No access to Disk Utility

Feeling rather naive, I need help accessing Disk Utility. It will not launch from my Utilities folder when I click on it (nor will System Profiler, nor Keychain Access). I suspect I need to return to the Tiger Install Disk. But I surely don't need to reinstall the System. Thanks in advance for the help.

Does your hard disk appear on your desktop? If it does, you can click once on it and select Get Info from the file menu. This will tell us exactly how space is used. Double clicking the hard disk will reveal in a status bar the number of MB or GB free. If that status bar is missing, you can activate via the View menu. If that doesn't give you that option, click once on the jewel in the upper right hand corner to reveal more of the window first.

For whatever reason you don't have the Yosemite version of Disk Utility which is 13. I suggest you reinstall Yosemite.
Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Download and install the 10.10.1 update.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Check that you have the current version of Disk Utility.

Mac-formatted external HD only access with Disk Utility

Hello!
I read a lot about problems with Mavericks and WD harddrives. But i did not found anything about my problem:
- bought a new HD and formatted with Disk Utility
- copied all important data to it, all fine
- next day for my surprise i couldn´t see this HD in Finder
- looked in Disk Utility and the HD is there
- if i click on the drive and "open" then i can see it in finder and have access to all data, but if i click on "reveal in finder" i can´t see it!
- i started CarbonCopyCloner and did a complete backup to a new second backup HD, CCC recognized the HD and everything worked fine
- now the backup HD has the same problem, i can see it only in Disk Utility
- it seems that the error moved from one drive to the other, so my guess is it has nothing to do with brands or a hardware failure
- i´m searching now for hours but i don´t find a solution
- i now have one (very important) data HD and a backup HD as a clone with the same problem
- all other HD´s i have are showing correctly in finder!
Does anyone have any ideas?

After hours of searching this is the solution:
Open Terminal, then
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder
sudo chflags nohidden /Volumes/"Name Of Drive"
killall Finder
defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder

Can Time Capsule hard drive be accessed with Disk Utility? I'm having issues...

How does one mount , inspect , verify , and possibly repair a Time Capsule hard drive with Disk Utility ?
My 500Gb 1st gen Time Capsule ( used wireless with Airport) has quit backing up new data . ( iMac Core2Duo, Snow Leopard) . TC says it needs 238 Gb of available space, but only has 35 Gb available. So it quit doing new incremental backup altogether. It's almost like it wants to start over.
Airport connection seems good. Time Capsule seems healthy enough ( for being 3.5 years old) . I really dont want to lose the data on the existing backup.
What is the nature of this glitch ?

I'm sorry , LaP , but " Time Capsule become too full " is not the cause of my problem .
In fact, I just got done pruning the iMac system hard drive a little to free up some 10 Gb of new space , yet created only maybe 1-2 Gb of new data to archive. The TC had been doing regular daily backups without issue and Time Machine was showing me stuff from about ten days back.
The TC informed me it needed 235 Gb of space but only had 34 Gb available. That 235 Gb needed is totally in error. My problem more resembles corrupt hard disk directories . Maybe Permissions ? which is why I asked about using Disk Utility.
Yes, I do need a newer larger TC, but pigs don't fly and money does not grow on trees to make tha happen. The backup I have now is fine and should work if I need to restore anything in the forseeable. New data will not be archived, alas.

Cant access disk utility

While trying to access the disk utility during start up, I've tried both the Command + R, and holding the Option button. Command + R does nothing. Option button takes me the a screen where I should be able to select disk utility, but instead I can only click Macintosh HD. This does not give me an option to reset my macbook pro.
Ultimately my goal is to reset my laptop, but as this is the only method I know of I have become quite frustrated. Can anyone help?

If you indeed are running Snow Leopard as you indicate, then the COMMAND + R option is not available to you. You need Lion OSX or later.
If you want to Verify and Repair your MBP HDD, then you will have to use the original OSX install disk that came with your MBP.

My WD hard drive won't "mount" it shows in disk utility but can't be repaired. I'm thinking this is a software issue since the disk is being recognized.

I have a WD drive that won't "mount". Tried repairing, turning off and back on, unplugging and nothing has worked. Can anyone help?

The WD Passport has no independent power supply, relying instead on getting power from a USB port on the computer. AS the drive ages it can need more power to spin the platter and many USB ports on notebook cannot provid that much.
Anther issue is the WD drive itself. WD uses an odd proproprietary formatting scheme that makes the drive not always behave like typical Mac drives.
If the drive contains nothing you need to access, use Disk Utility to reformat it to "Macintosh Extended (Journalled)"
If the drive contains important data, there are a couple of inexpensive ways to get more power to it:
1) Get a "Y" conenctor cable like this:
http://eshop.macsales.com/item/OWC/USB2AYMBPB/
It draws power from two USB ports and ofter that is enough to make the drive work.
2) Get a powered USB Hub:
http://eshop.macsales.com/item/NewerTech/USB2HB7PRO/
It has its own power brick and that is usually enough to get an older USB external drive recognized.

Internal Hard Drive Disk Utility Repair Problem

Hello all! I'm really hoping someone can help me out because I'm in a bit of a panic right now about all of this.
For starters, I have a Mid-2007 20" Intel based iMac.
The other day, I turned on my computer and got a flashing question mark and the computer would not boot. Luckily, I have an external hard drive, so I went through the process of using the Install Discs to use the Hard Drive to start up my computer. Everything worked out and once the computer turned on, I was able to access my Hard Drive and had full access to my files. I powered down my computer as I had to run out the door for school and was planning on backing all of my files up on my external hard drive tonight.
Unfortunately, when I turned on my computer, my internal hard drive had disappeared. I can only start the computer with my external drive plugged in.
I accessed the Disk Utility, and it was the first place I was able to locate my Hard Drive. On the left hand side, underneath the external drive, it simply says "Media". I cannot click on ANY of the options under First Aid and the only thing it seems I can do is Erase the drive.
I would REALLY like to avoid this option, as there are nearly 5 years worth of documents on this computer.
My S.M.A.R.T. Status says Not Supported, and it's saying that the Total Capacity is 0 Bytes.
I suppose I should also mention that with the disc I used I am now running OS X 10.4.11, but previously, I was running 10.5. I can't remember the last decimal place. I don't know why there was a difference, as I used the same disk...
I have NO IDEA where to go from this point besides taking it somewhere to see if my files can be recovered.
Can anyone help me out here?
If you need any more details about my computer/the actions I took, just let me know.
Thanks so much!!

If you cannot access the internal HD then it may have crashed, I am getting you may not have been backing up either so if it has crashed and you don't have a backup then your data is probably gone. If you can get the internal HD to show up again before you do ANYTHING else back it up using Time Machine (assuming you use 10.5.x or above) or create a clone on an external HD using either SuperDuper or Carbon Copy Cloner.
My recommendation at this point is to take the machine into and an Apple Store or AASP to have it looked at.

My drive collapsed. I have an external hard drive. How can I put all my files there, using disk utility?

So my MacBook Pro collapsed one day, and it turns on but only "Restarts" and shuts itself down on the procesa. The only thing I have access to is that 'Command + R' thing. There I tried "Verifying" and "Reparing" the Diak but the message of "Cant repair disk backup as many files as possible, reformat the disk and restore" popped up. So I have am external hard drive with more than enough space to put all of my files in there. my question is: HOW DO I DO THAT? from disk utility. Can somone please help me? Please! Step by step cause ptherwise I will mess it up and I really dont want to lose all the memories I have in my computer.

After you restart so you have access to Disk Utility, with the external drive connected, choose the external drive from the left sidebar of the DU window. If the drive has not been formatted for the Mac, choose Partition from the buttons top center of the main window. Give the drive a name, you can leave it as one partition if you like, make sure the format is set as Mac OS X Extended (Journaled), and the partition table is GUID. Then Apply and acknowledge that you know this will erase the disk.
Then go to the button that says Restore. Drag and drop the internal drive, Macintosh HD is most common, to the Source box, and drag and drop the external drive to Destination box. Then Restore.
That will create a clone of the internal and that will be a bootable clone.

Repair disk utility

I checked my macbookpro with Onyx as usually, result: minor problems and disk needs to be repaired. Cmd + R and this time I can't access to the disk utility, simply the apple logo disappears and a symbol appears, nothing happens.

Apple/Grey Screen Stuck - Disk utility - back up

Hello,
So I was on my computer and it randomly turned off and turned back on and stayed on the apple/grey screen. I've done the vram reset and ended up where I can boot up the installation disk. I've gotten to where I can access the disk utility and repair/verify disk permissions but ended up getting the error code: 'Error: no valid packages.' From my hard drive, all I need are pictures and videos that I had just backed up the day before. Could someone help me (easiest way for me to follow is through steps) on how to just back up specific files or folders (i.e. pictures folders)??
Thanks again for your help!

Mac stuck on apple logo, can't boot to disk utility...

iMac 2010 running Yosemite.
Stuck on apple logo with loading wheel but does not progress from here. Have booted in single user mode and proceeded to do the /sbin/fsck -fy steps until the volume was reported as okay, this did little to help. I can boot using the option key and can see the hard-drive and recovery partition are there however cannot boot using command+R to access the disk utility as it simply stays on the apple logo.
Was wondering if anyone could advise what to do from here.
Thanks in advance.

Have you tried safe mode?

I have a late 2012 iMac running osx 10.8.5. I keep losing access to my internal hard drive. I can reboot and regain access and it will last for a few minutes or hours. Disk utility does not seems to help.

I have a late 2012 iMac with an I5 precessor running OSX 10.8.5 and a 1tb internal hard drive. I keep losing access to the internal hard drive/startup disk.
I can reboot and everything operates as normal for a few minutes or hours but then I lose all access again to anything on the hard drive. The computer is still up and running but no files can be accessed and certain websites cannot be acessed even though internet access appears to be normal. Disk utility can only find permission errors related to iTunes which can be repaired only to come back at the next scan (I would not think permission errors would have anything to do with the hard drive crashing). It does not seem to matter what program I am using at the time access is lost and it can lose access sometimes right after reboot when no program is running.

You will need to boot into the Recovery Volume (command - R on a restart or hold down the option/alt key during restart and select it) to run Disk Utility/Disk Repair.

How do I access Disk Utility for 10.7.1?

How do I access Disk Utility for 10.7.1? I found it in the forums a few weeks ago, used it, then lost the directions. This is a last ditch attempt
to use OS Lion. I parted my hair incorrectly when I installed and have been plagued by the dread rainbow spinning ball in EVERY application. Yes, every. Name one, Safari, Firefox, Text Edit, Mail, Excel, Word, iTunes, Garage Band, Calculator, Calender, iPhoto....yes, every, and I cannot
find a solution that works. I have back up files on two different hard drives 500 gig and 1 terrabyte with all my music, photo and writing files.
I am a writer and a musician so imagine the frustration. OS 10.6 is an option of course. My dedication to Apple and each new OS is deep so
I am hoping that somehow there will a fix, an upgrade, something that does not require me to go bac to the much more endangered species named OS.
hahhaa! Just stalled waiting for the ball to finish with it's random spinning.... SO, this is like a last desperate .... it just did two more stalls.
NO OTHER apps running, just little Firefox holding on for dear life, last desperate request for a fix.
MacKeeper has been great in sending helpful directions for getting the Antivirus to work after it mysteriously decided to stop working, Quite MacKeeper, go to Activity Monitor, force quit helper, start up MacKeeper and run program. It works!
SO before my third stall stops me, please post directions to open disk utility in administration mode so that I can do any further repairs that have not worked by using it from the open system. Also keychain synching stopped working with Lion.
Thanks to any and all who can help.

Press and hold Command-R keys and reboot. You'll then start up in the Lion Recovery HD. You'll find Disk Utility there.
Command-R to the rescue.
Just hold down Command-R during startup and Lion Recovery springs into action. It lets you choose from common utilities: You can run Disk Utility to check or repair your hard drive, erase your hard drive and reinstall a fresh copy of Lion, or restore your Mac from a Time Machine backup. You can even use Safari to get help from Apple Support online. And if Lion Recovery encounters problems, it will automatically connect to Apple over the Internet.

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

Yes, sharing a TM disk is a bad idea, and disks are cheap enough so that you don't need to.
