HD problem - disk utility says "1 HFS volume checked" "Vol needs repair"
This all started with very slow response when applications were opened on iMac purchased 10/07 - went to Disk Utilty and tried to Repair Disk - but not allowed to click on that option(still grey). So, went to Disc 1 of Installer set of disks , inserted in drive and attempted to reinstall Mac OS X that came with Oct '07 (Tiger-right before Leopard became standard) purchase. When I get to the Select A Destination part of the Install MacOS X directions, there are no choices(ie- HD not recognized). Went to disk utility option available with the Installer disk and did a Repair Disk option. Following messages in RED
Invalid Volume Header
Invalid Mode Sgtructure
The volume Mac HD needs to be repaired ( ie- Volume check failed)
then Disk Utility boxpops up andsays Error: The underlying task reported failure on exit
Finally
1 HFS volume checked VOLUME NEEDS REPAIR in red
Huuuum.
Next step? I am using my wife's PC to send this HELP message and it's painful. Rescue me as the song says! Is it time to box up for Apple store visit, or ......
Houston, welcome to Apple Discussions.
It appears you have some directory damage on your hard drive. Disk Utility cannot fix some of these type problems. DiskWarrior can probably fix your problem. DiskWarrior by Alsoft

Is this a big problem?Is this a big problem?
Well, yes and no. It might be a problem, so you should definitively backup your data.
Then, boot from Installation disk that came with your computer and once you get to the installer, choose from Menu bar: Utilities>Disk Utility and try to repair your disk. If this doesn't help, you should try to erase your drive and reinstall the system.
If you have AppleCare, you might also consider downloading TechTools Pro from Apple for free. It is said to be more powerful than Disk Utility.
If the problem reappears, call Apple. -
Hi my hard drive is failing and I'm overseas in Thailand. I bought a Buffalo 1TB to back up my mac 13inch HD version 10.6.8, only problem is it wont back up. Disk Utility says ex HD is fine. I need to backup before I take it for repairs. What can I do? Thanks advice appreciated. NL
I think we both had our wires crossed a little.
Then just go ahead and clone your internal drive to your Buffalo. You are not going to use Time Machine, and you do not have to partition it. So ignore all that stuff I posted. Let me start from scratch.
First check that your Buffalo drive is partitioned GUID and formatted Mac OS Extended, Journaled. So open Disk Utility, select the topmost entry for the Buffalo drive. You should see something like this:
I have selected the entry of my CalDigit drive. Note that the Partition Map Scheme is GUID. Now, select the volume (mine is "System Backup."
Here you see it is a Format type of Mac OS Extended, Journaled. If that's what you see then you are good to go.
With Disk Utility still open:
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag it to
the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the Buffalo drive. Source means the internal startup drive. -
How do I fix a volume if Disk utility says cannot be repaired?
Greetings all,
Am having some annoying issues with my PowerMac G5 hard drive, nothing very specific, just lots of small issues like crashes and hangs and the fan going into hyper-drive every now and then. Started up from my system disc/Disk Utility and ran repair permissions and repair disc.
On repair disk it gets to the end then says:
1 HFS volume repaired
1 volume could not be repaired
I cannot find out what this means so can anyone advise?
I also run repair permissions over and over and it never stops finding something to repair.
Any advice much appreciated.Started up from my system disc/Disk Utility and ran repair permissions and repair disc.
Do you mean the System install DVD? - that's what you should do as you cannot repair an HD you're booted from.
On repair disk it gets to the end then says:
1 HFS volume repaired
1 volume could not be repaired
This is a little odd: is there another hard disk connected? Or possibly it was trying to repair the install disk as well?
I also run repair permissions over and over and it never stops finding something to repair.
Repairing permissions does thrown up a lot of things which can't be repaired: this is a bug arising from a system update and is harmless: you can ignore it.
You could try downloading Applejack which you run in single-user mode and provides an easy way of using the built-in disk repair procedure: this is quicker than starting from the DVD and you won't get any confusion with the DVD. It's quite safe: it doesn't do the check itself, just invokes the repair that you would get by typing arcane Linux codes. But note that you must run it only in single user mode (starting up and holding command-s while booting), never while booted normally. -
Disk Utility says everything's fine, but Install disk doesn't find my internal drive as a possible destination. When I startup with Command + S, I get a looping "cannot mount errno = 19" message.
Problem started when I used Tech Tool Pro 6 to "de-fragment volume". Had to cancel that process before it finished because I ran out of time. Thereafter, when I startup my machine normally, I get the gray Apple logo at first, but it changes to a prohibited symbol (circle with a slash thru it) and hangs.
When I startup holding the Option key, I can see my internal drive, but I get the same results as above.
When I startup using the MacBook OSX Install DVD, it does not find my internal drive as possible destination.
When I startup using the MacBook OSX Install DVD and then run Disk Utility, it finds my drive, allows me to "repair" and says everything is fine.
When I startup with Command + S, I get a looping error message "errno = 19" and cannot stop it to do anything else.
When I startup from Disk Warrior v4.4, it does not find my internal drive to do any repairs.
When I startup from Tech Tool Pro 6 and run the "computer check" diagnostics, everything passes but the Volume Structure, which fails at "Volume Extents (B-tree)." When I use TTP's "Tools" option to run "volume repair" it will show my internal drive and allow me to click the GO button, but nothing happens and nothing changes.
I have a Time Machine backup on an external USB drive, but for as long as the internal drive doesn't mount, I can't use the backup to restore.It's a false report and should be ignored.
I would not rely on TT as I've already said earlier even before Grant posted similar advice.
I really think the Rigid Disk Block may be corrupted. This holds the partition map and could prevent a volume from being unmounted. Unfortunately, there is no way to fix that without repartitioning the drive which will remove everything. So, before going down this road I hope you have backups or can make a backup.
Drive Partition and Format
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, 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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Proceed with reinstalling OS X.
5. Download and install Mac OS X 10.6.8 Update Combo v1.1. -
Disk Utility says I need to repair disk
My computer is running a little sluggish so I went into the Disk Utility and selected verify disk. I got the message below. I inserted the OS X disk but the repair disk option wasn't available. I bought the computer with Panther and got Tiger later, unfortunately I don't have the Tiger disk. How do I fix this problem?

And withhout your Tiger install disc, you cannot perform an Archive & Install retaining Tiger, etc. so bad move not keeping this in a safe place.
Your only other option is running fsck.

Hi, how do I manage storage? Disk Utility says “other” is taking up most of my storage but I don’t know where to find “other". Please help!
For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside a photo or iTunes library will corrupt the library. Changes to such a library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper 2>&-
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective 2>&-
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal. -
Several months ago I bought a 64GB PNY USB memory stick to transpord data quickly.
It seemed to work fine. I could format it as a Mac partition and use it. I hardly ever need
it so I just put it away.
Today I wanted to use it to put a file on and take it to the Kinko's/FedEx to print, and I
find I cannot mount it on any of my computers, iMac, MacMini or MacBookPro.
In Disk Utility virtually everything is greyed out.
Disk Utility says: "This partition can't be modified" "This disk is not writeable and cannot be partitioned"
If I try to mount it, it says "This disk cannot be mounted"
There is no physical read-only switch or setting on the disk that I can see and it is very small.
I has a Mac OS installed on it, so I wonder if that is a problem? I should be able to write over that
or reformat it I would think.Thanks for these replies.
I've got regular time machine backups and just backed up some of my data by copying some key folders to an external drive. I'm bit paranoid about backup integrity and would ideally like to do another full backup to a different drive using a system other than time machine, in the event that something goes wrong with the time machine backup. Any recommendations on good and affordable backup software to do a backup of my TM backup?
One other question: I seem to encounter problems like this pretty frequently. I'd say once a year or so, my drive fails completely or gets near enough to failing that I have to wipe and restore. (I've never had a TM backup fail to work, though the last go around there were some hiccups which has led to my backup paranoia.) I've had this happen on multiple computers, so I'm becoming pretty convinced that the problem lies somewhere in my data. Is it possible (even likely) that there's something in my data causing this recurring problem? If so, is there anything I might be able to do to try and pinpoint and address this problem? I'd love to go one year without having to wipe/restore my machine!
For a while I thought I just had bad luck. But I think this is like the 4th or 5th time this has happened in the past 4 years and every time, I'm restoring from a backup, so I come back with the same data. It's the one constant since I've had 3 different machines over this same time period. -
Disk Utility says "Error: The underlying task reported failure on exit"
So I decide to play around with Bootcamp for the first time, and I go through the install but it kicks me out, telling me there was some kind of HDD error. It points me to Disk Utility, and I click on Verify Disk, and then I get the following error:

So I do some searching, and Apple tells me that I need to reformat! ***?! There is nothing wrong with my HDD, or at least so I thought. No clicks, no shutdowns, nothing. Does this mean that soon my HDD might die? And if not, how the **** do I go about installing Bootcamp now?
Here's Apple's support document:
http://docs.info.apple.com/article.html?artnum=302411
Thanks much.
MacBook Mac OS X (10.4.8)You don't need to reformat.
Put your first installation disk in and reboot, holding down the C key when you hear the chimes. When the installation program starts, start Disk Utility from the menu and select your system drive, then do a verify/repair from there.
The reason it can't repair it is because Disk Utility won't do a low level repair on the system drive in case important system files are moved. When you boot off the CD, your system drive isn't in use and can be repaired easily. -
Yosemite on MacBook Air - Third time installed, now will not be startup disk. Disk Utility says OK. Disk Warrior says 375 pages of bad .plist files. How delete plist files?
What does "Accessibility" mean?Had the same problem, finally realized that the FileVault Encryption was struck at 19%. Speed back up to normal after I disabled FileVault using terminal command - sudo fdesetup diable
To check whether the FileVault is the culprit, go to System Preferences --> Security & Privacy --> FileVault to see if encryption is in progress.. For me the blue bar was less than a quarter with status 'estimating time remaining'..
Then open Terminal and type in: sudo fdesetup disable
It will then ask for the admin password (to be it asked twice), then it was disabled... Back to normal life again..
Here is my terminal log for reference:

Xserve RAID: Server Monitor says degraded, disk utility says mirror FAILED.
Xserve Quad Intel 4x2GH
4096 GB RAM
OS X Server 10.4.11
Xserve RAID 7TB 14x 500 GB ADM via dual fiber channel, Mirrored, 3.5 TB array.
Flashing yellow indicator light on Xserve this morning. Investigated and found that RAID Admin says everything is OK, all 14 drives normal.
RAID Admin log says :"4000 1 Wed Apr 08 09:37:59 EDT 2009 Disk 2 Failed To Respond. Retrying. RETRY COUNT:0 LBA:0x1C700"
Under the RAID tab, Disk utility says: "Mirrored RAID Set: Degraded" and "Disc2s3: FAILED"
All LED's are solid green across the front of the ADMs.
Since all my drives are reporting OK, could this be a problem with the Fiber Channel interfaces?
Should I just backup (again), shut down and rebuild the mirror using Disk Utility?Hi Kappy<
I am trying to migrate user data from a RAID - 1 slice from my old PowerMac G4 running OS X 10.4.11 to my new MacBook Pro running OS X 10.5.4 by reading a mirror RAID slice from my old Mac that is mounted in an external drive enclosure and connected by FireWire.
The problem is that the new Mac cannot read the old Mac disk, it never shows up on the desktop, or comes up as available when trying to use Migration Assistant. Then, if I go into Disk Utility, the external RAID slice shows up briefly with a locked yellow padlock beside it, then I suddenly get the window shade of death, and have to hold down the power button to reset/restart my MacBook.
Why can my new computer not read my old computers disk, and how can I change permissions, or make the old drive readable by the new mac.
Regrettably I am away from the original Desktop, and cannot load the old drive back into it, connect the two machines and migrate that way. My only option for reaching my necessary data is to retrieve it off the drive I have with me.
Thanks in advance for any help you can offer. -
My hard drive crashed. The disk utility says it can not repair. I tried to boot in safe mode but I stopped after 10 minutes. Is that impatient or how long can it take?
I have the installation disk but doesn't that erase everything?I have never bought a new computer from Apple so I don't know the details of what is covered by the warranty. You can try taking it to the Apple Store and they may have a copy of DW they can run. Or maybe not and they will just wipe the drive and reinstall the OS for you and if you haven't made a backup before they do that then tough luck. I'd check first!
If you buy Diskwarrior on DVD it will boot the computer. I think Apple Stores carry it, but you can also buy it directly from the vendor. I also don't use Lion OS so I don't know the details. You may be able to get their download version and boot from your recovery partition, then run it without a DVD. -
USB Hard Drive that Disk Utility says it can't unmount
I have a 93.2 Gb Hard Drive (from an old G4 PowerBook) inside an enclosure with USB connection. While trying to recover data from it using Data Rescue (on a G4 PowerBook), Data Rescue II hung. After restart, the USB Hard Drive can not be read at all. Disk Utility says it can't repair it or erase it because it can't "Unmount" the disk. What can I do with the USB Hard Drive?
try this: open system preferences/spotlight/privacy and drag that external into spotlight privacy then try Disk Utility.

Disk Utility RAID of 2 volumes, one drive mistakenly erased. Recoverable?
Thanks for any help.
I have a Mac Pro.
It has 2x 750GB drive formatted in Disk Utility as a RAID volume (striped).
I erased one of the volumes by mistake.
I know I can recover the data from the erased drive, but it will be useless without the other drive. So how would I go about restoring the data in such a way that it is recognized as the other half of the RAID volume again?
Thanks for any help.The commercial "SoftRAID" ($149) http://www.softraid.com
... is able to convert Apple RAID to its own format, AND has had excellent success for others in recovering in some situations.
They have excellent support so email them; a demo; and good PDF guides for download are worth a read.
