PowerPC :: Hard Drive Not Working / Repair Volume Failed Could Not Unmount Disk
Jul 17, 2009
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?
I have recently purchased an iMac (21.5" - 3.06 GHz Intel Core 2 Duo - 4 GB 1067 MHz RAM - 1 TB harddrive) with OS X 10.6.2 installed. I have to say that after over 20 years with MicroSoft I am enjoying the stability and quality of the MAC. Anyway, as part of my education in the care and feeding of a MAC I ran the TechTool app yesterday. I had no indication that anything was wrong with the computer - but, I would like to become familiar with the various utilities for the care of the machine "before" a problem occurs. As the app ran I was pleased to see that all the tests passed (Processor, RAM, Video RAM, etc.). However the computer failed the last test: Volume Structure.
Here are the directions I was given at the end of the test: Volume Structure Failed TechTool Deluxe can scan volumes for problems related to the numerous structures that are necessary for the volumes to operate correctly. If problems are found, TechTool Deluxe can attempt to repair the damage to help reduce the chance of future problems. If TechTool Deluxe has discovered problems with the structure of a volume, allow the program to repair the problem. Quite often these issues are minor, but sometimes they can be indicative of a more serious problem. If the problem persists, consider backing up the device, reformatting the media, replacing the data, and then testing again.
I was also instructed to access the Apple site and download the most recent version of TechTool Deluxe that can perform repairs. I downloaded the software and followed the instructions to open the file in the Disk Utility app and burn a CD. Following the directions I then booted up on the CD by restarting the computer while holding the "C" key. The computer booted up on the CD and loaded TechTool Deluxe. I ran the same tests as above and once again the Volume Structure failed. When I clicked on repair it seemed as though the program was trying to fix the problem - then it abruptly stopped and stated that the Volume Structure could not be repaired.
I removed the TechTool CD, rebooted the computer, installed the TechTool Deluxe that I downloaded from Apple, and ran the Disk Utility. When I tried to "Verify" the disk this is what appeared: Disk Utility stopped verifying "Macintosh HD". This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk. Following these instructions I rebooted the computer using the Mac OS X installation disk - and the only option I found was for an installation of the OS.
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.
In trying to repair my hard drive, which disc utility said was corrupt, it stopped repairing it because it could not unmount the disc?I booted my macbook pro from my backup hard drive.
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 am considering purchasing diskwarrior but want to make sure it can help my situation before I purchase it. My imac will not boot from the internal hard drive (Intel processor) When I use disk utility to try and repair the disk, I get error messages and it won't repair. I can see the HD but cannot repair it. When I connect using target mode with my mac book pro, the hard drive does not appear on my host (macbook pro) computer. I have reloaded OS X (Leopard) onto a firewire external drive and can boot my imac that way but I can not find my original internal Macintosh HD. Will disk warrior be able to help with this scenario. I would really like to access that internal Macintosh HD and retrieve my files.
I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state! Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.
I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive” Checking file system Volume repair complete. Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
I have a Macbook PRO late 2011 running OS X Mavericks.
I ran installer then went to disk utility and pushed disk repair. it ran and indicated in green that no repairs were necessary. i then went to startup disk and only the Diks and network startup showed up but no hard drive. i also open computer to make sure was not wet muddy due to leak in cooling system but all was dry
I've just transferred my data to a new computer and now need to erase the hard drive on my old one.. I've tried Disk Utility, increased the security, and tried 'erase' but I keep getting an error message "couldn't unmount disk". I've gone into Partitions and tried deleting the HD there as well but I get the same message. I just want to get the computer securely wiped and would like to keep Lion as the operating system.
Over the last few weeks, I have been experiencing crashes on my Macbook Pro. The crash would appear as such: I'll be using Chrome and all of a sudden pages won't load. The mouse continues to work, but if I navigate to the desktop, folder won't open. Then, if I try to quit programs, the dock either becomes unresponsive or programs will only quit if "forced quit." Then the beachball of death appears. The beachball of death will continue for a very long time—perhasp indefinitely, so I decide to manually power down the computer.
I have tried to verify the hard drive in Disk Utility, and a few times I have gotten this error: Volume bitmap needs minor repair for orphaned blocksChecking volume information.Invalid volume free block count(It should be 46122698 instead of 42839276)The volume Macintosh HD was found corrupt and needs to be repaired.Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the Mac OS X Utilities window appears, choose Disk Utility. So I restart from the system (command-R) and repair the disk. But now within a day or two I get the same error. Does my hard drive need to be replaced? Am I on borrowed time? My computer is under warranty. Do you think Apple will replace the hard drive?

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 try to insert my hard drive and it says "the disk inserted is not readeable by this computer" but when I open disk utility to repair it says "First Aid failed, Error: filesystem verify or repair failed". I am very frustrated, my work is due next week and most of it is in the drive.
My PowerBook G4 (Alum) died. I've had it for 4 years, taken it with me to Alaska and all over the lower 48, and have had nothing but happy experiences. I knew she was gonna go, but I was hoping she'd hold on until I could afford a MacBook. Alas, no. The problem appears to be the ability of the logic board to communicate with the hard drive. I can hear the HD spin, but even with Disk Warrior, I cannot locate it. The Mac Geniuses at my local Apple store confirmed this and gave me a shoulder to cry on. I've run Disk Warrior, Disk Utility, and tried finding it using the target disk mode - no luck.
The problem is that I've got 4 years of teaching materials, 6000 songs, and irreplaceable pictures on the HD, so I can't bring myself to just trash it. It's true that you only fail to back up you stuff once. This is my once. I've heard that with PC hard drives, you can just drop the old HD into a USB HD box and use it as an external HD. I can't afford professional data retrevial, and I want to give this option a try if it'll work with a Mac HD. Any ideas or suggestions?
I have an Intel Mac Mini running OS X Snow Leopard, the problem is since last November, I've had to use Disk Utility and my Snow Leopard Installation disk to repair my volume because of Permission problems, at least 3-4 times. And I know I shouldn't have to do this!
I have an external WD drive in a self-enclosed case, both purchased from OWC, used for my Time Machine backups. The disk and backups have been running just fine since I began using this disk over a year ago.
When I plugged in my disk yesterday (USB), it didn't mount. I ran Disk Utility on my 'Time Machine' partition, starting with verify disk. It reported that it needed to be repaired. When I run repair, it runs for several minutes and I see information of what is being done -- incorrect block count for file shutdown_time, incorrect block count for file permStore, etc -- but I always ends with "Disk Utility can't repair this disk" and that it needs to be reformatted.
I've run Repair Disk multiple times, all with the same answer so it seems running it again won't change the problem. Reformatting and starting fresh with Time Machine seems to be the only course of action
What specific issues should I be aware of as I reformat my Time Machine drive/app partition?

Ive recently had to repair my startup disc volume/reinstall Tiger and now my iPod doesnt store songs after I sync it. All of my music is in iTunes and everything else seems to be working however once I disconnect my iPod NOTHING is there.
Ive been looking through all the previous discussions but cant seem to fix this on my own. And Im not even sure if I should be posting this question on here or in another forum...because Ive also noticed that there are no pictures in iPhoto .when I did the repair...it asked me if I wanted to save a copy of the previous system which I did.
I'm trying to erase my SSD internal drive that is corrupted software (Yosemite).I'm booting from an external with 20GB Yosemite OS & 480GB that contains files I've dragged off the internal SSD.I'm getting the error:Volume Erase failed with the error:Couldn’t unmount disk.How can I get around this?
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?
I have a Macbook Pro . The hard disk failed smart disk and my laptop does not start any more. Is it ok if I replace the HDD with CGET or WD hard disk rather than the apple hard disk. the pros and cons of a non apple HDD.
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 have a dual 1.25 ghz MDD Powermac G4. It was working fine until a couple of days ago. It froze up, I restarted it. I got a blank blue screen.
Also, the computer made some awful clicky noises that I've never heard before.
I booted from the OS X installation CD. Disk utility lists the WD1800 hard drive, but I can't do a re-install and there's no option to repair it.
I can't erase or partition it because when I try, I get a failure message saying it can't be done ("chosen size not valid for chosen filesystem"). The HD is listed in system profiler... with a capacity of 0 bytes.
I assumed that the hard drive had died, so I went to a local PC shop and bought the only IDE drive they had (a Maxtor 6l250r0). I installed it, then booted from the OS X CD.
I know that new hard drives need to be formatted, but I assumed that this could be done with disk utility.
But disk utility can't find the new hard drive, doesn't list in the left column. It shows the optical drives and the install CD and the old WD hard drive which can't be erased or repaired, but no new hard drive.
It's not listed in the system profiler, either.
I checked the cable connections and tried installing it in the front carrier rather than the rear, but nothing works - disk utility and system profiler can't recognize it.
The only other desktop mac I have access to right now is my old 450 mhz Sawtooth G4. I tried putting the HD into the sawtooth and got the same results - disk utility and system profiler can't find the new HD at all, but has no trouble finding the old 20gb HD and the DVD and zip drives.
I'm... not really sure what to do here. Am I doing something wrong?

I recently received an iMac as a "gift"... turns out it has some problems. I am unable to reinstall the default OS (Mountain Lion) because I have yet to be able to partition the HDD correctly. The error I keep getting is: Partition failed with the error: Wiping volume data to prevent future accidental probing failed.At this point, the default Macintosh HD isn't showing, so it must of been erased/deleted.
