto a second external drive (Western Digital 500 GB) I had plugged in. I had bought this drive just to do the data rescue.
So I think the files are salvageable and the disk image is OK.
However, when I tried to open the disk image in Disk Utility, by opening it as the source and choosing the WD drive as the destination I could not open it. I got an error message. I can't remember what the message was.
I tried just opening the disk image in Finder by just clicking on the disk image but it won't mount.
Is that because my hard drive doesn't have enough space? My Desktop on the MBA only has 12 GB free and the WD drive has only 500 GB on it even though the disk image is about 501 GB.
I don't know why the disk image is that size when the failing Samsung drive only had 450 GB of data on it.
Anyway, what should I do to mount the disk image?
I want to mount the disk image so that I can copy or move the files from it to another external drive so that I can save those files.
Is it because the WD is only 500 GB or does it mean there's a problem with the disk image I made?
Should I try Carbon Clone Copy? I use that to make backups of my MBA internal HDD though I have never used it for opening or making disk images.
I have never dealt with disk images before except for dmg files of applications downloaded from the internet.
I am trying to avoid using Data Rescue 3 as I have to pay for it and if there is a free option, such as Disk Utility, CCC or other, I want to try it to restore the data in the disk image.
Sadly, I think the Samsung drive is ruined beyong repair as it's making a lot of clicking sounds and doesn't mount properly in Disk Image and I get a message that it's beyond repair or something like that in Disk Utility.
So I am relying on the disk image I made on the Toshiba drive to restore my files.
(I think it was the last movie file that caused the problem because it was when I was trying to copy it onto the Samsung external drive, all the problems began - hanging up when copying it, not being able to eject the Samsung disk, causing hardware issues on Samsung disk and getting warning messages on Disk Utility.)
BTW, I learned how to eject a drive when it won't eject the normal way, I have to use command window and type in commands, but that's another post ....
Any advice?
I am thinking of going out and buying a second 1 TB external drive so that I have a disk with enough space to open the 501GB disk image on it, just in case that was the sole problem.
However, I am not sure that is the case, and I think there may be a problem with the disk image or I am not going the right way about opening it.
Thanks for any advice.

I think I've found the solution to this problem.
http://superuser.com/questions/19426/im-unable-to-mount-a-dmg-getting-a-no-mount able-filesystems-error
I am following the instructions here:
I ran into a similar situation. I did what simonair suggested and I received a message in Terminal that Volume mounted successfully. However It did not help me access the mounted Volume neither was I able to confirm the mounted Volume. Nor was I able to mount the image using Disk Drill or even scan through. Nothing succeeded.
Here is what I did to solve my problem. I see that in this post some suggested that we should convert name.dmg to writable file. I used the command from Terminal to convert but was not successful. INSTEAD alternatively, I used Disk Utility, attached the Volume (yes I got the same message again, ''no mountable system files'' however, Disk Utility nevertheless attached the image, which I was able to do before anyways. This time, I selected it and then clicked New image, and then selected image format read/write, not the compressed option. I created a new image. This time this image was writable however, it still would not mount using Simonair's solution. However, this time I was able to scan it with Disk Drill with exact file locations and folder hierarchy as I had. Recovering all from thereon was a breeze. Just remember: when you create new image of an attached volume and chose not compressed but read/write, you need to have a disk with exact amount of space that totals the total space allocated within that name.dmg file (not the amount of space the data takes). Mine was huge, and luckily I had an external disk with enough space to do that and it took about 5 hours for about 400GB of disk allocation. Good luck.
And so far it seems to be working. Even though the volume is grayed out on the left side of Disk Utility, I am still able to select it as the source for making a new disk image. I chose Read and Write and no compression.
The only thing I might be doing differently is that instead of choosing the disk image as the source, I chose the volume as the source. The volume is grayed out, but the disk image is not.
It seems to be working all right. Keep my fingers crossed.
If this doesn't work, I will use Data Recovery 3 as a last resort.

Are you trying to create a new file with the same name as an existing one?

Trying to create backup of BOOTCAMP with New Disk Image

Hi.
I am trying to automate backing up my BOOTCAMP partition. I thought automator might do it. I have it done but I have 2 problems.
1) It prompts me for my password before it starts. Other folders don't ask me, how can I stop automator asking me when it is making disk image from BOOTCAMP?
2) I get an error message Error code 28. See below. I have run this twice and get the same error message, same place each time. What is the problem.
Thanks for your help. Much appreciated.
!http://www.silverstoneschoolsparking.co.uk/grandprix/bootcamp%20automator%20err or.jpg!

Thanks JGG.
However, I see that development of Winclone has stopped which is a little concern.
Also I do not see how to automate it. Is that possible?
Can Winclone be added to Automator somehow, or back to the original question why is New Disk Image not happy creating an image of Bootcamp? I also tried selecting all the files/folders within Bootcamp instead of bootcamp itself, but that also fell over with same error message but at a different file.
I use Carbon Copy Cloner for backing up Macintosh HD on a schedule, but I really want something which can back up Bootcamp on a schedule, or by using automator. How can this be achieved? Thanks

Disk utility caps new disk images at 13 in pwd

This sounds crazy, which is why I'm posting it here. I'd love it if someone could try this because I've tried it on two different Mac Mini's (macmini3,1 - aka, 5 usb port version) and the same results. Snow Leopard 10.6.4, fully up to date.
I am making disk images of all the software the faculty here at the university will need to install. Using the GUI version of Disk Utility to create them. So far, three times this has happened. Each time at 13 items. Note that this is 13 ITEMS, not necessarily .dmg's. I tried consolidating dmg's into subfolders during the third go-around, but once the folder I'm dumping all the dmg's into reach 13 items (dmgs, subfolders, whatever), Disk Utility errors out during creating the next dmg.
If someone wants to try this, I'd love to hear the results.

The type of disc being made into a disc image doesn't matter. I'm doing this to back up university software for internal use only, but I've tried it with other content as well.
Storage is not the issue. This is a fresh install of Snow Leopard, with 160gb or so free. the first 13 disc images took about 9gb of space, the second set maybe about 20gb, and the third set about 15gb. Both df -h ./ and Finder's GET INFO show plenty of hard drive space.
This happened after the initial 13 discs and every 13 discs thereafter; no data is moved off the harddrive, it just needs to be moved out of the folder I'm dumping the images into. This is a valid workaround, but it feels like something is wrong.

Best Settings for making a Secure, Reliable Disk Image?

Hi guys!
Can anybody direct me to the best settings that can be used to make a secure Disk image using the MacOS X disc utility?
I wish to make my computer family friendly, yet keep my proffessional and private files secure/private and innaccesible to children and unautorized individuals. I have heard that files saved inside encrypted images (password protected) are also not indexed in the finder wich is perfect for the privacy I seek (this is true right?).
I know how to access the tools, but the right settings for making a trustworthy image remain elusive. Already tried with some of the formats and information placed inside...started becoming glitchy and unreliable, even after removing the files and making them unencrypted again.I'm abaout to try with the HFS+ format.
I cannot lose the files I wish to protect. But I need to secure them and if anything, be capable of backing up the image by copying it into a HFS+ formated external hard drive every once in a while. Can this be done?
Is there a risk of data loss in the encryption process? One of my external drives (FAT 32) even started to make unrelated neighboring folders "disappear" after making an image inside ( I though I could make an image anywhere and save stuff securely at that point...but nearly losing the entire cashe of info made me backtrack and simply avoid the process until i'm sure of what I'm setting up---so many compatibility problems!)
• Don't know what settings to use.
• Some say there is a small chance of a disk image being damaged or corrupted (for no reason whatsoever)...but having trouble right off the bat, with a brand new image worries me. WHAT ARE THE RISKS? Is the system unrefined and unrealiable?
I plan to make the Image a sparse file,using the HMS+ format, 400GB....regular encryption. I plan to copy all my sensitive stuff inside and delete unprotected copies. Risky? Are images unreliable in general? or where my glitches abnormalities?---Can the images hold collections of files or do they become more unrealiable the bigger they get (what I fear). I don't wan't to have to make dozens of images to protect my files.
Can a external drive be formated to HMS+ and accept a drag and dropped copy of a 400GB image? FAT32 will just not accept it. Would there be risk of the image being damaged in the transfer? NOTE that copying the data into an external drive would be to have a secure backup of the data. If I can't trust the backup to be carbon copy intact...it isn't a backup.
Securing files is really proving to be bothersome, despite having "refined" tools at my disposal.
Thanks for your help!

Do you place your backups on external disks? Are your external disks formatted HFS+?
Can HFS+ Disk image be Drag dropped into a HFS+ formatted external disk in order to copy them? or is the process blocked like what happens to large Disk images in FAT 32?
I'm trying to lock on to the right format to apply to everything. My steps will be:
Make the image: So far a sparse image in HFS+ format, 400 GB, No partition map.
Drag sensitive work to Disk image. Once transfer in complete delete originals.
Format an external disk into the journaled HFS+ format. Drag drop Secure disk image to back it up.
Do you see any problems with this process? Anything i'm missing?

Encoding process isn't working properly while making the disk image (or DVD)in my iDVD program. Is there a remedy for this?

I've used Old Toad's suggestion and made a disk image first because the DVDs I've tried to produce show a few pictures in playback and then go white. The slideshow works fine in the iDVD program, and in the initial rendering stage all seems o.k. until the encoding step. Then, it processes 4 or 5 pictures, then goes blank but the music continues to be processed. Is there a remedy for this (I know Apple has ditched the program and the optical drives.) I deleted the project and tried making it over from scratch, but no luck.

I am simply lookig for some help not an argument. I am not an RF specialist however have setup a few wireless networks in my tenure at Wynn Resorts. I fully agree that wireless networking is an art and a science however the powers that be in Network Land have toughted wireless networking is the easiest and quickest way to get two computers to talk with one another. As I previously said I have already turned one (1) MBP in for this problem and Apple decided to replace it because they could not fix the problem with my particular MBP. This MBP was running Leopard when the problems started
I am having a hard time believeing that there are several other devicces in my home that depend on a wireless network to operate and my MBP is the only one having an issue. I took this a step further and decided to see what would happen if I tried to connect wirelessly via Fusion. In Windows 7 I am able to print and scan to my hearts content without any issues. I am able to browse the internet as much as I want. I close Fusion and try to connect to my printer via wireless and nothing.
In order to get Apple to help do I need to get a Network Analyzer and capture packets when I have these problems? Out of the 1000 + posts is there a consolidation of which answer is the best? BTW I am accessing the internet via a wireless connection using Fusion and Windows 7.
In response to Linc's comments, I will look at the router specifications however I did not qualify that these devices are not using the wireless connection at the same time. Right now I would guess there are maybe two (2) or three (3) at the most that are actively transmitting / receiving information. -- Thanks

Odd things after making a Disk Image

Hello All,
I'm a admin for a large group of Mac's. When I did my last hardware upgrade we deployed 10.3 and I built a master computer with all apps and sys prefs configured for our group of users. I then took that computer and made it my master and used Disk Utility to make a disk image of that pre-configured computer on a firewire drive and distribute the image to all new hardware that came in. It all worked well and I had no problems.
All users have been upgraded now to 10.4. I went to build a new image from scratch from a 10.4 install disk, did everything just like the first time around, with one problem. When I boot from the Firewire drive and use Disk Utility to restore the image back to a new computer and restart on the HD I see more than I should.
I see the links to etc, var, usr out on the root of the HD as links. Anyone can just double click on them and go right into any of these folders. A friend of mine said that in 10.3 their was a file called .hidden, that was a list of these links that were invisible, but it is no longer in 10.4. Does anyone know why this happened and how to fix this problem?
Any help would be great. Thanks
John

Trying to make single layer disk image AFTER making dual layer image

Hi all
I wonder if you can help me.
I just made a dual-layer DVD image from a project and it created a 7GB file. Now I'd like to try a single-layer disk image at 4.7GB, something I did with an earlier version of this project, resulting in a watchable disk on a smaller TV.
Having made the 7GB image, Encore won't let me make the 4.7GB version but I don't understand why.
Martyn

Thanks John.
I don't know the answer to your AVI/MPEG2-DVD question. Sorry.
I simply imported my PPro sequences, built my menus and created the disk image for a dual-layer disk. Whatever source format that involves, that was the one I've used. How can I find out?
Is there an alternative way of building a disk that will allow me to choose all DVD/image/Blu-ray output options without starting again?

Making encrypted disk image takes hours?!

Before I made a Time Machine backup, I wanted to use Disk Utility to create an encrypted disk image on an external hard drive. This way, my computer backup is password protected.
So I set the file for 200G at 128 bit encryption.
That was 12 hours ago. According to the progress bar, Disk Utility is still only one-quarter done with creating the disk image.
Is it normal for Disk Utility to take a full day (possibly two) to create a disk image of this size? Is there any way to create a password-protected disk image quicker? (And, for what it's worth, the external drive is formatted for Mac OS Extended, Journaled.)
Thanks for any advice on this...

Hi, and welcome to the forums.
I'm not quite sure just what you're trying to do.
Are you planning to have Time Machine back-up to that encrypted disk image? If so, that's not going to work. When you start Time Machine, it will create a Backups.backupdb folder on whatever drive or partition you select, then place it's backups in that folder, not in a disk image.
If you want to encrypt your whole home folder, you can use File Vault (System Preferences > Security > File Vault). That will encrypt your entire home folder. But that's almost certainly vast overkill, and has many complications of it's own. Read up on it thoroughly before deciding to do it.
If you have a few files that you want to encrypt, create a (smaller) encrypted disk image on your internal HD, in your home folder. Then copy the documents into it, and securely-delete the originals.
Then TM can back-up your entire system "as is" -- without the overhead of encrypting OSX, your apps, configuration, and everything else in your home folder, but the disk image (and it's backup copy) will still be encrypted.

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.
