Builidng RAID on mac pro using disk-utility

Hello,
i want to build a RAID on my Intel mac.
First idea was using Disk Utility (DU).
Is DU able to create RAID 5 or only RAID 0/1 ?
If yes, and hints / or useful links ?
I have googled for a while but most hints are regarding raid 0/1 and/or mac xserve systems with specific cards/controllers
or should i use: softRAId app ?
and:
if there is a solution:
is the software raid 5 at apple really too slow to be happy ? is hardware-raid the only working solution ?
best regards
fidel

Check out some of the PCIe hardware controllers. There is CalDigit
RocketRAID reviewed by AMUG (they do excellent in-depth reviews).
Areca ARC-1220 RAID might be an option at some point. Would be nice if it did - but I don't see Mac Pro or OS X support.

I prefer SoftRAID, but you'll have to wait for 3.6, or do as some and use Apple's and create RAID 1+0. Or XRAID

I was erasing my Macbook pro using disk utility and it is frozen? Help!?

Ok So I was erasing my macbook to restore it using the disk utility. When I clicked erase it began the proccess. It has been stuck staying unmounting disk for a few hours now and the mouse wont move. I am afraid to restart it because I dont want to mess up the process and destroy my computer. Can someone help?!

mac_daddy02,
if you’re trying to erase your Mac’s internal disk, what do you fear might be destroyed by interrupting the erasure?

Creating RAID doesn't work using Disk Utility

When I try to create a RAID in Disk Utility, the pair gets corrupted and I get an error - "couldn't find RAID".
What is missing? Is there something else to install?
I'm trying this on an external USB drive.

I gave up.

Cloning HD to a new HD using Disk Utility

Hi,
I'm trying to upgrade my hard drive (500 GB) to a 1TB hard drive on my Macbook Pro using Disk Utility. Here is what I have experienced so far...
1) I placed the new HD in the enclosure and reformated it to "Mac OS Extended (Journalized)"
2) I restart my MBP and holding down to "Command + R" during the initial grey screen comes up - then selected Disk Utility from the menu (I'm currently running Mac OS 10.8.1)
3) Then the process starts with "Copying Blocking" and it shows that the whole cloning process is estimated to take about 2 days and 6 hours... Is that even possible? I'm using an enclosure that supports USB 2.0
4) I have read a few other options in cloning a HD using a software called CarbonCopyCloner - and it is said that it will be much faster compared to Disk Utility. But I just don't want to be pay for the software simply for HD cloning; figured disk utility is just as fine as long as the end result is the same as CCC.
I'm wondering if there is anything that I've done wrong as the approximate time required is simply WAY TOO LONG! Or is it because of the enclosure that I use that is slowing down the process (especially with USB 2.0)?
Also I'm following the cloning process from another post (https://discussions.apple.com/message/15431074#15431074) - and one of the disk preparation step states:
5. Set the format type to Mac OS Extended (Journaled.) Click on the Optionsbutton, check the button for Zero Data and click on OK to return to the Erase window.
And I don't seem to be seeing the Option button... All I see under Erase is a "Security Option" tab, but that doesn't lead me to a Zero Data button.
Hope to get some feedback on this soon so I can upgrade my HD asap. Thanks in advance
Peter

I've always done my cloning using carbon copy cloner - it is a 30 day trial.
I've never cloned using disk utility so I couldn't tell you.
I can however, give you the step by step with carbon copy.

Cloning drive to external & partitioning using Disk Utility.....!

Hi,
I wonder if someone is able to answer my questions and offer some advice and help.....?
I am purchasing a new external drive and would like to know how to clone the internal drive of my Power Mac G4 using disk Utility to the external drive, so that it is also bootable. I have seen that there seems to be more then one way of doing this within disk utility, but would like to know which is the best way?
1. Please could you take me thorough the steps as I have never done this before?
2. Would it be wise to partition the external drive to keep the cloned bootable system seperate from the rest of the content that will be placed on the external drive or not? If so again please could you take me through the steps on how to do this (partition external drive)?
3. Prior to partitioning the drive is it necessary to delete the new external drive even though there is nothing on it? As I read someone that this need to be done, but didn't quite get that!
Any help you can offer would be greatly appreciated.
Thanks in advance

Hello,
Hopefully it'll be an External Firewire drive, as USB cannit be booted from on PPC Macs.
I wouldn't use Disk Utility, there are easier ones for free.
I strongly recommend that you get a good Firewire drive to Clone your Internal drive to...
http://eshop.macsales.com/search/firewire+drives
Many of those come with Backup SW, or...
Get carbon copy cloner to make an exact copy of your old HD to the New one...
http://www.bombich.com/software/ccc.html
Or SuperDuper...
http://www.shirt-pocket.com/SuperDuper/
2. It depends how big the new drive is & how much space is used on the current drive.
OSX loves lots of free space on it's boot drive for VM & other temp files, I don't feel 50% is too much free space to leave.
3. Normally isn't needed to Zero the Drive, but you may have to foprmat it...

HT1553 Does using Disk Utility also backup MSOffice 2008 (Mac) software already installed on my Macbook Pro with Snow Leopard? If not, how would I do that?

Hi,
I'm looking to upgrade from Snow Leapord (10.6.8) to the new Mountain Lion. Have a lot of applications and softwares that I would like to back up when installing the new OS, such as MS Office, Adobe Photoshop and Illustrator. Any ideas on what is the best way to do that.
I'm not too tech savvy, so a simple solution would be appreciated.
Thanks,
Shyam

If your not very tech savvy, I would have someone assist you in the upgrade process as your about to inflict major change on your life and computer.
There are some things to consider before you upgrade.
1: The age of your machine:
My advice has been if your Mac is less than two years old and has a dedicated graphics (not all only Intel HD 3000 or 4000 CPU graphics like the 13" has)) then you stand a very good chance of 10.8 (or 10.7) running fine on your machine.
In either case you need to check the specifications of your machine to see if it meets Apple's requirements, and unfortunately those requirements are a bit low, resulting in a slower machine when you upgrade.
https://en.wikipedia.org/wiki/OS_X_Mountain_Lion
https://en.wikipedia.org/wiki/Mac_OS_X_Lion
(note: 10.7 is no longer being sold via the AppStore, you should upgrade to 10.8, however some machines can't, you can call Apple Sales to upgrade to 10.7)
If your machine originally came with 10.5, I would say forget it. Mac's don't last forever and laptops usually have a life of about 4 years with normal use. Desktops last longer of course and can withstand more OS X upgrades if Apple allows it.
2: The age of your software.
10.7 and 10.8 will not run PPC based software of old like 10.6 does, also upgrading to 10.8/10.7 may require expensive software upgrades that can hit you unexpected. Consult this site and your other needed software and hardware drivers/software (for printers/scanners,custom keyboards/mice etc) BEFORE you upgrade the operating system.
http://roaringapps.com/apps:table
3: Carbon Copy Cloner or SuperDuper "clone" (payware)
Your OS X boot partition to a new/reliable, blank powered external drive and use Disk Utility to Repair Permissions on both afterwards. You can hold the option key down and boot from this clone drive to use the computer like before if your OS X upgrade fails and the machine gets bricked. You can also use Disk Utility to erase the entire internal drive and reverse clone if you find out the OS X upgrade is not to your liking.
Make sure all other drives are disconnected, like TimeMachine when cloning or upgrading OS X, thus when you reboot TimeMachine doesn't self update itself, which can lock you out from going back in time to restore from.
Note: If you have Bootcamp, you can clone that with WinClone (payware) to another drive and recreate Bootcamp later and restore it.
4: Some firmware updates can possibly "BRICK" your hardware
Firmware updates progress in a forward manner and can't be downgraded, so what sometimes occurs is a software error by programmers or a hardware glitch on your machine won't 100% cooperate with the firmware update and thus your machine will fail to function. Sometimes even a interruption in the OS X upgrade or firmware update process will cause the problem. When this occurs, a trip to a Apple Repair is in order and if your machine is out of AppleCare (3 years) or the 1 years standard warranty your looking at a very expensive logicboard replacement. At this time you usually consider the cost not worth it and rather spend the money on the newer machine, especially if it's 2-3 years old. This can come as quite a shock as you expected to pay $20 for a OS X upgrade and now have to buy a whole new machine.
You can't not upgrade the operating system for security and bug fixes, however you make sure you have AppleCare that will protect you for three years if such a hardware bricking occurs. If you don't have AppleCare you might want to reconsider taking the chance upgrading the operating system and thus the firmware.
AppleCare can be purchased within one year of the original machine purchase, it gives one 3 years of care from the date of machine purchase, not from the date of AppleCare purchase.
5: Market share of OS x versions (apx)
10.4 4.5% security updates > no
10.5 15% security updates > no
10.6 52% security updates > yes
10.7 30% security updates > yes
10.8 2 million upgraded so far, just released
6: Your decision to upgrade or not
It depends upon your computer technical ability, the age of your machine, your software investment and your budget.
Can you afford to pay for professional assistance if your upgrade doesn't go as expected? Are you in AppleCare?
Can you afford to pay for upgrades to third party software?
Can you afford the downtime while your machine is being repaired?
Can you live without the "new features" newer OS versions provide?
Does your hardware even support the newer features?
You might decide the upgrade is not worth it for your older machine and decide to ease yourself into a new machine gradually. I took this approach with my 2006 MacBook Pro, buying a Early 2011 model. I then upgrade to 10.7 on the older 2006 machine and glad I did, because it got bricked. Turned out 10.7 was a pretty awful upgrade and I was out of AppleCare, however 10.8 seems to be "normal" far as OS X upgrades go, some problems but not mass bricking of machines.

I have an MacBook Pro 10.6, using disk utility I tried to verify my disk, but it came up with the message, please use your start up disk, I tried this, starting the computer up and pressing C, but it ejected the disk, the same thing happened while I running the computer. Is the hard drive damaged as laptop doesn't seem to recognize the start up disk ? If so, I presume I will have to put in a new one.
There haven't been any problems with the computer, apart from a sticky curser,I have run a permissions programme from disk utility, there were a lot of different ones, but it seem to be able to fix them.
Any comments or ideas ?
Thank you in anticipation.

First backup your users files off the machine to a external storage drive (not TimeMachine!)
Most commonly used backup methods
Next to startup from the disk, have it inserted, hold c or option/alt (wired or built in keyboard) and then boot the computer and or select the disk when it appears and click the arrow.
Disk Utility is under the Utilities menu on the second screen.
Step by Step to fix your Mac
If you used the wrong 10.6 disk, it will spit it out or have issues, use the one that came with that machine or if it's defective, call Apple for a new one.

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.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
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.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

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?

There is no option for "DVD and CD Sharing" on a 2011 Mini because it doesn't have an optical drive to share. That option is available only on computers with an optical drive to share.
That option is used, on the other "donor" computer with an optical drive that you want to use/share. On the other computer you turn on "DVD and CD Sharing", allowing its optical drive to be shared. Then on the Mini you connect to it with "remote disc".
I believe you're thinking about the "DVD and CD Sharing" System preference in reverse; you activate it on the computer whose optical drive you want to use/share, not on the Mini without an optical drive.
See the following which explains how to set up and use remote disc: http://support.apple.com/kb/HT1777?viewlocale=en_US

I am trying to install win 7 32 bit but before i partition my mac osx an error message pops up with the above wording...I went to disk utility and it is already a single mac osx (journaled). any help would be great and much appreciated..thank you for viewing.

The error message must be the title of 100s of threads.
Do you know how to backup?
It can't move files, some are fixed, the free space has to also be unfragmented contiguous chunk at the end of the drive.
Disk Utility Restore tab (and Help menu).
and of course external backup drive. And backup is step #1. There is a PDF you can save or print from the Boot Camp Assistant.
If you only have TimeMachine for backup you might want to install OS X anyway on a small 30GB partition (shrink partition size) or use your OS X DVD.
From OS X DVD go to Utility and then Disk Utility. Restore to another drive and that should be then bootable.
Or pick up SuperDuper or Carbon Copy to clone-backup and use one of those.
iDefrag $$ may be able to optimize the free space.
But it is wiser to first insure any data and files are backed up before changing or installing another OS, and before changing partitions around.

Why have my Ext. USB2 HD's Failed to Mount after using Disk Utility in 10.8.1 on Retina Pro

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,
