How to restore a software raid mirror after a drive failure

i set up a software raid mirror with two hard drives in a mac pro. then one failed as reported by disk utility. i replaced the drive. it does not seem possible to restore this raid short of copying the files to a third location and then erasing and establishing a new raid. is there a way to simply "restore"?

Question: Do I need special software to administer the Mac Pro RAID Card or the Xserve RAID Card?
Answer: Normal administration can be carried out using the RAID Utility (found in /Application/Utilities) or by using the raidutil command. For more information refer to the User’s Guide or man raidutil.
The command-line utility should be available in Single-User mode.
To run RAID Utility, you may need to boot to an alternate source of Mac OS to be able to manipulate the Boot drive.
This article suggests using the Make Spare command:

How do I uninstall and reinstall CS3 after hard drive failure?

Hi. I suffered a recent hard drive failure on a Mac Pro. I didn't have a backup, like a dummy. The hard drive fails to boot so I installed OS on new blank hard drive and attempted to drag over whatever I could see and find from old drive onto the new one. I tried to start CS3 after doing this but it gives me an error: "LIcensing for this product has stopped working. You cannot use this product at this time. You must repair problem by uninstalling and reinstalling this product or contact IT Admin or Adobe Customer support" When I go to Utilities to find uninstall for Adobe the file is not there. WHen I try to reinstall from disk it says "setup error; setup has encountered an error and cannot continue. COntact Adobe Customer service support for assistance". I contacted them via chat and they told me they cannot help me and to post this issue here. Is there a way to resolve this? Am I just missing a file or something that will resolve the issue? Any help would be greatly appreciated. Thank you.

You can't install applications like that. Use the original disks to
install the software.

Restoring picture and movie files after hard drive failure and repair

I need some help restoring photo/movie files from my external hard drives after my iBook was repaired following a storm. I have backups hidden all over my external hard drives. I have unburned burn folders that may have pictures on them. I was using iPhoto from iLife 05 and iLife 08, and Kodak Easy Share. I have searched on spotlight using ".jpg", "pics", and ".mov" and titles of various images, but I am still missing images that I am fairly sure I duplicated to external hard drives. Any ideas for searching?

Thanks, I just downloaded EasyFind. I ran an initial search and it looked very effective. I will have to manually check the search results to see if it is getting any files I haven't already been able to find.

Problems restoring files with Time Machine after hard drive failure

Hello everyone,
I had a Mavericks (10.9.5) installation on my Mac Mini when my hard drive suddenly "died". I therefore replaced the hard drive with a new one and started the recovery mode using the cmd + R keyboard shortcut during booting. I then partitioned and formated the new hard drive and afterwards selectd "Restore from Time Machine Backup" (see the screenshot on the following page: https://www.apple.com/osx/recovery/). To my surprise, the following error message was displayed: "An error occurred while adding a recovery system to the destination disk". After some research, I discovered that this problem is probably caused by a Mountain Lion installation bug (http://macdailynews.com/2013/02/28/new-macs-suffering-from-os-x-mountain-lion-in stallation-bug/). This leads to my first question:
1) Why does the recovery mode start the Mountain Lion (10.8.5) installer and not the Mavericks (10.9.5) installer?
Anyway, since this problem left me no alternative, I selected "Reinstall OS X" instead, which downloaded Mountain Lion from the Internet. After the installation was complete, I used Migration Assistant to recover my two accounts, their apps and data. However, after the process was completed, I discovered that some files were missing in a folder that I was using before the hard drive "died". This leads to my second question:
2) Why are some files missing from that folder?
Anyway, I though I could quickly recover these lost files by entering Time Machine. I did that and selected the respective folder. However, having that folder or any other folder selected, Time Machine doesn't display any previous back-ups on its timeline although the latter goes back as far as 26 August 2013.
3) Why doesn't Time Machine display older versions of that folder on its timeline?
I will greatly appreciate any help!

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.

Unable to rebuild in mirrored RAID after hard drive failure

I plan on getting a mirrored raid setup for my backups of all my work that I have done. I am currently testing out how the built in software RAID works in OSX.
I have setup a mirrored RAID with two flash drives and it works fine, i then tried to simulate if one of the disks were to fail by reformatting it, and then i tried to plug it back in to rebuild it, but it does not allow me to do so the rebuild button is greyed out. Could it be because i had the RAID setup as automatically rebuild? If someone could walk me through the process of rebuilding the raid setup that would be great, i would like to figure this out before purchasing the harddrives.

Awesome, this just saved my sanity, thank you!
I was about to go totally insane when I couldn't find the option to add a new drive to the existing RAID mirror and then rebuild the whole thing.
In the Apple help, it just says "go to RAID" "click rebuild" - but this is absolutely not how it works!
Adding the new, empty drive by drag and drop wasn't mentioned anywhere - in addition to that I have never seen a program that has certain functions which can only be accessed by drag and drop.
Also the hard disk utility doesn't look like drag and drop GUI at all.
It was really easy as soon as I read this thread, so thanks again, this totally saved my day!

How to restore files from Time Machine after Clean Install of Mavericks

How to restore files from Time Machine after Clean Install of Mavericks. I know the data is there but seems unaccessable because I may have changed the Computer or Owner name. Is there any way to fix that now?

Hi Linc,
my back-up data is managed by Time Machine; the actual data is on a second internal Hard Drive with a capacity of 1TB - not partitioned. I am using Time Machine and have access to all data backed up since Mavericks Clean Install but not the data prior to this date.
When I open the 1TB drive in Finder I can see a folder "Backups.backupdb/Sigi's Mac Pro/ followed by many folders of backup dates going back to 2010-09-20-103441 and up to 2014-02-07-142414 all followed with folder Macintosh HD. February 7th 2014 was the date of the clean install.
These Backups are followed by backup date folder 2014-02-08-075554 with a subfolder of MacPro-320GB (this is the name I assigned to my Boot Drive during formatting; I suspect I should have assigned the same name as before ie. Macintosh HD) and 2014-02-11 with a subfolder Macintosh HD, these are the ones I get access to by way of Time Machine > Restore.
Weird thing is on Febr 11 when I relised my possible mistake and renamed the Bootdrive back to what it was initially ie. Macintosh HD despite this I have access to all backup data since the Clean Install in both folders MacPro-320GB as well as Macintosh HD but not to any data prior to the Clean Install.
Is there something that Time Machine knows and prevents access or is it simply a matter of renaming the subfolder 2014-02-08-07554/MacPro-320GB to ........./Macintosh HD?
I like to restore selectively and not everything - It was hard work reinstalling apps that were supposed to be the troublemakers (ref my discussion on Maverick problems) but I now need to get onto data specific to some of these apps as well as other data I may have missed. Long story? Yes and sorry.

Got new miniMac servers with 2x750GB drives. How to setup and confirm RAID mirror?

Literally just got shiny new miniMac Server with the dual 70GB internakky hard drives/disks with
OS X 10.7.$ LION pre-installed. What a nice machine in a super cool box!
Seemed to bootup and run fine!
Now my issue (there will be more for this MAC newbie):
A. How to setup AND more importantly (item B below) CONFIRM that a RAID MIRROR is working?
Want nothing fancier than 2-nd drive is exact duplicate of 1-st drive at all times.
That is, an 'active and full up-to -the second" backup of the main 1-st drive.
I have done nothing to 1-st drive as it came from APPLE.
When I try to setup RAID set using DISK Utility, I get message about system(1-st drive) can't be used in a RAID or such.
yet I can add 2-nd drive to what I tink is a RAID set and then 'Enable' it.
It seems to add another entry to thr left-side of drves list panel but not sure that 1-st and 2-nd drives are BOTH in the new
"RAID SET' or that the set just consists of the "single" 2-nd disk?
B. I don't think that 1-st drive data is actually being duplicated to 2-nd drive.
For instance, how do I know that it was 'caught up' to match 1-st drive AND then is
staying caught up?
C. A 'RAID UTILITY' Icon brings up a not-available message, but I think that is because I don't
have HARDWARE RAID controller, just software RAID, correct?
D. What is 'Time Machine' and how does it play into this? I do assume that somehow/someway I need to
have off-machine backups also to be truly protected? How would a 2-nd identical miniMAC server be best
deployed to back each other up, in addition to their own internal RAID-ed disks that items above address?
My whole point of buying 2x750GB disks was to have mirror RAID set and
(foolishly) assumed that factory would set it up that way.
Please help me get setup right so when the inevitable crash happens,
I have some chance of recovering from it.

A. What are you adding to the RAID: a partition or a hard drive? You can only add hard drives to a RAID. RAID Utility should confirm that your RAID is working
B. No, I don't think so
C. It's because you haven't got RAID hardware.
D. Time Machine is a backup system in external drives. If you want, you can do backups in a external hard drive.

Re: Unable to rebuild in mirrored RAID after hard drive failure BOOTCAMP

CHRIIIIIIIS!!!
Problem!
first off, you're a genius. thanks for helping everyone around here.
Second.
I just installed Mavericks on my MacBook Pro 2012, and it broke Bootcamp.
I have a 750GB hard drive and it has 2 partitions, on for Mac and one for BootCamp, nice and simple.
When I open Disk Utility I get this....
It really broke the partition, it used to be named "BOOTCAMP"
Any help would be appreciated and yes i know how to use terminal, if that helps you.

Error 1015: This error is typically caused by attempts to downgrade the iPhone, iPad, or iPod touch's software. This can occur when you attempt to restore using an older .ipsw file. Downgrading to a previous version is not supported. To resolve this issue, attempt to restore with the latest iPhone, iPad, or iPod touch software available from Apple. This error can also occur when an unauthorized modification of the iOS has occurred and you are now trying to restore to an authorized, default state.

How to restore my 2 mail acc. after incorrectly moving back .plist file ?

This morning my Mail was quitting 5 sec. every time time I opened it. I moved com.apple.mail.plist file to trash, started Mail. I got a message that one of my mail boxes(don't remember which one..) will be renamed.
I guess I made a mistake by opening Mail and not Mail.app ?
Closed Mail and moved back .plist file into Library/Pref.
Here I made another mistake by dragging incorrectly, it was placed into some other program. I deleted the other program, and moved the .plist into Library/Prefer.
As the result, my both Mail accounts are gone, and instead I have now MobileMe in my Inbox.
How to restore my accounts now please ???
Thanks!!!

I have both POP accounts in Library/Mail. What should I do to have both POP in the Mail ?
To drag both to desktop and then to Mail? how and exactly where ?
or to create these two POP again in Mail and then drag both POP folders there ?

How to recover entire OS X system after entire drive deletion without a backup?

My ENTIRE hard drive was deleted, and I need to know how to restore the operating system and all of my files. I am desperate! Years and years of photos were on the drive, as well as very very important files and applications. I really need to get my files back! Is there a way to restore the OS and get all of my files back? Please help me! What are my options?
And also my Windows 7 partition was deleted as well, so if I could get that back too, that would be nice, but most importantly is the Mac system and all the files.
And if you all want to know how my drive was deleted, I'm not sure, just deleted a partition in disk utility, and restarted and the whole hard drive was deleted, but I don't care. I just need my files and operating systems back.
Please help me!

Well, you said you don't have a backup? Whatever was deleted - it is gone unless you try to use a disk recovery software and/or service. Some of these tend to be rather expensive and, if that is what you want to do, then do not use the Mac at all because any use will overwrite the areas where your files have left some traces. You can try something like Data Rescue:
http://www.prosoftengineering.com/
It may or may not work. The OS is easy to replace - just pop in your original install disk, boot from it, and install the OS. After that, you can update via Software Update. Your files, however, may be lost unless you can recover some of them.
I cannot address Windows since I do not run Windows.

Restoration after Hard Drive Failure

Hello all.
My Powerbook G4 suffered a hard drive failure a couple of months ago, and every bit of information was lost in no-man's land. After seeking help with Apple, I was sent to DriveSavers. Thankfully, they were able to recover 100% of my drive or that's what they tell me anyway. (No need to scold me, I have learned my lesson about backing up EVERYTHING -- especially when the bill arrived from DriveSavers!) The Powerbook was kaput, so I decided to purchase an new iMac. DriveSavers has put my entire Powerbook contents onto several DVD discs, but so far I have had very little luck with actually transferring and using any of it on the iMac. I have been able to copy document files from Appleworks, Photoshop, etc. onto the iMac, and I can open them and use them with no problem. Although, I did have to go back and re-install the actual Photoshop and Appleworks applications from their original software discs since I was unable to successfully copy the applications from the DriveSavers discs onto the iMac. Still, I am in desperate need of certain Apple applications from the Powerbook that just will not appear on the iMac -- things like Address Book, all of my Stickies , plus the other Stickies that were only located on Dashboard (i was a stickies freak), the emails and contacts saved in Mail, the appts. & scheduling in iCal, etc. I cannot successfully access these kinds of things. I am able to copy an entire disc from DriveSavers onto the iMac, but when I launch the Address Book application from that folder, it just opens up the empty, brand new Address Book from the iMac or the new, empty iCal. The same thing happens with other similar programs. (I think iTunes has been the only thing with which I have any kind of success.) I've even rifled through the DVD discs and gone through my old User folder to the Library folder, then the Caches folder, and finally to the .com.apple.AddressBook folder where I extracted just the Metadata folder which clearly contains all of my contacts. When I try to add just the contact cards to the iMac's Address Book application, I still doesn't work and remains empty. The only way I've been able to look at any of my contacts is to use TextEdit to open those contact cards, and then dig through all of the jargon and piece together the info. It's very frustrating and time-consuming. I would just like for my Powerbook to be reincarnated, if you will, here on this new iMac. Is this even possible? I am completely baffled, and beginning to fear that I may have paid thousands of dollars for DVDs that would serve me better if I were lost in the Sahara and needing to signal a plane flying overhead by reflecting them against the sun. If anyone has any advice or tips, I would be very grateful.
Cheers,

How to restore my backup in laptop from external drive

How to restore my backup in my macbookpro from external drive

Hello Jayrajjpatel,
It sounds like you have a Time Machine backup on an external drive that you would like to use to restore your computer. The following article will help you get that done, named:
OS X Mavericks: Recover your entire system
http://support.apple.com/kb/PH14185
If you’re restoring your system because of a problem with your startup disk, repair or replace the disk before following these instructions.
Make sure your Time Machine backup disk is connected and turned on. If your disk is on a network, make sure your Mac is on the same network.
Choose Apple menu > Restart. Once your Mac restarts (and the gray screen appears), hold down the Command (⌘) and R keys.
Select “Restore from a Time Machine Backup,” then click Continue.
Do one of the following:
External backup disk: Select it, then click Continue.
Time Capsule: Choose your network from the AirPort menu on the right side of the menu bar, and then select your Time Capsule and click “Connect to Remote Disk.”
Network backup disk: Select it, then click “Connect to Remote Disk.”
If necessary, enter the name and password you use to connect to your backup disk, then click Connect.
Select the date and time of the backup you want to restore, then follow the onscreen instructions.
After you restore your system, Time Machine may perform a full backup at the next scheduled backup time. This is normal. Time Machine resumes incremental backups after the full backup is completed.
Thank you for using Apple Support Communities.
All the very best,
Sterling

Problems stting up RAID (Mirror) for boot drive.

I have a Mac that I want to setup mirroring on the boot drive (it's running Mac OS X Server and once I get everything going I need to minimize downtime).
Since you can't move a drive with data into a raid set I first cloned the boot drive to a 3rd drive, booted off that drive, then set the two 80gb drives up as a mirror. after cloning the data from drive #3 back to the now mirrored pair I can't boot off the mirror.
I've tried using both the Startup Disk preferences and also the bless command to mark the raid as the device I want to boot from but it doesn't recognize it as a bootable device.
What do I need to do to make the raid bootable?
thanks,
Bill

The drive I want to boot off (the mirror) is "Macintosh HD"
The temporary drive it's running on now is "Macintosh HD 0"
Both drives show up in the startup items preference panel, I have "Macintosh HD" selected. When I hit restart it fails to recognize it as bootable and fails back to the other one.
I'm not sure which folder you want the permissions set on. Here's what it looks like right now.
