Verifying Disk with Disk Utility

In Mavericks, when I verify the disk I sometimes get the output with "... appears to be OK" but pretty often the verification just stops with no output.
Example:
Code: 
Verifying volume “Macintosh SSD”
Checking file system
Performing live verification.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking multi-linked files.
Checking catalog hierarchy.
Checking extended attributes file.
Checking volume information.

Is it normal or there's something wrong with my drive?

Thanks
 
You mean it just stops there and never completes?

Try a command-r boot to recovery and run Disk Util from there and do a repair disk.

Yes, it stops there like it's finished. the blue progress bar goes away but I get no final output like "appears to be OK" or something else.

Verified in Recovery mode and it worked like it's supposed to. Did ja repair disk just in case too and another verification after that. Both time got the green "OK". Rebooted back to OSX and tried to verify disk and again - this time stopped at "Checking extended attributes file".

Reboot and press COMMAND and S simultaneously while rebooting. This will take you into Single User Mode, which is basically an extension of Terminal, just no UI at all, and is run as root. Type:

fsck -fy

Press enter. It should then verbosely check the hard drive and let you know of the result at the end. Expect a few lines with two ** next to them. If the result says "*****FILE SYSTEM WAS MODIFIED**** (or something to that effect), run fsck -fy again until the end result says "FILE SYSTEM IS OK" (or something to that liking).

When all is done, type reboot, then you'll be back into the familiar UI within minutes.

HTH!
 
I know what the OP is stating as I have seen it a few times recently. The DU finishes without changing anything or finding any errors, just doesn't report the final findings. It just ends without writing the final outcome of the action to the screen. Rerunning the action will sometimes correctly report the ending status but not always. It is just like it abruptly end without reporting the results. I think it is a minor big in DU.

Yeah, seems so.

It would seem so. If running verify/repair from recovery is not turning up any errors, I think it is safe to ignore until this gets fixed.

Agreed and know there are no errors on my disk, it is just something I have noticed and let go is that it does occasionally not report anything. Generally the next exact run behaves correctly, so jot is a way I believe that DU is currently operating. It is and never has been something I use on a regular basis so I just let it slide when I noticed it.

Mine stops at "Checking extended attribute files."
 
Having the same exact issue, and have been since installing Mavericks.

In Disk Utility UI, I need to run "verify disk" several times before it finally gives me the message that HD seems to be OK.

I'm not sure if the process doesn't complete, or if it simply doesn't say the disk has been verified. Nonetheless, running "verify disk" 2 or 3 times finally seems to run the process through completion and states that the process has been run successfully.

On a slightly different note, has anyone been able to resolve the laundry list of errors when verifying disk permissions? I know there have been issues with iTunes that causes a majority of permission errors. But recently I have been seeing other errors unrelated to iTunes, including "installed printers", "var/private", etc. However, every time I try and repair disk permissions, the errors seem to persist. I've tried repairing permissions in Recovery mode, and even after enabling root user. Nothing seems to work.

Any ideas?

I have some permissions that never seem to go away as well. Mostly iBooks, and Printers.
 
A known issue, an appearance bug

It's a known issue, an appearance bug that sometimes affects Disk Utility – in a variety of ways – when the HFS Plus file system for a startup volume is locked down for live verification.

There's variety – in some cases, repetition and/or disorderly appearance – but the most common symptom is non-appearance of the conclusion from the check.

Please

Read output from Disk Utility alongside the following file, which can be browsed with Console:

/var/log/fsck_hfs.log

Where the green part-assurance (… appears to be OK) is missing from Disk Utility:

  • you will find the required line, the conclusion, present in fsck_hfs.log

Doesn't say. Non-appearance.

Please consider posting to a separate topic; we can keep this topic focused on an eventual conclusion to the bug that was observed by the opening poster.

I ran a permissions repair and allow the program to sit for a min or two before I run the verify. Seems better than it was but I still think there is a problem as the rest of are experiencing as well.
 
Have you checked the Log message? Also noticed the above - came across Support Pages suggesting one checks the Log. It confirms things having finished, usually.
 
Look at /var/log/fsck_hfs.log

Same issue here with Mavericks, the Disk Utility feedback does not tell the truth. This is clearly a bug. The truth can be found by browsing the log file.

/var/log/fsck_hfs.log​
 
Hmm... if it appears to STOP without being finished, I would think that it is NOT FINISHED, and is trying to repair something.

This will be my 5th reply of the day using the word Console.

Okay, so do this.

Launch Console, put it on the left side of your screen (so you can watch it).

Next, fire up Disk Utility, put it on the RIGHT side of your screen (so you can be watching both Disk Utility, and Console at the same time.

Run Disk Utility, and WATCH all the Console messages.

There will lie your answer.

If the console says it's finished, then it is. If the console is stalled, or saying something else, then you're not finished, and you have been Aborting the disk repair prematurely all these times.

Alternatively, start up in Single User Mode (I think it's "Command + S") and then you'll start up with a black screen with a bunch of greek on it. When it's done loading, at the bottom it will say to run FSCK if you want to repair your disk.

The exact command to type in is:
/sbin/fsck -fy
(and hit the enter key)

Then, your SuperUserPowers will fix your disk.

What I just told you to do is about half-way down this Apple page here:

Good luck!
