Is Disk Utility 64-bit Native in Snow Leopard 10.6.5

I've got a 12-core Westmere MacPro with 16GB RAM running Snow Leopard 10.6.5.
I'm wondering if Disk Utility is 64-bit, and could therefore address more than 4GB RAM when running in 64-bit kernel.
I need to rebuild a corrupt directory of a 20TB RAID volume and the directory header is 6.5GB...
Thanks in advance,

Update:
Tried running Disk Utility in a 64-bit environment (12-core Westmere 16GB RAM) to no avail. Now reformatting RAID and starting backups up again.
Not sure I stated what the RAID was but will for archival purposes. 48TB (40TB Formatted) RAID5 Polaris 4GB Fiber Attached storage used for backing up an exact replica of an Avid Unity server's media (about 20TB of storage).
Looking forward to a 64-bit version of Disk Warrior!

Disk Utility won't run with Snow Leopard

I updated to Snow Leopard 10.6.2 and now when I run Disk Utility.app it says that it is version 11.1 and will not run. I'm not sure why this app didn't update at the same time. Where can I download 11.5 Disk Utility?
Thanks!

make sure you are running the correct copy of DU. you likely have two copies and are trying to run the one which is not in the default location. in finder go to main hard drive->applications->utilities. start DU from there. if that's not it pull DU from the SL install DVD using Pacifist http://www.charlessoft.com/

My macbook came with snow leopard, if I upgrade to Lion will I be able to use my restore disks in the future and if I do use my disks that brings me back to snow leopard, Will itunes remember I purchased Lion or will I have to purchase a second time ?

At this point, you can no longer download Lion (10.7) from the App Store, only Mountain Lion (10.8) - make sure all your applications are fully compatible if you decide to upgrade.
Yes, you can restore 10.6 using your restore disc should you wish to - and the App Store (not ITunes) will have a record of all your purchases, since it's linked to your AppleId.

Why after having installed mountain lion in hard disk using a MBP 17"mid 2010,isn't possible to install native original snow leopard in other hard disks using the same MBP?

Seems something is changed in the firmware that doesn't allow more to install snow leopard. Someone can help me?

In general, a 2010 model Mac should be able to re-install Snow Leopard. It would require a complete backup, a complete wipe, then install of Snow Leopard. Then be careful not to restore OS X Mt. Lion files over SL, when restoring your data files and applications.
What is the Mac Model Identifier in About This Mac/More Info/Hardware Overview?
Are you using the Restore disc that came with that model Mac? If not, you may need to purchase a retail Mac OS X Snow Leopard Install DVD 10.6.3 from Apple for $19.95.

Am using Macbook pro mid 2010 running on OSX 10.9.5. It does not read my old Seagate back up plus ITB ext hard disk which opens and works on snow leopard. The back ups were made on snow leopard and mountain lion. How do I make it work on Mavericks?

I have been making back ups on a Seagate Back up plus drive on a macbook pro running on Mountain lion. Sadly the mac was stolen and all I had was the seagate back up. I tried opening it on my old iMac running on snow leopard and after several visits to this forum managed to open it. The data was safe and sound. Now I have received a hand me down macbook pro which runs on osx 10.9.5. I'm assuming there is a compatability issue as the drive does not come on at all when I hook it up to the usb port. I checked the seagate drive once again on the imac and its light came on on that system. Then I suspected there may be a problem with this macbook pro usb port. But it seemed to work fine when i hooked my camera cord into it. Is it that I must reinstall mavericks. In which case how do I back up before reformatting or reinstalling. BTW I did the command+ R thingy and repaired my internal Hard disc which was showing errors. What do I do next, your help is most appreciated if you have had a similar problem.

Your 2010 MBP would be able to handle Yosemite, but I would strongly suggest that you get the current problem sorted out before trying to upgrade to Yosemite. I'd also recommend another backup that isn't created by Time Machine if you are thinking of upgrading. SuperDuper and CarbonCopyCloner can make bootable clones of hard drives. If you clone your existing system to a fresh external drive, you would be able to boot from that drive and recover quickly in the event that your Yosemite upgrade didn't work out. Time Machine backups are not 100% reliable.
It's possible that, if your internal HD is the one that shipped with your MBP in 2010, it may be failing. If it keeps needing repairs, that is probably a sign that it is approaching the end of its useful life.
Have you run Disk Utility's Repair tool on the external drive as well?
I mentioned the hub because some people have reported here that attaching their USB 3 drives through a USB 2 hub solved some disconnection problems. A good-quality powered USB 2 hub won't cost much.
My most recent brush with random disconnections involved a nice new OWC drive enclosure. I used the cable that came with the drive, but the drive kept disconnecting. Using a different cable solved the problem. You wouldn't expect that what appeared to be a high quality cable would be a problem straight out of the box, but it was.

Minecraft Won't Launch Because of a Java or Root Certificate Error I Started Having When I Put The Install Disk in And Downloaded Mac OSX Snow Leopard

I need help. I recently tried opening Minecraft after re-installing Mac OSX Snow Leopard with the Mac OSX Install DvD and now every time I try to open the internet these stupid certificate errors come up and Minecraft says it can't launch because of a broken/missing root certificate

Hello Shelby,
Thank you so much for the details regarding the issue you are experiencing with the Snow Leopard installation. I recommend following these steps if you are having trouble installing Snow Leopard:
The installation wasn’t successful
If you were unable to install Mac OS X, try the following:
Disconnect any external devices you don’t need during installation.
Remove any cards from manufacturers other than Apple.
Try installing Mac OS X again.
If you were unable to install Mac OS X again, choose Utilities > Disk Utility. Select the disk on which you want to install, click First Aid, and then click Repair Disk. After repairing any problems, quit Disk Utility and then click Continue to try installing again.
If you’re still unable to install Mac OS X, try erasing the disk before installing Mac OS X. Before you erase your disk, try copying your files to an external disk. When you’re ready to erase and reinstall Mac OS X, follow the instructions in the “Restoring your computer to factory settings” section of this document.
I found this on page 7 of the Snow Leopard Installation Instructions:
Snow Leopard Installation Instructions

Thank you for using Apple Support Communities.
Best,
Sheila M.

External hard-disk not working with firewire under Snow Leopard

Hi. I have a LaCie d2 external hard-disk that has Firewire 800, 400 and usb2. I previously used it on my old (angle-poise) iMac connecting using the Firewire 400 socket. I've just a got a new mac with Snow Leopard and I thought it would we best to connect to the LaCie with Firewire 800. However when I do this, the disc mounts ok, but browsing in the Finder is really slow and copying files from the disk to the imac seems to work at a really slow rate (less than USB1 speed) if at all ! However, I switched to using the USB2 connection instead and it works like a dream. What gives ? Is Firewire in Snow Leopard buggy ??

There's no problem with the drive.
Maybe true, and the drive would probably work fine with Leopard. One thing that's obvious is that Apple did make changes in the way that FireWire works in Snow Leopard. Many drives and drive manufacturers work well with SL, but there have also been reports of firmware issues by Western Digital and other companies.
Have you checked with your vendor to see if they are offering a firmware update for your drive?
BTW, I got a new FW case a few months ago while at a Fry's electronic store. The brand new USB2 and FW400 cables worked fine. The FW800 cable did not, but another cable came to the rescue. Just saying...

HOW DO I INSTALL DISK OF MY NEW 10.6 SNOW LEOPARD ? NEW MAC DO NOT HAVE DVD ACCESS . BUT I WORK ON OLD MAC 10.4.11 TIGER THAT DO HAVE DVD ACCESS . HOW DO I CONNECT NEW AND OLD TO MAKE IT WORK ? THANKS

HOW DO I INSTALL DISK OF NEW 10.6 SNOW LEOPARD ? NEW MAC DO NOT HAVE DVD ACCESS . BUT I WORK ON OLD MAC 10.4. TIGER THAT DO HAVE DVD PLAYER . I KNOW THAT SHOULD BE EAZY . THANKS

You'll need to provide some more information .... what current mac mini do you have? Click on the apple in the left corner of the menu bar, click about this mac, and what does it say for processor, memory, and os x version?
When you say you have no DVD, do you have the mac mini server or is the DVD broken?
You can't do anything with 10.6 Snow Leopard on a PowerPC mini, however, if it is an Intel-based mini, you could probably hook up the systems in target disk mode to install 10.6.

I just recently bought my friend's iMac 10,1 21.5in with all of his documents in it He lost his installer disks and it has OS X Snow Leopard. How can I restore it to factory settings? Or can I buy OS X Lion online and restore it to factory settings?

?

Sooner or later, you will need to have those install disks, so you or your friend need to call Apple, give them the serial number of the machine and ask for replacement disks which should be sent out for a nominal fee. Other than that, you could also buy Snow Leopard retail disk at various resellers or Apple store online for $29.
You will need that disk because: if you want to update to Lion and you purchase it at the app store, the license for it is not transferable, so if you ever sell that Mac, you are required to uninstall Lion and reinstall the original system (which you will need the disks for). The disks also include diagnostic/repair software.
So, it's best to have the disks; and, if you do purchase and install Lion, make sure you make a complete backup - bootable clone or Time Machine just in case.

Disk Utility: cannot Repair Permissions, even on Leopard installation disk

After reinstall of iLife '08 and Software Update completed, I ran Repair Disk Permissions. Got an immediate red note "error: The underlying task reported failure on exit (sic)." with a flag: "First Aid failed. Disk Utility stopped repairing permissions on 'Mac HD...' because the following error was encountered: The underlying task reported failure on exit."
I went to my Leopard Installation disk and ran "Repair Disk." No problem found. From the Installation disk, ran Repair Disk Permissions. got the same RED INK comments and flag, First Aid failed.
Restarts don't help. Also, so far I have not found an application which is NOT working despite this Disk Utility problem, happy to report ;-))
Additional background. I was reinstalling iLife to fix iPhoto after a clean reinstallation of Leopard and reincorporation of files and apps vis Time Machine. It had been several weeks and iPhoto appeared to be the only app which was not quite right.

Disk Repair can trigger "underlying task" but I've never heard or seen a Permissions Repair do so.
You should never use the DVD to repair permissions. You should be using the same OS version. And of course you can always repair permissions from your boot drive; or from backup/clone or alternate "emergency" drive. Otherwise, the DVD and older version of DU will be wrong.
I know I read that on MacFixit, but I am not sure I bookmarked it.
Don't rely on Apple First Aid, even a clean bill of health doesn't mean there aren't problems which Disk Warrior can deal with.

How do I make a back up system disk. I wish to run snow leopard and Lion on 1 drive.

I wish to run Snow Leopard and Lion on 1 Hard Drive. I need to back up snow leopard and then install Lion. Any suggestions on how to do this?

Too follow up on this topic - I have recently upgraded to 10.8.2. I have a complete backup HD with SL inclluding some SL-only programs on it. What I want is to make a small size, just SL and my few programs, hard drive with which I can boot when needed. Is it possible to trash all the many programs I have on the SL drive and just keep certain ones? How?
Thanks you for any advice,
John

Safari in 64-bit mode on Snow Leopard does not play YouTube videos

Recently Safari stopped playing youtube videos while Safari is in 64-bit mode. The entire page renders correctly; however the area where the video is supposed to play remains a black box without controls. I can watch video from other sites, or I can watch video from youtube if I use another browser like firefox. Additionally, I can go to the youtube video owner's channel and view videos there just fine. It's only when I try to view videos that use the "http://www.youtube.com/watch?v=" method of displaying a video using Safari in 64-bit mode that it fails to play -- it plays fine with Safari in 32-bit mode.

It's not !. Flash player 10.1 is no better (as you can verify by downgrading here http://kb2.adobe.com/cps/142/tn_14266.html)

Disk utility repair permissions not working in leopard

any ideas why my premissions repair are not working in my new leapoard is there a free phone to apple
because i bought my os x 10.5 from them

Tony, if you think it isn't working because all you see is the blue & white "barber pole" display instead of the all blue progress bar during the repair, rest assured that this is just a display bug & the repair actually is being done. It can take a long time for the repair -- much longer than in Tiger, so be patient -- give it as much as 10 minutes or more to complete & you should see the 'permissions repair complete' message eventually.
If you are seeing something else, my apologies for assuming otherwise. Please describe more about why it isn't working & perhaps we can help you.

What & where to get version of disk utility to use for mac os x 10.6.3?

what now? can somebody please advice what version of disk utility to get and where to get it.
thanks.

You either messed up the install or you subsequently copied an older version of Disk Utility from another machine, an old backup or the like. It's hard to know exactly what happened, but without more info I would view your system as potentially compromised and would recommend reinstalling it. Just run the installer and install on top of the system you have currently installed. It'll replace all the system components and leave everything else alone. (Of course, it should go without saying that you should have a good set of backups before doing anything like this.)

Time machine and backward compatibility to Snow Leopard

Please bear with a long background explanation but I am not sure what is relevant. I have two Mac notebooks both backed up using Time machine to separate USB Hard drives. I upgraded to Lion on both machines but decided to revert to Snow Leopard on the MBAir (instability in one application that I use a lot). I backed up the MBA using time machine to the USB drive and did a second backup to the NAS. I then erased the MBA hard drive using Disk Utility and tried to reinstall Snow Leopard using the "MBA Software Reinstall Drive" (a USB flash drive). Following the instructions that came with the drive didn't work and neither did the (different) instructions in the user guide. I then tried using the Recovery drive on the MBA and Disk Utility to install SL. I did some thing wrong (but I am not sure what) and it told me I could not install SL to the same drive. Eventually I got the OS installed from the USB flash drive.
Perhaps foolishly I left the USB backup drive connected to the MBA during this process. When I had fininshed the OS installation I looked for the Backup drive and couldn't see it. I checked Disk Utility and it showed the drive but did not recognise the name of the partiton and said the partion was not mounted. It would not mount the drive and had no options to repair or verify disk. There was some other information but I did not make a note of it. I tried to read the drive on the MBP and it opened for about a mintue and I could see the files but then it disappeared from the MBA - same story. I tried to repair disk in Disk Utility but it said there was no problem with the disk.
This morning, I connected the drive to the MBP (NB running 10.7.2) again to see if I could see what the problem might be and the backup files were back and presumably accessible.
OH! I just reconnected the USB drive to the MBA (running 10.6.8) and got a message saying (the dialogue box has disappeared) something like: it could not read the disk because it was written in 10.7.2. I guess that is the explanation but where do I go from here? It is not at all helpful to do all the backups and then find they are not backward compatible.
Is there a way for me to get the MBA to access the Time machine backup via another computer? Or can I do use a different method to access the data?
NOPE. Its happened again. I just reconnected the Backup Drive to the MBP (running 10.7.2) and now I can't see the disk. Disk Utility shows the partiton as unmounted and once again it won't mount. This time there was a repair option and I clicked it and got the following error messages: "Disk Utility stopped repairing 'disk3'" (it seems to have given it this name) In the 'Details" it said
Invalid Volume Header @ 0: incorrect block type
Invalid Volume Header @ 999539297792: I/O error
disk3 is not a CoreStorage volume
Error: Storage system verify or repair failed.
I don't know if this is an OS problem or a disk problem or both. Any thoughts?

I would say disk problem.
If it were mine, I would reformat it and see if that corrects the problems.
If not, it is time to send it to recycle.
