Disk Utility RAID setup problem

I just formatted two 5TB drives in order to setup an internal RAID for an Intel Mac Pro (early 2009 OSX 10.10.1). I had no problem installing a RAID on 2TB drives a couple years back using Disk Utility. Now, the RAID option does not even appear for the new disks. I can see the RAID option when choosing the OS disk. The only other hint is Disk Utility says "this type of disk cannot be used as part of a RAID set". I have never seen this error. A disk is a disk (and a horse is a horse of coarse of coarse).
What do I do to make these drives eligible to be part of a RAID?
The disks are Seagate ST5000DM000. See image below for lack of RAID option.
Any and all assistance is greatly appreciated!!

Thses are normal but innocuous messages resulting from installing ARD and Java updates. If you now have Lion installed then these are left overs from the Snow Leopard system you upgraded. Don't worry about them. They will recur when you run repair permissions.

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
Quit and you should be able to install OS X now with your Apple ID and password.

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 Raid question

Is it software based RAID? or does the disk utility control a hardware based RAID?

For every disk drive I keep two backups. Rather than relying on mirror, which copies problems, and protects only from a hard failure, a FW800 and eSATA might be the way to go.
SoftRAID ($149 3rd party) will alert you on any I/O error and supports "stripe reads" from mirror if you go that route.
Zero your drive, backups, good maintenance. You can also backup to disk images.
Always always have an emergency boot drive AND a copy of the OS before you make any updates.
It is possible to partition a drive and then stripe or mirror using part of the drives to other identical drives. Performance of your "0+1" is poor.
If you are like most, over the years I've tried various setups and configurations, and continue to, in part to test and tweak, or to learn along the way. But backup sets are deeply ingrained from over 30 years of handling files, systems and data. And in the rare event of a drive failure, most of the time a simple reformat (or 7-way write erase nowadays) works. And there are programs to test and map out bad sectors. Heat more than anything shortens a drive's life, assuming the drive's mechanics are good (most are).
You have your drives, so can't sell you on which drives are enterprise, optimized or best for RAID (some are not suitable, and some have problems).

Disk Utility RAID Issue

I'm trying to determine if the problems that I'm encountering are a software issue or a hardware issue.
I'm setting up a Mac Pro with Leopard and have four Maxtor 6G160E0 160GB hard drives that I'm trying to set up as two Mirrored drive sets. Everything seemed to go fine, created the two mirror sets, installed Leopard, configured and tested two user accounts and Office 2004, then updated everything to the latest version. When done I shut it down planning on moving it to it's final home tonight.
But, when I turned it on both mirror sets were degraded - all four drives were still recognized as RAID slices but came up as failed in the RAID tab. I saw no errors reported in the log so I assumed that those two drives were faulty. I shut down, moved the good drives to bays 1 & 2 and rebooted.
First reboot gave me a prohibition symbol instead of the usual Apple. Powered down and on and it booted fine but the second drive came up as a failed RAID slice. Rebooted again and both were fine.
I reinstalled the two "failed" drives and reformatted them - both reformatted fine and mounted without problems. I unmounted the new partition just in case, but, when I tried to rebuild the RAIDs I get the following in the error log:

I'm at a loss at the moment. I am leaning towards bad drives, but FOUR bad drives all at once is suspicious.
I've searched for similar issues and found none so I thought I'd check here and see if anyone had any ideas.

G'day Zeekm,
Thank you for that. I did this and it seems to work. The Disk Utility GUI does not seem to work.
Hope this helps some one,

Disk Utility says no problems but Diskwarrior disagrees

Need some advice. I ran Disk Utility yesterday to verify my drives before upgrading to 10.4.4 on my Dual 2GHz. It came up with some errors but said it couldn't fix them. Went to Diskwarrior which also said it couldn't fix it. Did a safe boot which is supposed to force an 'fsck' but the system never fully booted from that, probably failed at the fsck (the fans turned on full blast at the grey bootup screen then eventually powered off by itself). When I rebooted, I ran Disk Utility and it now reports the drive is fine. Diskwarrior still scoffs at that though.
Disk Utility said something about File Allocation Table mismatch.
Diskwarrior said the directory structure could not be repaired.
SMART says the drive is fine.
TechTool Pro reports a Bitmap mismatch and could not repair the drive.
Thing is, I don't see any problems with the drive at all. System boots fine and there are no corrupt files. It's a 3 month old 300GB Seagate so I don't think it's a hardware problem. But I've had some kernel panics related to my video iPod (the one where the G5 kernel panics if you have low space left on the iPod) which is where I'm guessing this all started from.
I've left it for now with Retrospect backing up the drive to a new external 250GB drive I had to buy just for this. I was planning on formatting the problem drive, testing it again and then restoring the Retrospect backup. (The only issue I've had with Retrospect is I Duplicated the problem drive to that new drive and had about 4000 files with different dates. I'm hoping that doesn't happen using the Backup function instead.)
Is this the right path? Or anybody think it could be a hardware issue? I've never done a full system volume backup with Retrospect, will I run into problems making the restored drive bootable again? And last, are there any other programs I should try?
BTW, I thought Journaling was supposed to fix all this!!

My MacBook Pro 13 inch makes a clicking noise from the hard drive and can not start up in safe mode and normal. I then ran disk utility in recovery mode and disk utility shows no problems with the hard drive. What is the problem?

Please help me, I have a mid 2010 Mac book pro with a toshiba mk3266gsxf harddrive. It started making a clicking noise and then my computer crashed. I proceeded to boot in safe mode, but it doesn't work. When I ran disk utility in recovery mode, it showed no problem with my disk. Does any one know what the problem is?

Sounds like a mechanical problem with the drive and it ruined the sectors where the Macintosh HD partition (and OS X, and files and programs) reside, but not your Recovery HD partition.
If you held command option r while booting, that's Internet Recovery and it's loaded via the Internet, not via the Recovery HD partition on the boot drive, so that could mean the drive is dead mechanically or there is another issue.
In either case the drive will likely have to be replaced, it's a matter of what occured to where and the drive state if you can recover data or not. If you made recent backups then your fine.
My computer is not working, is my personal data lost?

H.D. Clicks When Booting But Disk Utility Says "No Problems"

My friend installed a new 300 gig Seagate on his G4 a couple of months ago. It has worked fine until now. Suddenly, it won't boot up from the HD -- just clicks. He gets the spinning ball and it freezes up. HOWEVER: (1) The icon does appear on the desktop and (2) When he starts up from the CD and runs Disk Utility, D.U. recognizes the H.D., checks it successfully, and reports "No Problems Found." He can hear it spin up and everything just fine when he is checking it with Disk Utility.
So, it seems to go into the "clicking and spinning ball syndrome" only when he is trying to boot up from it. Any ideas? Thanks!

Hi! Missing disk utility apps and problems with external disc

Hi everybody! after installing snow leopard, as a way to get to lion, I dont have the disk utility apps.
Besides Im having a lot of problems with an external new Toshiba 1T disc that I try to use with Time machine cause I daily receive the OSX msg CANT REPAIR THE DISK REFORMAT IT!
Thanks a lot to all of the community
I do love Apple product. And counting the days for the iOS 6 upgrade!!

Before you go to Lion, just a reminder. I know you recently moved up to Snow Leopard. Be sure that everything you were running in Leopard, and now in SL, will work for you in Lion.
Remember, Rosetta and all PPC apps are gone (Word 2004, some versions of PhotoShop etc) Check the compatibility list before you ditch SL.
As far as your Disk Utility problem, how hard is it to reinstall SL?
I've taken a screen shot of my Utilities folder to show you what you are looking for. The Utilities folder as mentioned above is in the Aplication Folder (or you may have pulled it out to the side bar as well, in which case there will be an icon and the word Utilities in Places in the side bar.

See a Disk Utility RAID on another Start Up?

Hey
we made a mirrored RAID with two FireWire externals. How can we see the RAID set while booted from another Start Up Volume - without the Holy Hard Drive Trinity "Initialize, Ignore, Eject" coming up?
Is there a pref file that need so to be copied over? BTW the set was created while running Server 10.4 - the other start up is 10.3+ - in case that makes a difference... (it's one partition tho.) Or do we say "ignore" that repair with Disk Utility?

RAID of any time created with Tiger are not backward compatible with Panther.
For that you would need SoftRAID or to create the RAID under Panther. Quite a few changes and improvements went into Tiger (and again w/ 10.4.4 I believe).
And, to really do FW800 RAID you want each drive on independent bus/channels as well (I had to invest in two PCI controllers).

Disk Utility RAID of 2 volumes, one drive mistakenly erased. Recoverable?

Thanks for any help.
I have a Mac Pro.
It has 2x 750GB drive formatted in Disk Utility as a RAID volume (striped).
I erased one of the volumes by mistake.
I know I can recover the data from the erased drive, but it will be useless without the other drive. So how would I go about restoring the data in such a way that it is recognized as the other half of the RAID volume again?
Thanks for any help.

The commercial "SoftRAID" ($149) http://www.softraid.com
... is able to convert Apple RAID to its own format, AND has had excellent success for others in recovering in some situations.
They have excellent support so email them; a demo; and good PDF guides for download are worth a read.

Disk utility raid

I'm planning on doing a concatenated disk set using disk utility for my external drives. But what happens if I had to reinstall os x, does it recognize the raid set? Or will I loose my data?
Thanks.

Yes.

Disk Utility Errors/ Mail Problems

My mail was working fine the other day, but suddenly it won't connect to any of my email accounts (gmail, university email account, etc). I tried installing Thunderbird and read my messages through that but it still won't work.
Additionally, skype stopped working too. It said I could connect but it would show that no users were online, when they were infact online. However, I reinstalled it and it solved the problem. But mail still won't work...
I looked at my firewall settings and they seemed ok.
The internet/network connections are working completely fine. I can browse normally with Safari. The only things that have changed are Mail and Limewire. Limewire no longer connects properly and mail can't seem to connect to any of my accounts. No preferences have changed to my knowledge. I even tried dragging the preferences folder to the desktop and let the preferences go to the default, however, Mail still did not work
AND I decided to run the processes in Disk Utility and it wouldn't even finish verifying the Disk! It said this:

HELP!

Boot into Single User Mode (command s) and run the fsck. The instructions are there when you get to the prompt: /sbin/fsck -fy
Don't use an older version of 10.4 than 10.4.6 to be safe, ie if you have 10.4.0 DVD it is recommend to NOT use it. There are 10.4.3 and 10.4.6 DVDs of Tiger.
Best: have and use an emergency boot disk on another drive, just need a small 10-20GB partition and update it with minimal Apple updates, and run your disk repair utilities from there.

Disk Utility and burning problems

I'm in the process of trying to back up my new emac (OS 10.4.2). I bought some CDRW disks (4X, 700mb) and I can quick erase them--but I cannot burn to them. I have all the proper authorizations (as I am the administrator) and my computer does burn this type of disk. The burn icon is dimmed when I highlight the CD disk in "disk utility". It also doesn't show up on my harddrive. It is listed as read only. I've tried two.
Is there an authorization I'm missing? Something else?
(This has not been an easy switch, since I can't seem to get my old iMac to talk to the new eMac either. That is next on my list)
Christina

Christina Wilson,
Welcome to the Apple Discussions!
Have you tried erasing the CD-RW disks before trying to use them? Insert the disk, open Disk Utility, select the CD-RW device, not the volume name (the device name is the one on top of the volume name), select the Erase tab, and see if the Erase button becomes active. After erasing, you may need to quit Disk Utility before the CD-RW blank will mount on the desktop (that's the case in 10.2.8; it may not hold for 10.4.2).
Have you tried running Disk Utility/ Repair Permissions on you new Mac yet? What about the maintenance scripts? A handy reference for this sort of OS X stuff is Dr. Smoke's The X Lab: The X-FAQs
