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.

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.

Disk Utility: new disk image takes forever- computer unresponsive-HELP!

Hello,
I'm using Disk Utility to create a "new disk image from folder." The folder is on one Lacie exernal usb drive, and the target location is another Lacie usb drive (150 GB free).
The folder is 55GB. After 3+ hours, the activity window still shows "creating image" though the progress bar has changed from blue to pulsating blue/white stripes and I have the spinning beach ball of death.
Computer is unresponsive and the only way to terminate is to press the pwr button until everything shuts off.
Why is disk utility hanging like this? (or does it take more than 3 hours to create an image 55GB in size?
I've had no issues with previously creating images, though these were all 15GB or smaller.

USB takes forever....the reason I got a Firewire Ext. Drive.
It's soooo much easier to make a clone doing the following.....
I like the free demo of SuperDuper to make clones. It's free, Tiger and Leopard ready and is easy to use. If you buy the full version you can do incremental backups.
You should use Disk Utility to do a Disk Repair, as shown in this link, booted up on your install disk, before you make a clone of it.
I then partition my external disk, in Disk Utility, with a partition that is the same size , actually a tad bigger, as my system disk. I then use SuperDuper to clone my system disk over to that partition.
With a clone on an external FireWire drive (USB drives are not bootable on PPC Macs but are on some Intel Macs) you can bootup on it to do your repairs or just run your Mac anytime you have trouble with your main drive. Be careful, there are a few external FireWire drives out there that are not bootable on PPC Macs. Check the drive's manual to be sure.

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 reports "resource busy" and can't create an disk image

HI,
Just succesfully updated to Mountain Lion on my MBA and iMac. No problems. A very smooth proces.
But, on my iMac the Disk Utility are not able to create new images at all! I'm not sure if this relates directly to the update, as
DU works fine on the MBA.
I have tried to create a simple disk image from a folder, sparse bundle disk images and sparse disk images - with and without encryption.
They al gave this output from DU: "Unable to create "MYDiskImage.sparsebundle." (Resource busy).
I understand from other postings on the web that others have experienced the same message from time to time, but have not seen a fix for it anywhere.
I can see the "disk iamge" in the DU window (left pane) but are not able to locate it with Finder or on the computer anywhere, but are even able to "repair the
disk image with DU, but then there is actually no disk image when trying to locate it. Very strange.
Any help?

Hi Darth,
Thanks for the suggestion. Somehow I managed to solve the issue (the question was posted in July), I think I restarted the computer a couple of times, but it's interesting that you mention Drive Genius and Drive Pulse, as I also had that app running!
Maybe Drive Pulse was also turned of here in my process and helped to solve the issue.
Anyhow, thanks.

Disk Utility Error 61 when attempting to create disk image on external driv

I would like to make occasional archive backups of my three macintosh computers. I bought a new Western Digital 2TB drive for this purpose, and formatted it as Mac OS Extended. Trying to do a disk image backup using Disk Utility, I follow the directions:
- Startup from an install DVD.
- Start Disk Utilities and select "Restore"
- Drag "Macintosh HD" into the Source box
- Click on "New Image" and select compressed and 128-bit AES encryption
This leads to the error message: Unable to create "....." (error -61)
I have enocountered this problem both with my iMac G5 and a MacBook, both running Leopard.
Does anyone know what this error means, what I am doing wrong, and/or if there is another way to create disk image backups? Help!

1. For reasons I don't know disc images seem to become more fragile the larger they get. They also can be subject to file corruption that affects the entire disc image, whereas file corruption on a clone would only affect certain files.
2. You cannot put multiple clones on the same volume. Each clone must be on a separate volume, but you can have multiple volumes on a single drive simply by partitioning the drive accordingly. Of course you need a drive large enough to accommodate each clone. Each clone should be to a space equal to the capacity of the cloned drive.
3. I'm not a big fan of TM, although I must confess it has become more reliable since it's release, especially with Snow Leopard. However, there are many backup utilities that can create clones, perform incremental updates, and archive changed files. See the following:

Disk Utility fails to create image from double layer DVD

I burned a double-layer DVD using iDVD. It plays fine on the mac and on set-top DVD players. However, when I try to create an image of the DVD using Disk Utility, I get "Can't create image 'name.cdr' (input/output error)". I've tried re-burning the original disk, but it gets the same error when trying to create an image. I've also tried each of the image types, all with the same result.

I was having similar problems, although I don't think my issues was related to a double-layer DVD. What worked for me was selecting File > New > Disk Image from Folder. Select the DVD in the file open/save dialog with the same options you used before (e.g., DVD/CD master, etc).

Disk Utility: What does "scan image for restore" do?

Before restoring a disk image, I know that I need to use Disk Utility's "Scan Image for Restore…" feature.
Exactly what does this feature do?

I asked because I didn't know.
I was helping someone upgrade his PowerMac G5 from the original 80GB hard drive to a 1TB drive.
Since the G5 can accommodate two internal drives, I could have simply added the new drive and used Disk Utility's "restore" feature to migrate his data directly from the old drive to the new drive.
But it was more convenient for me to work at home so I removed the old drive, and brought it home along with the new drive.
I couldn't connect both drives to my MacBook Pro, since I only have one SATA drive dock. So I did it like this:
1. Connected the old drive to my SATA dock.
2. Create a disk image from his old drive, saving it to an external USB drive.
3. Disconnected the old drive from the SATA dock and connected the new one.
4. Restore the disk image to the new drive
Of course, when I tried step 4, I got an error message about needing to do a scan first. That's what led me to this question.
I have a follow-up question: When I created the image, I didn't bother changing the default image format, which is "compressed." If I had given the matter a little thought, I could have created a read-only image, since I would never need to change the image.
If I had used read-only, would Disk Utility have created the checksums on-the-fly when it created the disk image?

Disk Utility - Restoring a previous image

Since I first bought my Mac Mini (February of this year) I've been using the disk utility to make occasional backups (disk images) of my partitions, in case I ever need to restore a whole partition (or create a clone of an existing partition - for example, so that I could test some new software that might cause problems). I've never actually needed to restore a partition (or produce a clone from one of the backup images) until today. However, when I first bought my Mac I did test this feature and it seemed to work.
A few days ago I realised that I'd soon need to clone a partition so I backed up my Mac HFS partition which is about 90GB in size (my internal disk being 500GB). I then used Coriolis iPartition to create a new, empty Mac HFS partition of the same size, then tried to use Apple's Disk Utility to restore the newly created disk image. However when I came to try the restore, I got an error saying that the image would first need to be "image scanned" before being usable. I then tried an old image that I created when I first bought the Mac and currently, that one seems to be restoring.
AFAIK I've used the same method to create both images so why did the old one work when the new one didn't??
Message was edited by: johne53

Hmmm.... I've just realised that none of the images I've created recently will verify properly. They all get to the end of the first stage (block checksum of partition #1) and then fail with "internal error". The only one which passes the verification process is the very first one which I created a long time ago. That one seems to complete two stages of block verifications (for 2 partitions) then one "file checksum".
If I try to select a disk image and use "Open Disk Image" (from the right-click menu) I get an error saying "Unable to attach [image-name].dmg. No mountable file systems." This happens with every disk image I've created, apart from the very first one.

Disk Utility Crashing and Disk Images Not Opening Properly?

Hi,
I got a new G-Tech 500GB external drive that I've got into three partitions. All of them have Tiger on them but the main one I'm using is giving me problems. I have Stuffit Expander 11 on here and when I try to open a disk image it looks like it's opening but doesn't. Also I try and open Disk Utility and it crashes on me. I did a repair disk permissions a few hours ago after restarting up again and it seemed to be fine but now the problem is back.
The other problem I have on and off is that out of the three partitions I'm supposed to put them in the trash before shutting down and sometimes the two not in use won't go in the trash.
Any ideas? The two other partitions I have right now I'm using for recovery stuff from my internal drive.
S.

Its the improper unmount of the firewire drive which is the problem. Try to reset all.
1. Shut-down your Mac, and unplug the power cord
2. Turn the power off on your external FireWire devices
3. Unplug the FireWire devices from the Mac
4. Wait for 5 min.
5. Plug the power cord to your Mac only
6. Restart the Mac while holding the Option-Apple-O-F, and keep holding until you get the ">" prompt, then release the keys
7. At the ">" prompt type:
      reset-nvram and hit the Return key
      set-defaults and hit the Return key
      reset-all and hit the Return key
the last command will restart your mac
8. Shut down your Mac
9. Connect all your FireWire devices to the Mac and turn them on
10. Restart your Mac.
All your FireWire devices should reapear, if not repeat the procedure
How to avoid the issue :
The only really proven way to avoid burning up a FireWire port is to connect all devices and to turn them on PRIOR turning on the Mac. Likely, one must unplug them and turn them off AFTER the Mac has been turned off. If you need to connect another device, then you're on for a shutdown of your machine...  It's a tad annoying but it guarantees that the FW ports won't be damaged.  Be careful when using self powered devices such as webcams, iPods, hard drives or hubs, as they can destroy the port pretty easily. Another thing is to avoid daisy-chaining hard drives.
When the FW port doesn't respond anymore :
In this case, peripherals won't be mounted upon plugging, and won't be displayed in Apple's System Profiler. The self powered devices will still be fed by the port, but won't respond either.  It happens that the PHY just hangs after a surge or a random problem. Once hung, the port will not respond any longer, it is possible to reset the component by going through the following steps :
1° boot the mac in Open Firmware by holding [ Apple key - Option - O - F ] after the startup chime.  2° you'll get to a command prompt. the keyboard mapping will be QWERTY, so pay attention when you type the following :  RESET-NVRAM (enter)  RESET-ALL (enter)  3° Now the mac should restart itself and the port should function properly again.  If it still doesn't work, then it means that the PHY is damaged.

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)

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.

Disk Utility: Restore Failure-Source image needs to be scanned for restore.

Hello guys,
I have a .dmg (source image) that I have created from a DVD by myself (read-only format).
I am trying to restore it to a destination and a Restore Failure notification pops-up as follow:
"Restore Failure
Could not find any scan information. The source image needs to be imagescanned/scanned for restore"
I am quite new to Mac. Half of the time, I don't really know what I am doing - but just relying on the 'Help Menu', some research for guides on the internet and most of all read-on most of the posting here in the Apple Forum for what I want to do or might have encountered. Lastly to hopefully also speak the Mac language. For example - What's a disk image? What a .dmg? What's a source image? and etc. ~Lost~
So for this case, I am totally lost as I can't seems to understand what does the Restore Failure notification mean at all as I quote above. What does it mean by the Source image needs to be imagescanned/scanned for restore? What do I do from there? How do I scanned my source image? Is there a steps that I miss out while creating .dmg from the DVD?
Could not find any scan information? What scan information? Where do I go to asked for scan information?
I am so lost that I don't even know the right question to ask or begin with.
I know what I want to do and believe it can be done with Mac. But I just doesn't seems to understand the concept of how it really works yet but to just follow blindly throughout the guides.
So please help me if possible.
Thank you in advance.
Best Regards,
Jon Gan

Hi,
If you open Disk Utility, select the Image in the disk util sidebar, and click on Images > Scan for restore... in the menu bar, it will take care of it for you. After that you can perform a restore as you were trying to do.
They do this so that disk util can verify your data after the restore to make sure it copied exactly.

Anyone know Disk Utility, Ignore Ownership, and disk image DL DVD issues?

I am currently having issues with backup DVD's I burned using Disk Utility. I can put the dual layer DVD's in and the system reads them. When I try to pull a file off the Dual Layer DVD a circle with an X appears notifying me that I cannot copy the files to my desk top.
When I check the DVD's permissions it reads Admin (me) read and write with the ignore ownership checkbox checked...which means I should be able to pull files off the DVD. The only way I can currently get information off the DVD is to duplicate the entire disk to a new folder by selecting the DVD while holding down the Cntrl key and selecting duplicate. I have had other issues with DVD's and disk images in Leopard....including having to eject either through disk utility or by selecting the image with the Cntrl key held down. Finder eject, keyboard eject, and the menu eject selections suddenly report that the disk is in use.
The DVD's were burned by creating a dual layer dvd image through disk utility with the read/write option checked.
After duplicating 2-3 disks, the system itself is unable to mount any more disks from the series of backups. When I look at disk utility it reads that the disk is not mountable. I have to restart my computer so the system can continue to read the backups.
My Itunes disk backups are marked the same way (ignore ownership) with admin read/write privlages....I have no problem pulling files off these disks.
I have tried both logging in as root and booting from an external drive...same problem. Is this some nasty Disk Utility bug? Is anyone else having bizarre permission related issues with Disk Utility and Disk Images.

When you create the image in Disk Utility, did you
change the 'Partitions' setting?
If you leave it to read 'CD/DVD', it will create a ISO9660/UDF image.
To be able to maintain permission and extended file attributes, you
need to select 'GUID Partition Map'.
I assume you used iTunes to create your music backup?
It seems it creates the correct image type for you.
Before sending this message, I actually created a single layer image,
copied some files to it and gave additional permissions to other users on my system.
Afterwards I copied the files to my Desktop, verifying that the attributes are still intact.
Best regards
(It took quite a while to burn this 4x DVD-RW Anyways, I hope I could help)
