Disk Utility says volume needs repair, tests failed. Now what?

What exactly does this mean? Unfortunately, I bought this TiBook from a classmate, and he didn't have his Tiger DVD, so all I have is 10.0 and a 10.1 upgrade. Do I have to use this to re-install?
Thanks!
Jim

Hello James:
Since you do not have the Tiger DVD you have a few choices (none particularly good). You should ALWAYS have the software install DVD - I am not sure what will happen when you run repair disk from an older software install CD/DVD. You will be unable to reinstall Tiger unless you have the proper DVD. I would return the iBook and get my money back from your classmate unless that person produces the proper software.
Incidentally, if Apple's repair disk (run from the CD/DVD) is unable to repair problems, DiskWarrior is the next option. DW is the 'gold standard' of directory repair, but it is pricey at about $90.

When I try to load off the Install CD to do the repair, I get an error saying something about "Kernal" and a grey box saying I need to restart.
I ran TechTool Deluxe and it did not find any problems.
What do I need to do to resolve this? I am not exactly sure what is wrong as I am not THAT technically inclined.
Any directions/help is greatly appreciated.
Thanks

Welcome to Discussions - what you are having are kernel panics, see Dr Smoke's Resolving Kernel Panics and follow his directions.

Disk Utility says HD needs repair-how to boot from original disk?

Hi,
My iMac has been acting up badly. Finally on Friday, it had trouble turning on and a burning smell arose from the top. Came on but with the blinking folder with question mark. So turned it off and tried again to turn on: no chime and couldn't turn it on.
Went to Genius bar this a.m. Tried different cord. It turned on. Everything came up fine. Genius ran special test. Everything came back with green check. But he said the internal hard drive could very likely be starting to fail.
Back home. Just ran the Disk Utility to "Verify." It couldn't continue verification. Got these messages:
Invalid volume directory count.
Error: Filesystem verify or repair failed.
The volume Macintosh HD needs to be repaired.
Questions:
1) Can I repair using the First Aid utility (or is it more about getting a new HD)?
2) If so, can someone remind me what keys to press on startup to boot from the CD?
3) I have 10.5.8 right now. Can I still boot from the original Tiger installation CD and use that Disk Utility?
Thanks for your urgently needed help!

If you're on 10.5.8 have you not got that disk as that would probably be the best one to use? If not, the disk that came with your Mac should still boot up. Disk in drive and restart holding down the 'C' key. Hopefully it'll boot - albeit slowly. At the multi-language screen choose your language and at the next screen from the menu bar select Utilities>Disk Utility. Select Macintosh HD on the left and 'repair disk'. Hopefully it'll do the necessary repairs. If it fixes anything click 'repair disk' again until you get a clean pass and then from the Apple menu restart as normal.
If you haven't got a backup make sure you make one ASAP.

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?

If you are running Tiger, you need the Tiger install disc you purchased in order to run Disk First Aid repair.
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.

Disk utility stopped verifying; need repair... over and over and over

I've gone through the restart, Command+R drill 4 times. Repaired the disk using "Disk Utility." Restarted after repair, ran disk utility to verify the repair and BAM disk utility stops verifying and instructs me to restart ... etc.
The errors have been consistent: orphaned blocks, invalid volume free block count. But when I use utility disk after restarting and pressing command+r, the "repair disk" does not appear to do anythign beyond "Load and Verify" freespace summary and block accounting. Am I missing a step?
Any suggestions appreciated.

That article does not pertain to the OS you are running. "This article has been archived and is no longer updated by Apple."
It pertains to using fsck not Disk Utility for:

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 HD, "needs to be repaired" Options?

Using Disk Utility to Repair Permissions has worked fine, but when I "Verify Disk" I get this:
"Error: The underlying task reported failure on exit" among other text. It says that our HD "needs to be repaired".
How do I do this best? What do you all recommend?
Is Disk Warrior the only/best option?
Is there another app that I should use first?
Is there a free option, using a built-in utility?

On an intel mac you cannot run OS 9 or classic so there is no need to worry about OS 9.
If you have the same problem and Disk Utility cannot repair the drive and you decide to do a reinstall you can either do a archive and install, which would not remove your old data and files but would just replace the system with a new one. Chances are that will not fix a problem with the disk directory.
If you want to reformat the drive and reinstall the everything will have to be reinstalled from scratch as it will all be erased.You system restore disk can be used for this and then any third party apps you have will have to be reinstalled.
Before doing either, I would recommend that you do a complete backup to an external drive using Carbon Copy Cloner or Super Duper or some other backup application.

Disk Utility - Partition map needs repair because a data partition needs loader space.

I just finished setting up both my OSX and Windows installs from scratch after fitting an SSD, which in-turn was right before my logic board died and Apple replaced it, now it looks like I have some sort of hard drive issue brewing.
This was my plan for the SSD, and how it currently displays in Disk Utility although that wasn't the case earlier:
And in Terminal:
My intention was to have two boot partitions for each OS, 'Macintosh HD' and 'Win 7 Pro' and a third shared data partition 'Projects' on the SSD, which I made in Drive Genius after installing Boot Camp. I don't want Macintosh HD accessible from Windows because I'll be using Paragon HFS+ or MacDrive to give write access and don't want OSs stomping on other OSs turf, hence needing three partitions. Everything looked fine until I just checked Disk Management under windows and realised it couldn't see the Projects volume. Even though it's fine in OS X, it was just marked black/unallocated space.
So I booted back into OSX, all my files look fine so I ran Disk Utility and the Partition tab looked really odd - unfortunately I didn't get a screenshot. All volumes reported their size correctly but visually, Macintosh HD took up most of the drive. I could see 'Windows 7 Pro' under this, but the Partition Layout section had a scrollbar, which if I scrolled down showed 'Projects' squished into a tiny gap at the bottom. I ran a Verify, which reported no problems, and at some time since the Partition Layout has reverted to how it should look (as in the screenshot above), with 'Projects' book-ended by "Macintosh HD' and 'Windows 7 Pro'.
Now when I run a Verify on Macintosh HD or Projects volumes, it says there's no problem, but if I run one on the drive, I get this message:
Volume Macintosh HD on disk0s2 has 0 bytes of trailing loader space and it needs 134217728 bytes
Problems were found with the partition map which might prevent booting
Error: Partition map needs repair because a data partition needs loader space.
I've only managed to find one other mention of this error here, but the fix is not relevant to me because I don't have Sophos installed. I've tried Single User/Safe Mode but it just boots into normal mode, so I can't do a fsck -fy.
** /dev/rdisk0s2 (NO WRITE)
Can't open /dev/rdisk0s2: Permission denied
That value in bytes is exactly 128mb, so I suspect the problem lies with one of the invisible partitions that show up in iPartition and Disk Management under Windows, but not in Disk Utility. I have backups and I suspect the root of the problem is partitioning in iPartition after installing Boot Camp, but I've never had issues with this approach in the past so I'm wary of just giving up and reinstalling Windows again will be massive hassle because I no longer have a SuperDrive and last time it refused to install from USB.
Anyone have any idea what's going on? It seems like the sort of issue Disk Utility should just handle, at least in Recovery mode, but it's not playing ball. It also doesn't seem like a massive problem since my files all look fine and performance is OK, so I'm reluctant to do anything major.
I'll update with a shot of the drive in Disk Management from Windows in a few minutes, in case that sheds light on anything. Thanks!

Similar issue here. I manually partitioned my hard disk for triple boot (using Gparted on Linux), then everything was just fine until I ran bootcamp, to do something as simple as create a boot USB.
I get the same error as a result and have to work my way into booting, by resorting first to a Linux live USB, then restarting from the live USB, to finally reach my rEFInd boot manager, or whichever boot manager should be initialized at startup.
I suppose that the cause in my case is that some operation "scratched" the protective MBR. See this:
http://www.mactech.com/articles/mactech/Vol.23/23.03/APMtoGPT/index.html
I am hoping to fix it using an external Yosemite installation media: see this guide -
http://www.macworld.com/article/2367748/how-to-make-a-bootable-os-x-10-10-yosemi te-install-drive.html
And as a last resort to reinstall.
I'll admit I am negatively surprised. I need this computer for professional reasons, and for the sake of "preserving the integrity of OSX", measures defined by Apple instead tend to make partitions far easier to damage. And this problem seems to affect a number of users.
As for what I have to go through to fix it: a 5GB download, during which I have to register my credit card to the Apple Store. "Pay first, get your free software next."
IF Disk Utility can fix it, from the external media, then fair enough. The hassle is unpleasant but it files as "a choice".
Otherwise you can file it safely under software design calamity.

IMac won't launch, disk utility says I cannot repair my Macintosh HD, back up files, reformat the disk and restore backed up files. How do I do all that? Help!

Disk Utility Says System RAID Degraded - Does this mean what I think it is?

Hi All
I have a Mirrored RAID Set for my System Drive - being two 931.5 GB Hitachi Drives. This Mirrored RAID Set I have called System RAID. If I click on the RAID Slice in the Disk Utility it says that the "System RAID" is Degraded, and under this [tabbed in] it says 931.2 GB - RAID Slice (disk0s2) Failed with the other under that saying 931.2 GB - RAID Slice (disk1s2) with no comment it has failed [obviously].
So if this essentially means my the first drive in my RAID set has failed then I will lose all data if the second fails also, is this correct?
So what should my next step be? Should I shut down the machine until I can purchase a spare drive to replace the currently damaged one? AND most importantly, HOW do I replace the drive and have it rebuild as the new second drive without erasing / losing data - IE what is the protocol now??
Please your immediate assistance is GREATLY APPRECIATED!
OH and AHH I've just seen in System Profiler that a 2 GB RAM chip appears to have failed

What is going on!!

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.

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

I have to replace my hard drive as it is failing, I'm away and just bought a new external HD for backups,,only problem is it is fsiling to backup without a reason. Disk utility says ex HD is ok. I need to backup before i get it repaired. Any Advice?

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.

bob:
Disk Utility reports "Underlying task reported failure" when repairing a volume is a serious directory error which Disk Utility cannot repair.
•I suggest you read through the article.
•Then, if you do not have an up-to-date backup, it will be a good idea to try to save as much as you can of your data.
•The article suggests using a third party utility. Disk Warrior and Tech Tool Pro are the best utilities for this job. You will need to get one of them and run it, by booting from the CD, or installing it on an external firewire drive or on a second Mac which you can then run in Firewire Target Disk Mode.
Please do post back with further questions or comments.
Good luck.

Disk Utility Question? Volume needs repair

Hi ALL, I need some help. My system seems to be running slow, so I did a repair permissions - that was OK then I did a Verify Disk and got the message."First Aid Falled" -"Volume Header needs minor repair

Volume needs repair " I have my Tiger Update disk but it will not bootup from it - not sure why? I do have my old install disk form my old iMac Version 10.1 - can I bootup from this disk and try fixing the issue? I would rather download something that's not expensive or free to help fix the issue. Any and all HELP would be GREAT!!!! THANKS Scott

Because the new software is insane. If there is a leading space on a line the line gets deleted. There's more insanity as well, but I would guess that's the problem with your post.
Anyway, your problem is that there is minor damage to your startup disk, which can probably be repaired. However, you can't repair the disk while booted from the disk. Boot from your install disk, then go to the menu and find Disk Utility there and use it to run the repair function, then reboot. If Disk Utility still can't repair the damage you need to buy a copy of Disk Warrior and use it.
