Problem with "Prohibited name". Disk Utility can't repair the disk!

Hello,
Sorry if my english is not perfect, but I do my best!
I have a problem with almost all applications. When I quit an application, it appear the crashed window. I can submit to Apple support the report, but I don't because there is too much.
I start on a cd-rom and lauch Disk utility. It can't repair the disk because of two "prohibited name" lines in red. No more information!
What are the two "prohibited name"? File? Folder?
How to repair the disk?
Any idea?
Please, help me.
Thank.

Exactly which model Mac G5 is it?
What size is the Hard Drive, and how much space is available?
How much RAM is installed, and is it original or added?
What peripherals do you have connected? A keyboard, mouse, printer, external drive or modem, router, etc?
What happened between the last time the Mac functioned successfully, and when it didn't?
Have you made any changes, like upgrading the system, updated or installed any applications or programs, etc?
Have there been any unusual occurences, like freezes, crashes, power outages, etc?
See if you are able to perform the procedures posted below, and post the results.
THESE ARE THE STEPS FOR USING DISK UTILITY TO REPAIR YOUR HD
1.Insert the System Install disk, Mac OS X CD-ROM disk, or Restore DVD disk, then restart the computer while holding the C key. Use the System disk, of the OS, that is currently installed.
2.Once started up from CD or DVD, on the Menubar at the top of the screen, choose Disk Utility from the Installer contextual menu for Panther, or Utilities for Tiger.
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from disc to access Disk Utility.
3.Click the First Aid tab.
4.Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5.Select your Mac OS X volume, if necessary.
6.Click Repair. If DU reports errors it has fixed, re-run Repair Disk until no errors are reported.
7.Repeat steps 5 & 6, but select the Hard Drive this time. It's usually the first listed with the manufacturer's model number. Make note of the S.M.A.R.T. status.
8.When finished, select Quit Disk Utility from the Installer menu.
9.Select Quit Installer from the Installer menu.
10.In the resulting pop-up window, choose restart.
11.After the computer has restarted, you can eject the CD.
TO REPAIR PERMISSIONS ON THE STARTUP DISK
1.Open Disk Utility, located in Applications/Utilities, and select the startup disk in the left column.
2.Click First Aid.
3.Click Verify Disk Permissions to test permissions or Repair Disk Permissions to test and repair permissions. (I never "Verify". Just run "Repair".)
When "Repair Permissions" is complete. Quit "Disk Utility".

On which Disk? Does the highlighted one have OSX on it?

Can I use the Disk Utility Application to backup bootcamp windows 7?

Can I use the Disk Utility Application to backup Bootcamp that has Windows 7 on it? If I install a new blank drive, I would like to know that using Time Machine I can get the MAC OS back and using the Disk Image Utility I can restore Bootcamp with Windows 7.

NO.
You have to use Windows or a Windows utility.
There are programs that will clone an entire drive (sector) as well.
DU does not though. Paragon does support Boot Camp.

External Hard Drive Disk Utility Can't Repair the Disk

Hi,
I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
Thanks
I have a Macbook PRO late 2011 running OS X Mavericks.

Use a more powerful utility such as DiskWarrior, or a product such as those listed here.

External Hard Disc won't mount - Partition Map error. Can't repair with Disk Utility

Happy New Year all and thanks in advance for any support/advise.
I have some important data on an external drive that does not seem to want to mount. The drive is a 500 GB Seagate connected via USB. I am currently on an iMac 3.06 GHz Intel Core 2 Duo running Yosemity 10.10.1
What I've tried:
Multiple computers - connected the drive to various apple computers with the same result.
New enclosure: I have removed the actual HD from the enclosure and connected it using a new one.
Disk Utility: Verifying Disc reports the following error: 'Error: Partition map check failed because no slices were found.' Screenshot below:
I have searched this and other forums and run a few commands in Terminal that seem relevant to the issue, but am out of my depth in terms of interpreting the results. Thank again for your attention!!!
Commands run in Terminal:
diskutil list
diskutil cs list
mount
diskutil info disk1

Select the disk1s1 volume under the main drive entry, then click on the Mount icon in the Disk Utility toolbar if it goes active and see if a volume then mounts on your Desktop. If it does not, then you need to reformat the drive. And, you cannot access the volume in order to copy your data somewhere else. If you are willing to spend money on the problem, then you can always try using a software recovery utility:
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as MAC Data Recovery, Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.

'Disk not recognised', can't repair in disk utility.

I have a Portable Hardrive im using for work and backup. It's relatively new, with one of those dual usb chords.
After using timemachine yesterday, I plugged it in today to find that not only could i not get to my files, but the repair button is disk utility was also unavailable. I tried Data Rescue, with no luck.
Any ideas? All i need off the disk is one 70mb folder.
Thanks.

Since Disk Utility still detects the drive, you could try using dd (➚) via Terminal and attempt to clone the volume. You should do this step before trying to do other recovery/diagnostic options; anytime you spin up a drive that may have hardware problems, you increase the chances that you're exacerbating the issue. This method obviously requires that you have enough free space on another volume to accommodate the size of the clone.

Re: kmosx: How to recover if you can't repair with Disk Utility

"This tip is ready for consideration."

I have never done it but it's possible that you have to create the .dmg using the startup disk?
You are trying to archive a running system - that may be the problem
Reboot with the Tiger disk (not Leopard) and use the DU on that disk.
See if that works.

IPOD won't connect to ITunes. Mac OS Can't repair the disc and Partition Failed. Help!!

Hello,
I am distraught because my IPod Classic won't connect to ITunes. My Mac won't even recognize it after a few seconds, and I have to keep resetting for the Mac to recognize it. Mac OS can't repair the disk, and said to reformat. I tried to partition, but that failed with the error message: couldn't unmount disc. I don't mind losing all the files, and am really just hoping that it will work again. I have virtually zero technical knowledge, and thought I might reach out to see if any savvy users know a trick or two that I might try.
Thanks for all your help,
Mary Louise

Try:
- iOS: Not responding or does not turn on
When it says place the iPod in recovery mode use one of these program
For PC
RecBoot: Easy Way to Put iPhone into Recovery Mode
If necessary:
Download QTMLClient.dll & iTunesMobileDevice.dll for RecBoot
and
RecBoot tip
For MAC or PC
The Firmware Umbrella - TinyUmbrella
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

HT2711 I used the "repair disk utility" to see why my computer is running slow but it gives me an error message saying, "disk utility can't repair this disk, and restore your backed up files. My computer was running slow and taking some time to load page

I haven't used my computer in a month, so when I turned it on, I saw it was running slow. The circle that is used to load the page kept coming up and it took sometime for things to load up. I tried to go Into safe mode, and it worked, but I know your limited on what you can do in that world. I also tried to repair the disk but it kept giving me an error message. How can I resolve this problem?

Time Machine is a back up you have to set up to back up before there is a problem like a hard drive failure.
It is possible to recover files from a failed drive, but it is an expensive proposition.
There is a faint hope that an app like Disk Warrior or TechTool Pro might repair the drive. You could try making an appointment at an Apple store and ask a technician there to take a look... the diagnosis will not cost you.

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. 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 the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

Some problems can indeed be fixed this way. But working from Recovery_HD or Disk Warrior DVDs and working in the restricted environment those provide can be difficult. You can literally spend days working on this problem (while your regular work is unavailable) only to discover the old drive is unsalvageable.
There is no way to know up front whether you are facing a major Hardware failure or a minor software glitch, or something in between. Often you are forced to work from the drive you no longer trust. I continue to recommend you do this work from a different, fully functioning Mac OS X booted from a different drive.
If you have had the foresight to (as The hatter often recommends) clone your virgin install onto another drive for use in such situations, you will be able to recover from such problems in record time. If not, my previous recommendations stands:
Buy a new Drive. Or two. Install Mac OS X from scratch on a new drive, and get your Mac running again. Later, you can use the full power of Mac OS X to attempt to rescue your data, if needed. Then Zero the old drive, to see if it can hold data again reliably.
If the old drive eventually provides some needed data, and is salvageable, Merry Christmas.

"Disk Utility can't repair this disk...and restore the backed up files"

Hello, my macbook crashed a few days a go as well and after going to the recovery drive and OX Utilities tried to verify and repair disk it gives me this error "Disk Utility can't repair this disk...and restore the backed up files" is the second time that occurs after replacing the hard drive for a new SSD, i thought my problem was solved and is not. Any Ideas? the only other thing i can think of is the logic board?

Backup your files and arrange for an appointment at an Apple store genius bar for a free evaluation.
Ciao.

My computer is shutting down before fully booting up. I am running the disk utilities program and have this message: Error: Disk Utility can't repair this disk . . . disk, and restore your backed-up files. Can anyone suggest what I should do next?

So, you can't Install OSX to the external?
Or you can't boot from it when you do?
You're not the only one wondering... I'm reminded of the Goose that laid the Golden Egg story.

Why I can't repair the disk in disk utility?
