Disk Utility Partition Error

I updated from Tiger to Leopard, and in the last 2 wks noticed I had little remaining space on my hard disk. After checking in Disk Utility, however, I found that my hard disk partition had reduced from what should be a full 160Mb, to a mere 52Mb or so, but there is NOT another partition (just a grey area for the rest of the blank space)! When I try and increase my hard drive partition a little or even to the full amount, I get an error:
"Partition failed with error:
MediaKit reports partition (map) too small"
I've tried updating to 10.5.2, OS is totally up to date, and have tried starting up from Leopard install disk and using Disk Utility on that to try and increase partition, but all with same error.
Not sure if related, but when I try fix permissions, there are a few unfixed problems regarding ACL's (?), but no other issues.

I am having the same problems on 10.5.2. I have a maxtor onetouch 500gb, I reformatted it to work with time machine, and the partition on the disk is only 382.4gb, with a lot of grey space showing up. When I try to expand the Onetouch partition or create a new partition to fill in the space, it keeps giving me
"MediaKit error: size of disk too small" or something along those lines!

Internal Hard Drive Died - Now replaced - Disk Utility Internal Error

When using the original system disk to install OSX the new hard drive isn't recognised even though I have formatted it for an intel based mac (GUID Partition, Extended Journaled etc) using my imac . When launching Disk Utility from the system disk and trying to erase/partion the drive, I get the following error message "Disk Utility Internal Error - Disk Utility has lost its connection with the Disk Management Tool...". When connected to my imac using a converter it appears on my desktop. Any help would be greatly appreciated. The macbook in question is a 2006 (white). PLEASE HELP.....

Hi - Thanks for your reply. I have tried that but it still doesn't work. I have had a look around online for the past couple of hours and I found a post that said that newer hard drives can't be recognised by an original 10.4 osx system disk. I would need to find a copy of 10.5 to install OSX on a new hard drive. I dont know if that's true because I dont have a copy of 10.5. Any thoughts would be appreciated!

Disk Utility internal error message

I am receiving an error message every time I try to repair permissions on my MB running OS X 10.4:
error:
Disk Utility Internal Error
Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and re launch Disk Utility.
Tried that several times to no avail. After quittting Disk Utility, system becomes very sluggish and Finder stops responding.
I then booted from the installation CD and ran a Hard Disk integrity check. It checked Ok. Then I tried a permission repair and got the exact same error message quoted above.
Any help?

There was a problem with this a couple of years ago involving iTunes Library Receipt files. See [Mac OS X 10.3: Repair Disk Permissions 'Disk Utility has lost its connection with the Disk Management Tool.|http://docs.info.apple.com/article.html?artnum=303132].
It seems unlikely that would surface now, but the suggested fix is worth trying. The article also mentions looking at Console log. Console is in Applications/Utilities.
Also, see this recent thread in the Panther forum:

Disk Utility: Burn error: 0x80020022 The device failed to respond...

I've been working on archiving a ton of video to DVD. I'm using Dual-Layer discs to minimize the amount of physical storage space needed for the finished project. I burned several discs in iDVD in July and regularly received errors. Then the drive suddenly stopped loading any type of media. Anything I inserted would spin briefly and then eject. Repaired permissions and followed steps outlined here and here. Took the Mac back to the store where I bought it (sadly, not an Apple Store - nearest one is 12 hrs away) where naturally it performed flawlessly for the store rep.
So I took it home and resumed burning, now saving as a disc image (ignoring iDVD's warning about the performance of DVDs burned this way) and using Disk Utility, since iDVD didn't seem to be reliable. Burned about 25 discs, error-free, in this fashion, then three days ago, got the error: "Unable to burn “Disc 19.img”. (The device failed to respond properly, unable to recover or retry.)"
Retried the same image, and it worked. Then burned two more in the same fashion with no errors. Today I got the same error again. Logs are identical for each failed burn, except for the time span between certain lines.
Price of DL media being what it is, I'd hate to keep ruining discs if there's something I can do to avoid it. I suppose it could be bad media, but it seems odd that I'd get two bum discs that close together after burning so many without issue. Checked the site and the forums, and there doesn't seem to be any answers. Does anyone have any ideas? (Other than "try a different brand of media." I've got a buttload of these discs and it's too late to return them now.) Even if it just helps determine where the issue lies. Warranty will be up soon, so if it's hardware related, I need to get it taken care of quick.

I have encountered the same problem. I have a Mac Book Pro from 2007, and it has gone through 3 DVD writers so far, all of which have ruined DVD+R DL disks. I have occasionally been able to burn one, but usually during verify, I get this error message:
Communication to the disk drive failed: 0x8002022
And disk utility fails with a "Invalid B-tree node size" error
Oddly, when I try to burn a disk near capacity (6.5Gb or more) it is more likely to fail than if I burn a smaller disk.
I've been using Memorex DVD+R DL disks, but I have used other brands in the past but they have failed, too. Out of about 50 disks so far, I have had success with about 5.

I have a 32GB thumb dr and I wanted to encrypt it. I used disk utility, Partition, apply. Then went back and tried to encrypt it and it still ask that GUID be setup on it. What must I do now, or how is the better question?

What do I do? Please help me. (Mountian Lion, Disk Utility, Partition, Boot Camp)

I was trying to upgrade my snow leopard to mountian lion on my macbook pro 13". I didn't fully understand how to do it so I googled and found out i had to make a partition with a specific format. Prior, I did a bootcamp so I can install window 7. I partitioned my macbook with window 7 and osx. When i went to disk utility i didn't have enough space so i deleted my window 7 partition. ( i think i did it unproperly hence i have the problem). When i deleted it, it gave a random partition disk, my apple partition and the empty space i deleted for my window 7. I basically gave up on my mountian lion installation and restarted my computer. When my computer boots up it comes up with "Non-System disk" "Press any key to reboot".
What i tried was to stick in the mac ox cd in, and the application cd. Both doesn't work. Im trying to find where my window 7 cd is to see if i can restore the partition i deleted. I thats not the solution please help me
UPDATE: Also i was thinking about buying the Macbook Pro 15". With the current condition i have on my macbook pro 13" am i able to recycle it and get some store credit for it?

Once you back into OS X, reboot holding the command option r keys down, or command r keys and use that Disk Utility to repair your drive or MacintoshHD partition.
Then reboot normally and use that Disk Utiltiy to grab the little corner resizer of your MacintoshHD partition and drag it over the gray space at the bottom to reclaim the deleted Windows BootCamp partition.
If you want to try Mountain Lion, I suggest you do so on a extenral powered drive.
1: Format a external powered drive in Disk Utility Partition 1, Option: GUID Format OS X Extended Journaled and give it name like Mountain Lion (formatting a drive erases all data on it)
2: Download to Snow Leopard, Carbon Copy Cloner and use it's default settings to clone your MacintoshHD partition to the external drive.
3: Reboot the machine holding the option/alt key held down, boot from the clone.
4: Use that clone of Snow Leopard to upgrade to Mountain Lion via AppStore.
5: If and when your ready, you can boot from the 10.8 clone and reverse clone or clone Snow Leopard to another drive or whatever you need.

Disk utility gives "Error: Partition map repair failed while adjusting structures to fit current whole disk size"

I am getting the following error when running Disk Utility (under ML) on an exteral USB hard drive:
Error: Partition map repair failed while adjusting structures to fit current whole disk size.
I get thsi when I ask Disk Utility to "Repair Disk" at the top level of the disk hierarchy (i.e. not on one of the partitions within the disk but on the disk itself). I was not getting this error with Lion on the same disk before I upgraded from Lion to ML.
It seems like a bug in ML. I found websites where they suggest that you just run Lion's Disk Utility and it will show the disk to be fine.
Any thoughts?

So, I finally seemed to have resolved things with the Seagate 4TB Firewire external drive. If you Google about, you will find a thread on Seagate's own support forum that describes how to disable the sleep function on the drive. You CANNOT ALLOW THE DRIVE TO SLEEP WHILE CONNECTED TO YOUR MAC.
After a lot of reading, here's what I think is happening: the drive goes to sleep, after some period of inactivity, and when you shutdown your Mac, OS X tries to write something to the drive as part of the dismount / disconnect / shutdown process. That fails in some manner, leaving the drive 'corrupted' at the filesystem or partition level.
Then, on the next boot-up, Mountain Lion tells you that it cannot repair the drive and it mounts as read only. Your only fix at that point is to re-partition / re-format and start over (which is big fun with 3TB of data to copy back on to the drive).
If you prevent the drive from sleeping, whenever it's connected to the MacBook, then the above process doesn't occur and voila, the drive just works. So far, I haven't had any problems with about a week of starting / shutting down my MacBook connected to the offending drive (translation: I was going to return the drive, but the problem is clearly with Mac OS X Mountain Lion).

Disk Utility - get errors and disk utility can not repair, even start ext.

Hello

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.

Disk Utility - Partition map needs repair because a data partition needs loader space.

I just finished setting up both my OSX and Windows installs from scratch after fitting an SSD, which in-turn was right before my logic board died and Apple replaced it, now it looks like I have some sort of hard drive issue brewing.
This was my plan for the SSD, and how it currently displays in Disk Utility although that wasn't the case earlier:
And in Terminal:
My intention was to have two boot partitions for each OS, 'Macintosh HD' and 'Win 7 Pro' and a third shared data partition 'Projects' on the SSD, which I made in Drive Genius after installing Boot Camp. I don't want Macintosh HD accessible from Windows because I'll be using Paragon HFS+ or MacDrive to give write access and don't want OSs stomping on other OSs turf, hence needing three partitions. Everything looked fine until I just checked Disk Management under windows and realised it couldn't see the Projects volume. Even though it's fine in OS X, it was just marked black/unallocated space.
So I booted back into OSX, all my files look fine so I ran Disk Utility and the Partition tab looked really odd - unfortunately I didn't get a screenshot. All volumes reported their size correctly but visually, Macintosh HD took up most of the drive. I could see 'Windows 7 Pro' under this, but the Partition Layout section had a scrollbar, which if I scrolled down showed 'Projects' squished into a tiny gap at the bottom. I ran a Verify, which reported no problems, and at some time since the Partition Layout has reverted to how it should look (as in the screenshot above), with 'Projects' book-ended by "Macintosh HD' and 'Windows 7 Pro'.
Now when I run a Verify on Macintosh HD or Projects volumes, it says there's no problem, but if I run one on the drive, I get this message:
Volume Macintosh HD on disk0s2 has 0 bytes of trailing loader space and it needs 134217728 bytes
Problems were found with the partition map which might prevent booting
Error: Partition map needs repair because a data partition needs loader space.
I've only managed to find one other mention of this error here, but the fix is not relevant to me because I don't have Sophos installed. I've tried Single User/Safe Mode but it just boots into normal mode, so I can't do a fsck -fy.
** /dev/rdisk0s2 (NO WRITE)
Can't open /dev/rdisk0s2: Permission denied
That value in bytes is exactly 128mb, so I suspect the problem lies with one of the invisible partitions that show up in iPartition and Disk Management under Windows, but not in Disk Utility. I have backups and I suspect the root of the problem is partitioning in iPartition after installing Boot Camp, but I've never had issues with this approach in the past so I'm wary of just giving up and reinstalling Windows again will be massive hassle because I no longer have a SuperDrive and last time it refused to install from USB.
Anyone have any idea what's going on? It seems like the sort of issue Disk Utility should just handle, at least in Recovery mode, but it's not playing ball. It also doesn't seem like a massive problem since my files all look fine and performance is OK, so I'm reluctant to do anything major.
I'll update with a shot of the drive in Disk Management from Windows in a few minutes, in case that sheds light on anything. Thanks!

Similar issue here. I manually partitioned my hard disk for triple boot (using Gparted on Linux), then everything was just fine until I ran bootcamp, to do something as simple as create a boot USB.
I get the same error as a result and have to work my way into booting, by resorting first to a Linux live USB, then restarting from the live USB, to finally reach my rEFInd boot manager, or whichever boot manager should be initialized at startup.
I suppose that the cause in my case is that some operation "scratched" the protective MBR. See this:
http://www.mactech.com/articles/mactech/Vol.23/23.03/APMtoGPT/index.html
I am hoping to fix it using an external Yosemite installation media: see this guide -
http://www.macworld.com/article/2367748/how-to-make-a-bootable-os-x-10-10-yosemi te-install-drive.html
And as a last resort to reinstall.
I'll admit I am negatively surprised. I need this computer for professional reasons, and for the sake of "preserving the integrity of OSX", measures defined by Apple instead tend to make partitions far easier to damage. And this problem seems to affect a number of users.
As for what I have to go through to fix it: a 5GB download, during which I have to register my credit card to the Apple Store. "Pay first, get your free software next."
IF Disk Utility can fix it, from the external media, then fair enough. The hassle is unpleasant but it files as "a choice".
Otherwise you can file it safely under software design calamity.

Disk Utility gives error and does not rebuild mirrored RAID

After having a HDD fail on a mirrored RAID I replaced the HDD and attempted to rebuild. Disk Utility reports via Console that it can not find an Apple Boot partition to check size and then fails to repair the RAID. Details follow.

I configured this RAID scheme (two two drive mirrors striped together) according to this kbase document: http://docs.info.apple.com/article.html?artnum=304377
As shown in the above "diskutil checkRAID" output I have a failed HDD. So I replaced the HDD with another 160GB cold spare. I added the new drive to the mirror "Mirror_1" also known as disk5 and hit rebuild. Received the normal message that all data on the new drive I was adding would be erased.
I then receive the following error immediately in the Console Log:
Rebuilding RAID "Mirror_1"
2006-12-15 23:50:24.741 DiskManagementTool [375] WARNING: Could not find Apple Boot partition to check it's size, skipping disk5s-1s.
Rebuilding RAID slice "disk4s3"
Just to stem some confusion, the device ID disk4s3 has been used by the system for both the old failed HDD and the new replacement HDD.
The result of this attempted rebuild is I end up with all the data from Mirror_1 on the new HDD but the new HDD is not successfully added to the RAID, therefore Mirror_1 is still degraded and my problem not resolved.
I ran the appropriate rebuild cmd from both the GUI Disk Utility as described and from the CLI "diskutil repairMirror disk5 disk4s3" but no joy.
Any help would be greatly appreciated. This volume houses a large amount of important data including user home directories so while some offline time may be required data loss would not be very acceptable.
Thanks in advance and I will be happy to provide more information as necessary.

I guess doing it in Terminal would fail too:

Leopard and Norton Auto protect - Disk Utility Reports error on disk verify

Hi There,
Leopard 10.5.1, Norton Antivirus 10.1.1(2) with "auto protect on" has some incompatibility issue. Running "Verify Disk" from "Disk Utility" stops producing some error message in red colored text. Repair disk option is not available. However, verify disk on starting up with Leopard installation DVD shows no error. Verify Disk when starting up from Leopard 10.5.1 HD and norton auto protect disabled reports no error. So, looks like some compatibility issue.

I have been going crazy with this for the past fortnight: with theh rapiudity of the onset becoming far too frequent.
Norton AntiVirus AutoProtect could not continue. Please run LiveUpdate or reinstall AntiVirus and ReStart (Code:9)
This is what I get! I turn it back on, and zap. I reinstasll, and, zap.
I chatted with Symantic, they gave me a link for an update to the Stuffit engine, apparently may be a cause.
Well, that was No Use. Zap, you guessed it!
FYI:
I run iMacG5 17" 160HD, partitioned,Leopard on one partition, Tiger on the other. works well.
Oh, and, the Auto Protect doesn't zap in Tiger!
any ideas? I can share logs of Crash.
thanks, George.

Apply Disk Utility Partition Changes not Applying

Hey Folks
I've a 2013 iMac with a 3TB Fusion Drive - Currently the HDD is split 2.48 TB as the primary HD - and 521 GB as FreeSpace.
What I want to do is format this 521 GB section for Windows Bootcamp - The Bootcamp Utility created this split in the first place; but after sitting for 5 hrs it appeared to feeze mid-process and after checking for advice online; I reluctantly force-quit the utility. Next I attempted formatting this HD section in Disk Utlity as MS-DOS (FAT) but when I choose Apply - and click Partition - absolutely nothing happens - and no changes take place.
When I re-open Bootcamp Utility - it's seemingly unaware of this 521GB of Free-space and only sees the primary Partition; which I do not want to further split up - remember it's Bootcamp stalling in the middle of the partition process that caused this mess in the first place.
I've also tried booting form the Windows 7 Disk to reformat and Partition this Free-space - but the installer just spits back the message that the partition is GPT and Windows 7 requires NTFS. So next - I bought and installed Camptune X - which now adds the NT file-system formats directly into Disk Utility but since I cannot 'Apply' these changes - it makes no difference whatsoever.
To troubleshoot - I've already repaired my HD permissions, and repaired the drives, booted into recovery mode - done the same steps - but am now at a totally loss what else I can do to successfully create a Windows Partition - if Disk Utility simply won't Apply any of the changes I select.
Any suggestions or advice yourselves could give me would be hugely appreciated.

Hey Folks
Still no luck - I've now tried using iPartition to add a new Windows formatted Partition in the area that is currently designated 'Free Space' and I get this error message.
"iPartition was unable to get write access to the device .... This may mean the device is write protected, that you do not have permission to access it, or that it is in use by something else. "
Does this mean I can unlock the write access through a command in the terminal and return to Disk Utility or indeed iPartition to add the Windows Partition I need?
Some advice would be hugely appreciated.

Disk Utility Reports Errors

I have just erased my HD and reinstalled all my programs. Things were running fine for about a week. When I went to run a very disk... this is the message I received.
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.
Reserved fields in the catalog record have incorrect data
Checking volume bitmap.
Checking volume information.
me %@ needs to be repaired.",1)
Macintosh HD
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
I then used the Start Up DVD to run Disk Utility and it said 1 volume repaired, 1 volume can't be repaired. But all I did was run in on my HD... my 2 other External drives checked out OK...
So... what exactly is the problem... is my HD faulty or is this a problem arising from installing other programs like Limewire and Windows Media Player. I JUST wiped my system clean a week ago and need to figure out what is going on... any ideas...
Thanks,

You're welcome.
The Format is Extended and Journaled...but what exactly does this mean???
If the hard drive format is Extended with Journaling enabled (which is done at the factory and requires reformatting the hard drive to change it), performing an Erase & Install will not change the hard drive format unless you select a different format when doing so.
Mac OS Extended format is a hard disk format that increases the number of allocation blocks on the disk. Mac OS Extended format optimizes the storage capacity of large hard disks by decreasing the minimum size of a single file.
Check this link for information about file system journaling.
http://docs.info.apple.com/article.html?artnum=107249
This link provided instructions for checking a hard drive for bad blocks.
http://docs.info.apple.com/article.html?artnum=24764
You should also check the Smart Status for the drive.

No... It is only 80G... should it be partitioned? Again what
does this really do???
No the hard drive should not be partitioned unless you want or need it partitioned. Some prefer partitioning their hard drive for various reasons. As an example, you can partition the hard drive into two partitions and install 10.3 on one partition or volume and 10.4 on the other providing the option to boot the computer from either the 10.3 or 10.4 partition or volume. Some create and use a separate partition or volume to store all data keeping OS X and all applications on the boot volume partition.
Should I erase the Limewire program and any files I downloaded???
I thought Macs were impervious to viruses... so I thought it would
be alright...
There is no computer operating system that is completely impervious to viruses and malware but OS X is about as close as it gets - especially when compared to the insecurity associated with Windows. Although there are no viruses that currently affect or infect OS X, there are some Trojans and malware that do. I could email you an AppleScript programmed to erase all data in your Home folder/directory. You would be prompted for your admin password before doing so but if you trusted me and/or what I sent you and you opened and ran such a malicious script, bad things can happen.
Not long ago, there was a download available via the P2P network with Limewire that indicated or was shown as a free install of Microsoft Office for OS X. The size of this download was not very large - not anywhere near the size required to include Office X but some unsuspecting folks downloaded and ran this malware which completely erased their entire Home folder/directory. No antivirus software would be any help with such a malicious script since not a virus.
There must be some trust involved when downloading software or files which is the reason we should do so from known and trusted sources only. If you choose to continue using Limewire (which most use for downloading music for free which is stealing from musicians and record labels in effect), if you are ever prompted to provide your admin password for any reason out of the blue when opening a file downloaded with Limewire, you should always decline.
After I did the reinstall... everything looked good for about a week
(no errors when I ran Verify disk) did I not really do a complete erase
and install? Did I go wrong during the install process???
I don't believe you did anything wrong during the install process. If you performed an Erase & Install using your Panther install package and then you upgraded to Tiger using the Tiger retail install package, are you checking the hard drive via Disk Utility when booted from the Tiger retail install package?
If so and there is a hard drive directory problem that Disk First Aid repair cannot successfully repair, your options are using a more substantial disk repair utility such as Disk Warrior (which is highly regarded for OS X but comes with no guarantee) or checking the hard drive S.M.A.R.T. status first and if OK, checking the hard drive for bad blocks per the links I previously provided and then re-install Panther and all included software included with the install package that shipped with your Mac. Afterwards, check the hard drive for any directory problems again via Disk Utility when booted from the Tiger retail install package before installing Tiger.

Boot Camp and Disk Utility giving Error for my Hard Drive Volume

When trying to partition my Hard Drive with Boot Camp, I get an error message after a while saying that it can't be partitioned because there is an error in the volume and that I should check it in Disk Utility. After running Verify Disk, it had told me that the file count was wrong and that I should repair my Disk. I have leopard installed, but only had access to a Tiger Install Disc, so after booting to that and apparently repairing successfully, I booted back onto my Hard Drive and ran Disk Utility's Verify Disk again. Now it said that my Volume Header needs minor repair. I still get the same message in Boot Camp. Running Verify and Repair Disk from the Tiger Install Disc tells me that everything is alright and the Hard Drive doesn' need repairing. I read on an Apple article that verifying a disk that's booted can produce inaccurate results, and that it shouldn't be worried about, but I can't install Windows because of this! What should I do?

Hi,
you have to boot from the Leopard OSX DVD in order to repair the Leopard OSX volume on your harddisk.
Using Disk Utility from an OSX version that is prior to the one you want to repair can indeed cause more errors than before.
So, search for the Leopard DVD.

Repeated Disk Utility & fsck errors - what to do next?

After nearly a year of flawless operation (yes, my warranty will soon expire), my iMac has suddenly started to misbehave. Disk Utility has reported finding errors which it is unable to repair. I've run fsck_hfs in single-user mode a couple of times, and after each reboot it again finds errors. Then I bought DiskWarrior and it repaired my drive. All was well for nearly a day, and now I'm back to the same situation. So, what to do now?
Should I reinstall the OS and just run it bare without any additional apps for a while, to see if I get more errors? (I've made a SuperDuper! bootable backup which I should be able to reboot from if needed). Or are these repeated errors to be more likely the sign of permanent problems with my hard disc, and I should go to the local Apple store without wasting any more time?
Fortunately I have a Powerbook to hold me over as a spare machine if I do have to give up my iMac.
All suggestions welcome.
Thanks
S

Since you have a backup I'd suggest you wipe the drive and reinstall. Do this:
Extended Hard Drive Preparation
1. 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 or Leopard.)
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. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Upon completion quit DU and return to the installer. Now complete the reinstallation of OS X.
