Something's wrong with my hard drive, and disk utility can't repair it...

Lately my MacBook Pro has been running really slow, so I ran Disk Utilities to see if it could fix it. However, when I ran it, the following is what I see. Would someone help me interpret what's going on? Thanks.

Two things. First for the permissions check, reinstall the 10.5.2 COMBO update and repair permissions. That should fix things. Alternatively, search these forums for ACL, sort by date, and read the responses and the article Apple posted three months ago: http://docs.info.apple.com/article.html?artnum=306925
Second, for the *Incorrect number of file hard links* error, follow smithrj's advice. If DU can't repair the disk, you'll need something stronger, such as DiskWarrior.
BTW, please update your *My Settings* profile info. It still shows that you're running Tiger.

IMac Finder cannot see external hard drive but Disk Utility can

I have a WD external hard drive and it has been attached to my iMac for a year or two. About two months ago I upgraded to Lion 10.7.5 and hard drive still worked. Then suddenly about a week ago the iMac no longer sees the external hard drive in Finder.
I have connected the hard drive to the iMac with different USB cables and into different ports and it makes no difference so deduce there is no issues with the cables or the ports. I have connected the hard drive to an old Macbook and it can see the harddrive and read some of the info but I really need the hard drive attached to the iMac as I store all my music and photos on the external hard drive.
I read another thread and someone asked if you can see the hard drive in Disk Utility. I tried this and Disk Utility can see the hard drive.
What does this mean? Any suggestions as to how to get the iMac to see the hard drive so I can access the data on it?
I dont really know how Disk Utility works therefore if that is any help to me.
thanks

Open the Finder.
From the Finder menu bar click Finder > Preferences then select the General tab.
Make sure: External disks is selected.

Trouble with external hard drive and disk repair

So I save my music and photos to an external hard drive. The drive is partitioned to also be the back up for my Time Machine. I live in an old house with the electricity for my MacBook Pro and the external hard drive coming from a wall plug which drapes scrape over when opening and closing, occasionally moving the plugs to the point of cutting off the electricity. Sometimes when that happens, the MacBook Pro won't read the external hard drive and I have to restart the computer for it to read the HD.
Well, this seems to have happened again, only this time it wasn't reading the HD when restarted. I Opened the Disk Utility and did a verify disk, and was told that I couldn't save anything to the drive, but to access the files that were on there. So I attempted to do a disk repair. What happens at that point is instead of getting the solid blue line indicating the repair is happening, I get the barber pole blue line indicating it's trying to access the HD to begin repair. This goes on for hours at a time without the repair taking place.
Can anyone out there give me a "for Dummies" overview of how to get the Disk Utility to repair things?
Thanks.

What I was trying to tell you is that all the music and photos that are on the same drive as your Time Machine backup must also be backed up elsewhere. Unlike all the stuff on your primary (internal) hard drive, those photos and music are not backed up at all unless you have copies of them on a different drive. If your Time Machine hard drive should fail before you do that, they'll all be lost. So copy all the music and photos to your second external hard drive as soon as you are able to do so.
I generally consider the nuisance of backing up extra hard drives to other extra hard drives burdensome and annoying enough so that I always upgrade my primary (internal) hard drive whenever I begin to run short of space on the one I'm using. Now that it's possible to get 750GB and 1TB internal drives for MBPs, I'll get one of those as soon as my present 250GB drive fills up to about 80% of its capacity. I don't want to lug around an external drive in order to have all my stuff with me when I'm away from my home or office — I want it all on my internal drive, and I want to be able to back all of it up at once to an external drive of the same or a larger size. At least until I outgrow a 1TB drive, and I think that will be a while.

DiskWarrior and Disk Utility can't repair volume after 10.4.6 upgrade

I appreciate any advice on the following problem:
After installing the 10.4.6 update On April 4 (which installed just fine), I did my usual post-installation system maintenance including repairing permissions, running CRON scripts and cleaning the caches. I got a strange Apple Script error that flashed on and off the screen (too quickly for me to document) while I was cleaning the caches, then the process finished. Then when I used DiskWarrior as part of my usual maintenance, it "stuck" while saying that the process was slowed because of a disk error. I waited for an hour, and it never completed. I then restarted using the OS install disk, called up Disk Utility and selected Repair Disk. This is what I got:
Verifying volume "Macintosh HD"
Checking HFS Plus volume
Checking Extreme Overflow file
Checking Catalog file
Invalid node structure (in red font)
The volume Macintosh HD needs to be repaired (in red font)
Error: The underlying task reported failure on exit (in bold red font)
1 HFS volume checked
Volume needs repair (in bold red font)
I cannot repair this problem using either DiskWarrior or the OS installer disk with Disk Utility. In addition, I was unable to archive & install the system while using the OS install disk! I have tried repairing permissions and using DiskWarrior and the OS Installer disk again with no success.
I am able to work on my Mac, but things seem slower and I get occasional oddball errors that make no sense. A few times, applications have quit unexpectedly when they weren't before.
Am I going to have to initialize the hard drive and reload everything?
Many thanks!

Mac G5 (dual 2GHz) Mac OS X (10.4.6)

I had a similar experience after installing 10.4.6.
The messages I got in Disk Repair were:
Checking Catalog file.
Illegal name (in red)
Illegal name (in red)
Keys out of order (in red)
The volume Rich's HD could not be repaired. (red)
Error: the underlying task reported failure on exit. (In red)
After a long time on the phone with Apple, we decided to reinitialize the hard drive. I have reinstalled the OS and am in the laborious process of restoring my user files and non-Apple applications. What a hassle! And I am not even sure all will be restored to proper functionality.
Don't know if either yours or my disk failure are related to 10.4.6 but Apple better watch closely for user feedback. These are potentially disastrous problems for users if they have not backed up.

Something's Wrong with my Hard Drive

I recently tried to install Ubuntu on my Intel Mac Mini. This ended in disaster and left my machine unable to re-boot into OS X. I finally figured out that I could bring up a boot menu by holding down the option key (derr). I then tried to partition my hard drive using Boot Camp so I could install Ubuntu that way. This caused an error message that told me to run the disk utility because my hard drive needed repair. Disk utility does not let me repair the hard drive, only verify it. I did this and it came up with the message:
Disk Utility stopped verifying “Macintosh HD” because the following error was encountered:
The underlying task reported failure on exit
in the dialog window it says: "Volume bit map needs minor repair" and "invalid volume free block count". I can only speculate as to what that means, the bottom line is that I can't partition my hard drive. I tried booting to the OS X startup DVD but the option key only brings up my hard drive as an option to boot to.
Any suggestions would be greatly appreciated, I'm stumped.
Mac Mini Intel Mac OS X (10.4.10)

I would just like to add that I ran a partition inspector and it came up with this result:

I don't know if this will help, but it can't hurt.

Hard Drive and Disk Utility Failure on Macbook Pro

Ok, so I've had this Macbook Pro since Sept. 2006 and I upgraded the operation system to Leopard about a year and a half ago. I've had no problems until now.
A few days ago I did a software update for the OS, and didn't seem to have any issues. The next day when I booted up the computer, it was very slow in starting up. When it did start up, it only displayed the Macintosh HD and not my files, but a few minutes later everything else loaded.
When I ran disk utility it just said that the hard drive needed to be repaired. The error was talking about a file on the server that was supposed to be numbered 1002 and instead was labeled 501 (?)
Now my issues is, I can't find the Leopard disc, (i moved and I think I lost it?) and all I have is the original Tiger OS disc. I tried to reinstall the HD after backing up the files I needed onto my external. The Tiger OS disc will not work, it says there isn't enough space to be installed onto the computer. Also now whenever I turn on the computer the screen is grey with the apple logo, goes through the blue screen launch and just pops up the window that says "Mac OS can't be installed on your HD"
So right now I am frustrated. If anyone has any advice, please let me have it. Am I completely out of luck or could Apple help me? I no longer have applecare btw, it expired this past October.

"I upgraded the operation system to Leopard about a year and a half ago."
Your system info confirms you have Snow Leopard (10.6.2) installed.
Leopard (10.5) & Snow Leopard (10.6) are 2 separate OS systems.
You need your Snow Leopard DVD to repair the damage if that is the OS that is currently installed on your MBP.
"When I ran disk utility it just said that the hard drive needed to be repaired."
If SL is the DVD you cannot locate then you will need borrow a retail SL DVD & run the +"repair disc"+ setting or purchase one of the following to repair:
DiskWarrior
Highly recommended for *directory damage* repairs.
TechTool Pro
Multi-functional utility.
Drive Genius Multi-functional utility.
You will need to make your own decision on which to purchase. Read up on them on their websites because each does something a little different.
You must use the versions that are compatible w/your OS system & keep the utilities updated to avoid damaging/harming/trashing your system.

Seagate 1.5 TB external hard drive and Disk Utility

I have a Seagate 1.5 TB external hard drive. Up until recently it was working fine. I noticed that things stored on it were starting to take longer to open up. There was a relatively constant clicking noise on it, not just when Time Machine was backing up my files. I finally ran Disk Utility and it said that the volume needed to be repaired. Ever since that time the hd is not showing up on my desktop or in my finder. I used the startup disk and went into disk utility but it doesn't appear there. When I turn on the computer in regular mode and go to disk utility it is there, though. When I click "Repair Disk", though, nothing happens. Any suggestions? Do I need to just erase the disk and reformat? I was able to use a program called Data Rescue to get the most important files, but I'd rather not start from scratch.

Hi jc
Can't say exactly what's wrong or what happened. But sense you have recovered your important files your best bet is to just reset the Partition Scheme and re-Format the drive instead of trying to repair it.
1. select the drives first icon and then click the Partition tab
2. under Volume Scheme: for current select 2 Partitions +(2 in your case, 1 for TM and 1 for other files)+
3. now adjust the size of partitions by clicking on and holding the little dot between the partitions. +(you will probably want to allocate at least 1GB for time machine and the rest for misc. files)+
4. click the Option button right below that and select GUID Partition Table, then the OK button
5. then under Volume Information Name the Partitions the larger Time Machine, the smaller whatever
6. then for Format: select Mac OS Extended (Journaled) and click the Apply button.
Optionally if you have say over 500GB of data on your Internal HD it would be best to set that 1.5GB up with just 1 Partition for Time Machine only and use a second drive for misc. files.
Now that you have the External HD properly Partitioned and Formatted open the Time Machine Preference and set it up to use the Time Machine Partition.

My external hard drive accidentally switched off during Disk Utility's "erase free space" process. I restarted the external hard drive and Disk Utility, but now I get the "couldn't mount disk" error when trying to finish the erase. Please help!

My external Lacie Quadra hard drive accidentally switched off in the middle of "erase free space", and when I switched it back on Disk Utility was hanging. So I Force Quit Disk Utility and restarted it. Now when I try to erase I get
"Secure Disk Erase failed with the error: Couldn’t unmount disk."
But "erase free space" seems to work...
What can I do? I'm erasing as I'm giving the drive to someone else and I wanted to wipe it clean.
Also should I use "erase" or "erase free space" if I want to wipe the drive clean?
Please help!

Sorry I don't really understand.... there are no partitions on the drive. How do I repartition it?
And should I use "erasing free space" or "erase" for wiping clean my drive of everything? Erase seems to be faster last tiem I tried.
Thanks!

Hard drive clicking and disk utility can't repair

I have an iBook G3 that recently started making a clicking noise from the left side of the computer. At the same time it froze up and now it won't start up. I tried to start it in safe mode and it didn't work. I was able to start the OS X install disc and start the disc utility, but I get an error: Invalid Sibling Link, Volume Check Failed.
Does anyone know if there is anything else I can do to try to repair the hard drive myself? If not, how do I find someone reputable to get the data off of the drive (no I didn't back it up... ever) and install a new drive?
Thanks for any suggestions!

Hi, and welcome to Apple Discussions.
You could buy DiskWarrior and see if it can repair your hard drive. It can often repair a hard drive when Apple's own Disk Utility cannot. No guarantees that it can do it for yours, but DiskWarrior has saved my hard drive several times.
If you are able to get it up and running, be sure to back things up right away.

Hello
I am using Mac OS X 10.5 on a MacBook Pro intel 2.4 Ghz Intel Core 2 Duo, 2 GB RAM, Intel and Boot Camp / Win XP installed.
To check my user rights and repair the main HD I have installed 10.5 on my external 500 GB USB 2.0 HD. Started from it and started the disk utility trying to check and repair the Macintosh HD Partition (not win xp). I got following error messages:

Because it can not repair the errors I have started "repair disk". It says "can not unmount Macintosh HD". Even if I have started from the external disk?
So I get my install CD (Mac OS X 10.5) and started from that. I got the same errors with that disk utility.
Can someone tell me, if this are "right" errors or do I have to try more to repair this errors? My computer is running fine.
I am a bit irritated now.
Best regards

Way back in Jaguar Disk Utility would pop up dozens of "advisory" messages of no interest nor meaning to anyone except possibly some programmers. This needlessly alarmed regular users. The same thing is happening again in Leopard. The SUID messages are not meaningful nor are they errors, in effect they are announcements that some list being consulted by the utility says one thing, the actual files say something else, Disk Utility is going to assume there is a reason for actual setting and not going to change it, but you (it's kind of assuming you are the programmer) should know this. If the "Die Zugriffssteuerungsliste" is German for ACL (Access Control List) it is the same deal: an ACL was found, but no one told Disk Utility there was suppose to be one.
If the messages bother you download the whole 110MB 10.5.1 update and run it. It quiets down the output for all the SUID statements save one. Might even shut down the ACL advisories--don't know because I haven't bothered to download 110MBs of updater, I just ran the patch update.

How do I repair a damaged dmg that won't mount and Dick Utility can't repair?

Apple Care gave me wrong instructions on how to create a disc image of my internal HD then erased it. Now I have a .dmg that has the same gigs as the HD but won't mount and Disk Utility can't repair. Tried to recover files with Data Rescue 3 but that isn't going so hot. Any suggestions?
Thank you

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
I guess that it's a moot point to ask if you didn't test the dmg before you erased the drive. Do you have a Time Machine or other type of backup?
If not, it's a hard lesson to learn, but I would guess that unless you are willing to pay for expensive outside data recovery service, all is lost and you are starting over.

To turn on/off retail mode, go to settings, general, legal.
Do not open legal, just put the cursor there.
Then, on the remote, type this sequence : right - right - left - center.
The AppleTV should reboot.

How can I erase My hard drive. Disk utility only gives me the option of erase free space. I have 27in iMac with Lion and 12 gb ram.

How can I erase my hard drive? Disk utility only gives me the option to erase free space.
Thanks for any assistance.

Drive Preparation for Lion
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU to return to the main menu.
5. Select Reinstall Lion then click on the Continue button. You need an active network connection in order to download the Lion software.

Something's wrong with my hard drive, and disk utility can't repair it...
