Disk Utility - repeated need for minor header volume repair...

Hi...
Three times in the last week and a half, Disk Utility has reported "Volume header needs minor repair". Each time, I've dutifully started up from my Tiger install CD, and successfully repaired the problem. On at least one of the three occasions, I also ran Disk Warrior and rebuilt the disk directory. Today, the same volume header problem is being reported again.
I've had similar minor disk problems in past, but the repairs always 'stuck' for some while. I'm thinking it's time for an archive and install (at least), but I'm wondering if others have run into the same problem and found alternate remedies.
I routinely run Onyx for maintenance and cleaning, by the way.
Is there anything else I might try before the archive and install? And/or is a complete reformat in order instead?
Data is backed up as of yesterday.
Thanks for any/all suggestions.
Peter B.

Allan... thanks.
When running Disk First Aid repair via Disk Utility when booted from your Tiger install disc, is anything reported as being successfully repaired?
If I recall correctly, yes... the specific volume header.
I typically re-verify when I boot back to my startup drive, and initially get passing verifications... then (only recently) within days (sometimes hours) the header problem is reported again.
I don't normally check in with Disk Utility more than (about) once a week... but since the problem has recurred, I am of course checking more often.
I have never had this recurring problem before. Reports from Disk Utility have been almost always 'in the green' - i.e. successful verification.

Lost disk image in Finder (Desktop) for backup disk on Intel Mac Pro OS 10.7.3. Time Machine cannot find the internal backup disk. The volume is grayed out in Disk Utility, though it CAN verify the volume. How do I get it back on my desktop?

First, restart the Time Capsule by disconnecting the power adapter and reconnecting it. If other devices on the network can see it, you can skip this step.

How can I find out which version of Airport Utility is needed for my Airport Express A1084????

I have this issue, too. The problem with the advice from Saito_Chickara is that Mavericks (I'm on 10.9.2) does not allow you to run AirPort Utility 5.x. So for those of us on Mavericks, what can we do? I have yet to find a solution. This is really frustrating.

How much external disk space is needed for editing HD video?

If I'm using FCE:
1) How much external disk space is needed for editing HD video:
if I downloaded 150mins of HD video? and
do editing with it which will have an output of 120mins.
Now PC, going to a MAC user soon Windows XP

Hi(bonjour)!
As a rule of thumb for HDV editing, use those numbers:
12 to 15 meg/second for capturing ( your project is 150 minutes long, so 780 meg/minute, or 117 to 125 Gig).
If you do any editing, add transition, video effect, add 12 to 15 meg /second to the total.
As your project will have to be rendered for the print to tape operation, calculate 12 to 15 meg/second for all the length of your final movie. Add this amount to the total. (example: a 60 minutes movie : 49 Gig).
If you want to burn a DVD on your Mac, calculate 3 to 4 meg/second for downconversion to DV material if you check "self-contained" in quicktime export dialog. (example: your finished project is 60 minutes long : 10.8 Gig)
iDVD itself needs 3 to 4 times this amount if you want flawless operation.
Finally, if you use your internal hard disk for all this storage (it's not a good idea to capture on the same drive where Mac OS X belongs), your Mac OS needs some spare room to breath (doing caching, etc), and your hard drive must have a least 25% of free space to avoid file's fragmentation.
As hard drive's price drop, get the maximum size you can afford. 250 Gig is a good choice if you want to do just one project of 90 to 150 minutes at the time.

It sounds like your hard drive either has a software problem that Disk Utility cannot fix or that the HD has failed (mechanically).
Your Mac may have booted either to your recovery partition or to internet recovery in an attempt to repair the drive- I can't tell from your post.
I'll assume that it was the recovery partition.
Try to boot into internet recovery (hold down option command R at restart), and see if you can repair your HD with Disk Utility. You should also repair permissions while you're there.
If that doesn't work, try to boot into single user mode (restart, hold down ⌘S until you see a black screen with white text) and repair your hard drive. Here's a reference with directions: Repair Your Hard Disk in Single User Mode | Everything Macintosh
If that doesn't work you have a few options:
If your mac originally came with installation disks, you can try to boot from the installation disk and then see if you can repair the HD.
There is a small chance that Techtool Pro 7 will be able to repair your HD if Disk Utility can't.
If none of that works then your HD has probably failed and will need to be replaced, which is not too difficult to do yourself if you can use a screwdriver.

Hi. My mavericks is crashed and when i on my mac always showstha disk utility window. I do everything like repair and all but not fix this problem. I have no back up of my files. Is there any way to reinstall mavericks without erase my old data ?

To back up your data, either use Target Disk Mode and a cable from another Mac (which mounts your problem Mac as an external disk of the other Mac) and Disk Utility on that other Mac, or — and this is all assuming you either have a slow Internet connection and don't want to use Internet Recovery, or if you have an older Mac that doesn't support Internet Recovery — you can create a bootable USB key disk on another Mac and then boot your problematic Mac from that keydisk, then use Disk Utility from the installer to make a backup to another (external) (scratch) disk. You can also use that keydisk to reinstall OS X, to repair or to reinstall OS X.

Boot Camp and Disk Utility giving Error for my Hard Drive Volume

When trying to partition my Hard Drive with Boot Camp, I get an error message after a while saying that it can't be partitioned because there is an error in the volume and that I should check it in Disk Utility. After running Verify Disk, it had told me that the file count was wrong and that I should repair my Disk. I have leopard installed, but only had access to a Tiger Install Disc, so after booting to that and apparently repairing successfully, I booted back onto my Hard Drive and ran Disk Utility's Verify Disk again. Now it said that my Volume Header needs minor repair. I still get the same message in Boot Camp. Running Verify and Repair Disk from the Tiger Install Disc tells me that everything is alright and the Hard Drive doesn' need repairing. I read on an Apple article that verifying a disk that's booted can produce inaccurate results, and that it shouldn't be worried about, but I can't install Windows because of this! What should I do?

Hi,
you have to boot from the Leopard OSX DVD in order to repair the Leopard OSX volume on your harddisk.
Using Disk Utility from an OSX version that is prior to the one you want to repair can indeed cause more errors than before.
So, search for the Leopard DVD.

Disk Utility formats Hard Drives as Logical Volume Group

I just replaced a hard drive which had died in my Mac Pro which has OS X 10.9.5. To format the new 3TB hard drive I went to Disk Utility. I used "Erase" in its fastest form and the drive was formatted with the Type: Logical Volume Group.
I remember this was a problem a few years ago when I first put hard drives in this computer. I think it was considered a bug in the Disk Utility in OS X 10.8 that it would automatically format drives greater than 2 TB as Logical Volume Group. The solution for me was to restart the computer with my OS X 10.6 disk and use the Disk Utility in that to reformat the drive. I never really understood why Logical Volume Group was a problem but I just obeyed what the wise ones of the Internet had to say.
So, now I am wondering if I should reformat my new Hard Drive as GUID using my OS X 10.6 optical disk again? If it was a bug in the Disk Utility of OS X 10.8 then why is it not fixed in the Disk Utility of OS X 10.9? Is there an actual problem with having disks format formatted as Logical Volume Group? Is this now just Apple's way of doing things?
Thank you.

You could do your reformat using your 10.6 DVD. That's a decision that's up to you.
Not every bug in a previous OS gets fixed in a new OS.
I don't believe CoreStorage (Logical Volume Group) causes any sort of issues. Whenever one encrypts their Macintosh HD, the format is converted to CoreStorage. Fusion Drives are using CoreStorage and now Yosemite converts portables (laptops) to CoreStorage during the install process. As far as Yosemite is concerned, Apple seems to have gone the route of CoreStorage for portables. Even during the Setup on a portable, FileVault is offered with the default of YES being checked. So, if a customer isn't paying attention and continues with the install, they could encrypt their drive without knowing to uncheck the default checkbox.
Thank you for your reply.
I have decided to reformat my new hard drive using my 10.6 disk. I like being able to split it up into more than one volume if need be.
I understand that not every bug in a previous OS gets fixed, but this strikes me as being really a very large bug, so I think it would be good if Apple addressed it.
It is useful to know about Yosemite's behaviour. When I upgrade to Yosemite I will be a bit more prepared. In fact my MacBook Pro has FileVault on with Mavericks so Yosemite won't change anything there.

Disk utility & TechTool Pro will not recognize volumes on hard drive

My Powerbook G4 will not start up. This is what happens:
1. Startup chime
2. Hard drive starts to make a constant 'pause-click, pause-click' like a skipping vinyl record sound
3. Then I only get as far as the flashing question mark on screen
I have disconnected all peripherals. I have booted up from install CD and used *Disk Utility* and it does not recognize the hard drive, only the CDR drive. I have booted from the Apple Hardware Test CD. All hardware passes. I have booted off the *TechTool Pro CD* and tried to run the entire suite of diagnositc tests. All hardware passes, all drives pass, but when I get to Volumes and Files, none are recognized. I have tried to get to the *Startup Manager*, but I can't get to that point either, only as far as the flashing question mark. I would like to be able to salvage data from the harddrive, so haven't tried to reinstall software and OS.
It seems to me that the hard drive is probably dead and I probably need to replace it, but is there any hope to recover data from the old hard drive
Any suggestions on what else I might try or on confirming my tentative diagnosis, would be greatly appreciated. Thanks

Thanks for the quick reply Tom,
I mostly save my work related documents on external flash drives or zip drive media, so my most important data for the most part is backed up. However, I had gotten a bit unattentive with personal interest stuff, like photos, music etc. I'll probably think of something important months from now and realize it was only on that drive, but for now I am most concerned about my downloaded emails and email addressbook. I never thought to back those up. Makes me want to stop running Thunderbird and keep all my emails online. Anyway I have some recent business inquiry emails from new contacts that are stuck on that drive. Can't recall the exact name of the organization this person was with. Aghh.
Think there is any use trying one of those data recovery programs to see if I could extract some information from the disk?
I am realizing that I will probably need a new hard drive to get the computer running . A friend's dad who is a computer teacher (though mostly PC but has kids with Macs so he's been working with Macs a bit and learning) mentioned the possibility of putting in a new hard drive as the start up drive then installing the old one as a secondary hard drive so I can try to access my data that way. Think that sounds like a feasible option to try? Perhaps I could run the recovery within that configuration. Worth a try? Pointless?
I appreciate any words of wisdom or commiseration.
Thanks,

RAID card or Disk Utility RAID - Need simple comparison please.

Folks, I am trying to make sense of the necessity or lack thereof for Apple's RAID card. Can someone provide a simple breakdown or comparison of the RAID card and/or loading the Mac Pro with drives and striping them using Disk Utility. I was under the impression that I could buy a Mac Pro, fill up the drive slots and just have Disk Utility set up the RAID. I'll be working with HD.
Enlighten me please

Can someone provide a simple breakdown or comparison of the RAID card and/or loading the Mac Pro with drives and striping them using Disk Utility.
Users that are working with uncompressed HD 1920x1080 10bit RGB video usually aim for storage speeds of 240MB/sec or more. Obtaining this level of performance across the RAID is the trick.
The Apple RAID 5 card can provide 306MB/sec. when configured as a striped RAID set, using four Seagate 250GB model 7200.10 internal hard drives with 16MB cache, when the volume is empty. By the time the striped RAID set reaches 80% full performance drops to 214MB/sec. A setup that can provide 240MB/sec. when the volume is 100% full will provide a more reliable configuration for 1080 uncompressed HD video processing.
Disk Utility can provide this same level of performance without the RAID 5 card.
So what is the advantage of the Apple RAID 5 card?
The redundancy of RAID 5 can add a layer of protection against the failure of a single hard drive. RAID 5 can be rebuilt whereas RAID 0 provides zero data protection. The problem with RAID 5 in a four drive setup is that one disk is required for storing parity data. This leaves the RAID 5 slower as only 3 disks can be used for performance. In a RAID 5 four drive setup the top speed available will usually be approximately 210MB/sec. and when full closer to 180MB/sec. As you can see RAID 5 adds some data protection but the price is lower performance. That is the feature that the Apple RAID 5 card offers combined with a bootable internal solution.
Do I need 240MB/sec. performance?
Users that are not working with uncompressed HD 1920x1080 10bit video may find slower RAID performance will work for them. HDV requires approx. 25MB/sec and DVCPRO HD needs 100MB/sec.
On the other hand, when I am working with large video files the faster the RAID, the easier it is to work with large files. So while I may not have dropped frames with slower DV formats I still
prefer to work with as fast of a RAID configuration as I can justify.
Other Options?
The Mac Pro has many superior performance options available for creating fast RAID volumes. My current favorite setup is the eight channel Areca ARC-1221x RAID 6 controller paired with an external Enhance E8-ML enclosure. You can see an AMUG review of it here:
http://www.amug.org/amug-web/html/amug/reviews/articles/areca/1221x/
This setup provides a RAID 6 array with twice the redundancy of RAID 5. It also supports up to eight hard drives which significantly enhances performance. Using eight Seagate 320GB model 7200.10 hard drives in a RAID 6 configuration with the ARC-1221x provides over 430MB/sec. when empty and over 220MB/sec when 100% full. Up to two drives can fail and the RAID can still be rebuilt. The ARC-1221x is available to AMUG members for $680 until the end of the month here:
http://www.tekramonline.com/amugpromos.html
The Enhance E8-ML 8 bay enclosure is $595. Details are here:
http://www.amug.org/amug-web/html/amug/reviews/articles/enhance/e8/
You will also need two external Mini-SAS to Infiniband cable model Ext-MS-1MSB. I got mine here:
http://www.amazon.com/exec/obidos/ASIN/B000FUOMO0/arizomacinusergr
So for $1340 you get an 8 bay RAID 6 setup that provides awesome performance, supports RAID levels 0, 1, 3, 5, 6, 10 or JBOD and can even be setup to boot the Mac Pro with any of these RAID configurations. I think this is a great setup.
More Options
If the user already has SATA PM enclosures and wants to add external RAID 5 capability for minimal cost, HighPoint has introduced the new RocketRAID 2314.
http://www.amug.org/amug-web/html/amug/reviews/articles/highpoint/2314/
The HighPoint RocketRAID 2314 only costs $200 but it adds nice RAID 5 performance with SATA PM enclosures when using the new Mac version 2.11 driver. Using two SATA PM enclosures with 5 hard drives mounted in each enclosure for a total of 10 drives can provide RAID 5 performance of over 370MB/sec when empty and over 318MB/sec when 100% full. It doesn't offer RAID 6 or boot capability but this is very nice RAID 5 setup.
The card costs $180 on sale here:
http://www.amazon.com/exec/obidos/ASIN/B000NAXGIU/arizomacinusergr
Two quiet Sonnet 500P five bay enclosures will run $1000
http://www.amug.org/amug-web/html/amug/reviews/articles/sonnet/500p/
So for $1180 users have a high performance RAID 5 setup that supports up to ten SATA hard drives. The RAID 5 performance is twice as powerful as an internal four bay solution. Plus, this setup allows users to still utilize the Mac Pro internal bays for importing more data or for backup.
The Apple RAID 5 solution is a nice one. It just seems a little pricey compared to other faster solutions that are available. However, if Apple ever came out with a new RAID 6 card that used the internal 4 ports plus offered two external mini-SAS ports for a total of 12 drives, that would be a product totally worthy of a $1000 premium.
Happy hunting!

Disk utility and reformatting for an external portable hard drive

I bought a brand-new iomega ego portable hard drive (USB compatible). When attempting to format it, I went to 'disk utility' to erase the drive. The drive appears, with the following information listed: Mount Point : /Volumes/Iomega HDD Capacity : 465.8 GB (500,105,217,024 Bytes)
Format : Winows NT Filesystem Available : 465.7 GB (500,022,378,496 Bytes)
Permissions Enabled : Yes Used : 79.0 MB (82,838,016 Bytes)
Number of Folders : 0 Number of Files : 32
Obviously, it needs to be reformatted. But when I click the erase tab, it will not allow me to pick the volume format or name (it just has it listed but unselectable).
Any suggestions on using disk utility or reformatting the drive so I can use it will be useful!

The drive has been pre-formatted for NTFS. You need to do the following:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to APM then click on the OK button. Click on the Partition button and wait the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

Is Disk Utility "shrinking partition" for a week doing a defrag?

And can I ever stop it, or will partition self destruct?
Summary:
2TB Partition, containing 1600-1700 GB (maybe 350GB free)
Attempted to Resize partion to 1.99TB (reducing size only 10GB) using DU GUI
Assumed it would take just a little while to move [up to] 10GB data into free space.
That was a week ago! External 2TB drive on USB2, activity light flashing big time, random, misc short pauses (no patterns so looks like it's really working) 24/7 ever since. Disk Utility says "Shrinking volume" with status bar about 60% complete and not moving since soon after beginning the process.
This archive wasn't backed up (stupid, I know). So I bought another drive to do that with, but wanted to do a block copy to save time and to do that the program needed the source volume to be a tiny bit smaller in order to fit my destination. (Stupid again, for the attempt before it was backed up. I should have just done a simple copy!) Yes, I've been kicking myself for a week now.
Some programs that do nondestructive volume or "filesystem" shrinking will do a complete defrag in the the process I believe. Is that what's happening here? Anybody know for sure? Can it really take this long with maybe 340GB free to work with? I can't think of anything besides defraging that could explain this behavior. Seems unlikely but could indexing be kicking in? How many more days/weeks/months might I have to wait? I really need this to be over.
If I stopped it, I wouldn't mind losing any one file (or a few), I just don't want to risk losing it all. The Drive is an archive of mostly media files. Many large files exist from 1.5GB to maybe 5GB, with few up to maybe 18 GB. Lots of small files too. All are rarely accessed and never edited (re-written) so I would guess there's not much cause for fragmentation.
Now to make matters worse, I use this computer for other things, and 3 days into the shrink, most of the computer froze. Mouse moves but nothing is clickable. Clock stopped updating. Can't bring up Force Quit. At day 5 I tried again and noticed the dock would appear and magnify, until it froze too. Drive still seems to be working with activity so I presume the shrink process is still alive. I don't know if it will survive to completion however. How bad would things be if I just powered it off????? Any other solution besides just wait for an unknown length of time?
Thank you for any help, and for not kicking me again while I'm down.
Mac Mini (Late 2009) 2.24Ghz, 4GB, 10.6.5

UPDATE: After more than three weeks of continuous disk activity, power to the external drive was accidentally turned off. After rebooting the Mac and connecting the drive, all data seemed to be there, and was readable, and the drive was writable. I attempted to back up the whole drive at once with a Finder copy (no OS on this drive) but it failed partway through. A group of files copied with zero data, which I presume happened at the failure point with an incomplete write operation. A piecemeal copy worked however, and all data was backed up intact I believe. My guess is that some corrupted file caused all the problems (never located though), but it could have been a hard drive issue too. If I learn more I'll do one more update. But the point is, that simply stopping this failed shrinking process midstream did NOT destroy the partition or volume info, FWIW, although everywhere I looked on the web this prospect appeared very gloomy. Bottom line, shrinking a partition of data without a backup is still a very risky prospect, and I will certainly never attempt it again. I consider myself extremely fortunate that I did not lose it all, or even any! OTOH, stopping a shrink is not guaranteed to have the dire consequences that one would suspect. More testing would be necessary.

Disk Utility erase tab for hard disk is missing after accidental OS deletion when installing Win 8.1 (BootCamp)

Hi there everyone,
This is my first post and I hope I can get this issue resolved with your help .
So the issue that I am having is that my Disk Utility is not showing giving me the option to reformat my entire hard drive.
The reason I want to this is because my Boot Camp Assistant won't partition my drive. This error comes up:
So after looking through the internet and forums i couldn't resolve this Boot Camp issue. So I decided to try and just wipe out my whole disk but as you can see I am unable to do that.
Prior to this issue, I had tried to download Windows 8.1 using a bootable USB stick and have accidentally deleted my Macintosh HD partition from the Windows install menu by opening up a terminal (fn+option+F10 was the key used to open up this terminal if I remember correctly). I was pretty upset about that, thankfully I have a backup around. Not knowing what to do I proceeded to installing Windows 8.1 anyway. Half way through the installation there was an error which I did not record. I simply exited the installer and proceeded to the Recovery System start up menu and it installed a version of OS X Lion from the internet. Then I installed Yosemite thinking everything is OK.
I decided to try to install Windows 7 now and the issue mentioned at the beginning ensued. Previously there was a disk0s1 and disk0s2 that can be seen from the Disk Utility but I could delete one of them. The other one I could only erase but could not delete the partition itself. From terminal i determined these two partitions were from the previous Windows installation attempt. The size was relatively small for both.
I ran a disk repair for the Macintosh HD volume and this error pops up:
