Disk Utility Partition? Not there.

I have an external disk I wanted to partition. Opened DU but no partition function visible. Read the Help files. It says to select the volume in the list and the click "partition". Not much help since I can't find that choice anywhere. Just not available in this version?
Thanks,
Richard

Well as an update, I tried to change partition size but could not. I realize this is likely a different problem but will post just in case. I have a OWC Mercury Elite external drive with 3 partitions. In Disk U. I could see the partitions but on trying to resize one I get this error:
Partition failed with error:
Filesystem resize support required, such as HFS+ with journaling enabled.
It appears to me that it is HFS+ and journaled already so puzzling to me. Maybe just because it is an OWC drive?

Help ,Disk utility does not allow me to partition my internal HD

hello , i want to partition my internal hard drive but for some reason disk utility does not allow me to , when i click on the partition window everything is greyed out, i read on other thread that file vault might be the problem but is already off , i can t figure out what the issue is any ideas ??? here is a screenshot.

Not if you want to be able to restore the Boot Camp partition using Boot Camp Assistant. There are alternative boot loaders you can use to add Windows and Linux to an OS X drive. You would first need to restore your drive by deleting the Boot Camp partition you now have. Then take a look at The rEFInd Boot Manager: Getting rEFInd - Roderick W. Smith.

Disk utility does not allow to restore Macintosh HD after I deleted a small size (1GB) partition

Hi, when I tried to create a new 1GB partition (on my Mac mini 2011, using Mac OS X 10.7.3) and then to delete it I could not restore (increase) Macintosh HD size using Disk utility (diskutil list shows the same value for Macitosh HD (498,17GB) partition before and after I deleted a new created 1GB partition).
Please help, how I can restore the original size of Macintosh HD when Disk utility does not allow to restore Macintosh HD after I deleted a small size (1GB) partition?
Thank you.

The bottom right corner dragging does not help in my case, because it shows that Macintosh HD partition size is maximal, but its real size did not change after I removed 1GB partition.
Maybe any other idea can help me, for example some built-in tool like diskutil which allows to view and manage unused partitions in terminal?
Thank you.

Disk utility 12 not compatible with Mavericks

I upgraded my late 2008 Mac Book Pro to Mavericks several months ago and just tried to open Disk Utility and get a message that the version I have is not compatible with Mavericks. Mine is Disk Utility 12, is there an upgrade available? I looked on the Apple site and couldn't find one. Thanks!

Well, I'm not on my Mavericks machine at the moment, but my Mountain Lion machine has Disk Utility 13, so Mav must have at least that or higher.
Since Disk Utility is not a stand alone application, but an integral part of the OS, I'd suggest you use your recovery partition - hit Command + R keys during restart/boot up and choose to reinstall the OS. That should bring everything up to date.

Disk Utility will not verify disk because, "The underlying task reported failure on exit." Now what?

Disk utility will not verify disk because, " The underlying task reported failure on exit." The "repair disk" button does not light up. The report says that repairs need to be made to the hard drive. I have already checked permissions. What do I do next to get the repair process started? Also, I cannot find a defragmenting drive option in Disk Utility. Doesn't it exist?

You need to boot from the install DVD (or a clone of your internal) to run Repair Disk. Repair Disk will be grayed out, dimmed, because you can't repair from the same volume you are booted from.
EDIT: No, you do not yet need to use Disk Warrior or Tech Tool or do any reformatting. These steps might become necessary only if Repair Disk fails.
Unless you have very large video files, for example, there is no need to run any defragmenting utility. OS X does it all by itself on the fly.
Try Disk Utility
Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Mac OS X volume.
Click Repair. Disk Utility checks and repairs the disk.
If you don't have the install DVD, try a Safe Boot. Hold the Shift key down at startup and give it much more time to boot than usual. It's trying to repair the drive directory.

Drive visible in Disk Utility but not Finder. Why?

I have a PowerMac G4 (mirrored drive doors) with 4 hard drives installed. 3 of the drives are set-up in a striped RAID array and the other one is my boot drive with two partitions. One one partition, I have OS X 10.3 and I can see the RAID drive fine. On the other partition, I fresh installed 10.4 but the drive does not appear on the desktop. Strangly, I can see the drive in Disk Utility and it shows me the mount point. I can even unmount and remount it but it still does not show up in the Finder. I had 10.4 server installed prior to the fresh 10.4 (not server) install and that showed it fine. I tried to see the drive in Terminal but also does not appear. Why does my drive appear in Disk Utility but not the Finder?

BDAqua wrote:
Yes, it needs the path to the drive...
:-/ Yes, I got the command in completely with the path to the drive like it states in the other post. I have no idea why it didn't recognize the command as I'm not as familiar with UNIX/Linux commands as I'd like to be.
Anyways... I found the cause of the problem (incase it happens to anyone else). Here's what happened:
The ownership on the root of my RAID volume was set to be read/write for me (under my proper username) and no access for anyone else including Admin. When I installed a fresh OS, the default user was Admin (who had no access under the previous OS). If I would've taken the time to set-up my proper account (with the same owner name as my previous OS) then it would've been visible again but since I didn't see it under the default Admin account, I stopped there to troubleshoot. Another way to make it visible was just to change the access privileges from my previous OS to be read/write for other users (or at least Admin). I would think that checking the box for "Ignore ownership on this volume" would've remedied that but for whatever reason, it didn't.
Thank you for all your help. I did learn a little even if it wasn't the direct solution. Now if only I could get Disk Utility to restore my old image without giving me crazy errors... But that's another issue altogether. ;-D

Disk utility will not boot using COMMAND R. It won't give me the 'ERASE' option when I open Disk Utility. How do I wipe my hard drive?

Disk utility will not boot using COMMAND R. It won't give me the 'ERASE' option when I open Disk Utility. How do I wipe my hard drive?

If you're truly running 10.6.8, there is no Recovery partition - that didn't come along until 10.7x.
You'll need to use the set of gray discs that originally shipped with your model. If you don't have them, you can always get your serial number from the bottom of the casing and call Apple to get a set of replacement discs. These will run you about $20 + shipping & taxes. Once you have the discs, boot from Disk One and use Disk Utility to erase your HD and then reinstall whichever version of OS X that shipped with your model. No way around of getting the discs.

Disk Utility is not working for me.

I have had a nightmare trying to install a Boot Camp partition on my brand new 27" iMac with 3TB Fusion Drive and running 10.8.4.
When trying to use Boot Camp Assistant, it would start the partition, then not finish. I quit BCA, tried repairing both the partition and the disk, that didn't help either. So I went into Disk Utility to create a new partition with no file system on it, assuming I could just use Boot Camp Assistant to format it when the partition was created. It would start, but not finish. I tried Repairing the disk and the partition, neither helped.
So I booted with CMD+R, launched Disk Utility, and tried to create a 500GB empty partition. It started and just never quit, so I CMD+Q, got out of it, went back to Disk Utility, I found that I now have a 1.22TB empty partition and a 1.78TB Mac Partition. This is probably my own fault, I should have just let it run, but after 20 minutes, it wasn't moving.
I figured that would work okay, so I tried installing with BCA, but found it's looking for an HFS+ partition to resize and wouldn't work with an empty partition, so I figured I'd just format the empty partition as HFS+ and install with BCA. Unfortunately, I can't get Disk Utility to format the partition. I select the empty space, it puts a white block on it like normal titled Untitled 2, I select Mac OS Extended (Journaled), hit apply, something flashes very briefly over the "capacity" line, and then nothing happens. Hit revert and it shows up with the Macintosh HD partition and the empty partition. No matter what format I choose, nothing happens. If I try to exit, it tells me that changes have not been saved.
I'm trying to just extend the Mac partition, but the resizing option is not available. I can't drag it to cover the Free Space partition, I can't type in the Size to resize it by number, I can't do anything. I've tried to repair the disk and the partition, nothing happens. I can't reclaim the space no matter what I do.
At this point, all I want to do is recover the entire space of the hard drive for Mac OS. I'll try again with Boot Camp Assistant after Apple works the kinks out.
Any help would be appreciated.

The Boot Camp Assistant in 10.8.4 should be able to partition your 3TB+ drive so you can have Windows. If Disk Utility is not working then your disk is corrupt. Backup all your data using Time Machine. Erase the volume and restore from Time Machine backup. You can use the ‘OS X Recovery Disk Assistant’ (http://support.apple.com/kb/DL1433). Open Recovery Disk Assistant and follow the on screen instructions to create a Recovery HD on the external drive. When the Recovery Disk Assistant completes, the partition will not be visible in the Finder. To access the external Recovery HD, connect the drive, then restart the computer and hold the Option key. Select Recovery HD from the Startup Manager. You would need to re-install Mountain Lion up to 10.8.4. Then ran Boot Camp Assistant and then install Windows. Once you have confirmed that Windows is running then open up Migration Assistant (in the utilities folder) and migrate your Time Machine backup back on to the hard drive.

Hard Drive Reads in Disk Utility but not in Finder

I have a Seagate FreeAgent hard drive that is configured to NTFS. I use software to read and write to this on my macbook pro. I have plugged my hard drive into my macbook this morning and it will only read in Disk Utility, and not show up at all in Finder. I have plugged it into another macbook and have the same thing. Tried to do disk repair and it said it was repaired and operating normally, but still not opening in Finder. I also tried it on a Dell running XP and same thing, doesn't open as a folder but shows as operating normally in the XP's disk utility equivalent. I have tried finding an answer elsewhere but can't come up with anything. Besides taking it for data recovery, is there anything else I can do or try to fix without compromising the data?

You might get more help were you to post in something like the MacBook or OS X forum. This forum is for OS 9, an archived Apple Macintosh operating system.
That said, it sounds like your drive might be dead. When you say that you can see it in Disk Utility, you mean that it shows up in the column on the left? When you repair it, can you hear the drive spinning up?
Can you try making an image of the drive to see what happens?

Disk Utility Partition

I need to reformat an external hard drive. Disk Utility does not show a Partition tab, which is what I believe I need to do this. Does this mean my version of Disk Utility is faulty, and if so does anyone have ideas as to how I can fix it?
Thanks

Hi
See http://discussions.apple.com/thread.jspa?messageID=4421396 as it seems you need to click on the name of the external disk (e.g 149.1 GB LaCie etc) for the Partition tab to come up. Because it's an external drive, it shouldn't require DU being run off the install disk.

My Disk Utility is not working, also can't eject a mp3 player

I attached the mp3 player to the computer and downloaded some music on it. This went OK. When I went to eject it by right clicking on the player and choosing eject, it would not eject. So I opened Disk Utility to try and eject the disk and now find that Disk Utility won't open.
When I do force-quit Disk Utility the message says Disk Utility is not responding so there is a problem with Disk utility.
This is the first time I've had problems with Disk Utility and with ejecting a disk.
I don't want to pull the mp3 player out as it could do something funny to the disk as that happened before when I accidentally removed the mp3 player without ejecting it first.
However, the mp3 player has been OK for a while now and this happens.
What can I do?
Should I restart the computer and see if that solves the problems?

Are you receiving an error message when you try to eject via the Finder? Normally you should get a message along the lines "The disk * could not be ejected because the application * is using it" or something like that.
You could just shut down and unplug the mp3 player then, but it would be interesting to find out the cause of the problem. Do you know exactly what files are on the player?

G4 disk utility does not see hard drive

I am helping someone with a G4 Quicksilver. She is running 10.4 but only has disks for 10.1 and 10.2. When I boot with the 10.2 CD, disk utility does not see the hard drive. I was thinking of connecting her computer to my MacBookPro (Intel, 10.5) via target disk mode and then running Disk Utility. Is that crazy? She is suffering from slow startup and grey screen. I've disconnected the periferals, safe booted, reset PRAM. She really needs Disk Utility.

with the 10.2 CD, disk utility does not see the hard drive.
Disk Utility from 10.2 should see the hard drive (the drive name should appear in the left box). If it does not, the drive is malfunctioning or has a loose cable.
If you attempt to Verify, it will complain that there are illegal values in reserved fields in several different record types. Using this older Disk Utility to repair a 10.4 disk may cause more problems than it solves.
As Tom \[Texas Mac Man] says, you should only repair 10.4 and later disks with 10.4 and later Disk Utility:
HT2648- Only use Mac OS X 10.4-compatible disk utilities with Mac OS X 10.4 volumes
• If you boot the regular Hard Drive (no CD/DVD required) while holding down the Shift key, it will do a quick check of the Hard Drive, then boot up in "Safe Mode". This will fix any simple Disk problems.
• 10.4.3 and later can do a Disk Utility Verify of the Boot drive, "live" (but cannot Repair "live").

My disk utility will not let me highlight journaled in the drop down menu. I need to erase the entire mac for re sell purposes.

You need to be booted from another source as you cannot delete or reformat the drive you are booted from. See if you can either use the original install disks (Snow Leopard or earlier) or internet recovery (Lion or later) to boot from and then be able to use the Partition tab to partition and format it correctly.

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.
