Disk utility first air problem information

I ran a disk utility first aid and i recieved an error message, what should i do? It reads
Volume bitmap needs minor repair
Checking volume information
Invalid volume free block count
(it should be 2073091 instead of 2072969)
Repairing volume
The volume Macintosh HD could not be repaired
Error: The underlying tast reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
What does this mean how can i fix it?

Hi Amanda,
Although it's not cheap, Disk Warrior can repair most types of hard drive directory damage. Your other alternative is to reformat the drive (losing all data) and reinstall everything.

Older OS Disk Utility first aid use on newer OS

I have an external drive that has a bootable backup (10.3.7) of my Powerbook. The Powerbook currently is out of commision. I plugged the drive into an iMac and found the drive would not mount. The iMac's OS is 10.0.3. Can I use it's Disk Utility, First Aid to repair the error on the backup drive? The iMac says that there is an "Invalid node structure."

No, because Disk Utility cannot repair an "invalid node structure" problem. Disk Warrior (www.alsoft.com) may - and I stress "may" - be able to repair the directory, but if not you will need to reformat the drive.

Error: The underlying task reported failure on exit'
This was a nightmare for me to fix, but after I learned how it was easy. If you get this error and you have not already restarted your computer, open you sharing preferences and make sure you ahve not set the everyone group to 'no access'. If you have change it and retry to run the permissions repair. If you have already restarted you will need to startup using your install DVD and then open terminal. In terminal type the following to fix your permissions.
chmod 775 /Volumes/'Macintosh HD'
This will change your permissions and you should be able then to get past the grey screen.
Hope this helps someone.

Hi everyone, I believe my permissions are the problem.
I let someone change permission settings to share music files on their hard drive and mine and another mac (3 in total) yesterday. I seemed to work. I can't remember if I then shut down my mac or just closed it. Anyway last night I was trying to organise the music files and burn them to dvd. I also tried change the permissions as some of the files were read only. I though it worked. It seemed to be burning and the screen saver came up, I clicked to exit screen saver and it just went to black and back to screen saver and i couldn't go any further. I had to hold down the power button to turn if off.
I tried to turn it on and now it's stuck on start up gray screen with the loading wheel thing? just loading forever.
I used disk utility, verified volume and repair disk are ok, but verify permissions and repair permissions, I get an Error message "the underlying task reported failure on exit"
I opened terminal and typed in what tryjezus1 said,"chmod 775 /Volumes/'Macintosh HD'" and pressed return. Not sure if I should have pressed return or if I should have just closed the window?. Anyway I'm still stuck.
I only have the mac since march so I believe I still have phone support, but if anyone can help I'd like to try and sort this out myself.

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
Quit and you should be able to install OS X now with your Apple ID and password.

2Can't burn a DVD using IDVD nor Disk Utility first time user-what is wrong

T he recording device reported the media error: Power calibration area error. (0x73, 0x03.)
IDVD Version 6.0.3
Emac- OS 10.3.9--- in the owner's manual it DOES state my emac can burn DVDs. Is this correct?
I am using FujiFilm DVD-R . Never used the DVD apps or burner before. I PRAM'ed 3 times. Also did 6 CD audio burns to check the drive. Is it the media-- Fuji does not work? I used Office Depot generic for audio CD-Rs.
I keep getting this error message after about 20 minutes of programming the DVD-- then it ejects with this message:
"The recording device reported the media error: Power calibration area error. (0x73, 0x03.)"
When using the IDVD application to burn my slideshow onto a DVD; Then I contacted Apple Care and I was told to use Disk Utility to burn my DVD in lieu of IDVD not working.
I converted my slideshow into a .dmg format; all was verified successfully. Then I receive this error message when attempting to BURN DVD:
"STOP The device drained its buffer without burn under run protection"
I made a WONDERFUl slideshow-- of only 17 slides-- confirmed I have plenty of room on hard drive and et al on the "disk information". I have attempted since May 7th to get this DVD to burn my slideshow. PLEASE HELP ME!!! I have deadlines-- now it is for Tuesday May 15th. Please alert me to an alternative until I can get my Emac working properly on what I can do to make copies of my slideshow ASAP. Thank you.
Now I looked thru your ERROR message archives and found NONE to match mine. What do these error messages mean-- is my Emac not working? This is first time ever I tried to use IDVD and IMovie and Disk Utility--- so the first impression is VERY VERY VERY bad for Apple's "easy to use for first time customers"....
Oh to add information-- I DO have an external DVD recorder-- have yet to even see how to hook it up to my Emac-- if this is an alternative to meet my Tuesday deadline-- PLEASE let me know-- how do I burn a copy of my slideshow into an external DVD recorder?

Also did 6 CD audio burns to check the drive. Is it the media-- Fuji does not work?
Your drive is actually TWO devices - one set of optics and laser burns/reads CDs, another set of optics/laser reads/wtites DVDs. The fact that your drive can burn CDs doesn't mean it is working for DVDs.

You might want to get back to Applecare and expalin again the error messages you are seeing. They really don't involve iDVD.

"STOP The device drained its buffer without burn under run protection"
You either have a media problem or you have a DVD burner problem.

Disk Utility: First Aid: "Repair Disk" grayed out when i select the HD

I'm getting the flashing question mark folder icon at startup and my Mac never does start. I'm trying to run through the repair suggestions on this forum and on the support pages but I can't do much of anything with the disk utility. (I've done the reset PRAM step and I've tried reselecting a startup volume both with the startup manager --HD wasn't shown as an option-- and by holding down "X" on startup... neither helped.)
Under first aid, verify disk permissions, i get the "no valid packages" error message. But "Verify Disk Permissions" is the only button available to me when I select my internal hard disk. The support pages say to "Repair Disk" but I can't select that option.
I've tried to reinstall the OSX from the CD, but when the installer asks me to select a destination volume, nothing is available to select.
I am running version 10.4.something at least. My CD is the one that came with the computer a couple of years ago. I have one of the early Intel Macbooks.
I have an appointment at the Genius Bar after work tonight but I'd love it if I could fix this baby sooner.
Am I hosed?

OK- Try a Single User boot- hold command +s while starting, and try and repair with fsck.
-Startup in Single User mode.
-At the command-line prompt, type */sbin/fsck -fy*. 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 again, 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).
-When fsck reports that your volume is OK, type *reboot* at the prompt and then press Return.
-Your computer should start up normally and allow you to log in.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck

No Disk utility app or System information app or AirPort Utility app

since upgrading to Maverick these System apps (Disk utility app, Activity Monitor app, Systems Information app and Airport Utility app) are all in shadow with a cross through them. why? at first i waited becourse i thought apple would update but it seems to be just me.

When you upgraded, were they in their default locations or did you move them to a different folder? Updates don't go looking around the computer for the Apps. If they are not in the default location they are skipped.
You could try installing the 10.9.2 combo update. That might update them.

Well I had to make the copies for my presentation-- so the cheapest I could find in my area was Walgreens-- 39.99 for ONE COPY of a DVD! So I paid $70.00 and the clerk made 4 copies for me;-) So thanks Walgreens!
Now-- my Mac-- I could not find anything on shelves at Walgreens or Office Depot but the FujiFilm I already have... So I now have time to look elsewhere.
I did PRAM my Emac 3 times-- I tried these things also:
1)Saved the IDVD- .dmg format to QuickTime .mov
I uploaded to google video.com or whatever-- they use their own software-- .gvp file and player. All was successful (even now on YouTube-
2) I then made another version in PowerPoint and saved it as an MPEG
Also for below-- I lowered the burn rate upon the 2nd try to 1x-- took one hour or more (I went to get a root canal... then exfoliate... then I came back;-)
Also tried different .mov from the web-- a great whale shark video that was only 49mb. My presentation is 120 mb. So I was just thinking-- make it smaller; burn slower.
3)I did try to burn from IDVD, Disk Utility and then the drag and burn/click method on the desktop-- put a blank DVD in-- drag the .mov icon to the blank DVD -- write a title for the blank DVD- formats it / Drag to trash-- Burn icon comes up/ Clicked it-- waited 20 minutes and received:
"Error: Error occurred while burning the disc. This disc can not be used."
So I put in another blank Fuji DVD-- just in case. Same error message-- so I am hoping it is the DVD itself and not the SuperDrive.
4)Also-- I tried to do audio CD burn-- just to make sure about the drive-- all was successful and I did a back up of my Itunes files-- 6 CDs they burned (they meaning "the Gods of Mac OS" ;-0 My audio CDs are Office Depot CD-R 52X700mb/ So the generic is better for CDs on my Emac that I know;-)
So I will use my weekend to try other DVDs-- and I have the safety net of Apple Care-- but then just realized-- my Extended Care plan is OVER at May 30, 2007!!! I called to ask to EXTEND it further-- I'll pay whatever-- NOPE-- 3 years was max on this contract. So any repairs I have to pay for after May 30th-- ISN'T THAT JUST THE WAY THE WORLD GOES? The DAY after your warranty on AnYTHING-- the thing goes kablooey?
But I still have days left--- and I know of a good Mac Repair person in area-- but it is just so darn difficult to move my desktop Emac (I got the GLASS monitor to save $300 or something) Weight Lifting is what it is-- weighs about 45lbs or more.
But it seems it may be the media I am using if the CD burner is working, right?
I can update-- if you want me to email direct-- just give me a note (my email is listed). Thanks all!!! I just want to impress everyone of how tenacious I am to find that my Emac is FINE-- it is just ME that is warped;-)

Boot Camp Assistant & Disk Utility First Aid failing?

Hi,
I am trying to open my download of 3DS Max for an assignment but the following problems are stopping me:
1. The message ' The document "Autodesk_3ds_Max_Design_2012_English_Win_32-64bit" could not be opened. The file is too large'
2. After advice on this forum I tried to create a partition with Boot Camp Assistant (of 32gb). But this failed and told me to repair the disk with Disk Utility.
3. Disk Utility gives the following messages after I have tried repairing and also verifying the disk
Would really appreciate some help!
Thanks

Reinstall Leopard, but first use the Leopard install DVD Disk Utility to reformat the HD to one partition. See:
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh14.html
It's for Tiger, but applies for Leopard as well.
WARNING, you must have your data saved somewhere else.

Disk Utility Errors/ Mail Problems

My mail was working fine the other day, but suddenly it won't connect to any of my email accounts (gmail, university email account, etc). I tried installing Thunderbird and read my messages through that but it still won't work.
Additionally, skype stopped working too. It said I could connect but it would show that no users were online, when they were infact online. However, I reinstalled it and it solved the problem. But mail still won't work...
I looked at my firewall settings and they seemed ok.
The internet/network connections are working completely fine. I can browse normally with Safari. The only things that have changed are Mail and Limewire. Limewire no longer connects properly and mail can't seem to connect to any of my accounts. No preferences have changed to my knowledge. I even tried dragging the preferences folder to the desktop and let the preferences go to the default, however, Mail still did not work
AND I decided to run the processes in Disk Utility and it wouldn't even finish verifying the Disk! It said this:
Verifying volume “macintosh hd”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Volume Bit Map needs minor repair
Checking volume information.
Invalid volume free block count
Invalid volume free block count
(It should be 6027767 instead of 6027735)",2)
The volume macintosh hd needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked

HELP!

Boot into Single User Mode (command s) and run the fsck. The instructions are there when you get to the prompt: /sbin/fsck -fy
Don't use an older version of 10.4 than 10.4.6 to be safe, ie if you have 10.4.0 DVD it is recommend to NOT use it. There are 10.4.3 and 10.4.6 DVDs of Tiger.
Best: have and use an emergency boot disk on another drive, just need a small 10-20GB partition and update it with minimal Apple updates, and run your disk repair utilities from there.

My early '06 iMac won't boot, just clicks with question mark on screen. SMC reset, Pram reset can bring it up, works OK for a day or two, then back to no boot. disk utility finds no problem with disk

anytime I get it to boot, it works for a day or two then goes back to the Question mark screen.

Hi! It could be HD issue. You should back up your data in the computer first when you can boot to normal desktop. boot to install disk to run disk utility - if it got error over there, you should bring the computer to repair centre to fix it. You also could try to erase with zero out and install again And see will that be fix the issue!

Disk Utility says no problems but Diskwarrior disagrees

Need some advice. I ran Disk Utility yesterday to verify my drives before upgrading to 10.4.4 on my Dual 2GHz. It came up with some errors but said it couldn't fix them. Went to Diskwarrior which also said it couldn't fix it. Did a safe boot which is supposed to force an 'fsck' but the system never fully booted from that, probably failed at the fsck (the fans turned on full blast at the grey bootup screen then eventually powered off by itself). When I rebooted, I ran Disk Utility and it now reports the drive is fine. Diskwarrior still scoffs at that though.
Disk Utility said something about File Allocation Table mismatch.
Diskwarrior said the directory structure could not be repaired.
SMART says the drive is fine.
TechTool Pro reports a Bitmap mismatch and could not repair the drive.
Thing is, I don't see any problems with the drive at all. System boots fine and there are no corrupt files. It's a 3 month old 300GB Seagate so I don't think it's a hardware problem. But I've had some kernel panics related to my video iPod (the one where the G5 kernel panics if you have low space left on the iPod) which is where I'm guessing this all started from.
I've left it for now with Retrospect backing up the drive to a new external 250GB drive I had to buy just for this. I was planning on formatting the problem drive, testing it again and then restoring the Retrospect backup. (The only issue I've had with Retrospect is I Duplicated the problem drive to that new drive and had about 4000 files with different dates. I'm hoping that doesn't happen using the Backup function instead.)
Is this the right path? Or anybody think it could be a hardware issue? I've never done a full system volume backup with Retrospect, will I run into problems making the restored drive bootable again? And last, are there any other programs I should try?
BTW, I thought Journaling was supposed to fix all this!!

My MacBook Pro 13 inch makes a clicking noise from the hard drive and can not start up in safe mode and normal. I then ran disk utility in recovery mode and disk utility shows no problems with the hard drive. What is the problem?

Please help me, I have a mid 2010 Mac book pro with a toshiba mk3266gsxf harddrive. It started making a clicking noise and then my computer crashed. I proceeded to boot in safe mode, but it doesn't work. When I ran disk utility in recovery mode, it showed no problem with my disk. Does any one know what the problem is?

Sounds like a mechanical problem with the drive and it ruined the sectors where the Macintosh HD partition (and OS X, and files and programs) reside, but not your Recovery HD partition.
If you held command option r while booting, that's Internet Recovery and it's loaded via the Internet, not via the Recovery HD partition on the boot drive, so that could mean the drive is dead mechanically or there is another issue.
In either case the drive will likely have to be replaced, it's a matter of what occured to where and the drive state if you can recover data or not. If you made recent backups then your fine.
My computer is not working, is my personal data lost?

H.D. Clicks When Booting But Disk Utility Says "No Problems"

My friend installed a new 300 gig Seagate on his G4 a couple of months ago. It has worked fine until now. Suddenly, it won't boot up from the HD -- just clicks. He gets the spinning ball and it freezes up. HOWEVER: (1) The icon does appear on the desktop and (2) When he starts up from the CD and runs Disk Utility, D.U. recognizes the H.D., checks it successfully, and reports "No Problems Found." He can hear it spin up and everything just fine when he is checking it with Disk Utility.
So, it seems to go into the "clicking and spinning ball syndrome" only when he is trying to boot up from it. Any ideas? Thanks!

Before you go to Lion, just a reminder. I know you recently moved up to Snow Leopard. Be sure that everything you were running in Leopard, and now in SL, will work for you in Lion.
Remember, Rosetta and all PPC apps are gone (Word 2004, some versions of PhotoShop etc) Check the compatibility list before you ditch SL.
As far as your Disk Utility problem, how hard is it to reinstall SL?
I've taken a screen shot of my Utilities folder to show you what you are looking for. The Utilities folder as mentioned above is in the Aplication Folder (or you may have pulled it out to the side bar as well, in which case there will be an icon and the word Utilities in Places in the side bar.
