OS X Yosemite :: Disk Utility - Invalid Volume Free Block Count
Dec 3, 2014
I've run the disk utility verify disk several times and come up with an error (post title) indicating I have a corrupt HD and need to repair. I've rebooted with command R and run disk utility to repair the disk and it says everything is fine. Reboot to normal mode and verify continues to show the error.
Other info says the file system exit code is 8.
Info:
MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.2)

I seem to be getting an error message when i run Disk Utility, it says "Invalid Block Count, your disk is corrupt and needs to be repaired". I then repair it using the Lion recovery disk and it repairs it. Maybe a month or so down the line it appears again I then do the same and the end result is the same, can anyone help with this as it is worrying me. Also is there any way you can get rid of the bad sectors in the HDD when problems appear?

My wife's macbook pro started shutting down by itself randomly, so i performed Disk Utility Verify Disk and found these errors: Invalid volume file count(It should be 800651 instead of 800653)Invalid volume directory count(It should be 191005 instead of 191003)The volume Macintosh HD needs to be repaired. Error: Filesystem verify or repair failed. As i do not have the Mac OS Leopard disks physically with me, I target-disk started her mac on my mac, and use my mac to run Disk Utility on her hard-disk, and repaired the disk without problems.
However, this is the 3rd or 4th time this has happened. After the 1st time, i figured something is causing it, so i checked this forum, and found that for some, the Blackberry Messenger app causes programs, so i promptly uninstalled it fully (including associated system files) and this problem didnt come back for a while. Or could this be a sign the hard disk is physically failing soon? It is out of warranty now. We have regular Time-machine backups. We are actually kinda waiting out until the new line of macbook pro's come out..

I've a Macbook air without an optical drive just the USB stick with mac OS X which was delivered with it. Can I repair it or do I need to do a reinstall of all the OS X?

I have my imac apart right now and replaced the internal HD as it was not working. I assume the problem is the new one is not formatted with OSX, so from the INSTALL CD I opened the disk utility and see only one drive called "MEDIA".? Or is that just part of the install dvd that looks like a HD? In the system it shows as not formatted, 0 bytes. When selected in Partition it says :
"This voume is the startup volume and cannot be erased. Size 7.1 GB The disk is not writable and cannot be partitioned"
So i guess thats not my new HD I am seeing? Other than that there is only the two OSX install CD icons.

I purchased a new MacBook Pro 17" with OS X Lion (10.7.2) preinstalled back in January of this year (2012). I migrated my user accounts from my old MacBook Pro 15" (2008) running OS X Snow Leopard. Almost right away I started having issues of all sorts, including Admin accounts that wouldn't allow me admin priveledges, hidden user groups, apps that wouldn't run, multiple obscure error messages and a host of other issues. After scouring forums like this one I used Disk Utility and not only discovered innumerable permission errors but also disk errors like these:
Invalid volume file count
(It should be 1656658 instead of 1656636)
Invalid volume directory count
(It should be 345764 instead of 345743)
Invalid volume free block count
[code]....
And now, this morning, after a month or two of all that... and after installing the Java Security Upgrade last night, I can't get into my accounts at all. On first boot-up it hung for 20 minutes before I shut it down. After running Disk Utility from Recovery Drive and repairing the drive I rebooted and got the log-in screen. I clicked on my user icon, typed the correct password, was shown they white/grey screen for a few flickering seconds then was brought back to the log-in screen. I rebooted to the Recovery Disk, ran Disk Utility, saw all the same errors again, repaired the disk, rebooted and got the same problems with logging in again.
I've repeated this cycle five times today, as both a normal boot-up and in "Safe Mode" all with the same results. I've repaired the disk using Disk Utility from Recovery Disk as well as accessing the disk in Target Mode, and always there are the same errors needing to be repaired.
I don't buy that I'm dealing with a hardware issue. My antivirus and security software are all up-to-date. What the heck is going on? Why do I keep having these disk problems? Why can't I access my accounts anymore? Why does it keep hanging during boot-up? Why am I about to throw the machine out my bedroom window?

I have 43GB available on a 120GB drive on my MacBook base model and I'm trying to partition via BootCamp.I'm trying to allocate 32GB to the Windows partition but I keep getting the following error message:Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.Now I've backed up my disk and launched disk utility, and try to follow above directions here but the Mac OS Extended (Journaled) area is grayed out and when I click apply after highlighting the MacBook are (in blue), it errors out and says the disk is out of space.

Any ideas on this...my Imac (2.16 Ghz. running system 10.6.8) has bee having difficulty in starting up (lost of hard drive noise and crawling to start up) lately and I have Drive Genius 3 as a diagnostic tool, so I ran "Repair" and "Verify Permissions" and came up with the message" Permissions Error : ARDAgent. app....I gathered some info on these boards to use the app Pacifist (V 3.0.2), to re-install the ARDAgent and it should clear up the problem...followed the plan, ran Verify Permissions in Drive Genius 3, which said it was repaired...I then ran Verify to confirm and came back with Verify Failed, Invalid Directory Count, should be 38 instead of 39, and should be 47 instead of 45...But am getting the same results when I run Drive Genius 3 which is the Volume is repaired, but the Verify has failed.... A real stumper...any ideas? Also just up graded to Firefox 12.0 which is when the slowdown started to appear

Updating my hard drive to SSD. The first line is right on it's place: it tells the name for my SSD (which is: 1Tb Samsung EVO) On the picture below is shown the second line that is missing when the ssd is installed.Does this mean that MAC can't recognise the drive?Does it work properly?

I have to do a back up (I'm cutting in Avid) on this FAT32 volume (for interoperability it is formatted this way), but I can't mount it via the Disk Utility or the 'mount' command in Terminal (it doesn't list the device, despite seeing it in Disk Utility - the volume is greyed out).The drive is connected via Firewire 400 and 800, USB is not available (to few slots).

On one of our MacBook Pros (Late-2011), running the latest OS X 10.7.3, Disk Utility says the volume needs to be repaired. When I use Disk Utility from the Recovery HD, it says the volume appears to be OK. I verified by using fsck in single-user mode, and it found no problems either. Which do I believe? Is this a sign of a soon-to-fail hard drive?

Disk Utility when I run verify says I need to reboot from the Repair Disk. I tried (twice) and it shows no problems. When I reboot normally, and run DU, I get the same error. Which result should I believe?? And is there a workaround? Using 10.10.1 / Air late 2011.

I reinstalled Snow Leopard on a new volume, transferred stuff I wanted from the old volume to the new volume, and deleted the old one. In disk utility, I have not been able to stretch the volume to fit where the old one was. I can't change the volume scheme. Has anyone got a method to let me use my full 160GB hard drive rather than half of it? Or maybe software that can alter it.

I use Disk Utility (stand alone, on a USB key) to make backups of my system disk to an external disk and then transfer it from my home system to a MacBook and vice-versa when I need to travel.
Recently, I upgraded from 10.9.2 to 10.9.3 and, not long later, to 10.9.4. In the same period, I also had an increase (not a very big one, just a few GB, less than 15) in the occupied space of that system disk. The current amount of data on it is 164.64 GB.
I'm not sure if my problem comes from the sub-version upgrade, from the increase in data size, from both, or from something else. The home computer is an iMac with a 318.88 GB internal disk. The MacBook has a 500 GB internal disk. The partitions used on the external disk to make bootable backups are 400 GB big.
I can backup both internal disks to the external partitions (and boot on the resulting external disk when I check that it is usable). I can also copy the external backups to the MacBook system disk and boot on the result without problem.
But, recently, Disk Utility has started to refuse copying the content of the external backup partitions to the internal disk of the home system. It says there is insufficient space on the target volume. If the error message is correct, it means that I cannot backup 164.64 GB of data on a 318.88 GB volume!
For the record, the external backup partitions are OK when verified with SOS.

I have a 3 TB disk that I used for video files that I now want to use for backup. So I wanted to erase and partition the drive to wipe it clean. So after going into Disk Utility and "trying" to erase and partition the drive, it now only shows the drive and no volumes.I cannot create or partition volumes. I tried verifying and repairing the disc but that didn't do anything. The only buttons available are Verify, Info and Burn. What do I do to use the drive again?

I am using a Mac Mini, Which is having a capacity of 74.2 GB. Hardly I made use of 15 or 16 GB of that. As I felt some slowness, I tried running "Disk Utility". Recently I found that the free space is only 2.4GB, instead of around 55GB..
Disk Utility is showing
USED SPACE :71.8GB
If i am calculating all folders in "Machintosh HD" (Application, Library,System, etc..), it wil come around 14-15 GB only.

i was Erasing Free Space in Disk Utility, after a while I needed to Force Quit another program but I mistakenly quit Disk Utility and now it says I only have 3.1 GB space available when it should be around 270 GB available. I'm sure Disk Utility said it was 'Creating Temporary File' at this time this happened.
I'm now also getting a message which states I need to clear out space on my start up disk.

I had a presentation today, and plugged my MacBook Pro ('06 version, and 10.4.10) laptop into a projector. Right as I did that, things went a little crazy, the audio was coming out with hissing, it was running very slow, and overall just went from running great to disfunctional. It finally froze, and I shut it off. A couple of hours later, I'm failing to get past the blue screen during the start-up. When i run in safe mode, its just shuts off while i'm holding the shift key

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?

I just ran the Erase Free Space thinking it would help me with a bootcamp issue.
I had 70Gb free and I stopped it when I noticed i had 30 Gb free left. So I just lost 40 Gb of hard drive space. What happened? is there anyway of recovering it or did I just make a huge mistake.

I partitioned my disk using Terminal's diskutil. I decided i didnt need the partition anymore, so i deleted it (using Disk Utility.app) and added the free space to my mac partition. Basically, Finder and Terminal dont show the free space added back, and Disk Utility shows the space added back to the disk. I tried restarting, repairing disk (which coincidentally had an unrelated problem), repairing permissions, but the problem is still happening

Trying to resize and existing volume using disk utility on Leopard. Have a 1TB internal Drive with 1 Partition (extended Journal), not a boot drive this is just for data, now want to add another partition (2 Volumes), in effect shrinking the size of the original so I have 2 equal sizes.
So Far I have used 450GB, so there should be enough room to do this right? Although when I go through the process, I get the message 'not enough space on drive'.

I recently upgraded my Macbook Pro to Snow leopard. About 4 days later, my Mac crashed. When I tried to restart, it came up with the grey screen with apple logo and spinning disc. I have tried all of the resets. I then decided to try and re-boot from the SL install disk. When it asked me to choose a destination volume, however, there was none available. I tried disk utility, but there was no disk available there either. I then went back and tried to use the original install disc that came with the Mac...same results. It appears that my internal hard disk has disappeared. I wonder if i am going to have to replace the hard drive?

The Finder window shows that I have 302GB of harddrive space remaining, out of 500GB. The Activity Monitor and Disk Utility show I have 240GB space remaining, and my System Profiler shows I have 239GB remaining. I just deleted a bunch of old TV shows off of iTunes (about 40GB worth) to open up some space, but only the Finder changed (up to 302GB from 260GB) but the Activity Monitor, Disk Utility, and System Profiler haven't changed.
Now, I'll assume the Finder is showing the correct amount of space, but I'm wondering why the other utilites are showing the incorrent amount of space. I have a feeling maybe something was screwed up when I created a 50GB Windows 7 partition through Boot Camp a couple months ago.
I've attempted to Repair Disk through the Disk Utility and it says everything looks fine. Any solutions to this minor inconvenience? Or at least an answer as to why this is happening?

After then parade to Yosemite I ran into hard drive issues and my 2012 iMac will no longer boot but I ca boot to Internet Recovery. My latest plan was to do an OS reinstall to an external drive then try to recover items w/ target drive. In any case, when I choose reinstall OSX, it tells me I have to verify with Apple...OK...then continue....then it says select a drive to install OSX on but gives me no selection option? Just a blank white line? Both drives (internal and external) show up and can be accessed via disk utilities.

I'm having a pretty serious problem. I attempted to erase the free space on my HD, as I do from time to time, except this time it appeared to hang/freeze at the end, when it gets to the part where it creates a temporary file. I waited for several minutes and it didn't move. I tried clicking the skip button, but that did nothing either, so I force quit Disk Utility.
The problem is, it left the disk at "Zero KB" of free space, effectively making my computer inoperable. I was in the process of studying for a huge exam tomorrow, and am currently flipping out.
If it matters, I'm on a Macbook Pro 2.33 GHz Core 2 Duo, running 10.4.
I really don't want to have to reinstall the OS and import the old files, but my real fear is that I will have to do a fresh install of the OS.
