Disk image for restore won't verify

Hi - I'm preparing to send my G4 Pbook (10.4.11) for repair.
It was recommended that I make a disk image of the HD "just in case".
So I booted from the original install disc (10.3), launched Disk Util and made a new image on an external drive. Read only, not compressed. About 3 hours later I had a DI and decided to "verify" it. It would not. So I rebooted from the normal system and tried to mount the new DI. It would not and gave a message "the DMG is faulty and it may damage your hard drive if you mount it". So I trashed it, emptied the trash and used DU to erase that external drive in ready for the next try.
DU Help files are short and pretty clear. What did I do wrong? Can someone please give me a procedure I can succeed with?
TIA

Don't make a disc image. You cannot boot from one and they can be finicky. They are not what you want. Instead you want to clone your hard drive to an external Firewire hard drive. It's done as follows:
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the drive to which you will restore or backup.
Source means the drive you are restoring from or backing up.

Disk images PPC -- x86 won't verify

Not sure where my problem is, so here's all the info (this happens always):
I've discovered that when you download a disk image (dmg) made with a PPC from a PPC using sftp to an Intel Mac, that the disk will fail verification ALWAYS. Sometimes I think the disk will mount, but sometimes it refuses to, and it doesn't matter whether the image is read-only and uncompressed.
15" MacBook Pro 2Ghz • 12" PowerBook 1Ghz Mac OS X (10.4.6)

This is a strange problem. I am going to have to try to reproduce it on my system.
In the meanwhile, try opening Disk Utility. Try using the Convert... function, which is usually used to change a disk image from one format, say read only, to something else, such as encrypted. Try converting it to another type, specifying a new disk image name.

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 - Scan Image for Restore - Freeze

I backed up my wife's iBook by starting her computer in target disk to my iBook which has a huge external attached. After about an hour, the image process was complete. Apple disk utility help says next to scan image for restore (not too sure why because I'm not restoring anything unless her drive dies). I begin the scan image for restore and get the progress bar that never shows and progress. Just keeps spinning/scanning for hours and I have no option to shut if off. Can't move external to trash because it in use, etc.
Does this mean the original disk image may be bad? Do over?
I'm using Disk Image as a solution for a total disk backup if a drive fails. No messing around with reconfiguring apps, etc. (i.e. plug and play) Is this the best way to do this?
I come from the Mac Plus days. Hopefully I can contribute to the new OS discussions at some point. Thank you much!

What format is the external drive?
Is it Firewire or USB?
Does the external drive have one of those front button touch things, like a My Book?

It can take quite awhile, and the progress bar isn't accurate at all, but it sounds like something is wrong.

Disk Utility: after creating the .DMG (compressed image) When "scan image for restore" finishes it displays "unable to scan (internal error)". Since the process was scanning for about 1 hr is this a fake warning?

External 500GB drive is partitioned with 400GB for Mac OS extended (journalling) and 2nd partition formatted today as "ExFAT".
Yesterday I tried to create a disk image of my HD to no avail - this was compressed on a FAT partition. I got a warning after running the <scan image for restore> saying "unable to scan (internal error)"
I rang Apple support who suggested formatting a partition as MAC OS extended (journalling) and choose to save the image as "read/write'. The image process stopped writing at about 200GB and then the file size jumped to 499GB (ie the size of the HD). But the process did nothing for about an hour so I foce quit disk utility (as suggested by apple support)
My current attempt was to format the external drive again; this time with a 400GB Mac OS extended (journal) format; plus a 100GB ExFAT format partition. The new image was created after about 2.5hrs with a compressed size of 149GB. However, after running the "scan image for restore" facility I got the warning message "unable to scan filename " (internal error). The process was scanning the image file according to the progress bar - this took about hour - thus the warning is a puzzle.
If anyone can say more about this error I would really appreciate knowing tips for using disk utility. The screen grab is below.
"unable to scan filename " (internal error)
thanks

Thanks for a quick reply <baltwo>. You’ve answered that it is not a fake message!
fyi: I thought that I would use my external Buffalo for two purposes; namely the smaller ExFAT partition for copying stuff to my win7 netbook. The larger partition was to be used as my imac image of SL. So this was my first attempt at using disk utility - the idea being to hold an image backup at another location. Plus I now have the Lion thumbdrive ready to upgrade from SL and so being cautious wanted to have a SL image backup
Anyway I followed the apple instructions using my mac 10.6.3 install DVD but it would appear from other discussions that <unable to scan (internal error)> is not unique to me.
I’ll get back to apple telephone support for further advice.
I would though be grateful for an “idiots’ guide to making an image backup of my internal HD that runs SL 10.6.8
eg should I have just one partition on the external USB drive? format it as Mac OS extended? create the image as compressed or read/write? Basically I’ll do whatever will work!!
thanks again

Unable to create a disk image for mass deployment or to restore on other

I am attempting to create a master 10.5 Leopard image that can be deployed to other Macs, but the restore process fails with the following error:
*Restore Failure. Could not find any scan information. The source image needs to be imagedscanned/scanned for restore.*
I setup the master as I want it. I've booted from another drive and used Disk Utility to create a new image from Folder. (If I try to create a new image from drive, I get an error that the disk is in use.) I've run the checksum. I've run the scan image for restore. All process with out any errors.
The error mentioned above occurs when I try to restore the image to another computer.
Has anyone else been able to make a master image for deployment without using Leopard Server?

Hello,
I am also getting a similar error, but not trying to create an image, but rather reading one I created before upgrading to Leopard. I was having some HD trouble (power surge during install of Quicktime 7.3) that put my HD in any unstable state (resistant to Disk Utility/Disk Warrior,) but fortunately, I'd cloned the HD w/ SuperDuper (anticipating possible trouble during the upgrade.) I then made a disk image of the BOOTCAMP partition on another drive. Now, after re-formatting the HD, installing Leopard and partitioning for Bootcamp, I am unable to scan the image before restoring the disk image to the HD. It might be a FAT32 thing, but I don't think so.
The error is: Unable to scan "disk0s3.dmg". (Invalid argument)
The disk utility log is:
2007-11-08 20:33:43 +0100: Scanning image “disk0s3.dmg”
2007-11-08 20:33:53 +0100: cannot scan read/write images.

Creating Disk Image for Solaris 8 Admin Pack

Hi,
When I download the zip files "Software CD Image" for Solaris 8 Admin Pack / Solstice AdminSuite 3.0 and "Documentation CD Image", I get a zip file containing the contents of an installation disk (ie files and directories) rather than ISO files for creating a disk.
lf I then burn these to a CD (in either UDF or 9660 format) and try to install, it fails for various reasons, not least of which is the fact that the top level installation file does not have X permission. I know that I could copy these files to the Sun, change permission and run from there, but for various reasons I also need to be able to install from CD.
Does anyone know either how to create a CD with the correct format / file permissions / etc, or alternatively where the correct ISO's can be retrieved?
Thanks in advance.

Partition before installing, then try it. Alternatively, use something like Carbon Copy Cloner or SuperDuper! to put a bootable backup/clone onto the partition. That gives you something that you can immediately verify. A disk image requires restoring before you can be assured that it's viable. I've beta-tested Panther through Snow Leopard and have never made a disk image, only clones. Finally, creating the disk image takes much more time to create than does the clone. Just my 2¢. BTW, the image is useless unless you can successfully restore it. I have no idea why it's not working for you.

Scan Image for Restore?

I created a disk image last night to prepare for my upgrade to Snow Leopard and then this morning moved to the final step of "Scan Image for Restore" and I was wondering if anyone had any insights into how long this would take. It's been running for about an hour now and the progress bar doesn't show any progress, just shows the fast moving blue hashes in the bar. Is this normal, or is it possibly hung up on something? Note, the light on my external drive continues to blink, which makes me think it is doing something, just not sure if it is progressing and this just takes several hours, or if something is wrong. Any help is appreciated.

It can take a very long time, depending on size of the Image, and even slower via USB.
I think a much faster, better, more useful method is to clone your drive, then you'll have a bootable version of exactly what you have now.

So I made a backup image of my HD.
After running "Scan Image For Restore" this is what showed up in console...

Mar 16 17:36:46 localhost kernel: jnl: writejournalheader: error writing the journal header!
Does that look right?
Obviously there was an error writing the journal header because it was read only correct? What about the "strategy err"? - Is that how the log's suppose to look after running "Scan Image For Restore"?
Thanks in advance folks!

Disk image for multiple restore . . .

I have more than a few units (same type) to restore to os x 10.4.11.
I've setup one unit that I want to create a disk image of to restore onto all the units.
Using disk utility:
create an image form the "Disk"?
or from the "Volume"?
My thoughts where that selecting the volume my miss some hidden files vs selecting the disk ?
What's the correct way to do this and why?

would one way not be bootable?
No.
seems like both ways work to ensure multiple unit restores from one image?
Those are different in that one stores only the specified partition and the other stores the whole drive; the bootability information is stored at the partition level.

Using disk images for learning games?

Hello, I've 2 g3 imacs running 9.2.2, and they are for the grandkids to use learning games on.
The kids are very hard on the software disks. When I found out about disk images I made them up, now to install them properly. The games are installed, but where to store the disk images? The desk top icons for the games will work after the disk images have been double clicked and the mounted disk image appears on the desktop, but when the imacs are turned off the mounted disk image is lost. How or where does one put the disk images in a safe place so the kids don't get at them, and the disks are mounted every time, without actually starting, when the Mac is started? Start up menu?
I'm planning on multiple accounts with them having a standard account with game privileges so they don't mess the whole thing up. If their accounts get too messed up for me to repair I figured on maybe deleting the account and opening up a new one? Any Ideas are very welcome.
Thank you,
EZ

Hi, EZ -
You're quite welcome.
I had a thought with regard to the disk image files. Are they in a .smi format, or are they in a .img format?
The .img format requires the assistance of the Disk Copy utility in order to mount the image. This is the standard format generated by the user version of Disk Copy. It requires that Disk Copy be available to Finder to act as a helper app in order to mount the image.
The .smi format does not - .smi stands for Self-Mounting Image. The user version of Disk Copy can not make this format; but I have seen a utility to convert .img format to .smi format. The slight advantage with this format is that Disk Copy does not need to be available to Finder.
In both cases the default is to run a checksum verification before the image is finally mounted. The delay caused by this verification can be inconvenient - verification is intended to confirm the integrity of the image after it has been copied, transported, or downloaded, but is usually not necessary when the image resides on a hard drive.
The checksum verification for .img file types can be removed. With the image not mounted, open Disk Copy. In Disk Copy's Preferences (Edit menu), uncheck the Verify Checksum item. Save the Preferences window. Then select Convert Image from the Image menu, navigate to the disk imge file from which you want to remove the verifiaction, select it and click the Open button. A new window will appear, similar to a Save As type window. Leave everything in that window untouched (unless you want to change the base name of the file - the extension .img should be left intact) and click the Save button. The image will be mounted, the original disk image file will be deleted, and a new disk image file created. Unfortunately creating the new image file takes quite a while since it is creating a new one, not actually modifying the old one - but it does get rid of the intrusion of the checksum verification requirement.
I verified on my G4/500 running OS 9.1 that a .img file (one I had made from a game CD years ago) dropped into the Startup Items folder will be mounted automatically at the end of the startup sequence. I also tested with an alias to the .img file, and it, too, worked fine - the disk image was mounted automatically at the conclusion of the startup sequence.
When you make the alias to the disk image file (the .img one), be sure you are placing it into the Startup Items folder, and not the Startup Items (disabled) folder.
If you have the machine set to use Simple Finder (which removes Finder's keyboard commands and many menu options for Finder), that may interfere with items in the Startup Items folder being run at startup. Or, it may not - I have not checked that.
*** Edit ***
I have verified that the alias to a .img file will mount the disk image even when the machine is booted using Simple Finder.
Another thought, related to Multiple Users - if you do decide to set up Multiple Users, and the disk images are of type .img, be sure to authorize Disk Copy for each of the accounts for which the disk images are to be mounted. If you have the disk image files in a .smi format, since Finder views that file type as being an application, you would need to authorize each of those disk image files for each account which is to have access to them.

Firefox won't insall into my applications folder. Says can't install because libsmime3.dylib is in use. I am running Mac Os 10.6.7 on a Macbook Pro. I can run firefox okay from the disk image but just won't install into the apps folder.

My system is a Macbook Pro running Mac Os 10.6.7 with a 2.8 GHz Intel Core 2 duo processor with 4 GB 1067 MHz DDR3 ram. The upgrade downloads fine, but when I try to drag the firefox image onto my appication folder, I get a dialogue box that says...Cannot install application because "libsmime3.dylib" is in use. I can run Firefox fine from the disk image.

Nope---didn't work. I've owned Macs for about 12 years so although I am brain dead on some things, I do have a working knowledge on most things. I only say that to say this--I did try holding down the mouse and choosing empty trash. It asks if I want to permanently delete what's in there. I say yes--and then I get the same identical message again-----'The operation can't be completed because the item "Firefox 8.0.1.dmg" is in use I can then click stop, or continue.' So apparently that complains the same way it does if I click it up on the menu :)))
As for item owned by---that's not an issue and isn't coming up. User is not a problem either as I am the only user on this system. There is only ONE file in my trash at the moment at that is this dmg file. Nothing Mac. Nothing owned by anyone other than Firefox. The problem seems to be that the dmg file and the original 4.0 FF file are working in tandem with each other--even though I have already drug the new 8.0 globe into the Apps folder and it updated the FF app with the new stuff. If I could force the dmg file to go away, I would do so, but at every turn the system is telling me it can't be done because it seems to think that dmg file is in use---even though everything is shut down and/or ejected. Hey--I'm getting ready to head out and won't be back till evening. I'll check back in this evening. Thank you again for your help.

Scanning image for restore

How does one scan or imagescan a diskimage for Restore in Disk Utility?
Hans

Thanks for your reply, Kappy. Unfortunately that didn't work. I'm trying to clone computers. Disk Utilities doesn't let me drag the mounted disk image to the source field.
The cloning, however, works great with Carbon Copy Cloner. I mount the disk image as you suggested, then select it as a source and the HD i want to clone as the target.
I'm doing all this with an external firewire drive. I boot from the external drive which has the disk image of the source computer on it. Then I tried to use Disk Utility as you suggested, but it didn't work. So I used CCC.
Thanks for your help.
