H.D. Clicks When Booting But Disk Utility Says "No Problems"
My friend installed a new 300 gig Seagate on his G4 a couple of months ago. It has worked fine until now. Suddenly, it won't boot up from the HD -- just clicks. He gets the spinning ball and it freezes up. HOWEVER: (1) The icon does appear on the desktop and (2) When he starts up from the CD and runs Disk Utility, D.U. recognizes the H.D., checks it successfully, and reports "No Problems Found." He can hear it spin up and everything just fine when he is checking it with Disk Utility.
So, it seems to go into the "clicking and spinning ball syndrome" only when he is trying to boot up from it. Any ideas? Thanks!

I have a MacBook that needs its internal hard drive's Macintosh HD partition repaired, as the boot screen freezes on startup. I am running a separate, working mac OS from an external hard drive in order to run disk utility and repair the MacBook's internal OS. The issue is, it has dismounted the internal Macintosh HD partition, and won't remount. And in addition to that, the Verify Disk option returns with, "The volume Macintosh HD appears to be OK." I've run Verify Disk and Repair Disk a few times, all with that same result. And the internal OS still won't boot.
I have attempted to make a disk image of the internal Macintosh HD partition and save it to my external hard drive so I can wipe the internal hard drive clean and restore the image, but I receive errors when trying to create the disk image, and when trying to erase the hard drive (I know, I should try to erase the hard drive when I haven't made an image. When I tried to erase the hard drive, the image wasn't done and I thought it was. I got an error for erase, and I got an error for making the disk image) I have tried making a disk image multiple times and haven't been able to create one.
There is also a boot camp partition on the internal hard drive which is of no importance as to whether it stays or is erased.Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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 Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/. -
Disk Utility says no problems but Diskwarrior disagrees
Need some advice. I ran Disk Utility yesterday to verify my drives before upgrading to 10.4.4 on my Dual 2GHz. It came up with some errors but said it couldn't fix them. Went to Diskwarrior which also said it couldn't fix it. Did a safe boot which is supposed to force an 'fsck' but the system never fully booted from that, probably failed at the fsck (the fans turned on full blast at the grey bootup screen then eventually powered off by itself). When I rebooted, I ran Disk Utility and it now reports the drive is fine. Diskwarrior still scoffs at that though.
Disk Utility said something about File Allocation Table mismatch.
Diskwarrior said the directory structure could not be repaired.
SMART says the drive is fine.
TechTool Pro reports a Bitmap mismatch and could not repair the drive.
Thing is, I don't see any problems with the drive at all. System boots fine and there are no corrupt files. It's a 3 month old 300GB Seagate so I don't think it's a hardware problem. But I've had some kernel panics related to my video iPod (the one where the G5 kernel panics if you have low space left on the iPod) which is where I'm guessing this all started from.
I've left it for now with Retrospect backing up the drive to a new external 250GB drive I had to buy just for this. I was planning on formatting the problem drive, testing it again and then restoring the Retrospect backup. (The only issue I've had with Retrospect is I Duplicated the problem drive to that new drive and had about 4000 files with different dates. I'm hoping that doesn't happen using the Backup function instead.)
Is this the right path? Or anybody think it could be a hardware issue? I've never done a full system volume backup with Retrospect, will I run into problems making the restored drive bootable again? And last, are there any other programs I should try?
BTW, I thought Journaling was supposed to fix all this!!Welcome to Apple Discussions!

Disk utility says widget problem, but I have no widgets?
Everytime I do a verify and repair permision I get the same thing over and over, widgets permisions and so on. The problem is I deleted all widgets and I have checked both folders and I see nothing.
Take a look in this thread...
http://discussions.apple.com/message.jspa?messageID=741255#741255
It may be that since the permissions instructions are stored in the HintFile and just tell DiskUtility to leave them as they are, the widget files don't actually need to be there for the messages to show. -
I have a Macbook Pro that was slowing down. The HD was nearly full as I do a video work. I removed over 400gb of photos and video and it made no difference. I ran disk inventory x and that says that there is only 60gb on the hard drive but disk utility says there is still 430gb on the HD. How do I remove what DU says is still there.
ThanksYou may notice a difference in available space statistics between Disk Utility, Finder, and Get Info inspectors. This is expected and can be safely ignored. The Finder displays the available space on the disk without accounting for the local snapshots, because local snapshots will surrender their disk space if needed.

Hard drive is missing. I can boot from the cd but when running the disk utility, no hard drive shows up.
This is a problem that suddenly appeared.Please post a screenshot of Disk Utility that shows what you mean. Be careful not to include any private information.

Disk Utility says everything's fine, but Install disk doesn't find my internal drive as a possible destination. When I startup with Command + S, I get a looping "cannot mount errno = 19" message.
Problem started when I used Tech Tool Pro 6 to "de-fragment volume". Had to cancel that process before it finished because I ran out of time. Thereafter, when I startup my machine normally, I get the gray Apple logo at first, but it changes to a prohibited symbol (circle with a slash thru it) and hangs.
When I startup holding the Option key, I can see my internal drive, but I get the same results as above.
When I startup using the MacBook OSX Install DVD, it does not find my internal drive as possible destination.
When I startup using the MacBook OSX Install DVD and then run Disk Utility, it finds my drive, allows me to "repair" and says everything is fine.
When I startup with Command + S, I get a looping error message "errno = 19" and cannot stop it to do anything else.
When I startup from Disk Warrior v4.4, it does not find my internal drive to do any repairs.
When I startup from Tech Tool Pro 6 and run the "computer check" diagnostics, everything passes but the Volume Structure, which fails at "Volume Extents (B-tree)." When I use TTP's "Tools" option to run "volume repair" it will show my internal drive and allow me to click the GO button, but nothing happens and nothing changes.
I have a Time Machine backup on an external USB drive, but for as long as the internal drive doesn't mount, I can't use the backup to restore.It's a false report and should be ignored.
I would not rely on TT as I've already said earlier even before Grant posted similar advice.
I really think the Rigid Disk Block may be corrupted. This holds the partition map and could prevent a volume from being unmounted. Unfortunately, there is no way to fix that without repartitioning the drive which will remove everything. So, before going down this road I hope you have backups or can make a backup.
Drive Partition and Format
1. Boot from your Snow Leopard 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 Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Proceed with reinstalling OS X.
5. Download and install Mac OS X 10.6.8 Update Combo v1.1. -
My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?
Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
Quit and you should be able to install OS X now with your Apple ID and password.

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.

Please help me, I have a mid 2010 Mac book pro with a toshiba mk3266gsxf harddrive. It started making a clicking noise and then my computer crashed. I proceeded to boot in safe mode, but it doesn't work. When I ran disk utility in recovery mode, it showed no problem with my disk. Does any one know what the problem is?
Sounds like a mechanical problem with the drive and it ruined the sectors where the Macintosh HD partition (and OS X, and files and programs) reside, but not your Recovery HD partition.
If you held command option r while booting, that's Internet Recovery and it's loaded via the Internet, not via the Recovery HD partition on the boot drive, so that could mean the drive is dead mechanically or there is another issue.
In either case the drive will likely have to be replaced, it's a matter of what occured to where and the drive state if you can recover data or not. If you made recent backups then your fine.
My computer is not working, is my personal data lost?

Disk Utility says "no options" when I try to partition
Hi,
I have a flat-screen IMac G4. I want to partition the hard drive. When I open disk utility and click on the drive I want to partition, I get the partition tab, but everything is grayed out and it says "no options." Can anyone tell me how to proceed to partition? I want to restore another, smaller hard drive on the IMac, hopefully without erasing everything. This would be sort of an archive of the hard drive that's already on the IMac. It's old stuff that is not currently in use.
Any help is appreciated!
ThanksYou have to boot using your install disc. See http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh14.html
You posted in the OS 9 forum. You should post in the iMac or Tiger 10.4 forum. See http://discussions.apple.com/index.jspa?categoryID=1

Hi, how do I manage storage? Disk Utility says “other” is taking up most of my storage but I don’t know where to find “other". Please help!
For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside a photo or iTunes library will corrupt the library. Changes to such a library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper 2>&-
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective 2>&-
Launch the built-in 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 and start typing the name.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal. -
External hard drives UNMOUNT when verifying with disk utility
I have two external Lacie hard drives attached to my iMac. One is just for general backup purposes. The other is for Time Machine.
Today when I got home, for some reason the Time Machine drive was not appearing on my desktop. I rebooted the computer, the Time Machine drive reappeared, I ran a back up, everything seemed to be working fine.
To make sure the disk was ok - I ran disk utility. When I selected "verify drive" from disk utility - the disk suddenly UNMOUNTED itself, at the point of cataloging the hard drive, and the verification process stalled. What was originally a 1 minute verification suddenly changed to a 17 minute, then a 33 minute, etc.
I tried booting up in recovery mode (Command -R at startup) and the same thing happened. Are the drives going bad?Actually - I think when disk utility verifies the disk - disk utility itself actually "unmounts" the disk during the verification process. Probably so the disk cannot be accessed by anything else but disk utility.
I feel sort of silly, because what I thought was "stalling" was really just the disk utility going through its proper verification of the catalog file, multi-linked file, directories, etc. -
os x could not be installed on Mac book pro because storage system verify or repair failed.
When i open disk utility HDD does not let me repair.In order to repair the system disk you must boot from another disk drive. The operating system will not allow the disk drive it is running from to be repaired.
Book the MBP and create a bootable clone on an external disk drive. Then boot from the external disk drive and repair the system disk drive from there. -
I want to instal the beta version of Yosemite on a partition, but when I open Disk Utility to do so, it won't allow me. After pressing the plus sign at the bottom of the screen I can not enter a value for the size. When I look down at the very bottom I read the following:
Capacity: 3.12TB
Available: 115KB
Used: 3.12TB
My trash is empty and Finder says I have 1TB in free space available, so what's going on?
Perhaps related, my computer has been unreasonably slow (which is why I want to take the Beta for spin). I'm thinking there might be a connection. Is there a way to clear the detailed space so that Disk Utility will recognize it? In an attempt to speed things up I just reinstalled Maverick but nothing happened. I still can't partition and my computer is still slow.
