Disk Utility: Invalid Directory Item Count

I have noticed a minor problem with my Mac Pro when restarting. Sometimes it will fail to restart correctly and simply displays the grey screen (but not the apple icon). Usually powering down the Mac Pro will get it to start up correctly. Not ideal, but manageable.
I ran Disk Utility earlier to check what may be causing this issue and was given the following after Verifying Disk:
Verifying volume “Macintosh HD”
Checking file systemPerforming live verification.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Checking multi-linked files.
Checking catalog hierarchy.
Invalid directory item count
(It should be 33 instead of 32)
Checking extended attributes file.
Checking volume bitmap.
Checking volume information.
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.
If I restart and launch Recovery HD will I lose any data or mess things up? The machine works perfectly fine once booted and I was none the wiser to this error until I ran disk utility. The timing is unfortunate as I have just ordered a replacement drive for Time Machine due to an unrelated external hard drive error, so I don't have a recent backup which is a bit unnerving.
I want to run Recovery HD but I'm worried its going to cause a problem on an otherwise fully operational machine. I don't want to create an issue unless there is one (especially when I dont have a secure backup for a few more days). I also have Disk Warrior which has been fantastic in the past, but I cannot use it on the Mackintosh HD as it wont allow rebuilding of the startup disc.
So my question is: Should I run recovery HD now or just wait until I have a secure backup just in case it screws up? Is it possible Recovery HD may "create" a problem for me on my machine which runs and operates perfectly (minus the restart problem).

I went into Recovery HD and ran Disk Utility. It verified and repaired the permissions without any data loss or problems. As a bonus the boot problem seems to have been recitifed.

How to proceed from Disk repair "invalid directory item count" "this disk needs to be repaired"?

I'm trying to repair the hard drive on a MacBook running Mac OS X 10.6.8. To be honest I'm surprised the machine has lasted so long. It's very sluggish at the moment.
When verifying the hard drive, I get these details:
Verifying volume “Macintosh HD”
Performing live verification.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Checking multi-linked files.
Checking catalog hierarchy.
Invalid directory item count

The volume Macintosh HD was found corrupt and needs to be repaired.
"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."
How should I proceed from here? Is the only path to use a mac OS X installation disk (which I don't have, so would have to source and borrow)?
Many thanks

Get the disk and insert it in the optical drive, then restart holding down the C key. You will come to an install screen to pick language. Unless you want some other language click inter. Then before you go any further, look to the top of the screen for a drop down utilities menu. Go to disk utilities open an select your Internal hard drive use repair option in the menu and repair drive . You may have to do this more than once. If this will not repair you drive,you will need a third party repair tool such as disk warrior or a new drive.

Solution for invalid directory item count, startup disk corruption and regular crashes

Hi,
My late 2006 MacBook (10.6.8) has recently started crashing quite frequently. The screen becomes dark and a multi-language dialogue appears stating that the computer must be restarted with the power button. When this occurs any audio which was playing begins to repeat/skip and the computer goes into complete lockdown. This is now happening perhaps twice a day or more under moderate use.
This morning I ran 'Verify Disk' in Disk Utility and the process was stopped, stating that I had two 'Invalid directory item counts' and 'the volume Macintosh
HD was found to be corrupt'. Here is a screenshot of the Disk Utility window:
I have rebooted, run a software update and rerun the disk verification but to no avail. I also booted using CMD-S, advised by an older post in another forum which suggested using 'fsck -yf' which ran and stated that the disk had been repaired.
I bought the MacBook second hand from an Apple dealer but it didn't come with an install disc so I am unable to reboot and repair the disk like that.
My questions, therefore, are what does this mean for my computer in the future, will either of these issues cause me more trouble?
What can I do about it without the install disc
And are these issues directly related to the crashes? (I have been running the computer connected to an external drive and monitor - for watching movies)
Thanks in advance for any help you can offer!

Not much you can do without an install disc which can be purchased from Apple Store > Mac OS X 10.6 Snow Leopard - Apple Store (U.S.)
multi-language dialogue appears
That is referred to as a kernel panic. OS X: About kernel panics
Regardless of the kernel panics, you will still need the install disc to repair and reinstall OS X if necessary.
And are these issues directly related to the crashes? (I have been running the computer connected to an external drive and monitor - for watching movies)
Could be part of the problem.

Invalid directory item count

Hi all
I have a 2008 model iMac running Snow Leopard 10.6.4.
After installing the most recent security update this weekend, the machine rebooted and hung on start up (it was stuck on the circular activity indicator / gray screen for well over an hour). In the end I killed the power and restarted. The machine came up straight away.
I verified the disk using Disk Utility and it reported errors. So I rebooted into single user and ran fsck -fy, which fixed a whole bunch of stuff. Booted the machine and ran Disk Utility again, and it still reported errors!
Back into single user and fsck -fy the disk until it reports no changes twice in a row. Start the machine and run Disk Utility and again it reports a problem!
So now I am stuck in a loop:
- Boot in single user
- Run fsck -fy
- fsck reports that 'Invalid directory item count' error and corrects it
- Boot the machine
- Run Disk Utility, the 'Invalid directory item count' has returned
- Back to single user and it starts again
Can anyone advise on this? Do I need to worry about that message? It's the same error every time - and every time I fix it in single user and it's back by the time the machine boots. Do I just need to go out and buy DiskWarrior? I'd rather not - on the surface there's nothing wrong with the machine and I never would've known if I hadn't run Disk Utility after that hang.
Thanks in advance for any help

Thank you for the reply.
SMART validates as 'OK'.
I will try the hardware test. The OEM hard disk that came with this machine failed last year and the hardware test identified that before it finally died. However that had a lot of problems leading up to it - the machine would hang and was often very slow - checking Console showed a lot of I/O errors. Fortunately nothing like that is happening this time.
Hopefully this disk is OK. Thanks again.

Disk Utility: invalid volume file count & directory count

My MacBook OS X version 10.5.8 has ran quite slowly occasionally but I think that's due to the fact I've had it for almost 5 years. But then yesterday it kept on freezing every few seconds so that it was impossible to do anything. I then left it overnight and in the morning cleared the safari cache and kept rebooting it which eventually stopped it freezing so often. But now certain applications such as iTunes keep quitting before they even open properly and applications that do work still freeze every so often. So then I ran disk utility and verified the disk which came up with this:
"Performing live verification.
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
Invalid volume file count
(It should be 759557 instead of 759584)
Invalid volume directory count
(It should be 157930 instead of 157903)
The volume Macintosh HD needs to be repaired.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
Error: Filesystem verify or repair failed."
However the 'repair disk' button is dimmed so I can't click on it. Then when I typed in my problem on the help bar it said I need to use the installation disk to be able to repair this but I don't know where this disc is, so was wondering if there are any ways of fixing this without needing a disc?

was wondering if there are any ways of fixing this without needing a disc?
No.
You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair:
http://support.apple.com/kb/HT1782?viewlocale=en_US
Once that is complete reboot again from your usual start-up disk.
Call Apple Customer Support 1-800-767-2775, provide the Serial Number and specifications of the Mac, and for a reasonable fee, they will supply a replacement set of system discs (if available).
The discs will be for the original version of the OS that was pre-installed when the Mac was manufactured.

Disk Utility- Invalid Sibling Link

Can anyone tell me what this is about
Verifying volume “G5 HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid sibling link
The volume G5 HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
I had a similiar problem and posted this
http://discussions.apple.com/message.jspa?messageID=3486224#3486224
I have erased and installed the complete system (10.4) again and only been using Safari and ichat for a few days. I have updated all software etc.
I was about to migrate all my files back from an External HD FW and decided to Verify the disk quickly and this message came up.
Do i have to buy another hard drive?
If so what do you recommend? (about 250gb)
G5 2.3DP Mac OS X (10.4) G3 Pisimo 400, Maxtor 250gb External FW HD, ipod etc

If you have erased (but not zero'd the drive) and re-installed 10.4 after the first problem, and then it has happened again, you could try an erase with zeros (select 'Security Options' in Erase) and a complete new install of 10.4 and combo update to 10.4.8
http://www.apple.com/support/downloads/macosx1048comboupdateppc.html
'Zeroing' is supposed to map out the bad blocks on the drive so that they are not used.
When you have re-installed, you could run Disk Utility(the one on the 10.4.8 drive) and Verify Disk on the boot drive a couple of times. If there is any sniff of an error, see below.
But you may feel happier to replace the drive, as they are not that expensive. I have a Seagate 300GB as the second, 'data' drive, which was a good size/price combination at the time of purchase, but you may want a smaller, faster one as your boot drive. You will find many recommendations if you browse/search the forum.
Note that it is not impossible that other problems are causing the directory corruption - but getting the drive running right would be my priority. Good Luck.

Disk utility gets "invaild record count"

Hello, Using Macbook pro running OSX 10.9.2
Yesterday, i was using my computer searching internet, plugged it in and walked away for about 5 mins. Came back and tried to open iTunes. I 1st choose iTunes using the button w/ the 6 squares on it on the top row of keyboard. Nothing happen and iTunes did not open. 2nd I tried to open iTunes using the dashboard. Again nothing happen. I used the power button to shut down the computer. Then restarted, it came up with a window asking which language I would like to use. I choose English and then a new window opens with 4 choices; "Restore using Time machine", "Reinstall OSX", "Get online help" (which is how I am here now), and "use disk utility". I picked disk utlity and verified the disk which popped up a window say it "stopped and needed to be repaired. I hit the "repair buttom" and got a "Invaild record count" in red. It then stopped and said it could not be repaired.
Tried to restore using the back-up/restore with Time machine. It found time machine, but on about the 4th screen it asks which volume I would like torestore to. Nothing comes up and just says "searching for disks" None ever come up. I quit disk utility and then choose "Start up disk" under the apple menu. It doesn't find anything. I tried the "command + option + P + R" nothing is different.
So here I am. each new screen that comes up flickers a lot before clearing.
Dead hard drive?
Just can't find it?
What's next?
Thank you for being here to help

Start-Up: Folder with gray question mark / Disk Utility: Invalid Sibling Link

Yesterday, I was working on my computer and it froze up. My only option was to reboot by holding down the power key. When the computer restarted, the screen was all grey with a folder in the middle of the screen with a question mark.
I tried the following:
1) Boot up computer while holding down the "Option" key. - Didn't work.
2) Boot up the computer while holding down the "Shift" key. - Didn't work.
Since the first two options didn't work I inserted the original system install disk and booted up while holding down the "C" key. I selected "English" as the language and then opened "Disk Utilities." I pressed "Repair disk" within First Aid. The message I am getting is as follows:
"First Aid failed. Disk Utility stopped repairing "Macintosh HD" because the following error was encountered: Filesystem verify or repair failed."
The details screen shows the following:
"Verify and repair volume "Macintosh HD"
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid sibling link.
Rebuilding Catalog B-tree.
The volume could not be repaired.
Error: Filesystem verify or repair failed."
I ran the "Repair disk" function about 6 times but it was not successful.
I was then going to try to do an "Archive and Install" from the original system disk but when I go to do that no destination options appear at the "Select Destination: Where do you want to install Mac OS X?"
I have not backed up my data very recently (and a lot of what I have stored on this computer is work - I am a freelance designer) so I would like to do something that at least allows me to transfer my data off of my hard drive before reformatting or anything like that. Of course, if there is a less intrusive fix that can leave my hard drive in tact, that would be ideal.
Any advice? Tips? Solutions? I have a MacBook Pro, 15" that I purchased 3 years ago (my 3 year Apple Care plan just expired about a month ago).

You are in a tough situation. The disk appears unusable according to Disk Utility. As was suggested you may (only may) be able to salvage it with Disk Warrior (not sure about Data Rescue). DW can sometimes recover a drive that DU can't. But nothing else can be suggested.
If you can get that disk recovered then back it up ASAP, wipe the disk, reinitialize it, and verify it. But I'm the paranoid type, and with the kind of errors you show for that disk, I am not sure I would ever trust it again. At most I would relegate it to a scratch disk.
Note, if it is a drive that you bought, most drives have a 3 to 5 year warrantee period, so you could get it replaced by the manufacturer if it is within that warrantee period.

Disk utility invalid free block found

I ran Disk Utility because my computer seemed slow. DU said that I needed to restart and repair, but when I did that, DU said that the disc was fine. After re-starting, DU again said that it needed repair. The exact message was: "Invalid free block found (it should be 48071714 instead of 47831211) File system check exit code is 8"
Still running pretty slow. Don't know what the deal is.
Thanks!

A disk that has been "repaired" by Disk Utility has already failed and will fail again, probably in a very short period of time.
Back up your Mac if you have not done so already. To learn how to use Time Machine read Mac Basics: Time Machine backs up your Mac - Apple Support.
Replace the hard disk drive, or take this as an opportunity to upgrade to a SSD.

Disk Utility reports a block count error for a deleted file?

I carry out a regular scan of the hard drive and on occasions disk utility reports that a file has a bad block count. It is usually a large file like a CR2 or TIFF and is also one which has been deleted? Not only put in the trash but emptied the trash as well.
The only other thing of note, which I havn't checked if it is relevent to my problem, is on occasion when I go to empty the trash it reports it can't be fully emptied as one of the files is still in use, even though it isn't? If I use secure empty trash it dletes the file.
In case its relevent:
I use Canon's DPP & ACR for CR2 files and PS CS6/CC for TIFF's. I also delete TIFFS from within Bridge CS6/CC.
Both Disk Utility and Drive Genius report the SMART status as being OK.

Your backups may be hopelessly corrupted, but there's a chance an (expensive) 3rd-party Disk Repair utility might be able to fix them. For the moment, eject and disconnect the TM drive and try to repair the internal.

It appears that the HDD needs replacing.
I'm concerned the motherboard may also be faulty? How can I check (without purchasing another disk drive first)?
It seems strange (to me) that all information relating to the disk can be accessed, & all of the folders can be viewed using disk utility.
Yet the disk cannot be reformatted, or recovered from Time Machine back-up
Nor can the operating system be re-installed
Since I have Time Machine I presume I'll be able to restore the full profile to a new disk drive?
If I need to purchase a new disk (& the motherboard is ok), any recommendations which disk to buy?
Any suggestions why this disk failed? Is it related to 'sleep' and applications not shutting down properly.
Any advice most welcome.
with thanks

Inconsistent Disk Utility Results

When I run Verify Disk in Disk Utility from my boot drive, it tells me the drive needs repair. See log below.
Then when reboot from the recovery partition and run Verify Disk from the recovery partition, it says the disk is okay. Same if I run repair disk. What gives?

Okay, I have got a bit farther into this. I used CarbonCopyCloner to clone my drive to an external Thunderbolt drive and booted from the external. When I ran verify disk from the external it reported the same errors on the internal as it did when verifying while booted from the internal. Moreover, Disk Utility was able to repair the errors.
So it seems there is a bug of some sort in running Disk Utility from the recovery partition. It neither correctly verifies the disk nor does it repair it.
The errors are not, apparently, false positives as suggested above. DU, when booted from the recovery disk, reports a drive as healthy when it is not.

Disk Utility Not so Utile

So I verify my Hard Drive and it says the following after checking (exactly): Verifying volume “Macintosh HD” Invalid directory item count (It should be 43 instead of 42)
Checking Extended Attributes file. Checking volume bitmap. Checking volume information. Volume %@ needs to be repaired.",1) Macintosh HD Error: The underlying task reported failure on exit 1 HFS volume checked. Volume needs repair
The only glitch is the "Repair Disk" button is inoperative. So I trty to start from the original 10.3 OS that came with the iMac (3 discs) to use ITS Disk Utility and it won't start up from those disks. I either get a blinking folder when holding down "c", or I get a warning that says something like "this computer will not start up from this disk" likely because I have been upgrading Software (at Apple's request) since I started. I guess they forgot to upgrade Disk Utility. In any event, though this doesn't seem to affect the operation too much if at all, I still wonder why it won;t work properly (Disk Repair I mean)

Hi Lostdutchman, and a warm welcome to the forums!

You're very lucky it didn't, you cannot use 10.3's Disk Utility from a 10.3 Install Disc to repair a 10.4 HD, it'll mess it up.
They did change DU in 10.3.9 to work on 10.4 Disks, but no 10.3 CDs came with 10.3.9.
Some things to try...
Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, Validate again, if it's OK this time, click on Repair Permissions, reboot.
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).

Tough without the Tiger Disk problems, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
(SPACE between fsck AND -fy important)
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: 
The volume (nameofvolume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: *** FILE SYSTEM WAS MODIFIED ***   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

Then Safe Boot, (holding Shift key down at bootup), & use Disk Utility from there to Repair Permissions, reboot once more.
Your best bet is DiskWarrior, you need the CD/DVD though.
