Disk Image issues

Hi, I've downloaded this .dmg file and I can't seem to open it. If I double click it is says "no mountable files" Does that mean there was an issue with the download or am I trying to open it incorrectly? I've been fussing in Disk Utility but i don't really know what I am doing.
any help would be great. Thanks!

Not really. Are you downloading via dial up modem? If so and it's a large file, then expect errors to occur. Downloading large files via dial up is always problematic. What is it you are trying to download, specifically?

10.4.7 Disk Imaging Issues

We have been using a disk image for all of the machines in our department. As updates become available we typically install the update on the Main Image system then use Disk Util. to Restore to other machines..The machines are identical. Every system we have tried to image since then only go about a qtr of the way before giving the error: "RESTORE FAILURE - An Error (2) Occured while copying (no such file or directory)
This is the first time the issue has occured since we began imaging systems a couple of years ago.
Any Ideas?
G5 Dual Core Mac OS X (10.4.7) Problems after 10.4.7 Update

Are you restoring an image made from the 'main image system' or directly from its drive? Have you prepared the image for restore by doing a 'scan for restore' for it? If so, does the image checksum verification pass the image fie? What image format did you choose?

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)

Issue with size of disk image on an external drive

I am trying to make a 900GB encrypted disk image on a new (blank) Lacie 1TB external drive. When I try and do so, I am told that there is only space for a 500GB image. When I tried to do the same thing on a Seagate 1TB external drive, I had no problem in doing so. Lacie tells me that it's an OS issue and not a disk issue. Any thoughts as to why this is happening?

I had already contacted LaCie; they weren't too interested and told me to contact Apple. I contacted Apple and the tech guy said that in order to create a diskimage of xGB, one needs 2xGB space on that drive. I don't know why that is and I didn't ask and nor did I have the energy to ask why it then worked on the Seagate drive. He said I can use FileVault 2 to secure the external drive...

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
Message was edited by: James Kilgore
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.

I am having issues with Time Machine. Error message "The backup disk image could not be created.

Error message "The backup disk image could not be created." I have tried everything I have found online in the community from TM full reset to changing my computers name. Anything else I can try? I am using a Seagate external HD with a connection through my router. I spent an hour on the phone with seagate and everything is ok on the HD end.
TM sees it and it is mounted but cannot go any further. HELP?!!!!
Thanks

How should it be connected? It has a usb port and ethernet. The USB on the ExHD looks like the port on the back of my computer, so I would need one wth the same ends? Do they make those?
I can usually fix most my comp problems myself, but this new ExHD has stumped me.
Thanks for your help.

Exporting to Disk Image Causing HD Issues

hi all. i've been exporting my dvd's as disk images onto an external hard drive, but every time i do, my internal hd loses a significant amount of memory as well. all project files are also located on the external drive, so there's absolutely no reason that it should be affecting my mac's internal hd that i know of. any suggestions? i've tried searching my comp for any files created or modified, but it finds nothing.

During the process of Burning a DVD, or to a folder, many more files are created, than what will be finally written. These working files are usually eliminated after the process has completed.
One can watch similar, when Exporting a muxed MPEG-2 file from PrPro, or most NLE's. If one has Windows Explorer (or the Mac equivilent) open, they'll see both the video and the audio files being created, then the muxed file is "assembled," and the elemental streams are eliminated.
Why your "working" files are not being eliminated, would be a concern. Off-hand, I do not have any idea of the cause of this.
One question: what version of En are you using? CS4 PrPro does do some files to C:\, during Export, etc., that were not created outside of the Scratch Disks, in earlier versions.
Good luck,
Hunt

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?

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.

Cannot delete disk image from timecapsule.

I have two disk image's on my time capsule and one is for a computer I no longer have. Therefore I wanted to delete the time-machine disk image. I recently upgraded to Yosemite.
In order to delete I have tried the following:
Mounting the time capsule and dragging to trash. Get a progress bar that says "deleting one file". It sits there over night and does not delete.
Going into Time Machine, navigating to the disk image file, right clicking, and selecting delete back-up. Asks if I sure and then does nothing.
Repeating the above with time machine turned off.
Disk Utility does not see the mounted drive.
Get Info on the drive says that I have no permissions and they are custom.
Tried some CHMOD commands I found on the internet and i got a series of error messages about CHMOD not possible.
If I double-click the disk image, I get a file not mountable error.
Time machine still works to back-up my current drive.
Any ideas????
Thanks,
Tony

Yosemite is problematic to say the least.
Delete backups was pretty much as you have done.. but Yosemite has the networking ability of tin cans and a broken string.
There are other ways around the issue..
How do I delete a time capsule Sparse Disk Image Bundle
There is a post at the bottom with a new method using a program I have not used but worked well.
I have a post there near the top with the standard methods.
I have good success btw with a windows computer on the network.. windows seems to treat permissions with contempt.

I run OSX10.6.8. Just dwnlded FF8.1 and everytime I go to open it I am asked about the disk image. But if I delete the dmg, the program won't run.

I just downloaded the 8.1 version. It was a 30+mb file. Previously I ran 4.0. So I drag the new Firefox icon into the Apps folder. It does its merge thing with the old version. Problem is when I click to open FF now, it always throws up this window asking me about the disk image of what I just downloaded. I even tried restarting the computer--but the same message pops up. I checked on your website and it says that I need to "eject" the disk image (i.e. I'm guessing that means the 30+ mb file I just down loaded), so since I don't have an eject option that I can find (except for external harddrives and cd/dvd), I just drug it into the trash. I go to empty the trash and I get a message that that dmg file is "in use" even though FF is completely shut down. So again I'm guessing that means that even though I already merged that dmg file with the old 4.0 version file, if I dump the update file it seems that it's going to mess up the actual revised program file still remaining. I just want to be able to click on the icon in my dock like I've always done and have FF open. I don't want to keep being asked about disk image stuff. Somehow this feels like an easy resolution, but I just can't seem to put my finger on how to resolve it. Thanks for you help.

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.

If anyone can help woold appreciate it.

This is a standard issue..
Been around since LION but you missed out.. !! Well the old rule applies.. there are three types of Mac users.
1. The bugs have bitten you, and you have done the work arounds.
2. The bugs are biting you and you are now trying to find out what is going on.
3. The bugs will bite you. And in the meantime you laugh at everyone with problems and say it must be all their fault. Doesn't happen to my system.
You were simply in the last group.. now, with the wonders of mavericks to help, you got bit.
The solution is simple.. unplug the power cord from the TC .. count to 10.. power up the TC again.
No luck look at the more technical help.

Your naming might also be an issue if this continues to happen.. see C9.

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.
