Disk Utility doesn't play on PCs

I recently used disk Utility to burn PDF files and movie files. The files were such that they would open on a PC normally if sent in an email or on a webpage. However, when I gave the disk to my friend, it appeared as a blank disk when she used it in her PC. However, when she tried another Mac, all the files were there. Is this common of the Disk Utility feature? Is there a way to burn the disk with disk utility in order to have the files appear on both a PC and Mac, or do you need something like Toast to burn those sort of files?
Thank you.

When you create a blank disc image file in Disk Utility a dialog appears. A drop down menu labeled Partitions will be in the dialog. Choose the option for CD/DVD with ISO data.
From the Finder just insert a blank disc in the optical drive. A dialog will appear asking what you want to do. Select the option to mount on the Desktop. You can then copy files to the mounted disc. After all the files have been copied select the disc icon and select Burn Disk from the File menu.
If you use the Mac Help selection from the Finder's Help menu you can locate help on burning CD/DVDs. You will find similar help from Disk Utility's Help menu on using DU to burn CD/DVDs.

Macbook Pro: Disk Utility doesn't see my HD

Hi guys,
My Macbook Pro has been running slower lately, but I honestly didn't think too much about it...until today. It's just over a year old, running Mac OS X, and I mostly use Safari as my browser, but I have to use Firefox for my online classes. Today, Firefox froze up and quit responding, so I Force Quit it. A few minutes after this, Safari did the same thing, and then it was my entire desktop. Nothing was responding; I had to shut down by pushing the power button.
And then, it wouldn't turn back on. The chime sounded, the apple appeared, and the spinning circle underneath it. And it spun, and spun...until a generic "stop" symbol replaced the apple logo. I immediately shut it back down and did an online search. I followed every fix recommended for this issue. I tried reseting the PRAM, and then the SMC, and still the same thing happened. I tried to boot in Safe Mode, and if seemed to be working...right up until an hour passed and nothing new was happening. I shut it down again, and tried booting from the install disc of Snow Leopard. That worked, and I tried to do Disk Utility with the intention of following the online apple directive of running first aid on my HD. Except Disk Utility doesn't see my HD, only the boot disc and DVD drive. I'm guessing this is a bad sign. I tried calling Apple Care, but they are closed right now. I will call them in the morning, but in the meantime, I thought I'd see if anyone here had any advice I haven't already tried. Sadly, I haven't run Time Machine in...months. I'll end up losing a lot of stuff because I just didn't do that if my HD is toast.
Any suggestions?

Sure seems to be a failed(ing) hard drive. If you happen to get it into safe mode again, the ONLY thing you should immediately do is copy off your Home folder to an external USB disk, SD card, something. Then just get it to an Apple store for check.
Try to copy your files off first and don't try anything else to get at that disk until you copy your home folder. If the disk is failing and you're trying to do things to it you'll loose the chance to get that data.

Disk Utility doesn't refresh when inserting new DVDs

I'm in the process of copying a few DVDs by making an image of them first and then burning the image onto a blank DVD through Disk Utility.
After I'm done with one and insert a new DVD to copy, Disk Utility doesn't refresh to show me the new disk is in the drive. Is it normal?
If it is, is there something I can press so that Disk Utility manually refresh its listing of drives?
I find that quitting and restarting Disk Utility just to make a new image is so inefficient.

I am suddenly having the same problem. When I insert a blank disc either cd or dvd it does not show up in the left column in disc utility. I have tried closing and then relaunching disc utility but nothing. The disc shows up on my desk top but not in disc utility. I fear this is a Snow Leopard problem. Toast has no problem recognizing the disc and burning to it.

IPod Shuffle not recognized, device not recognized, disk utility doesn't...

...disk utility doesn't show up.
It's all on my wife's computer as it's her iPod. Up until yesterday - and she didn't change ANYTHING - iTunes 7.01 had no problem wiht the iPod. Today, however, iTunes nor her Mac recognizes the iPod. Can't do a thing with it. It displays a nice green light, but that's it. All connections checked and re-checked. Looked at the disk utility and there's no image for her iPod.
I plugged it into my own Mac and iTunes 7.02 tries to upload/access her library from her iPod and 1) after an interminable wait, say four to five minutes, it recognizes that there's a shared library available, and 2) then it says there's some firewall that won't let iTunes access the liberary.
I don't have an iPod of my own, so my experience is really limited. She uses her iPod all the time and, again, hasn't done anything different than she did last night.
What is to be done? Thanks in advance for GOOD tips.

Turns out she's running iTunes 7.1...
Still nothing.
Anyone out there, please?

Airport Disk Utility Doesn't See External Drive, But Airport Utility Does?

Hey! I am a recent Apple convert and just got a brand new MacBook and Airport Extreme. I am trying to get my Maxtor OneTouch 320GB HDD to work with the Extreme, but to no avail. The Airport Utility sees my HDD, but the Airport Disk Utility doesn't? Any hints/tips on how to fix this problem? Any help is appreciated! Thanks!

All I can think of is that the drive is formatted in NTFS which I have heard cannot be read by the AEBS(Airport Extreme Base Station), but I am confirming this right now in a different message. If you can copy the files, format your drive in HFS+(the Mac's standard file system), then reload the files. See if it works and reply back.

Lion Disk Utility doesn't finish erase

Since installing Lion (clean install) disk utility doesn’t finish erasing or partitioning external disks. I used the disk utility from the install drive to erase the internal drive before installing Lion, this worked fine, but ever since it failed to erase any of my external drives. It starts of as normal but the progress bar stops half way and just never finish. Disk Utility does respond.
I tried different format options, repair and verify but none of the processes finish.
I went back to the install drive that I used to erase the internal drive before Lion install and it also didn’t want to finish.
I copied the old disk utility from Snow Leopard to my desktop, it opens with a warning, but gives the same outcome.
Any advice?

I'm having the same problem on my late 2010 Air with Lion installed over Snow Leopard.
I've tried several usb memory drives and several external harddrives...all the same problem with the progress bar getting stuck halfway. wether I select 'partition' or 'erase'.
the 'genius' at the mac store told me that he advises a clean install of Lion. I did...or I thought I did but all my files were still in place and the problem was still there. Guess I will have to wipe the drive first.
Also, unable to repair permissions on the MAC drive.
But it is remarkable how few people seem to experience this problem thus far. A google search hardly returns any results.

Disk Utility doesn't recognize HD. Installed new one, same problem.

Hello,
I have a MBP. It suddenly wouldn't boot up, and had the flashing question mark folder upon starting up, so I figured that the HD needed to be replaced. I ordered a brand new drive, and when I try to install Leopard, it doesn't see the new hard drive. I open Disk Utility to partition the drive to GUID, but Disk Utility doesn't even see the new drive. Just my optical drive is listed.
I hooked up the old hard drive externally to another mac, and it appears to be working just fine. So it isn't a bad drive as I had originally thought.
What else could be wrong? The laptop fails to see any internal hard drives. Is there anything else that I can do to fix this problem? Thanks.

Purely conjecture, your serial ATA controller may be bad (or the cable). I assume nothing shows in System Profiler/Hardware/Serial-ATA either. Maybe try the SMC reset?
-If the computer is on, turn it off.
-Disconnect the AC Adapter and remove the computer's battery.
-Press and hold down the power button for 5 seconds and then release the button.
-Reconnect the battery and AC Adapter.
-Press the Power button to restart the computer.

Disk Utility doesn't recognise inserted DVD-R DL

I upgraded to Leopard from Tiger a few week ago and Disk Utility has been working fine for a while. I bought a few blank DVD-R DL disks with 8.5Gig storage capacities, but, when inserted, Disk Utility doesn't show them in the top of the pane on the left side.
It shows the Super Drive, but doesn't show an inserted DVD below it like it usually should.
Any suggestions?
Message was edited by: jemorris55

Alright, so instead of burning to the disk specifically, I burned to the superdrive which automatically burned to the disk. It worked alright and now that the DVD has something on it, its icon pops up in Disk Utility. I don't know why it chenged...

Disk utility doesn't encrypt

Disk utility will create a custom disk image on my external HD, but won't encrypt it. I've followed the instructions step-by-step for creating a secure, encrypted disk image several times and it always ends up the same: the disk image is created in the right place with the right name and size, but it doesn't require a password to open it. What am I missing here?

Don't put the password in the Keychain. If it's already there, open Keychain Access and delete that image's entry.

DIsk Utility doesn't allow creating a partition

Hi all,
I just bought a new MacBookPro and installed Mountain Lion yesterday. I decided to use a encrypted file system (File Vault). So far everything worked fine.
This morning I decided to do a clean install, as Migration Assistent carried over some data I do not need.
So I booted into Recovery Mode, selected the harddisk and chose "Erase". As I wanted an encrypted volume again, Disk utility asked me for a password which I specified. Immediately after clicking ok, Disk Utility said "Not enough RAM to complete this request". After clicking OK, my partition went and since then I am strugglign to find out how to activate it (data not important, as everythign backed up).
Apple Care also doesn't knwo what to recommend anymore.
Here's what I tried:
1) Command+R boot and Disk Utility
2) Boot from external HD and Disk Utility
3) Internet Recovery (ends with error)
4) Delete PR
The strange thing is that Disk Utility shows Macintosh HD on the top level with the option to partition (it doesn't show any indended partitions) but all options are grayed out. It's like Disk Utility somehow confused Parttion with physical drive and now gets confused.
Any other idea other than sending the macbookPro back to Apple?
Thanks
Matt

You should of taken the encryption off before you started that proccess. That is one thing they don't tell you. Never try to modify an encrypted partition.
You may have to boot to the Internet (Online) Recovery HD system lto Re-Partition the drive as one partition.
Hold down Command+Option+r keys at boot and keep them held down until you see a spinning globe in the center of the screen, then you can let them up. Have the computer WIRED to your unternet router.
Once that loads open disk utility and select the Drive Name (Not volume name, IE Macintosh HD) and then the partition tab and select One partition from the Partition Layout drop down.
If that doesn't work then the drive is FUBAR.

Disk Utility doesn't run from installation dvd.....

hi there:)
i ran a scheduled maintenance check using Onyx. It turned out that the disk could not be verified and it had to be fixed by inserting the installation dvd and running 'disk utility'. i inserted the dvd and ran the 'disk utility', however, it quit unexpectedly. the following message came up:

Rik,
Please reread my first post carefully & make sure you follow its instructions closely. The "Repair Disk" step (not the verify one) should be run while your Mac is started up from the install disk, then the "Repair Permissions" step should be run after you have restarted normally.
Some background info that may be helpful:
Disk Utility (& all such disk utilities) must temporarily "unmount" a disk to affect a repair of its file system (which is what the "Repair Disk" step does). Unmounting a disk makes it unavailable for normal use. The disk containing the operating system that is currently running the computer (the startup disk) cannot be unmounted. This is why the "Repair Disk" button is grayed out if you run Disk Utility with your startup disk as its target.
Repairing permissions does not require unmounting the disk but it does require a healthy file system, which is why the disk repair must precede it. Apple recommends repairing permissions on the start up disk while booted from it, which is why it should be done after restarting normally.
The verify steps do not actually repair anything. They just run the checks that the repair steps run to determine if any repairs are needed & report the results of those checks.
The routine that repairs permissions is part of the OS itself. Disk Utility, Onyx, & all other such utilities that repair permissions actually just tell the OS to perform this routine. Thus, it doesn't matter which one you use to do this repair, nor is one utility any better than another at doing this. So if you prefer, after restarting after doing the disk repair from the install disk you can do the permissions repair with Onyx.

Disk utility doesn't open, trash works incorrectly.

After updating to 10.7.3 I have noticed that Disk Utility no longer opens. It pops up into the utility bar for a few seconds, bobs up and down a couple of times, then disappears. The next time I click on Disk Utility I don't even get that much of a response. It just doesn't open. No error report, no pop ups saying that it can't be opened - Nada. I can't use disk utility AT ALL anymore. I've tried Zapping my PRAM, but that's about it.
The other thing I've noticed is that any time I put something into the Trash Bin it automatically tells me that it will delete the item - it doesn't sit in the trash bin like it used to until you manually delete it. The only time I can get it to behave normally is when I am using an external drive and I put something from the external drive into the trash bin.

Repairing the permissions of a home folder in Lion is a complicated procedure. I don’t know of a simpler one that always works.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
chmod -R -N ~
The command will take a noticeable amount of time to run. When a new line ending in a dollar sign ($) appears below what you entered, it’s done. You may see a few error messages about an “invalid argument” while the command is running. You can ignore those. If you get an error message with the words “Permission denied,” enter this:
sudo !!
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
Next, boot from your recovery partition by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the recovery desktop appears, select Utilities ▹ Terminal from the menu bar.
In the Terminal window, enter “resetpassword” (without the quotes) and press return. A Reset Password window opens.
Select your boot volume if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select  ▹ Restart from the menu bar.

Erase button on Disk Utility doesn't work

II'm trying to erase my external HDD so I can use it to restore a backup of my HDD , since there's a problem with my HDD and my MacBook Pro is stuck on startup, but the erase button (is not grey, it looks functional) doesn't respond. I press it and nothing happens. What can I do? I need to backup my files ASAP

Connect the external drive to another mac ( a friend maybe?) and re-format it using that.
I'm not 100% clear on what you're trying to achieve here, but it sounds like your MacBook HDD is corrupted. Make sure you've tried repairing the HDD using disk utility in the recovery partition. This will tell you if the disk is usable. It may repair it and return your system to normal operation.
If your HDD is corrupted or damaged you may have trouble backing it up to the external drive anyway.
Personally I would remove the HDD, replace it with a new one and re-install OS X onto it. While you're out getting a new HDD, pick up a SATA to USB drive caddy that will allow you to connect the old HDD to your new restored Mac via USB. If it's readable then you should be able to copy data off it.
Your ability to re-install to a new hard drive will tell you if the problem was with the old HDD or with the Macbook itself.
If the old HDD is not readable you may have lost your data, or you may need to go to a professional data recovery service. This is why backups are essential. I would recommend using your external drive for backups with Time Machine.

Disk utility doesn't allow partitioning of internal HD

After having succesfully installed a Win7 partition with bootcamp I've now got 2 partitions,
the Macintosh HD aund the Bootcamp partition.
I'd now like to split my Macintosh HD partition (to get one separate for data only).
However, in the disk utility this option is not selctable:
+ an - are greyed out,
Partition Layout dropdpown menu is greyed out,
Name format and size are greyed out.
(Everything works fine on the mac and also the Volume & Rights checks by the disk utility were all o.k.)
What is the reason for this behaviour and what can I do in order to split in two partitions?
Your help appreciated, thanks.

Disk utility doesn't show external Time Capsule harddisk

Hi.
With an older OS X, it was possible to use disk-utility for making some changes at my TimeCapsule(3rd.Gen.)-harddisk.
Now i tried this with the latest version of Yosemite. I think, at the 1st view to to disk utility window, there was an TC-ikon shown under the SuperDrive-ikon. But some seconds later it was gone! I tried it again after restart my iMac an the TC, but every time finder-window and disk-utility-window looks like this ..
... with added comments in green ("Finder"-window, "disk utility"-window) and red (lost "TC-Harddisk?"-ikon).
I tried this also with a MacBook-air (newest version) - same result
What happened? Is it a Yosemite-Problem?
Can I do something with the terminal-app to get the connection?
<<<---- I posted this Nov.2014 at Mac OS & System Software / OS X Yosemite
Today I connected an USB-Stick with my TimeCapsule. Then I opened Disk Utility and was happy - for some minutes.
At the window of the Disk Utility I saw the TC-Harddisc an the memory-stick too.
But when I tried to add an partition to the TC-Harddisc, it was gone away.
I closed-and-started the disk Utility again - now TC-Harddisc was shown.
I disconnected-and-connected the memory-stick again - now TC-Harddisc was shown at the disc-utility-window.
Thanks for Help!

You cannot partition a TC disk from disk utility in the Mac.. that has always been the case.
What you did last time is partition the sparsebundle.. that is a virtual disk created by the computer.. merely partitioning a virtual disk is pointless.
You simply need to create another sparsebundle or dmg file to use as virtual disk.
But the fact that Yosemite continually loses connection to the TC .. oh yeah that is because Yosemite is buggy.
Reset your TC to factory.
Do this manually..
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Then redo the setup in the airport utility. Use short names with no spaces and pure alphanumeric characters.
Same with passwords only longer.
I recommend you then mount the TC in finder manually by its IP address if at all possible not by name.
The problem here is the IP must be static which it is by default if the TC is the main router but it will have to be specially setup if the TC is bridged.
Use Go, Connect to Server.
SMB://10.0.1.1
When asked for the disk password type that in and do not forget to save it in the keychain.
Then you can mount a TM sparsebundle in disk utility if you want.. although I suggest that is pointless other than to verify your backup.
Do not partition it.. that is not helpful at all.
