Hard Drive Issue? Disk Utility issue?

Every once in a while i run disk utility to see if my disk is running properly. I ran permissions and got all of this in the log window. I backed up my drive and re-installed MacOS X and re-ran permissions and got the same log below. I then ran DiskWarrior and rebuilt my directory, then re-ran permissions again, again getting the same log below. What does all of this mean, and what can i do to fix this?

What does all of this mean,
Nothing to worry about.
and what can i do to fix this?
Nothing - Apple will need to clean this up, which they will probably do with some future update. In the meantime, there's no need to worry about any of the above.

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.

Problem partitioning external hard drive with Disk Utility

I'm trying to create a new partition in disk utility in an external hard drive using disk utility and every time I click Apply it says that "Disk Utility has lost its connection with the Disk Management Tool and can't continue. Quit and relaunch Disk Utility". It is a 3TB hard disk and I already created the first partition of 2 TB, and when I click the + symbol to add a 1 TB partition and click Apply is when the error shows up. I have restart the mac, unplugged the hard disk but the error still shows up. Anyone has any idea??? Thanks for your help in advance
David

I solved this issue. I was able to create the partition with the format MS-DOS and then I erased it to the Mac OS Extended (Journaled) format.
Now it is working OK. Hope this help someone

Unable to verify or repair my external hard drive with disk utility, reason being ...

Hello there,
I have been facing this problem: After I started getting an error 50 error while trying to view in Quicktime player a movie which I had exported from FCPX today, I found that I was not even able to trash the movie [this was a test movie used for export and I had no need for the same]. A little while later when I opened FCPX, I found this message pop up:
Got a little worried and then tried to verify and repair my hard drives using disk utility, but I could neither verify nor repair the disk. What should I do now?

Hello Klaus,
I think I have been able to overcome the problem/s.
I have been using my Seagate 2 TB drive [2 USB] with a FW adapter and was using FW connectivity for the past several months without any problems. About 2 months ago I added a 2 TB Lacie, FW, to my workflow and this EHD was daisychained to the Seagate. Had been facing no problem with this arrangement until today.
Now let me try to tell you what I had done:
I ejected the Seagate drive with the intention of reconnecting it again. But, no, when I tried to reconnect, this message came up:
After several attempts, I did this, connected the Lacie by FW to the FW port on the Mac and connected the Seagate by 2 USB. Was I glad to see my Seagate HD icons shining in all their glory on my desktop! I utilised the services of disk utility and was informed that these prodigal sons were absolutely fine.
I also tried to do this: empty the trash. Was I happy to hear the sound of files being cast out?
Well, well, at least I will be able to get some peaceful sleep now! I have not yet opened FCPX, but I trust it will also be reading the Seagate HD once again.
Good night and thanks for being helpful.

I have a Macbook Pro that was slowing down. The HD was nearly full as I do a video work. I removed over 400gb of photos and video and it made no difference. I ran disk inventory x and that says that there is only 60gb on the hard drive but disk utility says there is still 430gb on the HD. How do I remove what DU says is still there.
Thanks

You may notice a difference in available space statistics between Disk Utility, Finder, and Get Info inspectors. This is expected and can be safely ignored. The Finder displays the available space on the disk without accounting for the local snapshots, because local snapshots will surrender their disk space if needed.

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.

Cannot find the Hard Drive on Disk Utility

I am using an iMac (mid 2010) the factory Operating System was Mac OS X 10.6.4 and updated to Mac OS X 10.9.1.
Following a "Flashinhg Question Mark" iMac was unable to boot.
Then installed OS X on an external HD and boot the iMac. http://support.apple.com/kb/ht5911
iMac is working with the external Mac OS but in the "System Preferenses>Startup Disk do not show the internal Hard Drive.
Following this issue the iMac fan is working fast and noisy.
I tried
1. SMC reset
2. PRAM reset
3. Safe Boot
4. Boot with the external USB Mac OS X
nothing helped me.
Thanks in advance for any guide.

Cornelius,
I was in the process of running Disk Utility last night to repair permissions when it gave me a message that it could not connect to Disk Management Unit (I think that was the name) and suddenly quit. I tried again, and the same thing happened. Then, the computer froze with the spinning rainbow again, and I had to do a hard shutdown. When I tried to restart, I got a gray screen. I tried squeezing the left corner again, and after a couple of attempts was able to boot the computer. However, it froze again and had to be shutdown. This cycle happened a few more times before I decided to give it a break.
This morning, my husband turned it on to see what it would do, and it started up normally. However, we restarted it so that we could repair the disk, and it took several tries before it could see the HDD. I tried "repair," and it seemed to work for about a minute before giving me the same error message: "The underlying task reported failure."
My husband and I believe we have some sort of logic board problem, specifically the ATA controller. What is your opinion, and what would you suggest next?
Thank you for your help so far!

Can't use or fix external hard drive in Disk Utility or Terminal

I have a 1TB Toshiba external USB drive that I was using for Time Machine and other storage. A couple of weeks ago I accidentally unplugged it when it was in the "Preparing Backup" stage of Time Machine.
Since then, when I plug it in, the light on the drive goes on and it spins, but it doesn't show up on the desktop or according to Time Machine. It DOES show up in Disk Utility with the correct partition showing. However, I have tried to erase and partition the drive and I keep getting the message that Disk Utility can not unmount the drive. I tried using Terminal to force unmount the drive and it also failed.
When I run the repair on the physical drive in Disk Utility, it says everything is fine but when I run it on the partition within the drive, I get the message, "Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
No using the drive, no repairing, no unmounting, no partitioning, nothing works.
Any suggestions to simply make it usable. I don't care about the data on it, I just want to be able to clean it and start again OR access the data.
Thanks!

Boot into Recovery mode, launch Disk Utility, and try to partition the drive. If you can't, it's not working (or perhaps the cable is damaged.)

Trying to install/format an INTERNAL hard drive using Disk Utility gives me "Error: -69760: Unable to write to the last block of the device". Is that a hardware problem and what could be done about it?

*** PLEASE NOTE*** - This is a query about an INTERNAL HDD not an external one. Thanks.
My Mac is a late 2009 model and the current hard drive recently failed. So I bought a new one, exactly the same, albeit 750gb instead of 500gb. The HDD is a Seagate Momentus 7200. Before the my current drive failed I made a time machine back up to an external USB HDD. I've inserted the HDD into the bottom of my Mac, plugged in the USB and started my machine pressing the 'Option' ([ALT]) key. I go into Disk Utility to try and format the new HDD by creating a new partition but I keep getting the messages,
"Error: -69760: Unable to write to the last block of the device"
or
"POSIX: could not allocate memory"
This is actaully the third HDD I've tried. The first was another Seagate Momentus 7200 500gb, but this time it was a newer model (model number ended in 423AS instead of 420AS - the new one I am trying ends with 420AS, which is the same as the current HDD). I then tried a Western Digital drive but that one didn't even show up in DU. Forums and tech support are suggesting it's faults with the HDDs but surely not three in a row?
Could this be an issue with another part of my Mac?
Is there anything else I can do to format the HDD, have I missed a crucial step?

Did you ever get a resolution to this issue?
I am having that exact error with a new 512GB SSD from Crucial, in a 15" MBP mid-2010.
I really wonder now if the stupid SATA cable could be bad - causing the initial SSD fail. I am replacing it with the EXACT same drive, and getting that "last block" error when i partition in the GUI or from command-line.
thanks!

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.

Repairing internal hard drive from disk utility

Hey folks,
I need to do a repair of my internal hard drive on my PB. I understand that in order to do this, you need to boot from another disk. I cloned my hard drive using CCC to an external firewire hard drive so I can boot from the external.
So I shut down and rebooted while holding the option key but the external hard drive did not appear as a choice for which to boot. So I booted with the internal and went to the Start Up Disk icon in System Preferences. There, the external appeared so I told it to restart using it.
After restart I went to the Disk Utility to repair the internal but when I did, the "repair" button would not illuminate. I'm pretty sure I'm running off the external because when I use spotlight, it searches the external and not the internal.
Any ideas?
(I'm trying to boot off an external because I cannot find my OS X disc referenced here: http://discussions.apple.com/thread.jspa?messageID=6642196#6642196)

If the "repair" button does is not selectable, maybe you indeed restarted using the same INTERNAL drive by mistake? Also, it could be that your INTERNAL hard drive is beyond repair, as which happened to my PowerMac's a few weeks ago and I--which I just mentioned on another forum--had to buy Data Rescue II to salvage my data because the only solution was to reformat the drive. It was beyond repair.
I don't know if this helps, but which did you select? The disk itself? (first in the hierarchy) or the volume (second in the hierarchy... list). Sometimes that matters. But I couldn't tell you since I can't see your screen and don't know your exact issue unless I saw it or was able to test it out.
The other thing could be, are you selecting the EXTERNAL by mistake on the list of drives on the left? You can't repair the disk/volume that you are booted up from, why you would need your software discs / restore discs to do that. But since you are doing it the "workaround" way, which should work, that is my guess.
Message was edited by: Pismo 900
Just a suggestion, why not just erase and reformat the damaged drive, and then once that's over, do a "Restore" from Disk Utility, choosing your external as the SOURCE and the internal that's been reformatted, as the DESTINATION.

HT1553 How to backup an image of internal hard drive on external hard drive with disk utility

I've followed the instructions under the paragraphph 'Instructions for backing up to an external hard disk via Disk Utility
in this article: http://support.apple.com/kb/ht1553. My external hard drive is plugged in. I mount my install DVD of Leopard and restart. Press C to boot on the DVD, select the language and go to Utilities -> Disk utility.
However I'm blocked in step 9 when I have to choose the destination. I don't have the option to select my hard drive to back up the image. I only have 2 options: root or Applications to save the image. Nevertheless, I can see my external hard on the left.
- Could it be because the internal hard drive is encrypted?
- Could it be because the external hard drive is encrypted?
Note also that the button 'Verify disk' is greyed out.
Any clue?

I always advise Mac users to never:
encrypt a disk
set a firmware password
In my experience they cause more loss of data than they are worth.
On Leopard I always use the latest free Carbon Copy Cloner to backup and clone disks - it is so simple to clone to either a disk or disk image. The free version may not be compatible with later OSs.

10.4.10 will show external hard drive in Disk Utility (in turn, mount)

Here's the problem in a nutshell. When I'm running 10.4.10 my Seagate Barracuda 7200.10 (installed in an external enclosure) will not show up in Disk Utility (in turn also unable to mount). My DVD-RW burner will work, the enclosure is fine. When I boot off of the Mac OS X Install CD and run Disk Utility the drive and its partitions display. I did an archive and install and they were back in Mac OS X (10.4.7). - Rather than using Software Update, I decided to download the 10.4.10 Combo update manually and install (with the drive ejected and unplugged of course). Same issue once booting in Mac OS X 10.4.10...
Before I do an archive and install again, and revert to 10.4.9 indefinitely, is there anything I can try. I did googling, deleted some preference/cache files with no success.

This bug popped up after 10.4.9 was released and many folks (myself included) have experienced the same problem - after the install external hard drives, both FireWire and USB, are no longer accessible or visible.
In fact, I'm searching the discussion boards now to see if the 10.4.10 update fixed this. Apparently it has not.
Here are some other threads about this and 10.4.9 that might be of use to you:
http://discussions.apple.com/thread.jspa?threadID=897541
http://discussions.apple.com/thread.jspa?threadID=892387
I finally reverted to 10.4.8, which perfectly recognizes my external drives, and will not update until I know this bug has been fixed. As far as I know, reverting is unfortunately the only way to fix this issue.:(

External hard drive error / disk utility not repairing

I am having problems with a particular external hard drive. Device is a Transcend StoreJet 25M (640GB) currently formatted in Mac OS Extended (Journaled). It was previously formatted in FAT32, exFat, and also Mac OS Extended (Journaled). It started giving me problems when I used it to store all my music on it. My iTunes library and music files were all stored on it, and at one point iTunes started acting funny - it would play a song for a few seconds, pause, play for a further few seconds, pause again, and so forth. I decided to stop using it and when I shifted the iTunes library to the Mac internal hard drive and the music file into another external hard drive, iTunes worked fine. So I figured it must be a problem with the external hard drive itself.
I recently reformatted it to Mac OS Extended (Journaled) and transfered some data on to it (include a back up of the music folder). I noticed that Spotlight keeps trying to index the drive but never actually managed. Times indicated for indexing runs into days. The hard drive tends to be slow to load files expecially when there are multiple folders and tiers, and is generally unreliable. It occasionally unmounts, or when I try to unmount it I get an error saying it cannot unmount because it is being used (but no indication as to which app is using it even if all apps are closed except for Finder).
I tried repairing it using disk utility. The attached image shows the results. It seems that it can't be repaired by disk utility. At this point, and after much deliberation, I would have to questions:
1. Should I just smash the thing on the floor?
2. Is there another application I could try and repair it with?
3. Even though I have reformatted it several times, it keeps giving me the same problem. When I do a disk verification of the hard rive itself it all seems fine, however when I do a disk verification or repair of the volume I get the error shown in the image. Is this a problem being caused during formatting?
Any help would be much appreciated.

Oh, I forgot to attach image....

Unable to erase external hard drive with Disk Utility

Macbook Pro (mid 2010) running 10.9
Hello
Recently, my Seagate FreeAgent GoFlex 1 TB external hard drive has not been showing up on my desktop or in finder. The light is on when connected, and in the Disk Utility it appears.
1. It was naturally created with a partition on it (all of the 1TB allocated to it) and it appears in the Disk Utility as well; however, it is grayed out.
2. I clicked the actual drive in DU and it was verified as being ok. I clicked on the partition next to verify and it said "Error disk needs repaired"
3. So I clicked repair, "Disk Utility cannot repair the disk..restore as many as your backed-up files...etc."
4. No problem (the data on the hard drive is used for my Time Machine back ups and my current internal hard drive is working fine with all the data intact)
5. Ok, so I click the erase tab on the entire external hard drive...erase..."Disk cannot be unmounted"
6. Ok, I try to erase the invidual partition..."Could not open disk"
It seems every time I try to erase this drive completely im hitting blocks. I even tried this method from the OS X Recovery menu (Command+R on startup). I would greatly appreciate any help to just get this whole thing external hard drive erased and start anew. How else would I go about this?
(pictures for reference)
Thank you all

If this is your only backup device, you need to start a new backup on another drive immediately. Don't erase (or try to erase) your only backup.
After you have the other backup, boot into Recovery and try again to erase the volume. You will have to unlock it before you can do anything with it, because it's encrypted.
If you still can't erase it, the drive has failed.

Snow Leopard Installer does not recognize Hard drive in disk utility.

I first at the suggestion of apple technicians because of other problems erased and partitioned hard drive. Now when I go to reinstall Snow Leopard it does not recognize the Macintosh Hard Drive, not even in disk utility. Any help will be greatly appreciate.

To make sure we understand everything correctly, you are saying that when you start up from the Snow Leopard DVD & run its copy of Disk Utility from the Utilities menu, it shows only the DVD installer disc itself in the list on the left of Disk Utility's window? There is nothing else there?
Also, what are you booted from when you try to make an image of the installer DVD, the DVD itself or something else? Are you using Disk Utility or something else to make the image?
This seems very weird for sure. If you were running from some hard disk copy of the OS, I would suspect that its copy of Disk Utility or some OS support file was corrupted, but if you are doing this from the DVD that is extremely unlikely unless the DVD itself is physically damaged.
Apart from that, pretty much the only thing left is a damaged hard drive or other hardware failure in your Mac.

Hard Drive Issue? Disk Utility issue?
