Can't mount a .dmg file I created yesterday. "invalid argument"

I created two encrypted .dmg files yesterday using Disk Utility. They both mounted just fine yesterday and I haven't touched them since. I just now went to mount one of them again and it said "the following disk images could not be opened. (name).dmg reason: invalid argument.
I've seen some articles in here about the "invalid argument" error coming up on .dmg files created by a 3rd party, but the advice seems to boil down to "get a new copy of the disk" but obviously these are things I created myself so there are no other copies. And I deleted the files that I put on the .dmg's after I tested them yesterday and they both seemed to work.
Any suggestions?

Update: I shut the computer down last night and restarted it this morning, and it worked. But does anybody know what happened so that I don't repeat it?

Try to mount a dmg file -- Input/Output error

I have certainly searched thru postings, but I cannot quite find a solution.
[1] An external FireWire drive holds a lot of dmg files of application installers.
[2] Double-clicking some, not all, of them results in an Input/Output error.
[3] Toast is always able to mount them.
[4] When the error happens, an attempt to copy the dmg file onto the Desktop results in another error message "The Finder cannot complete the operation because some data in "<name>.dmg" could not be read or written. (Error code -365)". At this point, clicking on OK brings up a Copy window which hangs. The only way out is to Force-Quit the FInder.
What should I do to rectify these issues?

I appreciate your suggestions.
The external drive in question is OWC's Mercury Elite-AL Pro with FireWire 800 (2) and 400 (1) ports
It was purchased in February, 2008. Its original connection was thru FireWire 800 to my G5 Tower.
[1] Ports
      The G5 has only one FireWire 800 port, while the OWC enclosure has two.
      So, I used the other FireWire 800 port on the OWC.
      The same intermittent I/O error in mounting dmg files.
[2] Cables
      I tried another FireWire 800 cable with either of the two FireWire 800 ports on the OWC.
      The same intermittent I/O error in mounting dmg files.
      So, I switched the connection to FireWire 400 between my G5 and the OWC.
      No I/O errors after trying to mount numerous dmg files.
[3] MacBook Pro
      I disconnected the OWC and connected it to a MacBook Pro's FireWire 800 port.
      No I/O errors after trying to mount numerous dmg files.
From [1], [2], and [3] above, can I deduce that something is wrong with the FireWire 800 port on my G5 Tower? I thought that both FireWire 800 and 400 ports on the G5 Tower were controlled by the same chip.
Please advise.

Please list the specs for your computer.

I can't install any dmg files

I can't install any dmg files and I can't find CoreService nor DiskImageMounter under Library order neither. I think they're missing.
Please Help.

They should come up when you double click on the DMG file.
If you are getting a terminal windows when you double click on a DMG file then something has switched the Default program from Installer.app and or DiskImageMounter.app to terminal.
Right click on the DMG and select Get Info. In the windows that comes up find the Open with section then select DiskImageMounter.app and click Change All.
Both DiskImageMounter.app and Installer.app are in /System/Library/CoreServices. But that folder may be hidden. So you will need to use the Go Menu item "Go to Folder" and type in what I posted above to find it.

Can sombody please explain .DMG files to me?

Hi I have got varios .DMG icons on my desktop which relate to various programmes such as google earth, Messenger, Security and OSX updates from ages ago Etc.
Whats the deal with these? Can they be Deleted or will that remover the programme/update(i'm trying to keep my desktop clean and tidy!)
I'm also trying to prepare my mac for a tiget upgrade (from 10.3.9) and want to make sure there is as little chance of it gpoing wrong as possible.
I run mac janitor each week and i'll do a disc repair before and after the install. I'll also be burning all of my important files (pictures and i tunes library) to DVD'S. Just in case. Anything else i should be aware of?

'If' you install Google Earth on your machine, then it is indeed installed as a program. But you must install it. Merely downloading it, or any other program, to your desktop, whether as a disk image, or in some other format, is not the same as installing it.
Once a program is installed, you can indeed remove the .dmg file from your desktop exactly as 'roam' recommends.
As far as updating with the 10.3.9 combo, you must install it ie run the update. Just putting it in your applications folder will not do the trick. I would take it out of the applications folder, put it on the desktop, run it from there by following the instructions and then dump the .dmg file once the update is installed.
You should quit all applications before installing the update and will almost certainly have to restart your Mac once the update is complete. Some people also repair disk permissions using Disk Utility after installing new software.
Good luck.

TS1702 why can I not access a new document created yesterday in "pages"?

why can I not access a new document created yesterday in "pages"?

Hi,
Based on my understanding, your issue is you cannot create folder in Windows 7, right?
Did you fix it?
This issue might be caused by corrupted system file.
If I am right and you haven't resolve your issue, we could try the following method:
Run System File Checker Tool to repair your system file:

I can't open the psd file I did yesterday! It says that the file is not compatible with this version of photoshop.

I can't open the psd file I did yesterday! It says that the file is not compatible with this version of photoshop. I worked in a CS6 version but also tried opening in a CC but nothing happens. Help
more info:
Photoshop never crashed or anything.
I was working in my school's mac but running windows, and the file was being saved in the school's network not on the computer. I thought it had been saved and I also copy and pasted the file in my hard drive to guarantee a copy but none of the are opening.
The file size was appox. 1giga
Thanks a lot

The problem was saving over the network. Working across a network is not supported.
This is the boilerplate text often used in connection to saving to a network (please NOTE the part where it explains that normally, it does work, but that it is impossible to troubleshoot someone else's network remotely, and that's why it's not supported by Adobe):
If you are opening files over a network or saving them to a network server, please cease and desist immediately in the event you are currently experiencing problems with one or more files. Working across a network is not supported.
See:
http://kb2.adobe.com/cps/406/kb406793.html
Copy the CLOSED file from your server to your local hard disk, work on it, save it again to your local hard disk, close it, and copy the closed file back to the server.
Of course, the fact that Adobe does not support working across a network does not necessarily mean it won't work. It should.
Adobe's position is that there are too many variables in a network environment for them to guarantee that everything will work correctly in every network, especially given the fact that if something does not work properly, it's probably the network's fault, and Adobe has no way of troubleshooting your network.
If you can't work locally, you are on your own, and if something happens, you're on your own. If you must work from a server, make sure your network administrator is a competent professional.
When problems arise, a lot of valuable work can be lost.

Actually it's the first time I tried to set up one.
I Basically followed this guide [1] adopting it to arch.
That's where i got my nginx.conf from. Taking the standard nginx.conf that comes by install and replacing the server part.
After some searching I found the owncloud manual[2] with an example nginx.conf. Comparing that with my one I found some differences. Applying them works out fine.
I get now the owncloud page.
The systemd error still ocurs, but I think it does not matter to run the server.
Thanks for your help.

I can no longer make dmg files in disk utility since upgrading to Mountain Lion

Hi everyone,
I'm a videographer, and have been using the facility in disk utility to make dmg backups of my media cards. It's proved to be a neat and tidy way of doing things, and is my equivalent to storing videotapes.
However, I no longer can make them.
My technique has been to:
1. select the memory card in disk utility
2. press new image
3. browse to destination for the dmg/hit save
4. sit back and wait for the process to complete.
this has been working for me in Snow Leopard, but not in mountain lion. I can't identify any other variables that have changed except the OS upgrade.
Firstly 'Authopen' prompts me for username/password. After username/password it starts creating the image, but stops with an error;
"Unable to create "SD-Card.dmg." (Device not configured).
The card is sitting in a media card reader. I tried another card reader that resulted in;
Unable to create "SD-Card.dmg." (Input/output error)
Anyone experienced this, or any ideas on what to try? As the card readers both work insofar as they show the memory cards in the finder etc, could there be a disk-utility-specific problem with them? Or do I need to change my procedure? I can copy the files to the hard drive and make a dmg from a folder, but I'd rather not have to do that.
thanks.

Maybe just corrupted Disk Utility preferences ...
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Preferences/com.apple.DiskUtility.plist
Click Go then move the com.apple.DiskUtility.plist file to the Trash.
Restart your Mac then try creating a .dmg file.

Can't open the dmg file in Safari brower

My Mac can't open dmg file in Safari brower.

A .dmg file is the digital equivalent of a CD or DVD. Just like Safari can't "open" a DVD, so can't it open a .dmg. However, if it is already on your Mac's hard drive, you can double-click it so Disk Utility can mount it and you can examine its contents, like if you had inserted a data CD/DVD or plugged in a USB Flash drive.
When done, dismount it by clicking on the upward pointing triangle next to its name in the Finder window, under Devices.

Cannot mount a .dmg file

I just received a Slingbox Pro for the holidays. I downloaded their software, which is in the form of a dmg file. After the download it would not mount. The people at SlingBox are clueless. I'm waiting for a Mac specialist to call me back.
Any idea why it is not mounting? Just as a test I downloaded iTunes because it too is a dmg file and it mounted. They think it is some setting regarding a firewall or the like. Help...
Scott

That means that perhaps the file you downloaded got a little messed up on its way to your computer, or perhaps the checksum information wasnt included in the original file. Disk images have checksums to ensure the integrity of the disk image is ok. It works by summing up the number of bits and bytes in the image/file according to a summation algorithm that will give you a specific "checksum" number. The file should contain the checksum number (created and embedded in the file when the original disk image was created) that your computer compares to it's checksum number that it gets when it runs the same algorithm upon mounting the disk image. If the image is intact, then the checksums will match, but if the original checksum is missing or they dont match, then the disk will be avoided for fear of corrupt data, etc.
I'd recommend re-downloading the file, but if you want to try one more thing with this one, open "Disk Utility" and in the preferences uncheck the "Verify checksum" option. Then go to the file menu and select the option to open a disk image and hope it mounts without checksum verification. If it's just a checksum error where the checksum number is missing, then the contents should be fine and you should be able to install the program, but if there's a problem with the disk image then its likely the installer files will be corrupted and you will get errors. Its worth a shot...

Can't open new .dmg files

I created several .dmg disk images a few months ago using Disk Utility (from October 2009 to February 2010). When I created them, I made sure that they mounted properly.
Today, I tried to mount one in the Finder and got the message "The following disk images couldn't be opened" "Reason: not recognized". So, I tried to mount it with Disk Utility, and got the message "Unable to attach xxxx.dmg." (not recognized). The same is true for all of the disk images I created. Other disk images mount just fine. I tried mounting one of the problematic images in Toast, and after a few messages it mounted as an Audio CD (which it is not) with 1 track.
Any ideas/suggestions? Thanks.

I just solved this myself, having clicked on a related "More Like This" link after I posted...
After double clicking the .dmg file in my download directory and automatically launching Disk Utility, I selected the .dmg disk image in the left-hand column. I then clicked over to the "Restore" tab in the top-center of the Disk Utility panel.
In the upper row of control buttons, I clicked the "Open" icon. This was not an obvious choice because it is small and "Open" is not the function I was seeking. If you roll-over that icon it says it is for mounting or unmounting a disk.
The disk image then mounted on the first try AND once it was mounted the "Open" icon name suddenly changed (greyed-out) to read: "Mount." A bit of an odd and elusive process but much easier than other more invasive procedures (like "repairing permissions") to recreate that auto-mounting capability I had lost...

Can't open file i created yesterday v5.5 .psd

I just created yesterday a .PSD 5.5 file on an HP (64 bit, etc), and now I can't open it. Message says not compatable... I am using a trial version of CS5.5, but still have 15 days left. Couldn't open on a mac iin CS4 either.
Don't remember if I had "maximize compatability" on or not.

Seems to be several posts with the same problem on this page. No solutions offered yet. Keep track of those post also.
