Cannot Unmount Internal HD

Hi Guys,
I had a problem booting my computer up a while ago (it would just sit at the white apple screen with the loading wheel) so I removed the internal HDD and backed it up to my desktop computer using a USB adapter hub. I then completely erased the drive. I followed multiple forums on how to create a bootable USB flash drive with Lion, so I did so. I then booted up my computer while holding the Option key, and selected the flash drive (which had the OSX Lion Installer App on it from the mounted installESD.dmg file).
I'm now stuck yet again trying to reinstall Lion on my hard drive. I am in disk utility, and I cannot unmount my internal drive, which means I cannot reinstall lion to it. When I run the reinstaller it tells me that there was an error, and I need to reboot the app, which does nothing.
What i would really love to do is completely erase my internal hard drive (even though I thought it was already) and install Lion onto it from the bootable USB flash drive.
I have an '09 MacBook Pro. I've gone to SmallDog twice with my laptop and they told me that they cannot do anything or that I should do it myself to save money.
And help would be greatly appriciated. Thank you!!

There should be a simple explanation. Many background programs on your Mac, including Spotlight, access files on all formatted volumes connected to the computer; most of these programs are designed to allow an in-use volume to be unmounted without causing issue, but one notorious counterexample is the iTunesHelper background process. iTunesHelper coordinates iTunes' interactions with the rest of your computer, and may be using files on your iMac's hard disk, preventing you from unmounting the volume.
If iTunesHelper is running in the background, it's probably causing your issue, so you can just kill it (quit) from Activity Monitor. Search Spotlight for it, or open your /Applications/Utilities folder - you should see Activity Monitor near the top of the list. In the list of processes you see, find and select iTunesHelper and click the "Quit Process" button up top.
Now try running Drive Genius's Defrag again. It should be able to unmount your internal drive and run the repair normally. Just remember to leave your iMac alone while it's defragging! You don't want to accidentally interrupt the process.

HT1526 I'm trying to delete files from the trash and an .InProgress file in Time Machine that cannot be moved to the trash. I cannot unmount the TM disk either. If I use the chflags -R nouchg command, I get a "Resource busy" message. Any suggestions?

I've got one or maybe two problems. Time Machine routinely crashes and there is a file in the TM folder that is an .InProgress file at the end of successful backups. Can't delete it, even using various sudo commands in Terminal. These come back with a "Resource busy" message.
Similarly, there is a Microsoft Office alias in my trash that will not delete, again including various delete or Terminal commands. Also "Resource busy"
I can't reformat the TM volume since it cannot unmount and it also cannot unmount the whole disk, which contains some other backup files I'd rather keep.
Any suggestions?

I'm not sure I can be very helpful since I was doing a lot of things and ultimately the problems went away. But one thing that definitely seemed to help was to shut down, restart, do something, shut down again and repeat. So with a clean start, try to move the file to the trash. If that works, shut down restart and look to see if it is still in the trash. Empty the trash. Shut down if it appears to empty and then restart. It seemed sometimes that the computer was doing what I wanted then something was overriding this and restoring. The shutdowns immedately after I could do something but before it engaged an override operation seemed to keep this from happening.
Sorry to not have more to offer but...

Disk Util cannot unmount ext HD to format or partition

Computer: MacBook Pro Retina 13" latest model. All updates have been applied.
I have a 1TB WD external harddrive. It has 2 partitions (1 FAT32, 1 Mac OS Extended). This drive was working properly until one day it stopped mounting.
Problem:
- Mac OS Extended partition: Will not mount. I can see it greyed out in Disk Utility. The entire drive will not unmount.
- FAT32: Mounts in OSX but will not unmount. I can access FAT32 partition via Parallels (Win7).
Bigger Problem: I'm cannot re-format or re-partition the drive. Disk Utility provides an error that the drive cannot unmount.
Any help is greatly appreciated.

I made a mistake in the original post. I CANNOT access the FAT32 via Parallels because it will not unmount from OSX.
This is how I fixed it....
Booted up my Windows laptop and used Computer Management to delete both volumes (partitions).
Re-partitioned as 1 partition (ex-fat) and formatted.
Booted up MacBook and used Disk Utility to re-format as Mac OS Extended.
This appears to work fine, and I am able to use it for Time Machine now.
My question now is: How could I have accomplished this in OSX? I know some people will say maybe the drive is going bad. For this question, let's assume it's ok.

Cannot resize internal disk Disk Utility

I was partitioning my drive but then Disk Utility became stuck, I force quitted it and tried to revert the changes it made. I managed the delete the half created partition but now when I try to extend my boot partition back to its normal size, it doesn't work.
I tried booting into recovery and using Disk Utility, there I was give the error "cannot unmount disk" I tried repairing it. still didn't solve the issue. If I need to restore from timemachine, how will i s

This worked for me: https://help.backblaze.com/entries/22395778-How-to-partition-a-Time-Machine-driv e
Basically, you have to turn off Time Machine automatic backups in System Preferences (and possibly restart Disk Utility) before the drag handle shows up.

[SOLVED!] Cannot select internal/external mounts .......

Greetings,
After being away doing some distro-hopping, I drifted back over to arch. Now I managed to work through many problems such as getting keyboard and mouse support without disabling hotplugging, and all of that, and am enjoying using ext4.
However there are two issues that I can't seem to overcome, and would greatly appreciate any help I can get in overcoming them...
1.) I cannot select internal mounts or usb cards or cd's, etc..
Basically I was trying to be able to mount/access my NTFS partition. At first I was getting that pesky "you can't do this, policy says no" error so I dug through wiki articles and forum posts. After following them (including doing computer restarts) I could not select either my ntfs partition or my mounted dvd disk. Basically what would happen is I would try to select it but my selection would bounce back to my home folder. No errors or nothing. It's like there is an invisible rubber force field preventing me from even thinking about touching those drives.
Now I have tried everything I can think of. I have removed everything I have done when following the wiki to get to a pre-trying to mount ntfs stage. Problem remains. I have dug through the wiki and countless forum posts trying out everything that looks feasible to my problem. Problem remains. I am now on day two, several advil later, and tired of hearing my computer laugh at me.... I really don't want to go through the whole reinstall trip... I already spent a lot of work before trying to mount my ntfs drive getting my computer just how I want it. So any help in fixing this without a reinstall would be most appreciative. I will admit that I am tired of digging through the wiki, so if you must point me back to it, please kindly clarify what I may have missed instead of saying "read this" because 9 out of 10, I have read it and it hasn't helped.
2.) How do I get wicd to auto start?
Ok so I have installed wicd as my network manager. I followed the wiki to the T and it works great. However every time I restart (which I did a lot of trying to fix problem #1) I would end up having to restart the hal and wicd deamons then start up wicd again... So how do I get wicd to autostart?
Thanks in advance for any and all help on these two issues. If I posted in the wrong area, please forgive me. However I feel that these are newbie questions...

Greetings,
I am using KDEMod current (i.e. KDE 4.2.1). I installed the Arch way, not the chakra tribe method, though I did test tribe earlier, it's neat.. just not as hands on...
I tried accessing with dophin. I would have tried with konqueror but as I recall konqueror now uses dolphin as kpart for file management so the results should be the same...
Anyways,
Here's my fstab...

You should notice that I didn't add my ntfs partion to fstab as I read somewhere that with hot plugging you weren't supposed to...
Here's my rc.conf - daemons
# DAEMONS
# Daemons to start at boot-up (in this order)
# - prefix a daemon with a ! to disable it
# - prefix a daemon with a @ to start it up in the background
DAEMONS=(syslog-ng !network wicd netfs crond alsa hal kdm)
If you need the rest of my rc.conf, let me know. However I believe that only the daemons should matter with wicd...
And btw- thanks for your reply.

Error : Item cannot be Internal Ordered if Pick Components is set to Yes

Applied 'PTO Model' template, when Internal Ordered attribute is checked under Order Management Tab along with Pick components I get the error message 'Item cannot be Internal Ordered if Pick Components is set to Yes'. This item should be allowed for internal orders and has components to be picked, please advice.
Thanks,

Refer to OE-ATO: ATO/PTO - FAQ [ID 99861.1]
It says configurations cannot be ordered internally.
But refer to the following note for a work around.

How to install Snow Leopard on Macbook Pro? keep getting msg- cannot install Internal HD is used for Time Machine- this was reset to external HD and still get msg?

How to install Snow Leopard on Macbook Pro? keep getting msg- cannot install Internal HD is used for Time Machine- this was reset to external HD and still get msg?

At some point, your internal HD was selected for use as Time Machine backups, and a Backups.backupdb folder was created at the top level. So OSX thinks you're trying to install it on the same drive as your backups.
Open your internal HD with the Finder (you won't find it via a Spotlight or Finder search) and delete that folder.

Select Disk Utility.
Select the Macintosh HD volume
Click erase, wait till it finishes destroying all your stuff.
Weep cause your Mac won't boot no more.

Cannot unmount volume

I was doing a maintenance on my system yesterday. I used DiskWarrior to do a rebuild on all the volumes. All was okay, except for my Mac HD 5 volume. I got this message when I tried to run DW 3.0.2 on this volume:
Repairing disk for “Mac HD 5”
Repair attempted on 1 volume
0 HFS volumes repaired
1 volume could not be repaired
Repairing disk failed with error Could not unmount disk (-10000)
When I used Disk Utility, verify disk volume, it said all was OK. But when I tried to verify permissions, it stopped about 1/4 of the way through. And then gave me a message "lost connection to volume, cannot unmount". Or to that effect.
I then tried TechTool Pro 4.1.1. I did a disk check, and all was okay. But when I tried to do a Volume check, I got this message from TTP:

TTP didn't actually complete a volume check. I hit start volume check. And it would just indicate it was complete, without actually every doing a full check.
Hopefully, there is a way of fixing this, without have to reformat the volume.
Also, I cannot startup from this volume. Tried, just got the grey Apple screen.
Thanks in advance.
G4 AGP 1.2Ghz upgrade, 896MB ram, LaCie DVD RW Mac OS X (10.3.9) StarTech USB 2.0 card, 30GB, 80GB, 120GB HDs

Thanks dot. But I figured it out already. The problem was that the "automount volume folder" was deleted from the Mac HD 5 volume (have no idea how). These are invisible files, so I used Tinkertool to make them visible. That's how I realized that the automount file was missing. All the other volumes contained automount files for ALL the volumes (including for Mac HD 5). Except for Mac HD 5. This volume was missing it's own automount file. So I just copied the file over from one of the other volumes. And voila, Mac HD 5 is now bootable, and can be unmounted for volume maintenance.
Everything is working as it was.

Cannot unmount encrypted sparesbundle

Hi,
Upgraded from Snow Leopard to Lion and now each time I mount an encrypted sparesbundle and try to unmount it I get the following log:

The bottom line is that I cannot unmount the sparesbundle. Each time I try to unmount it, it does so and the system mounts the image again.
It even mounts itself on logon (even though it's not present in the login items).
The "/var/db/fv_secure_erase.jobs" file / directory indeed is not there.
Any ideas what might be wrong?

Unfortunately, I also have the same problem in Lion, at random.
Not having enough space on my MacBook Pro drive I have my iPhoto library in an encrypted sparsebundle on an external USB. After I have done work in iPhoto,
SOMETIMES, selecting the mounted sparseimage and the USB external drive containing and using Command-E to eject them together works fine and other times it leads to a stuck unmount.... Spotlight may also be part of the problem: Console shows:

Attempt to restore from Time Machine back-up failed - cannot 'see' internal HD to restore to. Help! Has attempt to install ML caused these problems or just highlighted existing need to Repair Disk? Even so, why can back-up from Time Machine not see the internal drive to restore to?

Csound1, William & Sig .... thanks for taking the trouble to reply. I fear you are right - I'll need a new disk. I'm booked in at the Apple Genius Bar in Bordeaux, France on Wed ... quite a challenge as my French isn't great! The current internal disk is 500gb, does anyone know whether I can upgrade my 21.5" iMac (circa Oct-2009 vintage) to a larger size internal disk, 1Tb or even 2Tb? I already have one external 2Tb drive and another one on order (I have masses of media stored and more planned as I've just taken up photography). Seems a bit of a pain managing with only 500gb internal storage. OR, can you advise me on how I can store all my photos on my new 2Tb external drive - I can't seem to figure out how to set the path for iPhoto to see them (I can't even figure out where they are stored right now!). Same with iTunes, how do I set the default storage to the external drive (I moved everything manually and then imported them all from the new drive - it worked but seemed very convoluted). Any advice on how to manage multiple drives gratefully received. And thanks again for previous replies.

Self-service users can mount iso but cannot unmount

I have 3 tenant groups that can mount iso files to vms located in their clouds (via App Controller 2012 SP1) from a library share but cannot unmount them. Actions granted to them are: Deploy, Deploy (from template only), local administrator,
remote connection, shut down, start, and stop.
The library share was originally shared on the server to everyone as read, adminstrators as full control.

Ok this is not a great solution IMHO. I believe this functionality needs to be split out.
The solution for me was granting Deploy (from template), local admin, remote connection, remove, shut down, start, and stop. Deploy allows mounting of the iso and remove allows unmounting. Remove also allows vms to be deleted if they are off!!!
I can see the thinking here...self-service tenants with the capability to deploy new vms should also be able to remove them (within their tenant group and fabric space). However, one size does NOT fit all. These functions need to be split out for
additional fine grain control.
ex: I would love to allow certain application personnel to mount ISOs but NOT to delete vms.

Problems Restoring Erasing Drive: Cannot Unmount Disk

I just intalled an SSD in my macbook pro, and would like to use my old hard drive as a storage disk. When i boot into the ssd (mountian lion) and try to erase the old disk it says it cannot unmount the disk. i have also tried booting off an external disk (also mountain lion) and i get the same problem. Any ideas would be greatly apprectiated.

Sometimes when DU can't unmount a drive or volume it's because something else like Spotlight or TimeMachne has it in use. Set your Spotlight to ignore the drive.
Also try using command r booting into Recovery for Disk Utlity there, it doesn't have Spotlight, TM or anything like that so it should unmount the drive.
If your still having problems and you don't care about the data on the drive, then you can try buring a disk of Parted Magic ISO and see if you can option key or c key boot off of it and go hog wild messing up the drive's data and boot flags.
Once that's done use Recvoery to Secure Erase (middle selection) and that will take care of it, then format GUID OS X extended journaled, GUID or MBR + exFAT or whatever.

Error "cannot unmount disk"

I tried to erase+ reformat my Seagate HD for Macs but got the error "cannot unmount disk." Does anyone know what this means and how to fix it?
Thanks in advance.

In Terminal use the umount command. You will need to know the identifier of the disk you're trying to unmount. The command will look something like 'umount /dev/disk1'.
