How do you break a RAID 1 created in Disk Utility and retain data?

Good Morning all !!
Quick subject question.
Background: I have 2-3 TB of important data that i use only rarely. I purchased two 4TB external drives. I could not use a 2 drive raid enclosure because of the fan noise in the studio. I selected 800 firewire fanless enclosures. The technican talked me into using the Disk Utility Raid 1 in Mountain Lion OS.
Problem: I only plug them in when needed probably once a week. The raid rebuilds every time I use the raid. That takes about a day. This arrangement is less than ideal.
Question: Can I break the raid and still have the data intact on 2 separate drives? Of coarse I would do it when they a rebuilt.
Thanks.
Mike

How can you change the primary partition in Disk Utility?

I have made another partition using Disk Utility to install Snow Leopard. On my main partition Lion is installed but when i boot into Snow Leopard and try to delete the Lion partition it comes with an error "This operation requires a newer version of Mac OS X for this disk". I tried deleting the partition from Recovery HD but it says it couldn't unmount the disk.
Is this because Lion is the main partition, can you even delete the main partition?
And if I do delete the main partition will i be able to move the Snow Leopard partition "upwards" in Disk Utility?

1) First of all what is GUID.
It's the "partition map scheme" Apple uses so your firmware knows what is what on your boot drive, what partitions there are and what format they contain.
2) Secondly, would I just be able to make a new image in disk utility and use that instead of an external hard drive?
No, you need something to boot off of and remove all data off the internal drive that's going to be reformatted with a new parttion, that's why you use the free Carbon Copy Cloner, it does both in one shot and it "blesses" the drive to make it bootable.
3) When I use Carbon Copy cloner will it only copy Snow Leopard Installation or all of my files also?
It copies everything in your Snow Leopard partition to the external drive, files, programs the OS everything except whats in the Trash.
4) In your 8th step you mentioned repairing permissions on both. Both of what?
Both drives, the internal and the external clone in Disk Utility (ignore the long list that appears)
It's a safety check to make sure your permissions are set back to original settings, I think the newer version of CCC now does this, but I havent' checked, doesn't hurt to do it again.
5) If you still feel like typing can you tell me how long this whole process might take?
Formatting a external drive
You should Erase with Zero option first, that will take a hour per 500GB
Formatting shoud be rather fast, a few minutes.
Cloning Snow Leopard to the external drive should take about a hour per 500GB
Formatting the internal drive a zero erase first for safety should take another hour per 500GB
Reverse cloning Snow Leopard back onto the internal drive should take another hour per 500GB
Good thing about it, it's pretty much all ciick and go watch TV while it works.
I was actually planning to make a Genius Bar appointment to fix it, by the way does that cost much?
No idea, but you don't have to pay if you get a external drive for $70 or so, CCC is free.
You get to keep the external drive and use it later for cloning as hard drives die all the time, the clone would get you back to using the computer.

Can a RAID created by Disk Utility be connected to another Mac?

Hi There,
We're looking to upgrade our workstation storage (4x workstations) and have recently had issues with third-party RAID cards and third-party RAID enclosures.
If we were to purchase a JBOD enclosure and use Disk Utility to create the RAID, would the RAID be recognised on different Macs if the enclosures were moved around? I realise performance would suffer compared with dedicated hardware RAID.
The main reason for using disk utility is that the smaller 4-5 disk enclosures don't seem to have RAID 10 and we've noticed a rebuild issue with 2 of our RAID 5 enclosures. After reseraching online, it turns out to be an issue inherent with RAID 5/6 (bad sectors causing issues on rebuild).
So we're thinking of buying enclosures with JBOD, then using Disk Utility to create RAID 10.
Hope that makes sense, any help or suggestions would be much appreciated.
Cheers
Ben

Grabbed a JBOD enclosure today and discovered that RAIDs made on one Mac are recognised on other Macs.

How do you change burn/writing speed in disk utility

Ok I have some ISO files that I am trying to burn using Disk Utility. At the end of the burning process I get a error message of "Unable to burn (file name) ... code 0x00000005
I another post where error code 0x00000005 was talked about. A suggestion was made to slow down the burn speed and that worked for this person. My issue is how can I slow down the burn speed via disk utility before the process starts.
Please help with this issue

Click the blue triangle near the top-right of the burning window to show urn options.

Logic pro 9 quits on startup. How can this be resolved please? Checked disk utility and all seems to be ok...

Hi
I've tried top open logic pro 9 today which I use daily and have been for the last 4 years. All software etc. is up to date. However it just quits and I get the 'logic pro quit unexpectedly' message. I've tried this several times in the last hour, including a restart and checking disk utility etc. Anyone else have the same problem? And if so, how did you resolve it please?

Failing that....
Please download Etrecheck from here...

..and then launch Logic Pro
Now run Etrecheck and post up the full report here....
Thanks...

How so I break a raid mirror yet retain data?

I have 2 500g SATA drives on my Mac Pro3.1. They were set up by a friend as a raid mirror using the disc utility software. My question how can I break the raid "mirror" and use these harddrives as individual harddrives???
Thanks
Rich

From DU's Help:
*To delete a RAID set*:
Back up any important files.
In Disk Utility, select a disk in the set that you want to delete, and click RAID.
Select the RAID set.
If you’re deleting a mirrored RAID set and you see a Convert button, click it to convert the RAID set from version 1.0 to version 2.0.
Deleting a version 2.0 mirrored RAID set leaves a usable copy of the set’s files on each disk. Deleting a version 1.0 set leaves the disks unreadable.
Click Delete.

How do you setup RAID 10 with Disk Utility?

I read a post that indicated a Mac Pro user created two mirrors and then striped them with Disk Utility to create a RAID 10.
I tried this but Disk Utiity will not allow me to stripe the two mirrors. I tried dragging and using the "+" button. In each case no RAID 10 could be created.
Could someone list the exact procedure for creating a RAID 10 using Disk Utility?
Thank you

I have Mac OS X Build 8K1124 and I believe that came with my Mac Pro as I've not required a Mac OS X update via Software Update.
Now, I have to honest, I'm not entirely sure that was the exact process. As you can appreciate I don't have another 4 drives to try this again so I'll do my best here.
It's definitely right up until the part of making the mirrors and unmounting them, that I know for sure. What I don't remeber is what I had selected to get to the RAID tab to create the Stripe Set. I believe I had one of the mirror partitions selected, that is, either "disk5" or "disk6", which brought up the RAID tab that then allowed me to create the stripe set.
I then created the set and then dragged the mirrors (I believe disk5 and disk6) into the set.
If you can't do this can you let me know how your situation deviates?

How do you break a closed path?

It's infuriating: Not only is there no indicated means of doing this in the GUI or menus, but there's no result in attempting to search the Web for it.
Once a path is closed, how do you break it open?
And while I'm at it: I have a vector mask. I want to draw another vector shape and subtract it from this vector mask. How would I do this?
Thanks!

Thanks, guys. I will resist going on a tirade about how pathetic this UI is (Delete key having undocumented functionality different from Delete in the menu).
Question about the multiple shapes, however. I've selected the vector mask and picked the freeform pen tool to add another shape.
The original shape is the boat outline, and everything around it was masked out. Now I want to draw another shape at the bottom for the "waterline", also eliminating its contents from the final image. But as you can see, the result only shows the intersection of the two shapes. No matter what I select for "path operations" in the toolbar, the result is exactly the same. Except "merge shape components"; then the empty outlines disappear and I'm left with just the filled section.

How can you make your persona show on the top and bottom? Also can you make it bigger at the top to show more of the picture?

Add extra empty toolbars if you want to see more of the persona.<br />
You can create extra toolbars to get extra space via View > Toolbars > Customize<br />
You have to put something on a toolbar (drag a Space item onto it) before closing the Customize window because empty toolbars are automatically removed.<br />

How do you clean out a start up disk

Hi, How do you clean out a Start up Disk to gain more room?
Thanks

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

In iMovie 11, how can you cut/paste a clip that has subtitles and actually have the subtitles get cut/pasted. When I try, the subtitles disappear into the void and I have to do the subtitling all over again.

I am considering buying a new MAC laptop to run LOGIC for composition and band live/recording, but which one is best as I do not want to spend too much money? Does it have a line in and how do you monitor sound? Will I need adaptors and a interface?

Can anybody help?

Also, I am guessing as Logic only runs on MAC surely then they would not the best spec to recommend to run it?
I see all the upgrades as additional memory or a faster process?
Is a retina screen necessary, and why flash based storage against a 1TB hard drive, and a i5 instead of an i7
The main reason for this purchase is to play live and use backing tracks and record found sounds and make creative songs.
I hope you can provide some valuable feedback, as I am a longtime MAC user and see upgrades and changes happen regularly but the most important thing is the songs not the equipment.
I have £500 already and willing to add another 500 to 700 pounds, then software extra.

How can you change the font size in the application and system headers?

How can you change the font size in the application and system headers? I searched the system and finder prefs to no avail. Changing the screen density is not a good option.
Thanks

I downloaded Tinkertool. Found the font section and increased the size of most selections. The only thing that changed that I can see is the window label. The apple line, bookmarks line, the tool bar in safari are all the same---font size of about 4. Found the finder "show view options" but that didn't seem to change anything either. I'll keep working. Restarted all apps after changes as well.
