Disc Utility - warning if RAID HD fails ?
I would like to set up an external RAID1 in a Sonnet JBOD ( Fusion D400P ).
I just learnt, that if I set up this RAID1 with Apples Disc Utility, there will be no automatic warning if one of the drives is failing...
Is that true ?
Do I need to set up the RAID with SoftRaid to be on the safe side ?
Cheers - Steffen

What make and model drives? Not all work, or work well, and Samsung F1s have specifically been sited as not working with Apple Pro RAID.

I hope im in the right place, I have iMac 2.4 GHz intel core 2 duo running 10.6.8. I have problems with iPhoto so a ran disc utility repair disc which put up the following
WARNING SUID file system/library/core has been modified and will not repair
I have no idea what that means but I have a feeling it has something to do with iPhoto being messed up. Any suggestions please but please keep replies simple this is way out of my comfort zone.
Mike.Mike, it sounds like there's a problem with the drive, but most likely it has nothing to do with iPhoto per se. I'm guessing you ran Disk Utility directly without booting the Mac in Recovery Mode, or from an Apple OS install disk? In other words, you ran DI just from the Utilites folder? If that's the case, the issue is you can't repair a disk that is being used to run the system at the same time. There is a way round this though.
Hopefully, you still have the DVDs/CD's that came with the Mac? If so, you need to insert the OS install disk and restart, holding down the "C" key, then run Disk Utility again. Here's a page I found describing nicely what to do and what you'll see:

How do I break a mirrored Raid in disc utility?
I have two 2.5 TB LaCie Biggest S2S external drives that I mirrored using Apple's Disc Utility. Now I would like to break the raid to free up Drive B without compromising the data on Drive A.
I have been told I could just unplug Drive A, erase and reformat Drive B, then plug Drive A back in... but would appreciate to hear from someone who has done this before and can confirm this is the right way to go about it.
Many thanks.Thanks. I would do that, but when I click Delete, it gives me a warning that says:
Deleting a RAID set will destroy all information on the all the disks of the RAID set.
Are you sure you wish to delete the RAID set?
This makes me nervous, as I can't afford to have all information on both disks destroyed. Are you saying it won't destroy my data on both disks? -
screen saver does not turn on. Have run the disc utility to repair disc permissions. Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired.

Reinstall Lion, Mountain Lion, or Mavericks without erasing 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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless. -
While running verify disc in disc utility on 251 GB SSD SM256c Media I came up with this message: Alert system verify or repair failed. In the descriptions box of history it said, problems were found with the partitions map which might prevent booting. This is followed by a message in red reading, Error: Storage system verify or repair failed. At the time I was down loading raw pictures off my camera through a card reader across my computer to a relatively new 2TB Western Digital portable hard drive. after about 13 to 15 pictures downloaded that drive faileded. My Mac Book Air works fine, but i get this message now everytime I run disc verify on this disc. The Macintosh HD checks out fine.

o.k. So, I've been tinkering with several "self help" fixes for several days now with no positive results. I'll explain my initial problems and then end with my most current situation. In hopes that someone out there will have a good suggestion or possibly remedy for the issues i'm facing
First, my problem started after my wife played a game on my macbook pro and the computer froze. She went into a panic and decided to shut down via power button. When computer restarted she got the blinking file/grey screen and that problem continued for a couple of days before I began using steps from various support topics from apple concerning the grey screen/blinking file folder.
Ultimately, yesterday I decided to erase my Macintosh HD file as one tip suggested. Following the brief online and on screen (via the process) tips that were there. Once that was completed I attempted to reinstall snow leopard (my most current version on hand) into the pc.
At first, I thought this would work. It looked promising. But, after several hours the installation screen returned with failure. I attempted to repeat. And, even repair drives during this try and re-try process.
Now, today, one of the drives.. "hitachi..." states that it's failing and is in red letters with no ability to repair via the disc utility screen. The Macintosh HD drive shows that it's o.k. But, this drive is listed under the HItachi drive so I think that's where a problem might lay.
So, I guess my question really revolves around.. What if anything can I do to get the hitachi drive back up? (short of taking it to a repair facility and replacing.)
And, how on earth can i get my OSX back up to I have a laptop again.
Operating on a macbook pro here. It's my lifeline. Otherwise, I am using a Windows desktop that i'm not that fond of. lol
I'm trying to bring this 2006 laptop back to life. Trying to avoid a rather expensive repair or the purchase of a new laptop. Also expensive...
Any help would be appreciated.Well, running on a 2006 model. I did not have a startup disc. Initially, it booted up on original software in 2006. Since then, I've upgraded to 10.6 via a box set. And, since then I think I popped it up to lion.
All I have on a disc is snow leopard. And, I can't get farther than the setup screen due to hard drive. I'm taking to a apple authorized repair store right now. We'll see what they tell me . I'm just going to weigh the cost of repair vs. buying new.
Another bad, stupid thing is I had no means of backing up my stuff. So, I might have lost things like music, vids, etc. we'll see if they can recover. If the cost is too much for repair I might just forget it and start over with a new system. Just not sure at this point. -
Brand new Mac, had to erase drive through disk utility as time machine back up failed on initial setup, USB cable popped out Now can only access disk utility as won't load to log in screen. The only has the option in disc utility is to re-install Mountain Lion which my Mac won't allow or loading another time machine back up but after an hour of it processing, that didn't resolve the issue either! The time machine back up is the latest back up of my Mac Book Pro which was using OS X Maverix. I'm guessing I'm going to have to take my Mac to the store but that would be a hassle so does anyone have any ideas?
Follow this guide using another Mac.
Insert your newly created Mavericks USB into you Mac, press the power button and then hold down 'option,' until it gives you an option to boot from the USB. You will then be able to erase the internal disk with Disk Utility and reinstall Mavericks straight after.
After that you should be able to use Migration Assistant to restore your applications and user data. -
I have MacOS 10.5.8. It is not booting. It stops at the blue screen. I used the disc utility - verify disc. I get the following message - Invalid sibling link. Volume check failed. Error: Filesystem verify or repair failed. Please give a solution anybody?
Many times I tried to simply update from 10.5.8 without any success. It starts and after few minutes ...
I used many different install disks (I bought ofiicial release from Mac seller), so I think this is not a problem with wrong version or bad install disk. A few days ago I've got back my computer from Apple technical support and technician told me he had this same problem with system installation -
Setting up raid O in disc utility
I want to create a raid O in Disc Utility on my Mac Pro 2.8, 8 cores.
I have 2 drives that i've been using in my previous powermac G5 stripped as Raid O with a Sonet 8 port E-Sata controller card, they worked fine and fast.
In my Mac Pro do I need an E-Sata Controller card like one from Sonet with 4 ports in order to achieve a raid configuration and speed?
With out a controller card, stripping 2 drives, does Leopard sees the 2 drives as one large drive without the speed?
Another question, when stripping the drives as a raid O configuration it asks which as an option the sector block size, 16, 32, 64, 128, and 256,
for video editing which sector size be best suited.
any suggestions would be appreciated.
thanks

If you want to do software raid 0 with external drives or enclosures, then you can use either the ODD sata ports to esata adapter OR any esata controller card. Doesn't have to be from sonnet (although they are very solid).
{quote:title=With out a controller card, stripping 2 drives, does Leopard sees the 2 drives as one large drive without the speed? }{quote}
This question is a little confusing...first, you don't need a controller card to stripe 2 drives together. It can be done merely in disk utility. Also, whenever you make a raid, it always shows up as 1 drive.
For the block size, if you're doing mainly video, higher sizes will be better, as your files are bigger in size. I've never heard much on using 256K, but afaik the video norm is 128K. However, if your files are very large, I don't see why not to go for 256K. -
My old internal (self installed) Seagate HDD broke down, and couldn't be fixed with disc utility (from install disc). I bought and installed a new hybrid Seagate HDD, and did several clean installs of Mavericks, but the problem keep occurring - on the new HDD, just as it did on the old one.
I can't run Hardware test. Happened both on 10.9.0 and 10.9.1.
Will try to repair with DiscWarrior later.If both the HDD and the hybrid disk are failing, your problem may be the SATA cable in the main HD bay. You might want to search eBay for Apple part # 922-9751, or if you want a tested cable, pay the higher price from ifixit -> http://www.ifixit.com/Store/Mac/MacBook-Pro-15-Inch-Unibody-Early-2011-Late-2011 -Hard-Drive-Cable/IF161-086.
Worth a shot...

During a routine verify permissions using my disc utility, I'm getting a WARNING: SUID file "Systems/Library/CoreService….ent" has been modified and will not be repaired. What does this mean?? I'm not awawre that I did anything to cause this and is it somethingI should try to fix?
1. It means that the current software is installed.
2. It's not something you should try to fix.
3. Verifying and repairing permissions shouldn't be done as routine tasks.

My external HD won't show up anymore on my desktop nor does it get listed in disc utilities. I tried to cennect it to another mac but it doesn't show there either nor in that mac's disc utility. I happened to re-start the computer while the hd was connected and now it doesn't show up anymore. I use it for back-up via Time machine. I could re-format and do the back up all over again but then I need to find it first. Please, does anyone have any solution to this problem?
It sounds as though the external drive may have failed. There's nothing at all wrong with restarting your computer with the external drive connected -- that's a perfectly reasonable and normal thing to do, done by countless users every day without any ill effects.

Archive and Install/Disc Utility issues -
I'm currently spending a summer abroad in South America, and have had issues with my Macbook Pro (early 2011 version) no longer starting up after some virus experiences last week. The computer hangs itself during loading on the white screen w/ grey apple and the spinning dial. In contacts with Apple Care as well as some Mac-saavy friends, the following situations have been tried:
Opening in safe mode - The loading bar (added at the bottom of the grey apple screen) loads about 1/4 of the way, disappears, and the computer hangs itself.
Opening in single user mode - I run the recommended sbin/fsck -fy command to clean up the hard drive. It comes back after having checked 6-7 parts, saying that the MacHD is in good shape, with a message following saying that something had been "modified" (forgive me for not remembering the correct verbage at present). I then run the same command again, resulting in a message that the HD is clean and without error. I then "reboot" and remain hung on the white screen w/ grey apple.
Opening in verbose mode - I reach the following lines of text, and then there is no further progress:
enable
IONetworkController::enable
createMediumTables
enable end
MacAuthEvent en0 Auth result for: 00:23:cd:1e:f2:c4 No Ack
same line as above saying "Auth timed out" at the end
Command+option+r+p - shock two or three times, (three startup chimes) and computer continues to hang itself in the normal spot.
- So, at this point I took the advice of Apple Care and a few other friends, and tracked down a "retail copy" of Mac OSX (10.6.3) in order to try to do an Archive and Install or any sort of Disc Utility via the startup disc.
Inserting the disc and holding "c" at startup results in the cd drive whirring the disc for a few moments, and then remaining hung at the same white loading screen.
Holding "option" during the startup gives me the option of loading from the HD, or the disc. Selecting the disc proceeds to whirr the cd drive, take me to the white loading screen with the grey apple, and... you guessed it... leaves the CPU hung.
My question is then, is my Macbook Pro unable to read this disc and execute Archive and Install/Disc Utility for hardware reasons as per the virus attack, or is the disc not compatible with my version of OSX (which I have since confirmed through my wife to be 10.6.6)?
Different sources have told me different things. The local AASP in Uruguay sold me what they professed to be the "latest" version of OSX - the 10.6.3, what's more for $55 dollars instead of the lower cost as available in the states (between $15-$30), so I am reluctant to go back to them for advice when they seem more inclined to cash in on my inexperience (Mac owner of less than a month) than actually fixing my issue. Apple Care told me that a standard "retail disc" should work, but I am assuming now that they believe I can snag the same version as initially came with my Macbook Pro. Should I be looking to have my wife mail my original OSX install DVDs down here to resolve this problem? Should 10.6.3-retail be working and is not for reasons I haven't identified? I have since done some online research and found mentions that doing any sort of HD partitioning or OSX reinstalls can only be accomplished by utilizing a disc of an equal or more recent version of the OSX (examples that 10.4 can't work on a notebook preinstalled with 10.5, etc). Does this translate to 10.6.3 not being able to function for my 10.6.6 MBP?
Any insight or thoughts would be much appreciated, as essentially all of my schoolwork and assignments are now trapped on an inaccessible HD. Thank you for your time.
- JosephI tried adding in a bunch of information about what your troubleshooting steps meant, but the server went into maintenance while I did. So, here it is again:
"Opening in safe mode - The loading bar (added at the bottom of the grey apple screen) loads about 1/4 of the way, disappears, and the computer hangs itself."
This is FSCK running, and gives you an indication of it's progress.
"MacAuthEvent en0 Auth result for: 00:23:cd:1e:f2:c4 No Ack"
This is either a failed DHCP request or ARP request.
"Command+option+r+p"
Command+Option+P+R - Resets PRAM. That's why p+r.
"Inserting the disc and holding "c" at startup results in the cd drive whirring the disc for a few moments, and then remaining hung at the same white loading screen."
This problem indicates that the disc is too old to boot your system. The reason for why this disc cannot boot is because it doesn't contain the necessary drivers for your model MacBook Pro. My mom and brother have similar models, and my brother had similar issues while in Japan. He went and got an install disc as well, which failed, I ended up stepping him through so that it would boot in Safe Mode, and then got it working in Normal Mode remotely.
FYI: Sophos has a free Mac Antivirus program, that is very processing friendly, and will scan in the background. You may wish to consider it as an alternative to Avast! if it continues giving you problems. Though I suspect it may be coincidence that your computer had problems shortly after Avast! cleaned up files. Let me know how it goes. You may wish to open up Disk Utility and check your S.M.A.R.T. Status. You want to make sure it says "Verified" If it doesn't say "Verified" then you have a problem.

OS 10.4.7 Disc utillity on old PowerBook HD
My OS 10.4.7 Disc utillity cant delete or format my "old" PB HD
Hi, hope someone can help me.
I got an older PowerBook G4 1Ghz with OS 10.4.7.
When I start on the OS DVD or an extern HD I can´t format or delete my internal HD with this new Disc utillity???
Symbols are marked red...
When I start in OS 10.2.8 and use this versions Disc utillity, I can delete and format my internal HD???
Why is that?
And since I have experienced some troble withe crash on the internal disc and since it is getting to smalle, I will replace it with a new bigger one.
Will I experience the above issue when I do so???
Kind regards Weimar.Hi Weimar
If the HD is healthy you should not be experiencing
any of these problems. Everything should work fine.
Have you tried repairing the Disk or running Hardware
tests on it? What's it's SMART status?
Matthew Whiting
Hi Matthew,
Ok,
the smart funktion failed.
And I have tryed repair using Disc Utillity and Tech Tool Platinum...
Sometime it seems that the HD is ok, and then when I installe system og other software it do funny stuff...
So I think I will go for a new HD
Thanks for your reply...
