DMG won't unmount

Please, I need your precious help.
I mounted a DMG as usual, copied the application and then I tried to unmount the DMG.
It says that the DMG can't be unmounted because is using a file or a document.
I checked and everything is closed.
I tried a reboot and the DMG is still here.
I tried to unmount it through Disk Utility, same error.
Please, I don't know what to do. Is there any command to try a forced unmount of the DMG?
Thanks a lot.

I managed to resolve it. Don't ask me how because I don't know XD Thanks anyway.

External hard drive won't unmount for disk utility.

Im not sure if this is the right topic area but I have a white macbook and my external hard drive won't unmount. I want to erase it via disk utility but it keeps telling me other programs are using it.

Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.

Lacie won't unmount

Greetings Gurus,
I took part of my system home to do some work over the holidays and am now having trouble unmounting my Lacie BigDiskExtremeTriple. This drive has always been connected to my Dual G5 desktop (profile listed below), but I'd hoped to get some work done on the MBPro 17.
Here's what info I have so far:
I believe the problem started from having several external FW drives looped through a Belkin FW hub (sorry, no specs on it right now other than 3 FW 6pin ports on each side of the hub) - computer froze and I had to reboot.
I believe this caused some possible directory damage to the Lacie since I had been unable to 'unmount' the drive properly.
Support and Google searches have offered several things to try, but none have resolved the issue yet. Most suggest a 'directory issue with the drive' that Disk Warrior may fix. I have DW3.0, but also read that it's not going to work if the drive won't unmount in Disk Utility (which it wont')
Here is what I've tried so far.
any usage of Finder/Spotlight locks up the system.
Drive seems to work, though I've delayed pushing it with apps (mostly FCStudio), until I can resolve the issue.
Force Quit Finder - have been able to then unmount the drive once or twice, but usually not.
Restart Mac - can usually then unmount the drive, but not always
Check Activity monitor - this shows a Process ID/Name 'mds' at Root level running 99% (any ideas there?)
Run Terminal commmand 'sudo lsof | grep "The-Volume-Name"
- This gives me 4 items (one at Finder and 3 at mds) - Here is what it listed...
Finder 98 kevandholdsworth 19r VDIR 14,11 68 10944 /Volumes/MEDIA/.Trashes/501
mds 186 root 22u VREG 14,11 1069056 4392 /Volumes/MEDIA/.Spotlight-V100/store.db
mds 186 root 23u VREG 14,11 1069056 4393 /Volumes/MEDIA/.Spotlight-V100/.store.db
mds 186 root 24u VREG 14,11 0 4395 /Volumes/MEDIA/.Spotlight-V100/.journalHistoryLog
Is it possible to just locate these files and delete them? or will DW need to do it's own thing?
I'm ready to try Disk Warrior, but would appreciate any feedback regarding the issue before I attempt it.
(sadly, I broke the cardinal rule of not double posting [initially in the 'Finder, Dock & Dashboard Forum], but feel much more confident of getting strong advice here...my apolgies to any I've upset by doing so)
Thanks,
Kevan
PS - just checked my profile and it does not yet list the MBP...It's a 17" w/2GB Ram, same OS and Software as on the G5

It's not backed up yet...I'll do that before running DiskWarrior
I'm not convinced what the issue is. I now am unable to unmount any external HDs (all FW) from my G5.
Jim, Disk Utility is not giving me the option to 'disable journaling'.
Spotlight prefs won't let me add(+) either volume to 'privacy'...that's my understanding on how to remove it from being indexed. However, when I tried 'dragging' one of the volumes into the 'privacy' area, it went 'Poof'...now showing up on desktop, but no longer in finder...is this what you are referring to?
Kenneth, I'm the only user/admin...not seeing an issue there. Maybe I'm missing something from your suggestion. I simply boot up as I always do.
UPDATE...
FYI, here is the original prompt I get when trying to unmount any external hard drives: "The disk "DISK NAME" is in use and could not be ejected. Try quitting applications and try again"
There are no visible applications open...I notice now after dragging a volume to spotlight privacy that one of the text lines from the Terminal sudo command no longer shows up.
I have been able to unmount all drives after starting up from a backup drive (Panther). However, restarting from Tiger does not allow this. I'm also a bit concerned about doing restarts without properly unmounting any of these drives.
Here are a couple of links I've been trying to apply, but it's looking like a backup and DiskWarrior are next steps. A show deadline is preventing me from doing so at this time.

RAID won't unmount...can't repair

Problem: after fixed failed RAID (lost in poweroutage), RAID'd drive won't mount. If I drop to single user mode and fsck the boot volume (no errors listed), after reboot it's the RAID volume is back. I loose it after a restart without fsck (boot volume loads but RAID is "unrecognizeable").
When it mounts everything functions as it should (users get home folders and have read/wrote access, etc.). However if I try to repair it in disk utility (per Apple phone support), i get an error message saying that the disk can't unmount so therefore can't check it.
Any suggestions (besides clean install) that you have to keep the RAID volume intact? I refuse to believe that it's toast as i am able to have it function. I guess I wouldn't be opposed to a wipe if I could get a good backup of it, but I can't even do that since it won't unmount.
Can't wait to hear what you come up with!
Thanks in advance.

Really, how toasted can it be when it all works flawlessly
until reboot? THis really bothers me....
Don't get me started about the Apple Hardware RAID card. I hope you have the write caches turned off for all LUNs because they don't always fully flush on graceful power down (the drives are disconnected from the bus before caches are flushed) - I've had a RADAR bug report turned in for almost 2 years on that, it was very hard to track down and create a reproducible test case. LSI Logic fixed the bug in their microcode after Apple split its version from the LSI Logic code tree to modify for use in the Xserve; don't expect this bug to ever be fixed because the product is EOL, only known workaround is to turn off the write caches.
That said, the disks are big. You think it's working flawlessly, but it may not be. Mystery garbage blocks from space, especially on a RAID, can be hard to track down. For example, on a RAID 1, the read data might not always come from the same disk of the mirror.
If you really think that the mirror is good, I'd suggest cloning it off while booted from another disk (perhaps split the mirror, clone - not image - to one of the split disks, then recreate the mirror from the good copy).
Yea, your DiskWarrior issue is because the disk can't be unmounted.

PhotoshopElement_10_WWEFDJ.dmg won't open?? Warning message

I believe my Photoshop Element Trial has downloaded, and is just now extracting, but I got a pop-up warning box that says PhotoshopElement_10_WWEFDJ.dmg won't open. It says it's a disk image and the reason it can't open is "invalid checksum". What does this mean? Is this warning affecting the extraction of my download? And how long should this extraction take?
Thanks!

It is possible that it is still extracting your download. Where did you choose to download the install files too?

Disk images won't unmount/eject for admin user, DVDs & iDisk also affected

This problem started when I was on Tiger, and seemed to follow me onto Leopard.
It only affects me, the primary user on my Mac. *One other user on the computer; she also has admin level access and does not have any of these problems.*
Here's the deal:
*Once mounted, disk images won't eject/unmount.*
- Dragging to the trash can doesn't work. The eject icon appears, but nothing happens.
- Ctrl-click does not show Eject as an option when highlighting the mounted image.
- CMD-E doesn't work
- EJect doesn't appear as an option in the finder menu
- Clicking on the Eject button in the sidebar of the Finder window doesn't work.
- I've logged out, rebooted, repaired permission, and installed a new OS (clean install of 10.5, then did the import of my old user settings. Since I had the problem in Tiger, it's clear the problem followed me, but what the heck causes it?)
*The only way to unmount/eject a disk image is to use the Disk Utility Program.*
*DVDs also can only be ejected via Disk Utility*
The iDisk connection can only be killed by opening Activity Monitor and killing the webdavfs_agent process.
Would love some help. I've searched a lot and have a fair amount of folks with this problem, but no real solution.

That'll work; however, then the OP has to reset all of his preferences. Easier would be to log into the newly created admin account, backup the bad account's folder, delete the bad account, selecting the save data option (which is stored in /Users/Deleted Users/ as a disk image), recreate the bad account using the same username/password combo, log out and back into the recreated original account. Mount the saved data dmg file in /Users/Deleted Users/, open the /Library/Preferences/ folder from the saved data, open the current /Users/restored account/Library/Preferences/ folder, and slowly copy plist files from the saved data folder to the current one. Log out and back in to ensure there's no conflict and things still work correctly. Resolving these kinds of conflicts is a laborious process, but not as laborious as resetting preferences or even remembering what you set weeks, months, or years ago.

Do you have QuickTime installed? If not, install it or Repair it.
To Repair, START/CONTROL PANEL/PROGRAM n FEATURES/highlight QUICKTIME and click REPAIR.
Another thing to check is see whether your system is clear of Malware but you have to SCAN it in a SAFE Mode:
Start your computer in "Safe mode with networking", go to CNET's download.com to download a free version of Malwarebyte. Install and perform update immediately, then do a full SCAN. Remove malware if it indeed finds any. Restart computer to regular windows to let Malwarebyte complete the removal.
To start your computer in safe mode
Restart computer
Press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
On the Advanced Boot Options screen, use the arrow keys to highlight the "safe mode with networking" option, and then press Enter.
Log on to your computer with a user account that has administrator rights.
When your computer is in safe mode, you'll see the words Safe Mode in the corners of your screen. To exit safe mode, restart your computer and let Windows start normally.

Suddenly, TC won't unmount

Time Machine has been working flawlessly since I got my TC, but now all of a sudden, the drive will not unmount after finishing a backup like it always has. Any reason why?

As they age they become less reliable..
What kind of modem and broadband are you using??
If it is gen 3 I suspect your TC is suffering from onset of board capacitor issues..
Please give me the A1xxx model number from the rubber mat on the bottom.
Do the setup that you know is correct.
Leave the TC off overnight to completely cool down.. start it up again the next day.. see if it will work.
If you get it working but it fails after a few minutes.. you are suffering A1355 early board failure.
If it doesnt work at all, try to use just wireless.
Set the wan ethernet speed down to 10mbit.
You will not be able to do that using the v6 airport toyland utility.. you need to use 5.6 which can be tricked into working on Mountain Lion.
Simply download the utility.. and unpkg..
http://support.apple.com/kb/DL1482
http://www.timdoug.com/unpkg/
Run unpkg.. click the dmg airport utility and drag the pkg file over unpkg.. it will load it to a new directory on the desktop.. drill down to applications, utilities.. drag it to your utilites directory.. or just run it. Do not run both utilities.. stick to the tool and leave the toys behind.

IDisk won't unmount / eject

Since doing an Erase+Install of Leopard, I've been unable to cleanly eject/unmount my iDisk. Drag it to the trash, the Trash shows the Eject icon, but nothing happens. What I have to do is open Activity Monitor and quit the "webdav" process. Anyone else having this problem?

DMGs Won't Mount!

Hello,
I am downloading iTunes 6 for my PowerMac G4 Cube. The DMG file downloads fine. But it won't mount. When I double click on it to mount it, this comes up:
"The following disk images failed to mount
iTunes6.0_Mac_OSX.dmg - Reason: No mountable file systems.
I have deleted a couple of apps such as Chess, Image Capture and iMovie but I do not believe that this has any effect on this problem.
Thanks!

Hi, the DMG could be corrupted. When it's an extremely large file, sometimes missing a few packets makes the file broken. Have you tried redownloading it several times?

TM disk needs repair but won't unmount.

Hi,
I've been having problems with this TM disk since new but I can't work out what to do. The disk is a Seagate 1.5TB with my MacPro backed up to it and a sparse image on it as my MacBook backup.
The disk only has one volume on it. It has done strange things in the past like return an error on the initial backup of the MacPro after about 900GB of data and when I wiped the drive and tried backing up again it returned an error at about the same stage. Subsequent incremental backups worked so I continued to use it but I have never been able to eject the drive. I have always got the "something is using it" dialog box. I could only safely power it off by restarting the MacPro and turning it off before it booted. I checked the disk in disk utility and it said it needed repair but could not be repaired. After hearing about trouble with these drives I returned it for a replacement. I got an error on the first backup again with the new drive but subsequent incremental backups were OK so I left it. I checked it in disk utility yesterday and it said it needed repair but would not unmount for the repair. I have reset the FW800 port in the past and that didn't seem to make any difference. Other drives in this enclosure (SOHO Tank, Oxford chip) work and unmount OK. I don't know whether this is a TM issue or I've got another flakey drive. I'm tempted to send the drive back to Seagate again as I don't feel secure with this as my backup.
Also, occasionally when I go into TM via the TM icon in the dock, I only see backups up to the day before yesterday in the timeline at the side. If I cancel TM and relaunch I get the full set in the sidebar (yesterday and hourlies for today).
Any thoughts?
Thanks,
Brian

If possible, you should partition the drive, so the MacPro's backups are in their own, exclusive space. If you ever want or have to delete them, it will be extremely difficult and take a very long time. See #4 in the Frequently Asked Questions *User Tip,* also at the top of this forum.
Other drives in this enclosure (SOHO Tank, Oxford chip) work and unmount OK.
Try repairing it from the copy of Disk Utility on your Install disc. (Boot up from it, select your language, then on the next screen select Utilities from the menubar, then +Disk Utility.)+

Disk Utility won't unmount drive

When I boot to a casper image via ethernet I will open disk utility and sometimes I can erase the drive but other times it just keeps erroring out. It says can't unmount disk even though the computer is booted to netboot. Why would this happen its very random. I think all the issues are with the 2012 Macbook Pros other macbooks don't have this problem.

To partition the drive, you'll have to boot from a different one, not from the recovery partition on the same drive. Or you can boot into Internet Recovery by holding down option-R at startup.

ITunes 11 dmg won't open in OS 10.6.8, error -4960

I've found a few other references to this error code, but most are a couple of years old (before iTunes 11), or they're for Windows. Any idea why my Snow Leopard won't open iTunes 11.0.4? Any little tweak I need to make somewhere? thanks.

Hi, pmajor. Welcome to the Adobe user-to-user forums!
I noticed that your error report indicates that you are using build 4909 of Dreamweaver CS5, which is the release version. There have been some updates since, so I would suggest that you install the latest, 11.0.4 (build 4993), and then see if the problem persists.
You can get the latest update by going to Help > Updates in Dreamweaver, or by downloading it from the following page and then installing it: http://adobe.ly/DWUpdates

KDEmod (KDE) device notifier won't unmount devices

I'm using KDEmod 4.4 currently, but this has been happening since 4.3 using plain KDE too. For some reason, when I use the device notifier to mount a flash drive and then try to unmount it, I sometimes get the "Could not unmount the device. One or more files on this device are open within an application" error message. However, I am able to unmount from the command line, so I think it must just be an issue with device notifier.

On my install, whenver I save files to my desktop (KDE 4.3.2) the files don't show up until I rightclick the desktop and click "refresh". The same thing happens when I delete a file. When I delete a file, the file still shows up on my desktop until I rightclick and refresh the desktop.
Whatever KDE uses to monitor when files are deleted and whatnot is not working.
I have the same issue here. I belive it's because of the current kernel. Take a look at this http://bugs.archlinux.org/task/16193?st … &closedto=

Maxtor III won't unmount

Hello All,
I am capturing video to a series of 4 Maxtor III combo drives via firewire 400.
I have set up and used 3 of the drives, the first 2 drives I have mounted and unmounted several times with no problems.
I used the 3rd drive for a couple days and when I went to unmount it it will not eject. I have tried all ways of ejecting and while trying to unmount in Disk Utilities, I received the error message:
The disk “Tung's 3” could not be unmounted.
Make sure that all applications and files are closed on this disk.
I closed all applications and still got the same error message.
When I repaired through Disk Utilities I got the following message:
Verify and Repair disk “Tung's 3”
Repairing disk failed with error Could not unmount disk
I have used the hard drive to capture video only, there are only FCP files on the disk.
Any suggestions? I appreciate it.
Terese

I'm probable confusing the issue because of my lack of computer knowledge.
I do not have all four drives hooked up at once. The Maxtor III is a hot swapable drive and I have one of the drives hooked up at once.
My operating system is 10.4.8
my computer is a G5 imac 1.8 GHz, 768 MB SDRAM
the application version is FCP 5.1
the camcorder used for capture is a Sony DCR-HC26.
I have the camcorder and one of the drives connected via firewire.
I hope this answers the questions, I appreciate you helping me sort it out.
