How do I mount a disk image on an eMac?

Every blog I read says all I need to do is double click the image to mount it, but it just says "There is no default application specified to open the document " .exe"
It gives me the option to chose a file but idk what to do. Please help.

If it's a Windows executable file other than a self-extracting zip, you won't be able to open it without installing Windows; on a PowerPC Mac, this requires Virtual PC or the Q emulator.
If it's a self-extracting zip, StuffIt Expander will open it.
If it's actually a disk image, change its extension to dmg or iso and double-click it.

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.

How do you get a disk image to mount automatically at login?

I've created a disk image on my iMac in order to share my iPhoto library with multiple users. I would like it to mount automatically when the computer boots up, rather than having to chase it down every time a user wants to access photos. I know how to navigate to Login Options in System Pref/Users & Groups, but don't see any mechanism there for adding disks or apps to startup at login. Thanks...

Adding an application to startup. I'm not quite sure what you mean by mounting a disk image but you could pop your dmg in there and see what happens at login.

How do I create a disk image for windows 7, using a windows computer for USB bootcamp for mac?

Hi There, I have just bought a new 2013 iMac.
Spec: 3.4 GHz intel core i5, 16GB 1600 MHz DDR3 Memory , NVIDIA GeForce GTX 775M 2048 MB Graphics with OS X 10.9.4.
How can I create a 'disk image' from a windows 7 professional 64bit installation DVD using a windows laptop with windows 7 Operating system on? I want to transfer this 'disk image' (ISO?) to a USB ready for installing windows onto my 2013 iMac using bootcamp? I want to use bootcamp from a USB as I have no disk drive for the installation DVD on my iMac. I hope all this is clear.
Thank you. Joe

Yes, that's correct, at least not directly. You can create a blank disk image, copy the file to the mounted disk image, then burn the image to a CD/DVD.
Open Disk Utility and select Blank Disk Image from the New menu. Provide a name, Save location, and select the image size from the drop down menu. Leave Encryptions at None and Format as read/write. Click on the Create button.
After the image file appears the "removable" disk should be automatically mounted. If not double-click on it to mount it. A "removable" disk icon will appear. Drag the file you want to place on the disk image to the "removable" disk icon. The eject the "removable" disk icon. Now select the disk image file in the DU left side list and click on the Burn icon in the DU toolbar. Be sure to have a blank disc ready.
The above is actually the "long" way to do this. A much easier way is to simply insert a blank CD or DVD into the optical drive. The Finder will pop up a dialog asking what to do. Select the option to mount on the Desktop. You will now see a disc icon on the Desktop. Drag the file you want to burn to the CD/DVD, right-click or CTRL-click on the disc icon and select Burn from the contextual menu.

How could i mount the usb image drive at the desktop?

i'm using Lion and since my new computer has arrived I got a little disapointed! First, and at least for me the more awful issue, the image of a pluged usb drive DO NOT appear at desktop!!!!!!!!!!!!!!!!!!!!!! how could that happen? it was a very usefull treat! my hope is my ignorance: i think i'm not dealing properly with my new computer, i really hope there is a hidden way to activate that!
second: why **** the quickplayer DO NOT recognise subtitles? every time i try to watch a movie with subtitle the quicktime closes and the quicktime 7 opens!
third: why activity monitor DO NOT show the right disk free space? even erasing huge files the available free space is frozen! do not increase!
sorry for my english mistakes!

Thanks for the reply. I was able to save the data on the Macbook Air whose HD got corrupted by using File Sharing (ethernet connecting two Macbook Airs).
I am also going to make a disk image of the HD using Disk Utility and mount that Disk Image onto an external hard drive. That way I can save the hard drive contents.

How can I create a disk image of snow leopard installer disk from my Imac which runs it?

how can I create a disk image of snow leopard installer disk from my Imac which runs it? It came without DVD installer, and I want to make a copy of it's OS installer but can't find out how.

You need to have the disc in order to create disk image of snow leopard installer disc. What did your machine ship with? If something later than SL, then why? If earlier, then you can buy the SL installer disc and make the disk image.

Thanks for getting back to me, Yes it does, it came with the machine.
Hi pfhannon,
Does the original Install disk that you are copying,
boot your computer?
You may be successfully making a copy of a disk that
is not suitable for your machine.

Even though I have LCD font smoothing disabled, Mountain Lion still uses it in PDF views, Safari's location bar, Mail's message view, and the dialogs for mounting encrypted disk images.

Even though I have LCD font smoothing disabled, Mountain Lion still uses it in PDF views, Safari’s location bar, Mail’s message view, and the dialogs for mounting encrypted disk images. Is there any solution to this problem? Also diabled the Smoothing in the SystemPrefs and also via Terminal. Font smoothing is still there. Very annoying, especially in PDF attachments in Apple Mail.

Try feeding Safari a user-defined CSS file with font-smoothing tweaks (including none). The filename and its filesystem location are arbitrary. Use your favorite coding editor.

Here is an example with all elements uncommented. Pick the one that works best for your Safari viewing and comment out the others:

If the image is open (you'll either see the image's disk icon on the desktop or in the left pane of the Finder window) close it. Then put the image in the trash and empty. If you don't close the image it can't be trashed.

An error has occured attempting to mount a disk image "5" error #5

for quite some time now, i have not been able to load programs. it seems to have started after i did a firmware update that was meant for a OS 10.5 system and mine is OS 10.4.11. ever since then, every time i would click on "Software Update", nothing would happen, if i were to upgrade to itunes to 8.0 whatever, nothing happens. if i were to try to mount with stuffit expander i would get the following error: an error has occured attempting to mount a disk image "5", error #5. it is getting very frustrating.
any help will be appreciated.

Hi Watsmaster, and a warm welcome to the forums!
If you haven't done any Disk or OS maintenance, then I'm thinking corrupt HDD or possibly some Hardware problem.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

HELP ! Last To Sec . Updates causing problems-Won't mount any disk images

Just installed most current 2 updates Mac OS X v10.5.8 (Leopard) & now can't get my system to be able to mount any disk images of any kind. Internal expander gives me Mounting failed
Also tried to expand with Stuffit and got following message:
SecUpd2009-003.dmg no mountable file system.
SecUpd2009-004.dmg no mountable file system.
This first started with 2009-003 update and now 2009-004 it continues.
Also completely erased my backup external HD files.

If you did not repair permissions after updating, then try the following:
Try running +repair disk+ from your *software install DVD* and afterwards, run +repair permissions+ *from your HD.*

How to backup a mounted & encrypted disk image?

I have read all the posts about creating a sparse bundles. I guess this allows you to backup the disk image as long as it is not mounted? Will it still backup if it is mounted? Will it be usable when I restore it?
What if all I want to do is just backup the mounted disk and not the image? I did some tests and it seems to work. When I look at the backup on a different machine by taking over the disk, I see the volume as a possible restore and I see the files. Am I missing something? I thought I had read that this does not work? I do realize that the backup is not very secure since I can now restore files on an image I had intended to maintain secure. It would be nice if time machine allowed me to backup in an encrypted format the required some password for the restore. Create sparse bundle on that backup disk and backup to that mounted image?
Steven

Well since it is encrypted, no matter how you delete it, it should remain secure. That is an advantage of an encrypted file
However, if you want to over write the contents of the file, you can just drag it to the trash and select secure empty trash.
NOTE: if you have a lot of other deleted files in the trash, it is going to take longer to do the secure empty trash as those other files are also going to be securely erased. I've made the mistake of doing the secure empty trash with several hundred files in the trash, some of which were rather large files.
