PowerPC :: Cannot Open / Unmount DMG Files
Apr 23, 2008
A few months ago my cdrom started not wishing to eject my cd stating it's in use (when it isn't). It shows up on my desktop fine, but won't eject. I have to restart and hold down the trackpad button for it to release the cd. That was all fine and dandy and though annoying I can deal with it...however... My computer is not allowing me to open up .dmg files. I have stuffit...I have the standard diskmount that is default in mac computers but when I tried to download firefox and another program they put a .dmg file on my computer but neither will open up and unmount! So why would a download not unmount...nothing for a .dmg is unmounting on my computer. I tried opening stuffit and it appears like it'll open but doesn't...stays in finder just like when I try to unmount the files. Now that I have the .dmg on my computer I want to delete them because if I can't unmount them they're of no use to me. However, my trash won't let me saying they're in use.

So so annoyed right now. Today my 12" G4 powerbook started to become slow, lots of spinning wheel, delayed menus etc. I checked file permissions, rebooted and it just kept on getting slower. Eventually it wouldn't get past the white apple screen.
I booted off the Tiger DVD and ran disk utility to fix and repair permissions again. It wouldn't let me repair the disk as I kept getting this error:
'Repair volume failed with error could not unmount disk'
I had to reboot again, and eventually my hard disk no longer appears in Disk Utility. I tried to boot into safe mode and get this:
'"I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus"
So now I pretty much can't do anything with it. Failed Hard Drive?

Why when I open an app (i.e. Word) some of the files I previously worked on also load/open? How do I prevent this from happening?

When I try to format my Western Digital "MyBook" external drive, I get an error. It says "could not unmount the disk." What does this mean, and how do I fix it? Also, what's the difference between Mac OS Extended (Journaled) and not journaled?

I have a 15" MacBook Pro on my hands with some sort of HDD issue. The machine suddenly stopped booting and so my first thought was that the HDD has failed or that the filesystem had become corrupt. My files were all backed up, so I went ahead with a reformat and reinstallation of Lion. At firat Verify Disk, run from the Lion boot disk, reported numerous errors that Repair Disk couldn't fix. Fair enough. I swapped the old drive out for a new one that I knew to be good. (And, in the meantime, reformatted the old drive while attached externally to another machine without issues -- so maybe there's nothing wrong with this drive after all?) But no dice this way either: Lion reinstallation fails with an uninormative error message ("An error occurred while preparing the installation."). And if I attempt to alter the partition structure of either drive (either the known-good drive, or the original drive) or to erase the drive, I am told that the partition could not be unmounted. I find this odd, since I have booted off the Lion install DVD, not the HDD in question.
So, I'm left to conclude that something is faulty. I think I can rule out the drive itself -- I have two drives that exhibit the same symptoms, both of which behave fine in another MacBook Pro. I also think I can rule out the SATA controller/logic board since there are no evident IO problems with the DVD drive and, other than the HDD issues, I can run the Lion installer (as well as an Uuntu LiveCD) without difficulty. So what's left? Could it be the SATA cable?

My external hard drives simply refuses to eject/un-mount, and I've done everything I can think of to terminate any processes and/or applications that may be using the drive and preventing it from being ejected properly, but I haven't had any success. Is there some Mac-Jedi way of going about isolating what might be preventing this drive from ejecting properly? I've scoured the activity monitor but can't figure out what might be preventing the drive from ejecting?

I have a 2.5" hard drive connected via USB to my MacBook that keeps unmounting itself. This happens under some (what seems to be) undetermined amount of time, the drive will all of a sudden unmount itself and disappear from the Finder, Disk Utility, et al.
Is there some fix, setting or work around for this? Very annoying. If not, is there a way to re-mount the hard drive without turning it off then on or reconnecting the USB cable?

My Mac Pro [with 4 internal disks, 2 External Disks (Sata Raid 0), and several external FireWire disks and a Voyager disk station] has a little problem with letting externals go Since a few weeks I have a problem with unmounting my externals. After unmount, the unmounted disk will mount again immediately.No time to disconnect cables and/or power. Hinders disk management, backup, and simple disconnecting disks. It only happens with disks (FireWire 400/800/ SATA and USB alike). USB sticks work fine.

I want to carbon copy my bootable external drive to my main internal bootable hard drive so I tried to use Disk Utility to erase it but it will indicate that it failed and can't unmount. When I tried to manually unmount by dragging it to the trash it indicated that it is in use. I can't understand why it's in use since I booted from the external drive which I wanted to the copy to the internal drive.

I want to plug in my computer into my USB dock, automatically mount my external HD, have TimeMachine do its thing automatically (so far, so good), but then immediately after the backup finishes, I want the computer to automatically unmount the HD. This will allow me to close the laptop and go somewhere without having to constantly eject the HD everytime I unplug the computer.
So - what I need is a program / script / etc that will tell the computer to eject the drive as soon as TimeMachine is done backing up.

Whenever I unmount something it remains on the desktop and sidebar, yet isn't actually there if I try to double click on them. So, it unmounts them, but still says they're there. And the remain so until I restart I assume. CDs/DVDs/DMGs and all. Probably should add, when I go to unmount them the first time, I get "An unexpected error occurred (error code -36)

I just bought a Seagate Expansion drive, and it has no power button so when it has been plugged in and not in use for a while it unmounts, and then a minute or two later it auto mounts, is there any way to stop it from unmounting and automounting automatically? I would like to control it myself if its possible (id also prefer not to pull the plug each time i want to shut it off).

I am trying to reinstall Lion on my macbook pro, but every time the hdd shows up as 'locked' and when I attempt to format it, it gives me a "volume erase failed with the error - cannot unmount disk" message. It appears as if some files withing the disk are still running but I have no way of quitting them-knowingly. I can specify more if this seems to vague.

I have a Macbook pro 17" (2011) running Mavericks with a Crucial 960Gb SSD and a 750Gb WDC in the optical bay. My ssd is divided into 710 Gb to OS X and 182 Gb to Windows 7 Bootcamp. All was well until the other day when the OS X partition failed to boot. I got the grey screen and the very slow progress bar which after 15 minutes powered the machine off. The Bootcamp partion continues to work without issues. I booted from an install disk and ran disk utility. The OS X partition appears greyed out on the left panel. I attempt a repair disk and after a 15 minute delay it says it is unable to repair the last action being "updating boot support partitions for the volume as required". Its all backed up regularly on time machine but when I boot an install usb and attempt to restore from time machine, the OSX disk does not appear as an option. I go back into disk utility and attemp to erase/repartition the disk to start a new install but it refuses to unmount. I appear to be running out of options,

I have a Western Digital 500gb external hard drive, with 2 partitions, 'KAINARC' and 'JUNGLEMAC', connected to my Intelmac (Tiger 10.4.11 via my firewire, i have connected via usb but the problem is still the same). I may have shut down the drive improperly to cause this situation.
KAINARC now appears on my desktop, but the partition of JUNGLEMAC does not. I go to disk utility and both partitions are visable, KAINARC is mounted but JUNGLEMAC is not. I cannot mount JUNGLEMAC.
When i try to verify and repair the partition I get the message:
Verify and Repair disk �JUNGLEMAC�
Error: The underlying task reported failure on exit
1 non HFS volume checked
1 volume could not be repaired because of an error
So I try to verify and repair the partition KAINARC but get this message:
Verify and Repair disk �KAINARC�
Repairing disk failed with error Could not unmount disk
So I have opened diskwarrior (unbelievably long time to start up and scan disks) in the hope of fixing the hard drive, but when i try to repair I get the error message 'unable to unmount KAINARC'.
I have tried other repair/recover programs but get the same message: 'Could not unmount disk KAINARC'. Im asuming that to fix the hard drive it has to be able to unmount KAINARC.

I replaced a 1 TB external drive partiotioned in 2 with a 3 TB extrnal drive run/store my corbon copy cloner back up and time machine.
The 3 TB drive was successfully partitioned through the disk utility and both back ups are installed and the initial back up is complete.
My question is about the 1 TB drive. I want to completely erase all data from the drive in order to use it for a different use.
Using disk utility one of the partitions deleted without incident when following the same protocol the second partition produced error messages.
Volume erase failed
Volume Erase failed with the error:
Couldn’t unmount disk.
If I try to eject the disk
It says it will not eject becaus e a program may be using it...
The only program that utilized this partition is Carbon Copy Cloner which is not being utilized on the new 3TB drive.
I do not see where there is a option to have more than on disk chosen for this purpose so am unsure why the disk utility is seeing the old partion as still in use.

I have a MacBook Pro running OSx 10.9.4 and have been successfully using Time Machine with a WD My Passport External Hard Drive for a while. Now (after 10 days with a successful back-up), the computer will not back-up. I have gone into disk utility and tried to erase, partition, and/or repair the disk, but repeatedly get error messages - it can't erase the disk, re-partition the disk or unmount the disk.

I accidentally slid the Hard Drive in the top bay of my Powermac G5 ini upside down. After sliding the bottom one in right side up I and then realizing what I've done, I'm not able to pull the bottom one out to fix the problem. Does anyone know how I might get the casing that holds the hard drives in out of the tower so I can get the hard drives out?

I have just rebuilt a G4 MDD. Works great, except for one thing.I cannot get the Cd drive to open!!
Pressing the eject button on the kyb doesnt do it. The eject button on the actual drive is covered by the plastic tab of the mirror metal.
The new Itunes doesnt have an eject button that I can see, either.I dont see any "eject disk" button in any of the utilities.

I have a dual 1.8 PPC G5 power mac that I bought used about a year ago. It came with OS 10.5 preloaded but the only discs I have for it are the original system disks(10.3). I've got it hooked up to a HP 19 LCD via DVI. The other day I tried to boot into open firmware using the command-option-O-F start up command. Well, something happened cause OS X never came up, but nothing else did either. The screen just stayed blank, the fans starting ramping up and just got gradually louder and louder. I tried entering mac-boot via the keyboard thinking that maybe I was in OF even though I couldn't see anything on screen, but nothing changed.
