PowerPC :: Disk Utility Indicated Unknown Error With HD
Jun 16, 2009
I have spent all day with a colleague wrestling with a 4 and 1/2 year old G5 tower that has been throwing up all sorts of cranky errors. (i.e. firefox crashes, flash crashes, programs wont load, itunes stops working, firewire drives make it insane). As part of the diagnostic flow, I attempted to verify permissions on the core HD. Disk utility only took a couple seconds to determine that there is some unknown error with the HD, and it cant continue. This leads me to believe that we are dealing with a flailing drive, which very well MAY be the root of the problems! Time to make an external clone onto a fresh HD, and see if that helps.
Install CCC 3. Open CCC 3, it hiccups on the dock, and then nothing. *roll eyes*. Install super duper. Run super duper. Now super duper refuses to let me make a bootable clone of the core HD? Fine, if that is how you want to play this game. I get two SATA enclosures. Put the suspect drive in one, and then a fresh drive in the other. Plug both into my MBP where i run a CCC bootable clone. Couple hours later, it is complete. Plug the new clone into the G5 tower, and it does not see it as a bootable drive. Okay, lets try the CCC clone again. Same result. I am desperate for options.

I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.
I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "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" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)

I'm running OSX 10.4.11 on a 12" PowerBook 1.5 GHz with 1.25 GB of RAM and an 80 GB HD.
When I run the disk Utility to Verify Disk, it ends with the message, "Error: The underlying task reported failure on exit." This happens if I run the Disk Utility from the hard drive, from the OSX installation disk or from an external hard drive.
The Repair Drive button is always grayed out no matter where I am running the disk Utility from, too.
So far, I haven't had any other unusual things with the operation, but I'm concerned that this could be an early warning of problems to come.
Has anyone else had this problem or have a clue?
I have cloned the entire hard drive onto an external drive with Carbon Copy Cloner. I know PPC systems won't boot from a USB drive, but I was considering booting from the install disk, re-formatting the drive from there and then re-installing from the external by running CCC from there. I hope someone will have a direct solution to repairing the drive without doing all of that.

I just got my computer yesterday and when running the "repair disk" function, I already get an error! Since I used migration assistant to move everything off my old mac to my new mac, I'm not interested in reinstalling the whole OS and transffering all my files again. This is a new computer, and shouldn't have this problem this early. I also get the same result when starting up in the recovery partition. How do I resolve this?

"Disk Utility has lost its connection with Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility".
I keep getting this error when trying to erase an external hard drive with Disk Utility. When I restart, the error appears again. I've seen others with this problem but haven't found a solution. I've tried removing iTunes from Applications and deleting select iTunes receipts.
I'm running OS 10.4.11

I clicked "Verify Disk" and i got that, the other two options worked. I read up on this on Apple's site but I am not having any other issues than the notice. I was told to run Disk Utility ever so often to keep my mac fast. I just happened to do it today and I got that. I am trying to avoid having to do ANY sort of reformat.. I don't have any means of backup. Like I said I am not having any other problems. I am able to restart and log in without any problems. Should I be worried about this since there is no other issues besides the notice itself?

I installed Ubuntu on my iMac, and it made 2 new partitions: DISK0S3 and Linux Swap. Here's what my disk utlity looks like: When I try to remove Linux Swap, it says that the partition (map is too small. When I try to remove DISK0S3, nothing happens and it keeps running forever before I press +Q to quit.

I am desperately trying to burn a ISO file to a USB and external HD but Disk Utility does not want to. Instead I get the error message "Could not validate source - error 254". So there must be a problem with the source which is the ISO file.
I already tried setting the Partition Map Scheme to both Master Boot Record and GUID Partition Table. I also formatted the drive to FAT and HFS+. I cannot find the cause of this error. It clearly looks like Disk Utility does not like burning ISOs to USBs or HDs.
However, I really really need to this since I cannot burn ISOs with my SuperDrive which is also a common problem [URL]with my MacBook Pro.

I just restore my Mac OS to a single partition and then I tried re-partitioning but it's giving me an error.
I've tried several times, tried using different sizes every time. My HD's capacity is 250GB, and I've got 108.95GB free. So I am sure that making a new partition of 35 - 40 GB is not a big deal. I also tried using Disk Utility, both from the Mac OS install disc and while using the Mac OS itself, but it keeps giving me this error. I do not want to format my Macintosh HD's partition because I don't have an external HDD on me at the moment so I will not be able to back up. I have a lot of important data that can not be deleted.

I am trying to format a SDHC card on my MBP. I am trying to create a recovery SDHC disk for my MBP.
The disk is a Transcend 16gb (class 10).
I formatted to Mac OS Extended (Journaled) w/ a GUID Partition Table but after this, Disk Utility is now showing only 10.38 gb of usable space, but finder is showing me the full amount (15.79 gb). When I look in finder there are NO files or folders on the drive.
I tested trying to put more than 10.38 gb worth of files on the disk and was told there was not enough space. If I format the disk to anything other than Journaled, I get the full 15.79 gb. Has anyone ever experienced this before?

I bought a 1TB Iomega Prestige drive, it worked great for a few months. Started making loud clicking sounds. Iomega sent me a replacement drive (refurbished).
I am using it as my time machine backup in Leopard, so it was really just a matter of plugging it in, formating it with the OSX file system and setting it up for time machine.
When attempting to format from Disk Utility, I get an error (see screenshot).
(Additional info: I can access it and format it without any problems from Windows 7 based PC).

After upgrading to 10.5.7, numerous permission errors highlight regularly in Disc Utility, which I run weekly (probably for too often). I never saw these with 10.5.6, or for that matter any earlier incarnation of the OS. I have also noticed progammes hanging more than before (especially Mail). I have run DiskWarrior and that didn't report anything untoward. Should I give up worrying about this and maybe join the Foreign Legion instead?

I have a G4 powerbook from around 2004 that was running slow so I tried updating the mac software since I hadnt done it in a while after downloading and installing the suggested items my computer has gone a lil crazy. First off i noticed my dock is completely missing and I've tried numerous things to fix it that were suggested to me but nothing has worked.
Next I attempted to do some restoring using disk utility that had also been suggested and it turns out disk utility wont even run I get the error message "You cannot open the aplication "disk utility" because it may be damaged or imcomplete". This message also appears when i attempt to open safari or itunes.
I am no longer able to find my restore discs so I dont have that option at the moment, any help would be greatly appreciated, I am about to go back to school to pursue another degree and not having to buy a new comp would be great news.
here are the items that were installed with the update:
2009-10-25 17:23:21 -0600: Installed "Java for Mac OS X 10.4, Release 7" (1.0)
2009-10-25 17:23:47 -0600: Installed "Migration and DVD/CD Sharing Update" (1.1)

Steps to reproduceOpen Disk Utility Drag an ISO image into the left sidebar Insert an USB Stick with enough space to contain the image Go to any restore tab in Disk Utility Drag the ISO file to the source Drag the Volume from the USB drive to the destination Check erase destination Hit restore
Results for me are (in any number of varieties to do this) either "Invalid argument" or in the log "Could not validate source - error 254".

I am trying to create a new image from a DVD and burn it to a new DVD using the MAC Disk Utility "New Image" option. The source DVD is 4 G and my target folder is on my external HD which has 298G.. plenty of space. However, whenever I attempt to SAVE the existing DVD to my external HD, I am getting the error message that the file is too large. I have tried the parameter for "Image Format" of both 'Read Only' and 'DVD/CD Master' and neither of them work. My "Encryption" setting is 'None'.

I can't seem to get my mac to start up, it won't get past the gray screen with the apple logo and spinning wheel. I have tried to use utility disk to fix the problem but it kept coming up with error- could not complete. It would also not see the hard drive in OSX 10.4 when trying to archive before re- installing. So we opened it in OS 9 which worked and we could see the hard drive. We restarted the mac in OS 9 in the hope that we could re- install OSX 10.4 from there. It will go right through the installation but comes up with error again when validating.

The last couple of days safari has been crashing pretty frequently for me. I've been using chrome no problem, but i do prefer safari, so I just googled it and got pointed to Repair Permissions in Disk Utility.
So I just opened Disk Utility, which I'm fairly sure I've never used before, and it's saying, under my HD "this drive has reported a fatal hardware error to Disk Utility. If the drive has not failed completely, back up as much data as you can and then replace it with a working drive."
It's saying it for both "FUJITSU MHZ2250BH FFS G1 Media" (I'm not even sure what that is) and "Macintosh HD".
There's nothing wrong with my computer? I've googled around and apparently this means my machines about to die?

I have a Lacie 1TB external drive. I'm trying to create another partition on it using Disk Utility so that I can use one of the partitions for Time Machine. When I go to add another partition, or even just resize the existing one, I get an error saying drive must be HPFS+ with Journaling enabled. It is. I've seen reference to this error in searches, but have not found a solution. Is there a fix for this, or another tool that I can use to re-partition my drive without wiping out existing partition? I have about 450GB worth of data on the drive that I might be able to store somewhere else temporarily, I would just prefer not to have to go through that....

I recently ran a ‘verify’ scan in Disk Utility as a precaution after Word crashed. An ‘incorrect number of file links’ error message showed up, as well as a prompt to repair this using Disk Utility from the Recovery HD. However, when I do a scan from the Recovery HD version of Disk Utility, no error messages or repair prompts appear.
My questions… Is this something to be concerned about? How can it be fixed? Would it be best to do a clean install of OSX? I only lost a little bit of data so I was pretty lucky.

Started G5, got a question mark. Rebooted from disk. Tried to repair. Told me it could not exit and complete repair to HD. Restarted again. This time everything in utility window red. Message is Fatal Hardware error to disk utility. Back-up if not completely failed and replace with new drive.
Not great at behind the scenes with my mac. Does this mean a shop visit. Any estimate on cost to me. Had lots of Macs. This is the first to crash and burn and its not that old.

Trying to re-install Twitter from the Mac App Store. When I click "install" I get a prompt to type in my Apple ID (pre-filled with jonas.clement@hotmail.com; NOT ME). When I type my correct Apple ID and password in I get an "Error -4" message followed by "Unknown Error" message.
I have NO clue who jonas.clement@hotmail.com is. My account has not been hacked (at least no unauthorized purchases have been made). When I view my previously purchased apps, I see the whole list, Twitter, included...but I can't seem to download it.
Here's what I'm running:
Mac OS X 10.6.8
App Store 1.0.2 (63.1)
Here's what I've tried. Signing out of the App Store and signing back in.Signing out of the App Store and not signing back in until I try to download the App. Signing out of iTunes (trying everything). Restarting. What else is causing these errors?

I have a dual 1.25 ghz MDD Powermac G4. It was working fine until a couple of days ago. It froze up, I restarted it. I got a blank blue screen.
Also, the computer made some awful clicky noises that I've never heard before.
I booted from the OS X installation CD. Disk utility lists the WD1800 hard drive, but I can't do a re-install and there's no option to repair it.
I can't erase or partition it because when I try, I get a failure message saying it can't be done ("chosen size not valid for chosen filesystem"). The HD is listed in system profiler... with a capacity of 0 bytes.
I assumed that the hard drive had died, so I went to a local PC shop and bought the only IDE drive they had (a Maxtor 6l250r0). I installed it, then booted from the OS X CD.
I know that new hard drives need to be formatted, but I assumed that this could be done with disk utility.
But disk utility can't find the new hard drive, doesn't list in the left column. It shows the optical drives and the install CD and the old WD hard drive which can't be erased or repaired, but no new hard drive.
It's not listed in the system profiler, either.
I checked the cable connections and tried installing it in the front carrier rather than the rear, but nothing works - disk utility and system profiler can't recognize it.
The only other desktop mac I have access to right now is my old 450 mhz Sawtooth G4. I tried putting the HD into the sawtooth and got the same results - disk utility and system profiler can't find the new HD at all, but has no trouble finding the old 20gb HD and the DVD and zip drives.
I'm... not really sure what to do here. Am I doing something wrong?

I meant to ask this a while ago, but just getting to it now. My powerbook makes this very weird nose that I find not only annoying, but concerning. Whenever I move my mouse around, it sounds like the HDD begins doing some action and it makes a noise similar to running disk utility. Also when I have the screen open and if I carry the powerbook, say for example of I want to hand it to someone or show them something, a medium to high pitched noise comes on again emanating from the HDD area. What the heck is going on?

I have been using a time capsule for about 2 years. I use it as an external wireless hard disk as well as a router for extending my wi-fi network (connection via ethernet).
For the last couple of days, Airport Utility has been showing two time capsules connected to it. One is "HVS Airport Time Capsule" and the other is "Yogender's Time Capsule". The second one does not belong to me. I have no clue who's time capsule this is. A screenshot is also attached here (one on the right does not belong to me).
Does it mean someone is hacking into my wi-fi and using that via their time capsule? I've changed the wi-fi password (for my time capsule's network and the original network) several times, but it still shows up.
This unknown time capsule also shows up in the finder under "Shared".
