Unable to reinstall OS X or use Disk Utility on e-Mac; unusual problems

Thank you for any ideas on this!
Try to run Disk Utility but it claims it loses contact with Disk Management Tool and stops in the middle. Tried three different sets of disks and an external CD drive. Have never successfully been able to use DU on this machine.
After successfully reinstalling OSX disk 1, computer restarts to the desktop rather than asking for disk 2.
THE DATE AND TIME WILL NOT STAY ACCURATE. Jumps all over the place.
Tried buying new PRAM battery on the advice of my Mac guru friend. Ran Hardware disk and everything checks out.
Any ideas? Friend suggests a grenade.

Jeff and all,
My Mac guru deciphered all the techie info down to the following to fix this problem, and it WORKED!!!! Yippee! Only took 7 hours before I figured out how to find this list.
My 82-year-old mother can do without iTunes.
1) Move iTunes onto the Desktop.
2) Run Disk Utility
3) Go to HD>Library>Receipts and trash all iTunes.pkg files EXCEPT for iTunesX.pkg and iTunesPhoneDriver.pkg
4) empty Trash.
5) move iTune from Desktop back to 'Applications'.
6) Put Chess in the trash.
7) Empty the Trash
THANK YOU!

Had to repair the HD using Disk Utility every few weeks- Big problem?

Hey guys,
I've used Onyx to verify my HD & it said that I needed to repair it. So I restarted using the Leopard CPU Drop-in DVD & it's been saying "Invalid file count" & "Invalid volume directory count" but it gets fixed. It seems like this happens around every few weeks. Is this a big problem? Anything I can do to prevent it?
Thanks,
David

Hello David
Yes they are replaceable but it's not straightforward. On the newest models it's easier/simpler to get into them but on the older models you needed a palette/putty knife and a good technique simply to get the top housing off. Inside there are a few small/thin/delicate connecting cables you need to be careful of. These two sites should give you more of an idea?

If this seems like too much hard work take it to your nearest Apple Repair Specialist or Genius Bar. They'll be happy to do it for you for a nominal fee. You get the best of both worlds then - peace of mind the job has been done expertly and a replaced hard drive with all your data transferred over.

External hard drive not recognised after using disk utility to format

i formatted two external hard drives using disk utility on my mac mini, now they do not show in finder. they can be seen in disk utility but the repair options etc are greyed out?

HT3275 I continue to get the following error message: Unable to complete back up.an error occurred while creating backup folder. It's a brand new drive. When I attempt to repair it using disk utility I get:unable to repair disk cannot unmounted

I have been trying to use time machine on a new lacie 2tb usb 2 drive for back up. I continue to get: "unable to complete backup.An error occured while creating backup folder". When I use disk utility to repair I get another error message: unable to repair disk unmountable.
Help me Obie One Canobie you are my last hope

I have confused myself with the facts! Started out keeping track of every step and every variable but have sort of lost it as we progress here. First I quit all applications then swapped connections between mouse port and backup disk port to influence possible bad connections question. Changed power outlet receptacle for the backup disk. Disabled the put-the-HD-to-sleep option. Then powered down the computerator.
Next started up computerator. Turned Time Machine ON and experienced multiple successful backups! Then I started up a few applications, Mail and Text Edit (but not Safari so far). Had a few more successes. After each backup, I used Disk Utility to verify the backup disk is still OK. This because the error about unable to unmount the backup disk seems to go hand in hand with Disk Utility finding the backup disk to be bad.
Put computer to sleep for the night. Upon starting up in the morning, and before doing anything else, I did a backup disk verification... BAD! Did a restart and verified the backup disk... OK.
Did a few Sleep-bad, Restart -OK repetitions.
It seems consistent: Sleeping the computer apparently messes up the backup disk but doing a Restart "repairs" it.
=============================
Now then, I don't understand everything I know here. Methinks that maybe keeping the HD from sleeping during lulls in activity has allowed successful backups through the day but manually putting everything to sleep for the night causes a return to the problem of spinning-back-up-too-slowly (which was explained earlier). Is there any truth in this?
I may abandon this Seagate thing for something more compatible. What's out there that we know works reliably for us?

Unable to initialize Thumb drive using Disk Utility!

Hi All,
I have a 4GB Sandisk thumb drive that works flawlessly till I tried to initialize it using Disk Utility in my MBP.
Now, whenever I try to connect the drive to USB port, system ask me to initialize the disk but when I try to initialize system goes into an unfinite loop of unmounting the disk.
And now when I try to format it using Windows, the message appears that "Unable to complete the format". The disk was working in both Windows and Mac prior to I used initialize function.
Any help would begreatly appreciated.
Thanks in advance.
-Ashish Sharma

Hi Samberl,
As I already wrote in my initial post that the drive was working before I try to intialize using MBP. Anyways, I already followed your advice and replaced the drive with a new one. But now I am worried if I again use it in my Mac and initialize using disk utility. As of now I have formatted it using Windows and using NTFS-3G in my MAC to read or write the data.
Anyways, thanks for helping

I download dmg files but cannot be open (not recognised). If I try try to use disk utility, it says the disk image unable to attach. Could someone pls help? Thnx

Hi, I am trying to install some programs (on mac book pro mac osx 10.6.8) that are downloaded in "dmg" file format. These are antivirus and security related programs. Unfortunately when I try to open the downloaded file, this does not open and I get message it is not recognised. I have also tried using Disk Utility but I get an error "unable to attach"l. This just started recently. I have downloaded the file several times but same problem recurs. Thanks for your help
PS: Other files directly downloaded from apple work fine.

curious to know your reservations about Kapersky!
They screwed up the first Flashback removal tool very badly, locking several users out of their accounts permanently. It took a day or so for them to react and post a revised tool, but the damage had been done.
They are one of several formerly PC only vendors who rushed to the Mac front back in the spring after the Flashback scare. I would advise giving all of those folks time to prove they really understand OS X before installing it on any of my Macs. There are several others who have proven themselves.
Since you are running what I assume to be a fully up-to-date OS X 10.6.8 you are not vulnerable to any currently known malware capable of impacting OS X or other Mac software. That's no guarantee there won't be something new show up tomorrow, but the chances of any commercial anti-malware software catching it before Apple can react is pretty slim, IMHO.
Now if you are concerned about Windows malware, that's a different story.

What is the capacity of the flash drive?
You might also be able to reinstall Lion without a flash drive, by booting up the computer holding the Command + R keys, and choosing Reinstall OS X.

Unable to use Disk Utility to repair disk.

Hi all
I have been having some problems trying to transfer movies from computer to my iPod. Someone just suggested that I use Disk Utility to verify disk permissions, as well as the disk. I was able to verify disk permissions and repair them. Noticed the some had something to do with iTunes, so that might fix my problem with transferring movies to my iPod. I then tried to verify the disk, but I got the following error "Error: The underlying task reported failure on exit." Also this program shows that the following "Checking volume bitmap.
Volume Bit Map needs minor repair
Checking volume information.
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair"
The <Repair Disk> button is not darkened, but is grey, such that is not an option. Any other way to repair this disk.
Thanks
Michael

The startup drive can only be repaired from another drive.
You have to boot from the install disk.
To do this: Insert the Install Disk 1 into the drive and then select Restart; when you hear the chime hold down C key until the apple logo appears.
This will take you to the installation software, but you do not want to install.
Select your language, then go up to the top menu bar to Utilities in 10.4 and navigate to the Disk Utility application.
Select the start up drive, then go to the First Aid pane where you can click on Repair Disk.
If it finds errors, repeat the process until it reports no errors.
After these repairs, quit the application, and restart normally.
Once restarted normally run Repair Permissions from the Disk Utility application found on your hard drive in Application/Utilities.

I recently downloaded is x mountain lion and while it finished it erased all my data, some of which I need. When using disk utility I found my old data but it says corrupted. I can't repair and while restoring the error code 32 Broken Pipe appears. Help?

My data I need is on my computer but it needs to be repaired but can't and when I try to restore it/back it up it ends abruptly with error code 32 broken pipe.
It was damaged while installing os x mountain lion and I found my data on disk repair (utility)

Sounds like your hard drive is badly corrupted, likely due to problems that were already there when you started trying to install Mountain Lion. The problem is, if you don't have any backups already, you may not be able to recover all your data from this state. Do you have backups of that data already?
If not, I assume when you say that "it needs to be repaired but can't," you mean that Disk Utility tells you there is a problem with the disk, but that it is unable to repair it? If so, you can try repairing the drive using DiskWarrior, which can repair problems that Disk Utility cannot. That may give you access to your data again, but may not.
Also, it's important to understand that if your data is not backed up, everything you do with the computer runs the risk of overwriting or corrupting that data. You may want to go straight to trying to recover your data. See Recovering deleted files.
Regarding the error code, if you're trying to back up the drive using Disk Utility's Restore tab, note that that is often not successful when the drive you're trying to back up is corrupt.
Once the situation is resolved - either because you have backups, are able to recover your data files or are forced to accept that they are gone permanently - you will need to erase the hard drive and reinstall the system and all your apps from scratch.

How do I use Disk Utility to help install Mountain Lion after many failed attempts?

I tried to install Mountain Lion from an App onto my MacBook.
First it said that my disk was damaged to i tried to repair it.
Didn't work.
Then it said I didn't have enough room to install Mountain Lion.
Then I tried to restore Lion.
Didn't work.
Then someone suggested I reset my PRAM.
Tried that, and now I am stuck.
I can't restore any of my backups from timeline.
I can't reinstall OSX because my drive is now locked.
And I don't know how to use Disk Utility to solve this problem!
Any suggestions welcome... I'm in way deeper than I understand and feel like anything I do is making this worse!

I gather that your computer is in a less than satisfactory state, so the process below will basically start you from scratch, but you shouldn't lose anything.
Okay, can you inspect the Time Machine Backups with the Finder? About two or so folders down you should start seeing your system files. Assuming all your files are present.
Important^
You probably have an installation disk that came with your macBook. Boot from that CD and install from the CD.
Run the verify disk utilites and repair utilities if necessary.
You may want to erase your disk from the CD's disk utility. This will erase your Hard Drive (make sure you do not erase your backups, as that would be very bad).
Once the installation is complete, run all system updates. Either look through your backup and find the Mountain lion installation app, or download it from the app store again.
Run the ML installtion app.
Once everything is up and running, move all files and folders you want from your TM backups and you should be good to go.

I need help with boot camp. "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."

This message appears every time I try to partition my disk:
"Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
I verified my Macintosh HD disk on Disk utility and then tried to repair it, but I am unable to click the repair button.
It says it's not available because the startup disk is selected.
I don't know what to do or how to go about both these problems.
Please, any suggestions?

Resized partition using Disk Utility and now Windows 7 will not boot

Hi,
Hopefully someone can help me!!
I had previously used Boot Camp to install Windows 7. However, I later realised I had not given myself anywhere near enough disk space as I started using Windows for things I hadn't originally planned on using it for.
Anyway, long story short, to solve the problem I uninstalled some applications on my Mac OSX and used Disk Utility to decrease the size of my Mac partition. My plan was then to reboot to Windows and use a Windows application to increase the size of the Windows partition. However - I coudln't even get that far.
Upon decreasing the size of my Mac partition (succesfully) I restarted my Mac in order to boot to Windows. However, I was greeted with a message along the lines of "unable to boot to Windows please insert boot disk and press any key" (I can't remember the exact message).
I was wondering if anyone knows of any way to restore my Windows partition, retaining all of my previously saved files on my Windows disk. It's probably a long shot, but the thought of losing everything I have been working on for the last few months is a sickening one.
What does give me a bit of hope is that, if I click Boot Camp it seems to recognise that Windows 7 is installed as the option that appears is to uninstall it.
Furthermore, if I view partitions in Disk Utility, a "DISK0S4" is listed. However, it's only at 20gb - if this WAS my BootCamp partition previously, it was originally at something around 60gb (I think - either way, definitely bigger than 20gb!).
On top of this, my current Macintosh HD parition is at 260gb and with the DISK0S4 partition at 20.21gb, there seems to be some space missing... I'm hoping this is the files I've been working on over the last few months!
Anyway, I've done some searching on the net and it *seems* that GPT fdisk *might* be my savour. I've downloaded it but have no idea how to use it and don't plan on playing about with it as I could no doubt do some real damage. If it is likely to solve my problem however, I'm certainly more than capable of being walked through what I need to do.
Please help!

Hi Christopher,
I also have problems with Windows rebooting after partition resize trying to reduce Mac side and increase Windows side. I do not see the BootCamp partition labelled as such while running disk utility. The Windows partition shows up when I boot up while pressing the ALT key. However, when I try to run Windows, it says " error loading operatig system".
I also followed instruction and went through to run gdisk successfully. Results towards the end.
What can be done? Windows still does not boot and It shows ? Suspicious MBR at sector 0.
Below is information based on typical questions you ask.

Error message using Disk Utility

Okay, my System Preferences is not showing up, so I ran the Disk Utility and this is the error message I got:
Volume Macintosh HD was corrupt and needs to be repaired.
Error: This disk needs to be repaired...then use Disk Utility to repair the disk.
What do I do? Do I reinstall Mac OS X Snow Leopard or is this a whole other issue? Do I take it in to get checked out? Can I fix this without taking it in? HELP!

What you need to do is repair the disk using your install disk (after you make sure that you've backed up your important data or have a current Time Machine backup):
insert install disk and hold down C key while restarting
once booted from the install disk, go past the languages, and then up to Menu bar - Utilities. Open Disk Utility and run repair disk. If it says "repaired", you're done. If not, run it again until you get the repaired dialog. You can then restart from your internal disk, eject the install CD and you're all set.
If Disk Utility can't repair it, you'd need a more powerful application or it could be other things - we'll wait with that until after you've run the repair function.

TS2570 Question re: "Start from your Mac OS X Install disc; use Disk Utility"

I've worked my way through the step-by-step trouble shooting in the TS2570 article up to "Start from your Mac OS X Install disc; use Disk Utility". So far, every step results in the same outcome - my formerly trusty 2007 Intel duo core iMac (24") will not start up, freezing on a grey screen with a blinking question mark on a folder. I don't completely understand this next step. I have both a Leopard and a Snow Leopard disc. I'm not positive whether these were for the iMac, or my old Macbook Pro. I assume this makes a difference.

Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
A flashing question mark or globe appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by one or more of these:
a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
b. Boot drive's directory has been corrupted - Repair with Disk Utility.
c. Critical system files are damaged or deleted - Reinstall OS X.
d. The disk drive is physically non-functional - Replace the hard drive.
Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.
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.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.
Reinstall Snow Leopard Without Erasing The drive
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.

Reinstalling Lion/Mountain Lion 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 Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.

I am having issues with USB 2.0 External Hardrives and my 15inch Retina MacBook Pro running OS 10.8.1. I was able to read write to the drives fine prior to using disk utility to erase and reformat the drives. Both drives show up in the side bar of Disk Utility, but fail to mount. Both drives Verify and Repair without issue, but still fail to mount. I have tried switching USB Ports, powering on/off, etc. I tried seeing them through terminal, but they do not show.
I first lost my Lacie 500GB HD when reformatting it with Disk Utility. I gave me an error message, but I can't remember what it said.
Thinking my drive died, I plugged in a McAlly external USB 2.0 500GB drive that originally worked fine, but then locked the entire computer completely, forcing a power button reset after 10 min of total freeze. Now that drive is unusable as well and fails to mount.
I am unable to Partition either drive because they will not mount.
Any help would be appreciated.
Thanks,
Chris

I called Apple Support after getting no usuable help through the Apple Forums. The rep felt is was a problem with the two older USB 2.0 drives compatablility with the Retina Macbook Pro's USB 3.0. He kindly offered to send me a Compatable USB 3.0 Drive, but could not offer a solution.
FYI, I tried using different cords and both USB 3.0 ports on my Retina MacBook Pro and both are self powered.
Thanks,
Chris
