Disk Utility Error Message for Firewire HD: Could not unmount disk
I have one internal HD with 10.4.2, another with 9.2.2, and an external firewire with 9.2.2. Sometimes the firewire does not show up on my desktop, or when I try to copy files onto it the beachball spins endlessly. When I try to reboot holding down the Option key, the firewire HD does not show up.
I ran TechTools 4.05 (while booted from my Tiger HD) on the firewire HD. Everything checked out.
I tried running Disk Utility on the firewire. The first time this is what I got:
"First aid failed. Invalid key check. Volume check failed. Error: The underlying task reported failure on exit."
I ran Disk Utility again:
"Repairing disk failed with error. Could not unmount disk."
Any suggestions would be appreciated.
Your firewire disk is damaged. Try that: restart in safe mode (pressing SHIFT after the chime). Wait for complete boot. Plug the external HDD. Try again with Disk Utilities. Wait the report. My advise is to check its integrity. Try repair. If nothing works, try with DiskWarrior (the best utility).
If DiskWarrior can't do the job, you – definitely have a damaged hard disk.

I uninstalled and then re-installed with no success

ThanksThat message is indicative of a corrupted file.
Since you've already tied re-installing, the Photoshop preferences file comes to mind. Re-installing without first removing the Preferences file is futile, as you end up right back where you started.

Disk Utility: "Repairing disk failed with error Could not unmount disk"
Disk Utility: “Repairing disk failed with error Could not unmount disk”
Hi. I’ve been experiencing some mildly squirrelly behaviour with my system (vide infra) so decided to repair the two internal hard drives on my computer. The primary hard drive is a 74.53 GB ST380013AS that came with the system; its S.M.A.R.T. Status is “verified” and Disk Utility repairs permissions just fine. However, the second internal drive (Maxtor 6L250S0, 233.76 GB, lower Bay, Journaled HFS+), despite being verified by S.M.A.R.T. status and apparently running OK, fails to unmount when I ask Disk Utility to repair it- I get the above error message in red. I have repaired this disk with DiskWarrior (v3.03) and all appears to run AOK. Can anyone tell me why I cannot get Disk Utility to run on this secondary (eg, non-startup) disk? I have tried many times and the error is reproducible. Thank you!
G5 1.6GHz PPC, 1 GB RAM, running OS 10.4.6Thank you for these useful links!
For others who have this issue, I also found very helpful advice given to this question on the MacFixIt forums by MicroMat Tech3 at
http://www.macfixitforums.com/php/showthreaded.php?Cat=&Board=tiger&Number=76265 1
He said: "Use the lsof command to find the open files on a volume that does not unmount or eject. Open Terminal, located in /Applications/Utilities. Type: sudo lsof | grep Leave a space after the p in grep, then drag the icon of the problem volume to the Terminal window. The pathname for the volume is pasted in for you; press Return. Then enter your administrative password at the prompt, and press Return."
At this point, one now has a list of the open files/processes on the volume that will not unmount. You can use Activity Monitor to terminate these processes if you wish, and then the volume will unmount as it should. -
Trying to make a dvd from a project and this error message appears .The project could not be prepared for publishing because an error occurred. (-2125)
Hi
Error -2125
OK Error code - 2125 usually indicates that the movie is to large.
It use to pop up when going to iDVD !
iDVD - DO NOT CARE ABOUT Gbs at all. I got movies on 500Mb that do not fit and 50Gb that fits nicely.
iDVD - ONLY CARES ABOUT - Duration. Duration is Movie time + MENU TIME. Choice of
menu and animation of this can take lost of "DURATION" 15 minutes or even more.
Choice of encoding method and use of SL or DL DVDs determine the DVD limit.
iDVD 08 & 09 & 11 has three levels of qualities.
iDVD 6 has the two last ones
• Professional Quality (movies + menus up to 120 min.) - BEST
• Best Performances (movies + menus less than 60 min.) - High quality on final DVD
• High Quality (in iDVD08 or 09) / Best Quality (in iDVD6) (movies + menus up to 120 min.) - slightly lower quality than above
DL DVDs can store about double of these times.
ALTERNATIVE - The Error Code can indicate that free space on Start-up (BOOT) hard disk is
less than 25Gb (my minimum)

If you are getting OSStatus error -2125, I've seen this caused by the computer display sleep settings.
Try changing the sleep settings to never and see if you are able to export.

I just replaced my iPhone 5 because of a cracked face. I backed up the old phone to iTunes. When I tried to restore my data off of iTunes to the new phone, I got an error message saying that iTunes could not restore the iPhone because not enough free space is available on the new iPhone. Now what?
I have Apple Care+, but I'll be darned if I can find any way to contact anyone at Apple to talk to about this. They take your money, but make darned sure they don't have to support you unless you jump through a bunch of hoops first, like this site.I've done a restore.. The phone was completely wiped back to factory settings.. It then tells me there isn't enough space on the phone to restore from back up? How when the phone is empty?!

Hi: I am having a problem with an external HD (WD 750 GB Caviar Black) housed in an OWC enclosure and attached to my PowerPC G5 running OS X 10.4.11. The only use the drive has seen is trying to create a clone of my primary HD onto a partition on the external using a highly respected application dedicated to this purpose. For some reason yet uncovered, every cloning attempt has stalled the application and hung up my system. That aside, what is happening now is that I cannot even leave the ext. HD powered on and attached to my G5 as within minutes of booting up, my system slows down and becomes unresponsive. Detaching the ext. HD frees my system up instantly.
The last time I ran Disk Utility on the external, it passed verification and I was even able to run DiskWarrior on it and restore the directories to perfect order. But now, even after booting up from my original Mac install disk, although the external shows up in Disk Utility and I'm able to verify it just once (and it passes), any attempt after that to erase it, repartition it, verify it again, results in the error message: Could not unmount disk. Eventually I get the spinning beach ball and have to detach the drive. The drive does not make any unusual sounds and I have to put my ear to it to hear it at all. At one point, on boot up, the blue light on the enclosure continued to flicker for a very, very long time and the drive refused to mount altogether. But it hasn't done that again. I've read that when a drive won't unmount, it can mean that there are open files on it.
Anyone have any ideas as to whether it sounds like a problem with the enclosure or the drive and any suggestions as to what I might try? I have tried connecting it via eSATA, FireWire and USB (all from the same enclosure) and the results are the same.
JackHere's an update. Received the new enclosure. Before I transferred the drive into it, I unplugged the internal cables from the old enclosure that were connected to the drive and then reattached them. Also, I noticed that one of the cable plugs was not perfectly seated on the circuit board, so I pushed that in a bit. Heard a tiny click.
Using the old enclosure, the drive mounted quickly and I was able to Zero Data on it and erase it using Disk Utility. Was not able to Zero Data on it before. Would hang every time.
Thought I would try a different cloning app than the one I had been trying to use and this time the transfer did not stall. The estimated time, however, was about 6 1/2 hours which I thought was way too long to transfer 190GB via FireWire 800. The transfer rate started at 4.5MB/sec and went up to 9.5MB/sec. So I thought I would try the new enclosure and see if that was faster. I stopped the operation, erased the partition and transferred the drive to the new enclosure.
Tried the same cloning app that worked in the old enclosure and this time it stalled shortly after starting to copy files. Erased the drive and tried the original cloning app that had stalled using the old enclosure. It stalled using the new enclosure also. Erased the drive and tried the Restore function in Disk Utility and that went through. Took 4 hours. Attempted to boot up from the backup that Disk Utility created but I got the circle with the diagonal through it and it just hung there, with my fans running at top speed. Finally had to power down manually.
I'm thinking maybe it's the drive that's malfunctioning. It is still under warranty. Even though I'm not able to boot from the backup partition Disk Utility created, I'm wondering why it was able to transfer 190GB of data when the other two, well respected cloning applications stalled. -

I am looking to solve without buying DiskWarrior unless only resort.So it looks like solved it for now I will update later. What I did was after starting from the install cd for the 10.6 system I ran from terminal ran:
diskutil disablejournaling /dev/disk0s2
diskutil disableownership /dev/disk0s2
diskutil repairPermissions /dev/disk0s2
then i closed terminal and then when to disk utility and chose to repair disk with results all was fine. Then ran repair permissions and got similar results from terminal function next I erased disk and then chose to restore from time machine and it is now restoring! yea! -
Disk Utility, 'Could not unmount disk'
In what state - if any - does Disk Utility leave a Disk or Volume when I get the 'popup' error, "Could not unmount disk"?
I've had this on a variety of SATA and Firewire 400 disks under Tiger; typically, repeating the process in question (a Repair, Erase or Partition) seems usually to be successful, eg:
Creating Partition Map
Partition failed for disk Maxtor 7L250S0 Could not unmount disk
Partition complete.
(That's from DU's log; to me it's contradictory.)
But it looks as though something is set somewhere as a result of the apparent failure and as though there is a knock-on effect for such cloning s/w as the excellent SuperDuper!
I have ruled out hardware and experienced this 'error' with three different drives from two different manufacturers.
Is some bit or similar set somewhere which marks the drive as unmountable to the OS and third party apps, even though it is always subsequently usable in the Finder?
TIA!

I'm really dumbfounded on this one and it's driving me bonkers!!!! On some of my music files there is a ! in front of it, if I try to play the song, I get an error message; "The song "_____" could not be used, because the original file could not be found. Would you like to locate it?"
This began to happen when Chuck made playlists2burn on2CD-and then he would delete the playlist; sending all the song files into oblivion. Certain songs have a ! right next to the file name, and as I stated before, i get that error message:
"The song "_____" could not be used, because the original file could not be found. Would you like to locate it?"
So I click on "Locate". No help. I get a menu with folders that say "catroot" and other folders which names I cannot remember, but I scroll PAST the file folders, & it's just a bunch of ".DLL" files.....I don't understand what any of the names of the folders mean...it's frustr8ing-coz this is my 2nd iTouch, my 1st one got stolen & I can't afford2buy my music back at this time & i NEVER before had a single problem with losing song file locations.
Is there anyone out there who has been through this frustrating game of chasing your tail?....<that's how I feel>
If so I would be ever so gr8ful if maybe someone with the knowledge would be so kind as 2 tell me how/where 2 retrieve these songs & how to put everything back where it belongs, I would be 4ever gr8ful !!!
I can't afford 2 replace the songs just like I'm unable 2 buy back my old music from my stolen iTouch....man that was an awesome collection-someday I'll be able 2 afford 2 do that & I would like 2 have all the new music that I paid 4 but cannot find when I got my new iTouch....that would just be wonderful.
I hope someone sees this post that can help me retrieve these files....losing $100.00 of iTunes is a REAL BUMMER!!!!!!
ThanQ SO very much!
[email protected] or [email protected] or [email protected] .
You can also find me on Facebook, my given name is Tiffinie Trimmer, &
that's my Facebook "handle". ThanQ 4 taking the time 2 read all of this!
hope 2 get a reply someday....I'll B checking all my emails & my Facebook, as well
as marking this page in my FAVORITES so I can find it fast! Take Care!!!I was not complete clear.
Since you never changed the settings in the advanced section of iTunes preferecnes, you have to chech that your music is really in the location setted in the folders reported in the advanced section. If not you have 2 ways: reset the position of this folders or in the actual disk organisation or in the pointing on the preferences.
If you press the reset button you just give to itunes its default setting as for the position of the music files: probably this will be a good choice if you have never changed any default preference.
But before I would check the folders and see if the songs are really there
In my iTune I have this, and I believe it is the default.

One of my external hard drives died. I had several iPhoto libraries in it. Fortunately, I used Time Machine to backup to a Time Capsule and I can see all the iPhoto library icons in Backups.
When restoring the first iPhoto library, after three hours, I got an "unexpected error" message and the operation could not be completed. Indeed, the restored library is smaller than the library in Backups. Is my best choice to try again and replace the restored library (which apparently must be missing some photos)? It would mean another 3 hours plus of restoration with fingers crossed...
Any suggestions? Thank you in advance!I am always suspicious of using a different OS to the one that was used to run the backup.. ie if you used Snow L to backup then there is absolutely nothing wrong with using SL to restore.
Mount the TC sparsebundle and verify it using disk utility.

You might also like to load the widget in Time Machine so you get whatever the full error message is..
I cannot find any reference to the error code you are getting..
My recommendation would be to try it on a different computer.. restore the whole backup to an external drive large enough to accept the whole backup.
Use the manual methods pondini recommends.

My nano will no longer sync to itunes. I tried to restore it and error message 1437 said it could not be restored. Any thoughts on how I can sync or restore?
Good day billoelwein,
If you are having an issue with your iPod nano being unable to restore, you may want to first try resetting the iPod. See the directions in this article -
Reset your iPod - Apple Support
If the issue is still present after a reset, you may need to restore your iPod nano back to factory settings. See this article -
