Problem with mounting disk images

I have recently downloaded a media player and have had some problems. When I download the file to my desktop and try to run it, it gives me a "warning" window. In the window, it says that "the following disk images failed to mount" and gives "device not configured" as the reason. The file on the desktop's path is .dmg just to be more clear. So...yeah...any advice??

Just to make sure (I don't think this is your problem, but it's easy to check), make sure /System/ Library/ CoreServices/ DiskImageMounter.app is present on your Mac.
Do you have another user account on your Mac? If necessary, use System Preferences> Accounts to create a new troubleshooting-only administrative user account. Check if that new user account can open .dmg files. If it does, that indicates a problem with the preferences in your normal user account. Use Preferential Treatment to scan your prefs. You can also drag the ~/Users/ [yourusername]/ Library/ Preferences folder tot he desktop, log out and back in, and see if .dmg images work, then move your prefes back from teh Preferences folder on the Desktop to the one in ~/Users/ [yourusername]/ Library. Or you might just try moving these prefs to the Desktop:
/Users / [yourusername]/ Library/ Preferences/ com.apple.frameworks.diskimages.uiagent.plist
and com.apple.LaunchServices.plist
If the troubleshooting user account also shows the problem, first run Disk Utility/ Repair Permissions. If that doesn't fix the problem, try running the OS X Update Combo 10.4.7 (Intel) (using Disk Utility to expand that .dmg file after downloading).

Problems with ecrypted disk image

I'm trying to restore my laptop (Titanium DVI) from an encrypted disk image, and am having no luck. I have my laptop in target disk mode hooked up to a Mac Pro with the backup disk image.
When I use Disk Utility and attempt a restore, it prompts me for the disk image password, and it starts copying (and apparently succeeds in copying some items). But then after only a few seconds, it prompts me for the disk image password again, and I enter it again, and then I get an error 2, no such file or directory and it dies. After this subsequent attempts without rebooting result in error 16, Resource busy. Finder shows no disks mounted, but a ls of /Volumes shows that there are in fact copies mounted there. unmounting them from the command line does not clear the resource busy problem, but rebooting does.
I thought maybe the encryption is confusing things -- support for this seems sketchy. There seems to be no provision with command-line asr to deal with encrypted disk images. Also, hdiutil can do some things, but for instance I can't use convert to read the old disk image and create a new one, because it tries to apply the -stdinpass option to the new image, not the old one. I'd like to try making an unencrypted image to see if that is causing the problem.
edited to add that I'm doing an erase restore.

You choice. Since the immediate problem's was solved, you might want to start a new thread on the diskutil issue in the Unix forum: http://discussions.apple.com/forum.jspa?forumID=735 and start a new one in the Using Mac OS X Tiger forum on any Disk Utility issues.

I updated to Tiger 10.4.11 & cannot mount disk images &other problems.HELP!

I just updated to Tiger 10.4.11/combo update. I used the stand alone installer (because Software Update since I updated to 10.4.10delta). I repaired permissions before and after the update. Now I can't mount disk images I always get the message "Mount Failed".This occured when downloading and trying to open an existing disk image.I ran fsck, even tried AppleJack all to no avail.I know this problem wasn't there before the update as I downloaded the update and a couple of small utilities and all was well with the world (they all mounted properly). I was doing fine with OSX 10.4.9 but just had to upgrade! Can someone PLEASE HELP ME? I'M grateful for any suggestions and the forums have been good to me in the past.

Some part of the OS is messed up... I've heard that if you Deltas you must stick with those, if you do Combos you must stick with those, no idea if it's true, as I always use the bigger Combo Updates.
Most likely the best solution for both of you is an Archive & Install...

General Installation/ Mounted disk images

I am a Mac virgin, having only had my new iMac for 2 weeks. I have recently downloaded/installed some apps (google earth for instance) and notice that if I eject the mounted disk image that the app will no longer run. I can not "hide" the mounted disk in the HD either. It just sits there on my desktop.
Is there no way to rid my desktop of all this clutter? If anything, is there anyway to hide the icons on my desktop like you could on...<ughhh> XP <ughhh>?
Thanks for your help.

What you need to do is quit Google Earth, open the Applications folder (with Finder in front, click the "Go" menu then "Applications") and drag the application into the Applications folder. After it copies, eject the installer diskimage and you can delete it.
Some installers run a program that installs the app and its support files, and others (like Google Earth) just open the diskimage package and show you the application icon, which makes it all to easy to just doubleclick to run. Since diskimages cannot be ejected while files are open, things get messy real fast.
It's a common problem with even experienced Mac users that they continue to run several apps from the diskimage or from their desktop. Hopefully the Leopard version will have this problem fixed.

10.4.9 and mounting disk images.

I just recently installed 10.4.9 and now I can't mount any disk images. I get an error saying broken pipe. Any ideas? Thanks in advance.

I just recently installed 10.4.9 and now I can't
mount any disk images. I get an error saying broken
pipe. Any ideas? Thanks in advance.
Here's what MacFixit says :
Disk images not mounting [Updated] Several users report an inability mount disk images after applying the Mac OS X 10.4.9 update.
If you are having a problem where disk images won't mount, try booting in Safe Mode (by holding down the Shift key while starting up), then re-attempting mounting of the disk image.
This solution is particularly useful for the following scenario: You want to try re-application of the Mac OS X combo updater (a common workaround for issues that occur after an incremental Mac OS X update), but are unable to mount the combo updater disk image.
Prior to booting in safe mode, however, you can delete the following files:
* /System/Library/Extensions.kextcache
* /System/Library/com.apple.kernelcaches
and re-attempting the mount. These, and other cache files, are automatically deleted when you boot in safe mode, but you can potentially save some time by trying deletion of these files (then logging out and back in) first.
Another option is to use an alternative tool that can mount disk images, like Mount.app, FlashMount, or Toast Titanium.
MacFixIt reader Joy Denton is one user who had success with our posted workaround:
"Just wanted to let you know that I had the issue of Disk Images not mounting. This occurred after installing Mac OS X 10.4.9 from Software Update. Fortunately, I read your post regarding a possible fix by using the Combo Update and used Toast to mount the disk image. Ran the Combo Update and ran AppleJack once again. I am now able to mount disk images. This was an annoying problem to be sure."
But imho the best advice that can be given about software updates is to always have a clone of your system on another partition or external HD so you can boot on it if anything goes wrong. From an external system you can repair your internal disk, install the Combo update if the incremental one failed, etc.

Can't mount disk image error message for TC

After a couple of frustrating days trying to get a back-up to my TC to work (time wasted waiting for the process to fail each time - Can't mount disk image error type messages etc) I finally got onto this forum and find quite a few people sharing my problem! I wont wait as long next time I have a problem to enter the discussions, tho I must admit I don't get many problems with my Apple gear.
There doesn't appear to be a solution in the threads, but at least I am not alone!
How long before and will Apple fix this?

DiskImageMounter.app is in /System/Library/CoreServices/.

How to make mounted disk image appear in sidebar

Hi all,
Previously, I had inadvertently dragged the icon for a mounted disk image off the sidebar. It made the cool "poof" thing. I then checked if it was really unmounted using disk image. It was not, so I unmounted it there.
Subsequently, when I would mount that disk image, the icon would not appear in the sidebar. If you run into this problem, you can fix it thus:
1) Go to the Go --> Go to Folder menu item in the Finder.
2) Enter /Volumes
3) Drag the icon of the mounted disk image to the disk part of the sidebar
You will need to aim properly to get access to the sidebar without activating one of the disk icons.
4) All better
This started out as a question, but I fixed it and thought someone else could use the info.

Nicely done Scott, thanks!

AFP does not allow to access mounted disk-image on server

I am running a Mac Mini as file and media server.
With Lion installed, it was possible to access mounted image files on the server via afp.
Since I upgraded my MacBook Air and the mac mini to Mountain Lion the mounted disk-image is not anymore available as a network drive when accessing the server.
I figured out that I could still access the mounted image file by accessing the server via SMB. This requires however to connect to the server via CMD K, which is more inconvenient than to just click on the server in the finder sidebar.
It seems that Apple changed the AFP setup for Mountain Lion and that this is an error.
Hope they get it quickly fixed in 10.8.1!

I can't even see my mounted images via SMB... that *****!

Invisible Mounted Disk Image

I have a disk image that is encrypted. In opens and mounts as expected on a machine running 10.3.9.
That same disk image when I attempt to open it on another machine running 10.4.9; prompts for the
password and appears to mount however it's not visible in the Finder! When I use a utility to "show invisible files"
it still doesn't appear. If I go to DiskUtility, the volume shows as mounted. It appears with a ls /Volume command in
Terminal. If it didn't appear on another machine I'd say the disk image was damaged or corrupt but it's only on the
10.4.9 machine that it doesn't show. Tried a clean "safe" user account - same results.
I've run all the Maintenance and Disk repairs, Re-did the 10.4.9 (combo) update, DiskWarrior, Drive Genius, etc on
both the Mounted disk image and the 10.4.9 machine.
I've also trashed: Finder Prefs, Extensions.kextcache, Extensions.mkext and
Com.apple.LaunchServices.plist.
Anyone? Any ideas?
G5 Mac OS X (10.4.9)

Even though the disk image did not appear in a "safe user" account, today I
logged in Root and low and behold the image mounted (as it had been) but
this time it was visible appearing on the desktop. I went and changed the
permissions on the mounted disk image to ignore permissions on this
volume. Logged back in my normal user account, entered the pw and it
appeared! The odd thing is have no idea as to how the permissions could
of previously been changed on an unmounted - encrypted disk image.

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
               BLOB blob=null;
          rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
          while (rset.next())
               blob=((OracleResultSet)rset).getBLOB(2);
          response.reset();
          response.setContentType("image/jpeg");
          response.addHeader("Content-Disposition","filename=42.jpeg");
                ServletOutputStream ostr=response.getOutputStream();
               InputStream istr=blob.getBinaryStream(1L);
                int size=blob.getBufferSize();
          int len=-1;
                byte[] buff = new byte[size];
                     while ((len=istr.read( buff ))!=-1 ) {
               ostr.write(buff,0,len);
         response.flushBuffer();
         ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

DW CS3 problem with PNG-8 images in Design View?

DW CS3 (build 3481) on XP seems to have problems with PNG-8 images, specifically trying to display them in design view.
I had a very simple image that was able to be exported by Fireworks CS4 as PNG-8 using 4 colors (no transparency) for a tiny file size under 250 bytes.
DW could not display it at all, or even recognize it, reporting it was 0 x 0 in size. I published the page anyway, and it looked fine in the browser.
I upped the number of colors to 32, and DW could then display it in design view in the page I was working on.
I'm still having problems with other PNG-8 images. The attached file "temp.jpg" is a screenshot showing part of the design view in DW.
The smaller image on the left of the banner is "58_certificate_of_discharge.png" (attached), and the larger image below is used as the background of the DIV containing the form,"compassbk.png" (also attached).
These images all look fine in the browser, but terrible in DW.
I'm stumped as to why.
Thanks in advance.

According to a different discussion, the images that are stuck as "Queued" are showing a bug in the virus scanning on the forums.
Now trying the recommended 'camera icon' method...
Looks like it worked.
Now compare what it looks like in DW CS3 in the design view:
It's a 16 color PNG-8 made in Fireworks CS4 with no transparency, size is 113 x 58, ending up at 1.71K.
If this is a repeatable problem in CS3, is there any hope of it being resolved, or am I stuck with upgrading to CS4 as my only option (assuming it's fixed in CS4)?
Thanks.

Does Time Machine still ignore mounted disk images? Specifically, encrypted sparse bundle disk images?

My Time Machine backs up to Time Capsule which cannot be encrypted. I also have confidential data in an encrypted sparse bundle disk image in my home folder. When TM backs up and the encrypted sparse bundle disk image is mounted and I'm accessing the data, does TM back up the data "in the clear" decrypted form or does it exclude the disk image because it's mounted? I've done a little research, but there's conflicting information. Not sure what happens in Lion now...

Time Machine does not backup mounted disk images! The encrypted sparse bundle disk image was mounted, I updated a doc and did a TM backup - the file was not listed in the TM repository and the doc remained unchanged in the encrypted sparse bundle disk image on TM. Then I ejected the disk image and did a TM backup - the updated doc was backed up in the encrypted sparse bundle disk image! Thank you!

How to make iMovie 09 recognize a mounted disk image?

I'm trying to store video clips in a disk image (Mac OS Extended - Journaled, single Apple Partition Map). Previously in iMovie 08 all I had to do was mount the image, start iMovie and it would recognize it as an additional drive. Then I could drag events to it and store them there. In 09 this does not work. It sees the image but has the yellow triangle/exclamation point in it. I cannot for the life of me figure out how to make it recognize the image! I've tried all variations in disk utility to create the image to no avail. Is iMovie 09 looking for a certain file on the disk image to recognize it? Maybe something in the DS_Store file or the .localized? Very frustrating.
Hoping someone can help. Thanks.

Hopefully that will enable Spotlght indexing on the mounted image. It might take some time to complete depending on the contents.
The result for this for me, three times, was "Indexing disabled."

Auto opening a mounted disk image

Is it possible to make a (read/write) disk image once it has been mounted to
automatically open up and show the folder contents?
I can get this to work if I lock the image, but this makes it a pain to trash.
