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.

Wd My passport won't show up on macbook

I recently got a new external hard drive for school, it is a 1tb My passport WD. It seems to work fine I just can't find it any where on my macbook. I have checked disk utility and there is nothing there, I have even plugged it into a windows os and it worked fine, I could access it and everything. But whenever I plug it back into any mac/macbook it won't show up. I would rather not go through the trouble af sending it back and looking for a new one, please help.

tried it on with other computers and change cables! and still, it wouldn't show!
What other computers have you tried it on? Mac's or PC's?
Take the WD HDD out of it's enclosure and insert it in another one (non WD). Connect it to your MBP. What is the result?
Ciao.

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.

Disk Won't Unmount in Disk Utility

I have a WD Passport external hard drive. When I plug it into my macbook pro via USB it does not show up so I went to disk utility to erase and re-format the hard drive as this has fixed the same issue in the past. However, when I try to erase the external hard drive in disk utility I get an error message stating that the disk cannot be unmounted. Please advise on steps I can take to fix this issue such that I can erase + re-format the hard drive so it will show up in my finder again. Thanks for the help.

You could try using diskutil. This is a command line utility to manage your mounted disks:
http://osxdaily.com/2013/05/13/mount-unmount-drives-from-the-command-line-in-mac -os-x/
be sure to close all other applications before trying to unmount as if they're accessing the disk it will be considered busy.
there is also a force option you can use as a last ditch attempt.

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.

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.

External WD Passport won't recognize after Time Machine start.

I bought a WD passport 500 gb drive and when I initially plugged it in time machine saw it and when I asked it to use it- something happened and now NO icon appears in order to be selected nor does an icon show anywhere to even select. I changed the drive and the new one does the same. Cycles continously and never mounts. Did the usual- changed ports and changed wires. It just isn't recognized no matter what. What to do?

jimmyb12015 wrote:
No. The drive is not reflected in any window. Not on my computer or disk utility. It initially was shown just before Time Machine started. It was then I escaped from time machine and I eventually returned the first drive after reformating it to fat 32 (on a windows machine) and it still wouldn't show up the MAC. The second drive now does the same as the first (doesn't show and cycles) but never showed up in any form on the MAC.
If the MAC has a register then my guess is some information about any external disk has been altered and I should need to to return it to it's original setting. That is because the second drive is doing the same as the first. I just don't know how to do that or even look.
If it uses the MBR (Master Boot Record) partition scheme, for Windoze, TM may have started to reformat it to GUID, but had that interrupted when you cancelled. If DU can't see it at all, there's not much you can do from your Mac. You may need to reformat it on a PC, then do it over on your Mac, via item #5 in the FAQ.
There are reports of problems with some WD drives having not working well on Macs. You might want to check their website support/forums, etc.

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=

My external 1tb My Passport won't display

The eternal displayed this morning, was ejected properly, now won't display other than in Disk Utility, however, it won't allow me to access or eject it.

Thanks Tom! Interestingly enough, everything was set properly. The 1tb icon showed up in my 5 year old MacBook Pro so ... took a 5mb external, plugged it in on new MacBook Pro - it displayed fine - left it plugged in, put the 1tb in and it displayed! Some days ... thanks for the information as I hadn't actually done that.

WD Passport Won't Mount

Hi-
I have a G4 MDD 1.25GHz running 10.4.11 with a USB 2.0 PCI Card (don't remember the brand).
Last night I bought a Western Digital 500GB Passport drive (USB powered only) for use with the G4 and my MacBook Pro. When I plug it into the G4, I hear the drive start up and click repeatedly, but it will not mount and does not show up in Disk Utility.
The most I can gather from searching online is that it is a USB power issue and that the best remedy is to purchase a USB 2.0 Y-Cable.
Just wondering if anyone else here has had this issue.
Thanks,
Todd

...with a USB 2.0 PCI Card (don't remember the brand).
The chipset on the card is more important that the brand marked on the card's box. Open System Profiler and click on the "PCI Cards" section. All your PCI cards should show in the main pane. Click on any listed as "usb" and look at the vendor code. Code containing "1033" have the preferred NEC chipset and usually do fine.
Normally a PCI USB card gets plenty of power to external devices unless you have all your slots filled. Then available bus power may be reduced to all the cards. If you have a card you can do without temporarily, pull it and see if the drive mounts. If so, you have too much competition for the available electrons on the PCI bus.

HT4623 Passport won't load with new update

I just downloaded ios6. When I click on passport and then app button it comes up with a error message can not connect to iTunes

Before doing anything drastic as an Archive & Install to move to a lower QT version, I suggest that you update your OS system first. According to your system info, you are using the basic Tiger version which is outdated.
You should update your OS all the way up to the last Tiger version, use Software Update to install all the available updates that goes along w/your computer & the OS.
Repair permissions & restart your computer.
