Help with Disk Utility error message.

I just ran the repair utility via the installation disk, and at first I got this:
Checking HFS Plus Volume
Invalid node structure
Invalid node structure
Volume Check Failed
Error: The underlying task reported failure on exit
1 HFS Volume
1 volume could not be repaired because of an error.
I ran it for a second time, and got the same message, only my Macintosh HD, which is listed at the side, had been renamed to disk1s2.
I then ran it for a third time and got this.
Checking HFS Plus Volume
Checking Extents Overflow
Checking Catalog File
Invalid Node Stucture
Rebuilding Catalog B-tree
The Volume Macintosh HD could not be repaired
Error underlying task reported failure on exit
1 HFS Volume Check
1 volume could not be repaired because of an error.
What does all his mean? How can I repair my disk? My computer is acting up. The cursor turns into the coloured busy symbol at the slightest thing. It can stay busy for really long, preventing me from doing anything. I then have to shut down and restart. I've also received the flashing question mark when trying to restart.

I'm open to suggestions! I am tired of it now too!
Anyway, why would everything be working OK before the update if my computer was so bad?
That happens. Applying an update sometimes makes the problems more noticeable.
Luckily, I managed do back up everything on my two external HDs with no problems.
What kind of backup? If it's a clone, it will have the same serious error you have now; unless it was done a while back, before any issues were there.
things seem to freeze up when I'm doing lots of multitasking.
Because you have serious directory corruption.
But maybe it's time for a new machine sooner than I planned?
This is repairable by you. It's possible a piece of hardware, think bad RAM, could cause this directory corruption.
Try running your Apple Hardware Test to see if it flags anything.

Disk Utility Error Message-Bootable USB/ExternalHD

I'm using Disk Utility at the moment to create a bootable USB/External HD ( I've tried both ) and nothing is working. It comes up with a error message. I have the retail Snow Leopard DMG and i'm doing everything correct user wise. It's just something is wrong with Disk Utility in my opinion..
Error message (60) restore failure.
So now my question is.. I's there a alternative for creating a bootable usb/external harddrive. CCC only allows for the copying of your Macintosh but I want to create a bootable drive. Please someone help fast.

Hello, have you used Disk Utility to Repair the External Drive?
Might try Carbon Copy Cloner...

Help with Disk Utility

I have a removable usb flash drive that I've been using for a while. Occasionally I need to erase it with disk utility to remove all of the past information it has held. This time around though the drive doesn't seem to be created (I'm not sure if I'm saying that the right way or not).
I've included a photo here:
http://northeasternxposure.com/help/drive.png
Normally there is the "983.0 MB VBTM . . ." drive with the "UNTITLED" one below it. As you can see the "UNTITLED" drive doesn't look like a drive, but has the icon of a document. And at the bottom it shows the capacity, yet none of it is available. This is why it won't mount. I've tried to redo it multiple times with no luck. Hopefully someone knows a setting or something that I should change to repair this problem.

I went into Finder and it could still see the drive, yet not access it for some reason. So what I did was log out and then back in and everything was working fine again. I've got no idea why that problem had occurred, but thanks for the quick responses.
And I always do remember to mark helpful and solved. Thanks!

Hi alexandros.c;
If after doing what Michael suggested you are still not able to repair your disk, you may need a more powerful such as DiskWarrior to repair it I have found that when the the disk has problems that the tools within OS X are unable to repair then DW usual does it.
If DW is not able to do it for you about the only other alternative is to reformat and start over again.
You should have a good backup before doing either of these solutions to protect yourself.

Disk utility error message

My daughter told me her Mac mini isn't booting up past the grey screen. I put in the install disk and started it up pressing "C" and used Disk Utility to attempt to figure out what's up. I got the following error message:
Could not repair due to underlying task failure on exit (-9972)
Does this mean the hard drive is toast? I don't have any HD repair software-with all my Macs I've never run across a problem that the boards here or Disk Utility couldn't fix for me. I don't know if she damaged the drive (she claims the cat chewed on the edge of the mini-sounds a bit like the "dog ate the homework"), or if it failed. It was purchased last year when Tiger was released, so it should still be under warranty. Any ideas about what I could try next?
Thanks

Dale, although the -9972 error is probably some serious data error on the drive, which can sometimes be solved by an Erase & Install of Mac OS X, the fact that the Hardware Test reports an issue probably means that the data error was caused by physical damage on the drive.
I have to say that I find your post(s) most unhelpful. It' true that the informatin contained in them can be useful, however, you could have made the effort to sort it for iMargB. The fact that you didn't, plus your posting of the exact same post in two different threads, makes me feel that you are in a hurry, and that you sacrifice quality to quantity. Trying to help as many people as possible is a good thing, however, we are here to help (or to be helped), not to overwhelm people with information, hoping that they will figure it all out on their own.
iMargB, the Hardware Test is not part of Mac OS X, it is a system-specific volume, which explains why it is included on your original disc rather than on the Tiger one. Your guess of using the latest OS's Install disc was a good one though, when it comes to using Disk Utility for example : attempting to repair a Tiger installation with a Panther disc is not a good idea, as it might damage it instead, because of the differences between Panther and Tiger.
Although I know little about the Hardware Test's error messages, the "Master" part is not what would worry me, as it could just be the position of your hard drive's jumper (which could be Master, Slave, or Cable Select). However, if the Mass Storage test is failing, I would suspect a hardware issue with the drive itself. Hardware Test is known to miss a few things sometimes, but the reverse isn't true. Thus if it reports a bad drive, I think it is safer to assume that there is an issue than to assume that Hardware Test is wrong. Moreover, the "Invalid Node Structure" is very likely due to physical damage (as I already said), therefore, zeroing out all data and reisntalling Mac OS X or using Disk Warrior could be very temporary fixes.
If you have a FireWire cable, I would suggest booting your Mini in FireWire Target Disk Mode to retrieve as much data as you can, with another Mac such as your iMac or iBook. Instructions can be found here. There may still be a chance that the other Mac could see the drive, so not all your data would be lost. Then, I would take it to Apple for repair, as the drive could be failing.

Help! This is a brand new MacBookPro, I've only had it a couple of days!

So far I have never had any problems with them personally so I don't do an Erase & Install.
I'm sure we're all happy for you although problems do happen. Problems with the installation and even hardware problems. Thing is, often these issues aren't apparent until some time later.
The way I see it, the time and effort required to do an "Erase and Install" (which include a zero write to the drive) is a known… about 3 hours. To my mind, even there's a remote chance that this stops a potential problem in its tracks before it's a problem it's worth the time spent. 3 hours over the lifetime of a Mac OS X installation is not a lot to give up.
Additionally, by zero writing to a drive, it does allow you to see if your drive is on one way performing correctly. All four of my 300GB drives in my Mac Pro wrote zeros within one minute of each other. I know these drives won't have issues when being told to write a ton of data. Whithout doing this I would never know.
Now I did the same thing with my parents' 750GB drives and one finished in 3 hours and the other was still going at 5 hours. Now you can't tell me there's not something up there. So at what point would you like to have found that out?
How much time, let alone money, does it cost to do something later on?
Just like tools like Monolingual. How many issues with updates are caused by such tools? Again, how much time is lost to debug and maybe fix such issues? Thing is, we don't know although if you had a customised installation from the outset it wouldn't matter as you wouldn't be using such tools.
But hey… everyone's got their own opinion. All I know is that my systems always seem to go better and faster than every other Mac owners I know.

Disk Utility Error Message - Missing EFI + MediaKit

Previously setup was with 2 partitions, one for normal use while the other had the Lion Install ESD on it, used when I installed some time ago. The other day my machine suddenly shutdown and when I started it, it stated that the Lion Install ESD partition was corrupted.
I created a new Lion Install ESD partition and made a clean install (I was going to do so anyway).
My machine is booting fine, but it acts funny in the Disk Utility. First, an overview of my disk:
However if I attempts to "Verify Disk" on my disk (not on a specific partition) via the Disk Utility the following error is shown:
Even more strange is when I attempt to let the "Macintosh HD" use maximum space on the disk. It is currently sized at 230GB, but if I use the Disk Utility to increase it to say 231GB it reports the following error:
However, the space is clearly unused. And if I simply drag the partition down to use all the space the error will not prompt but nothing will happen.
In the time between my first install of Lion and the recent shutdown I had installed rEFIt after attempting to run Ubuntu, however it was quickly uninstalled again with no issues in the following months.
So, any clue what is going on with my disk?
Thanks in advance!

Maybe some added info will help. I have no problems starting the machine and using it. It's just that when I went to fix permissions and accessed disk utility from the hard drive to do it, I got the error message noted in my first post. I am wondering why that is, since it didn't happen before. I did use my 10.4 OS disk to start up just so I could fix permissions (that did fix permissions), but trying to repair the disk (to hopefully fix the problems I was having when I tried to access disk utility from my HD) didn't work. That's when I got the second error message. Is that because I've upgraded my OS to 10.4.11? I did that w/the Apple on line upgrades, so I don't have a 10.4.11 disk. Is that the problem? Also, do you know if there is a 10.4.3 upgrade? Thanks.

Disk Utility - Error message...how do I fix this???

My powerbook has been running a little sluggish, so I decided to run Disk Utility and the following message appears:
First Aid failed.
The underlying task reported failure on exit.
Can anyone let me know how to solve this???

Hi, ejji. Without knowing which routine you were running, it's pointless to guess at what the problem might be. Try the following:
Boot the Powerbook to your most recent retail OS X installer disc; use Disc 1, if it's a set. Note: (DO NOT use your Intel iMac installer disc(s) on the Powerbook.) Open Disk Utility from the Installer menu. Select the hard drive and the First Aid tab, then click "Repair Disk". This may be the same thing you were doing when the error message appeared before. If it is, repeating the procedure won't do any harm and might do some good. If you don't get a similar error message this time, repeat the process until DU has given you two consecutive "Appears OK" verdicts. If that doesn't happen after half a dozen runs, you'll need either to buy and use a more powerful disk Utility like DiskWarrior or TechTool Pro, or erase the drive completely and reinstall everything on it.
If you do get two consecutive "Appears OK" outcomes from the Repair Disk routine, try the Repair Permissions routine next.
Post back with results and/or additional questions.

Help with Disk Utility and disk repair

I just ran disk utility to verify my hard drive and the report says this:

After saying that HFS volume needs repair, it won't let me repair the disk. That button is grayed out in disk utility. If I boot the computer from my OSX install cd and repair it that way, will it erase all of my data on my hard drive? Any ideas?
20" iMac 2.0 GHz Intel Core Duo Mac OS X (10.4.9) 60 GB iPod Video

To repair a startup volume you must boot from your OS X Installer Disc:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

I tried the Help menu, as well as Sherlock to search AppleCare but couldn't find a thing.
Any ideas?

Disk Utility Error Message for Firewire HD: Could not unmount disk

I have one internal HD with 10.4.2, another with 9.2.2, and an external firewire with 9.2.2. Sometimes the firewire does not show up on my desktop, or when I try to copy files onto it the beachball spins endlessly. When I try to reboot holding down the Option key, the firewire HD does not show up.
I ran TechTools 4.05 (while booted from my Tiger HD) on the firewire HD. Everything checked out.
I tried running Disk Utility on the firewire. The first time this is what I got:
"First aid failed. Invalid key check. Volume check failed. Error: The underlying task reported failure on exit."
I ran Disk Utility again:
"Repairing disk failed with error. Could not unmount disk."
Any suggestions would be appreciated.

Your firewire disk is damaged. Try that: restart in safe mode (pressing SHIFT after the chime). Wait for complete boot. Plug the external HDD. Try again with Disk Utilities. Wait the report. My advise is to check its integrity. Try repair. If nothing works, try with DiskWarrior (the best utility).
If DiskWarrior can't do the job, you – definitely have a damaged hard disk.

Can anyone help with the following error message?

Any help you can give would be greatful.

Can you help with this serious error message?

I have Premiere Elements 8. I tried to open some .prel that I have made and now I get this error message: Projects created with Adobe Premiere Pro and Adobe Premiere Elements are not compatible. Please use the appropriate application to open this project. What gives?? Also, as usual, Premiere Elements 8 crashes after I have accomplished one lousy thing, so I have to constantly open project and save. Now I can't even open a project.
Thanks for any help you can give me.

Holy cow! Something is seriously wrong here, lilthea!
What model of camcorder is your video coming from and what format and resolution is it?
What project settings did you select when you set up your project? (You can see them under Edit/Project Settings.)
Version 8 was not the best version of the program ever produced. In fact, it was one of the worst, when first released. But if you downloaded the update (from Help/Check for Updates) and the rest of your system is stable, you should at least be able to edit video from a miniDV, HDV or even AVCHD camcorder.
If you truly can't do ANYTHING without it crashing though, there's something much, much deeper going on that a bug in your program or its set-up. (This is why I need you to be as specific as you can about things!) If things are really that unstable, it could indicate malware or viruses or possible corruption of the operating system.
I sometimes recommend a program that I use every week but that some people object to because it's Chinese software and has been accused of stealing virus definitions from other software companies. But it's got an easy interface. Just select Deep Care, click the go button and then select the option to clean. In my opinion, it makes your operating system as good as new. But there are some people who disagree, so that's my personal recommendation only.
Download the free version from here:
http://www.iobit.com/advancedsystemcareper.html
What you're dealing with could be problems with your source video -- since I don't have enough information to say either way. But, assuming your video came from a miniDV, HDV or AVCHD camcorder and that you've properly set up your project to those specs, a tune-up using Advanced System Care might be worth considering.

Help with "Testing Failed" Error message in iWeb09

I bought the iLife 09 upgrade purely so I could publish to my own domain server. I have a MobileMe account and iWeb09 publishes fine there--no problems.
My domain name is hosted on a Windows NT server. The admin is willing to help, but I was hoping someone could point me to documentation for this error:
"Testing Failed.
Unable to write to server. Verify your settings and try again."
If I ftp to the site in a terminal window and do a put, I can write to the site. Obviously, I could at some point, because it servers the "dummy" page I put up, but I tested again in case my permissions had changed.
I looked at the "Publishing to Windows-based FTP Server" but it does not seem to describe this error.
BTW, I pay AppleCare for support, but when I tried to get support documentation from them, the tech said they "can't help" with this part of iWeb and hung up on me--the call lasted exactly 90 seconds.
I am hoping someone out here will know where the errors are documented or will be able to help me figure it out.

I waded through the posts for iWeb09 and came across a recommendation for Cyberduck (www.cyberduck.ch), so I tried a copy. Works like a champ. Unlike iWeb09, all I had to do was type in my server name, user name, and password to open the connection. Then I published my site to a folder in iWeb and uploaded the folder in Cyberduck. Cyberduck had no problem writing to the server.
I still would love to know why iWeb can't write to my web server.
