Recover RAID 5 array with new root drive

Ok, I have a root mirror and a 4 drive RAID 5 array on an E250. The linker got hosed on the root partition and mount fails as a result. I've tried repairing the linker to no avail. So I replaced c0t0d0 with a brand new drive and put a fresh install on it. The second half of the mirror is still there and can be mounted now. The question is how to I restore the RAID 5 array to get to that data without losing data on the RAID 5 array ?

Ok, here's what I got:
From the new, fresh, root partition c0t0d0s0 the first 6 lines are the old root mirror that I copied over:

Trying to setup RAID 1 with new SATA drives on xserve 2009 model

Trying to setup RAID 1 with new SATA drives on xserve 2009 model
I have an Xserve rack mount model Xserve 2.26 Quad Core (EMC# 2279) with an Apple RAID card, 24GB RAM (running 10.9 Server software)
Purchased two Western Digital 1TB SATA III 7200 RPM 64MB Cache Black WD1003FZEX drives
It came with three 160GB SATA drives. I'm leaving one of the original 160GB drives for the OS, but I want to replace the 2 other drives and set it up with RAID 1 (mirrored). I bought 2 brand new Western Digital 1TB SATA drives and formatted them on another Mac through Disk Utility with Mac OS Extended (Journaled) formatting. I then placed the new drives in the Xserve and booted it up. After I login it immediately gives me 2 error windows saying...
"Apple RAID Card
The Apple RAID Card installed in your system requires your attention."
It has two buttons underneath this message allowing me to either select 'Ignore' or 'Open RAID Utility'
I've tried to RAID the drives the Disk Utility and through the RAID Utility with no success.
I have both drives mounted on the desktop, as separate drives, but I really need to set these up as a RAID 1.
I've been reading other forums, where others have been able to get this to work by using a jumper on certain pins (5 & 6)of the drive to back down the transfer rate to 1.5 Gb per second. I tried that and it didn't work for me. Maybe I used the wrong pins -- I just don't know. I'm also wondering if there is some Apple firmware that is required on these drives? I'm asking for help from anyone who has gone through this same issue. Thanks in advance.

UPDATE -- I had an issue with the RAID card battery, it was dead and I have since replaced it. But I am still unable to setup the RAID 1 drive configuration. Does anyone know if it has something to do with the faster transfer rates on these new drives. Maybe they need to be clocked down with certain jumper settings on these Western Digital drives? Or am I fighting a losing battle because these drives don't have Apple firmware? Any help would be appreciated. Thanks.

Will Time Machine with Leopard Sync With New Hard Drive and Snow Leopard?

My computer is a 20" iMac that I bought in late 2008. The hard drive had trouble so Apple repaired with disk utility. Week later, more trouble so they did full hard drive erase. Data was backed up on Time Machine, 500GB also bought in 2008. After full hard drive erase, and reinstall of basic software, upon reboot, computer would power on then immediately off. It doesn't get past white screen. They advised a new hard drive install is needed.
A computer friend can install a hard drive just fine for me. However, I do not have the Leopard install disc. He could do it with Snow Leopard but I am scared. I'm afraid because my Time Machine last backup was with Leopard, not snow Leopard. I do not have my application discs with me, they are in storage in another state. Thus, if upon adding replacing hard drive and installing Snow Leopard my computer won't be able to sync FILES and APPLICATIONS from Time Machine because its on Leopard I will have a problem.
How can I either 1)Get a Leopard install disc and do that with the new hard drive install OR 2)make sure that a Snow Leopard install with new hard drive won't prevent my Time Machine from being able to install the saved FILES and APPLICATIONS if I don't have original APPLICATION (ie Aperture, Photoshop) with me? Thanks for any help you can provide.

Hi, and welcome to the forums.
That Mac should have come with Leopard. If so, call AppleCare. They'll send you replacement discs for a nominal fee.
Once this is sorted out, make a 8-10 GB partition on an external HD or your internal HD, and use the Restore tab of Disk Utility to copy the Install disc to that partition. Then you can boot and run from it instead of the physical disc. It will boot and run much faster, too.
He could do it with Snow Leopard but I am scared.
If he does, and doesn't provide a retail Snow Leopard disc, you must buy one ($29). It's a violation of the license to share software, and you'll need a SL disc to do things like restore a Snow Leopard backup, or the Snow Leopard Apple apps, or repair the internal HD.
Your best bet is to stay with Leopard, at least until you have access to your 3rd-party software discs.
What you can do, however, is borrow his Snow Leopard Install disc (assuming it's a white Retail disc, not a gray one that came with his Mac), and use it to do a full system restore from your backups. That's not a violation of the license, since you don't install or use OSX from that disc; you just use the Installer utility on it to restore the Leopard OSX and all your data from your backups.
See #14 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum), for details.

Can't recover software to Satellite L745-S4210 with new hard drive

Was using the laptop when it completely froze. Used power button to force shutdown. When restarted, hard drive was making a ticking noise and got this error message:
PXE-MOF: Exiting PXE ROM
No bootable device - insert boot disk and press any key.
Setup utility did not show the presence of a hard disk drive. Assumed that hard drive had gone back.
Purchased a new hard disk drive at MicroCenter. Toshiba 2.5-inch SATA 640GB drive, the same drive that came in the laptop from the factory. Also used the opportunity to upgrade RAM from 4MB to 8MB.
Installed new hard disk drive and new memory. Ordered the Recovery Disk set from Toshiba.
At startup, new hard drive doesn't tick. Setup utility sees a Toshiba hard disk drive. Got the "no bootable device" message. Inserted the first disk of the Recovery package and held down the C key, per instructions. System began to respond but then switched to Windows Boot Manager screen.
Here are the error messages:
File: \Boot\BCD
Status: 0xc00000e9
Info: An unexpected I/O error has occurred
Reseated both new hard drive and new RAM. Tried again with same result. Reinstalled old RAM. Tried again with same result.
Now at a wall. What has gone wrong? Is the new hard disk bad? Bigger problem. The unit is outside the factory warranty.
Any help is appreciated.

File: \Boot\BCD
Status: 0xc00000e9
Info: An unexpected I/O error has occurred
I don't understand how that could appear when you boot from a recovery disc with a new hard drive in place. It implies there is something on the drive.
0xc00000e9 "Boot\BCD" "unexpected I/O error "
Maybe try another drive?

Raid 1 with two external drives

Hi Everyone,
I've been searching for some answers on this and havent quite found what ive been looking for so i figured id just ask. I have two identical 1tb g-drives daisy chained and hooked up to my imac via Firewire 800. I want to make one of the drives raid 1 to mirror all the information on the other. What is the best way to go about doing this?
I was also wondering would it be better just to have time machine do backups of one drive onto the other? any advantages/disadvantages to either method?
Thanks in advance everyone!
Cheers,
Scott

These drives will be used to store Masters and dailies from photo and video shoots and well as the final edits from those shoots, so id qualify them as "mission critical".
Instead of "making" your own RAID1 array, you may want to investigate some "turn-key" RAID solutions. For example [this one at Macsales|http://eshop.macsales.com/shop/Mercury-EliteAL-Pro-RAID]. (That's just one RAID1 turn-key unit that Macsales has.)
Since you mention video, perhaps even consider RAID5 for more capacity, or RAID10 pr RAID0+1 for higher speeds. RAID0 would be good for the edits "scratch space", but not for any "real" storage. Thus the use of RAID10 or 0+1. (If you really want to get the max performance, do some research on the differences between 10 & 0+1.)
...Im now thinking however that i should have my masters in raid1 and on separate drives have my live edits being backed up by time machine as they change. Would this be a good thing to do?
Again, RAID1 is not a backup, so regardless of where you have the "masters", they should be backed up. With the backup, you can then recover from a loss of a drive, it will just be a little more time to get running again compared to RAID1. Thus the "need" for RAID1 is debatable for the masters and final edits, etc.
Also realize that RAID1 & RAID5 generally have slower performance than an individual drive (or RAID0) due to the overhead of writing the mirror or parity info. In many "workstations", they have a individual drive to boot from, then a RAID0 array for the editing "scratch space", and the final version of the file on some other storage. (i.e.: RAID5 SAN.)
Be careful with reliance on Time Machine for backups. Time Machine is good, but sometimes Time Machine can't backup files that are in use. (e.g.: [iPhoto|http://support.apple.com/kb/HT4116].) This is true of most backup systems unless you get some really expensive software so for something you're considering "mission critical" like these video files, I'd be looking at an additional backup system. (Even something as lowly as manually copying files to an external hard drive or an Automator workflow.)
To give another perspective: RAID1 if you absolutely can't have this system down for even one second. Which means your boot drive needs RAID1. Your "scratch space" on RAID0 or a SSD, since you want speed and can deal with the loss of a drive. Your "masters" & "final edits", you need to consider _+long term+_ storage. (a.k.a.: archiving.) The largest hard drives currently are 3TB. Being video, I'm going to guess you'll out grow this quickly. With RAID1, you'd be "stuck" at 3TB until larger hard drives come out...and then you've have to buy two of them...then be "stuck" again. So IMHO you should be looking at a RAID5 system that can grow. They can be "slower" RAID5 since you're looking at long term storage rather than max performance like the scratch disks. (If you need a little more performance, then RAID10, but you'd be sacrificing capacity.) For example, the 8 or 16 drive Drobo. Start with 2 or 3 drives now, then add more drives as needed. Drobo's of this capacity aren't cheap, but if they are as "mission critical" as you think they are, then a Drobo or similar is probably a worthwhile investment. But really, it appears to me that a proper backup procedure of your masters/final edits would be sufficient. RAID1 then is just icing-on-the-cake, albeit, very good icing.

Help with new Hard drive Please!!

HI
I have a K8n Neo that i have been running fine with a 80GB edie hard drive that has been running fine for the last 3 months.
But i decided to upgrade to a SATA hard drive ( Samsung 160gb spinpoint )
So i fitted the hard drive connected all ok!
But when i try to load windows xp pro i get a error!
It says:-
An error occurred while setup was updating partition information on:
131070 mb disk0 at id0 on bus0 on atapi [MBR] set-up cannot continue??
I do not think it can be the hard drive as this is the secound one that i have tried!
Can someone PLEASE help me before i go MAD!!
Lots of thanks
Numpty 69

numpty,
the following steps helped me to seamlessly migrate from IDE to a 160 GB SATA Maxtor.
First of all I hope you still have your old IDE HD set-up as a bootable device with OS installed. Unplug your SATA drive and revert to your old PATA drive as boot.
Second, shut down your computer, plug in your new SATA drive and follow this thread for single SATA drive set-up Single SATA or Multiple Drive Array Setup FAQ
save and exit BIOS, re-boot and enter BIOS again. You should now see your SATA drive in the boot order.
Except: I do not see from your specs whether you run XP with SP2. If not, you ran into the issue of the 128 GB limit and XP will not recognize your drive.
Do not set it as boot yet. For me, it even worked out to turn off SATA RAID again.
Third, boot OS from PATA drive. XP should now recognize your new SATA drive and start installing the SATA drivers (I used the nForce 5.10 and had no issues). Re-boot into OS, you should now see all drives with proper drivers installed in the hardware tab.
Fourth, get yourself a HD cloning tool. I used True Image 8.0 but there should be enough freeware cloning tools around, maybe even from the HD manufacturer itself and clone your old PATA drive to the new SATA.
Fifth, re-boot into BIOS and set the SATA drive as boot now. Save and exit BIOS, re-boot and XP should now be starting from the SATA drive.
Hope it works, I keep my fingers crossed

(Resolved) Windows 8 - Recovery Discs Do Not Work With New Hard Drive

Update:
I decided to buy drive cloaning software. I cloned my drive, that resolved the problem of installing the OS on the new drive. Too bad neither HP's Restore disc's or this support fourm could help with this issue.
Origional Post:
Product Name: HP Pavilion G4-2235DX
Product Number: C3Q50UAR#ABA
BIOS: Insyde F.26, 2/21/2013
Processor: AMD A6-4400M APU w/ Radeon HD Graphics, 2700 Mhz, 2 Core(s)
BIOS Mode: UEFI
SMBIOS Version: 2.7
RAM: 12GB
Operating System: Windows 8 - 64bit (6.2.9200 Build 9200)
Situation: I purchased this computer new as a refurbished model from a retail store. I created system restore discs after initial setup using the HP Recovery Media Creation Utility. This system has a 500 GB hard drive. I purchased a Western Digital 1 TB hard drive to upgrade the drive in this notebook. After swaping out the drives and trying to load the recovery onto the new 1TB hard drive in the same computer, an HP dialogue so states "This PC is not supported by the System Recovery Discs. You will not be able to continue to recover this system with these discs." It gives a code (doesn't call it an error code) 0110-C3150UQ43#ABA underneath and only option is okay, the system reboots and follows the same pattern again and again.
I have upgraded drives in the past on Vista and 7 the same way using self created HP recovery discs with no issue, I do know what i'm doing. I've seen discussion mentioning BIOS issues and other such problems. I did try updating the BIOS to the one on the HP Support page (2013-03-01 , Version:F.26, 7.76M) and the recovery discs still will not work. I found the CyberLink Recovery Discs Utility thread, however this solution/software has no support for Windows 8. I have tried to run the utility and it fails, tried with compatiabity and it failed. Why is this happening and what can be done to resolve this problem?
I tried using chat support but it won't let me get through to anyone, claiming my warranty is expired. I just bought this computer 3 days ago and was assured a 90 day warranty.
Please help, Thanks.

Hey Joe907,
Thanks so much for posting your experience and using the Forum. I came across this thread in my research for another thread. The information you provided helped me confirm my suspicions.
I wanted to mention to you, if you want, you can have this post marked as solved by hitting Reply to your original message and just post your update:

in the Reply and click Post. Then you'll have an "Accept as Solution" button on your second post. Click that "Accept as Solution" button on your second post and the thread will be marked as solved. By being marked as Solved, the thread will be much higher in Google search results and it will more likely to help others. Not sure if you're concerned about it, but you'll also get the credit for authoring a solution.
Also, I wanted to apologize for the customer service issues you had. I hope that everything is working well with the computer now. Of course, if it's not, let me know. I'll be glad to help in any way I can.
Information on the warranty:
Refurbished computers are often erroneously marked as out of warranty, but it is simple to fix, and a phone representative could have corrected that for you. All computers' warranty start dates begin on the day they leave the factory. HP knows that there will be a period where the computer will sit on a shelf (for days or months) at the retailer. With refurbished computers, their 90-day warranties begin on the day they are refurbished. HP has no way of knowing what date the customer will buy the computer so the warranty start date stays the same until the customer registers the computer providing the date of purchase for the warranty system to be updated. If the registration process fails for some reason (rare, but it happens), phone technical support has a process they can initiate to have the warranty corrected. They only need a copy of the receipt showing the date of purchase.
I hope this information helps! Please let me know if you have any questions and thanks again for you post!

Recovery discs do not work with new hard drive

Hi I have come here desperately seeking help as I am not too knowledgeable with the workings of computers and I have spent an incredible amount of time just trying to get my laptop to some level of functionality. I purchased a HP Envy and it had a corrupt hard drive which would not work from day one, laptop was new. After a year of constant pressure on HP they finally decided to replace it and let me choose any laptop so I went with the Beats Envy 14 as it was the best one offered from the selection. Low and behold the thing would not work properly from day one, again my brother who is much more of an expert said that there was definitely a hard drive issue so for the past 3 years I have put up with a computer that constantly crashes with BSOD, where I have lost data on numerous occasions (only so often I can back up), that I have had to constantly reset the thing using HP recovery discs, and that generally cannot cope when performing multiple tasks. HP are most certainly shocking builds from my experience. Then just last week the hard drive just craps itself and the laptop no longer will boot up. I took it to a guy to get it at leYst working again so he has installed a new hard drive but with an old version of Windows 7. I want to go back to the Windows version I was akin to on the HP recovery disk , and essentially have it all set up as before except for now having a workable hard drive however I get the message: "This computer is not supported by the System Recovery Discs.You will not be able to continue to recover this system with these discs.Error: 0100 - 3385 - 3078" I also tried out of interest to load my old Windows 7 disc I had and XP but had no success. Tried booting from startup etc and various things suggested on help forums. Please tell me I am not stuck with this version of windows. Whilst the discs included Windows 7 it was a totally different version, this home premium one is terrible. Any help/advice would be gratefully received. Thanks

no they were both 500gb. I read about that already, I heard about creating a partition for recovery etc but this is all a bit above me , as I said I am not very technical when it comes to the working of a computer. These discs worked perfectly before but now with the new hard drive will not load at all. I essentially hate the Windows Home Premium verions the guy who fixed it put on, whilst the discs had Windows 7 on them the icons were way smaller, the desktop neater, the buttons different, everything was a lot more modern and I was used to it. This version looks like something from the 90s, have to constantly adjust size of Mozilla when browsing as it is huge. I have my own version of Windows 7 on another disc but the hard drive will not let it load either........considering waiting for Windows 10 but again unsure if this new hard drive will even let that update Thanks

Help with new hard drive and data recovery

I have a macbook pro 13" from early 2011...last week the hard drive crashed and after a few hours at the genius bar had to got tekserv to recover my data and get a new hard drive and update to 8GB of Ram. When I got my macbook back I was given an external hard drive that had everything from my old hard drive saved by the users on the old hard drive. I was hoping I could just transfer the user over to the new hard drive but since I had to restart the computer as a new computer I am not able to just reassign my old profile as the new one on this laptop. Maybe I've done something wrong but at this point I transferred all my documents over, moved my music and pictures over but I have a few things I can't figure out that I'm hoping someone can help with.
1. Do emails that were in my mail program from both gmail and my verizon.net program get saved somewhere or do I have to just assume those were lost?
2. my iTunes library is now there but none of my playlists are there. Should those have been saved somewhere in my iTunes folder that I should see them? I'm concerned about syncing my iPhone or iPads to iTunes without those there.
thanks for the help.

SYNCING IPHONE AND ITUNES WITH NEW HARD DRIVE

My hard drive crashed on my mac book pro and I had to replace it with a new one. I'm trying to get new music onto my iphone that I purchased thru Itunes, but it is saying that only one computer can be used. This is the only computer that I used for the library, but now there is a new hard drive in it. Obviously I do not want to lose the music on my iphone and I'm curious how or if I can get around the message saying that if I want to sync to a new computer that it will erase the prior library. Please advice because I would like to update my iphone as soon as possible.

Connect the iPhone and choose Transfer Purchases from the dialog box which appears or the File menu in iTunes. Do NOT sync the iPhone until you've completed this task.

Time Machine takes very long time to back up with new large drive

I started using Time Machine on my 17" MBP about a month ago. I was using a 250 GB Samsung drive. When I discovered that TM will back up other external drives (I have several firewire pocket drives), I purchased a 500 GB Cavalry drive with USB 2.0 and eSATA connections. The first backup of my MBP drive (about 85 GB) took several hours (4-6?). I backed up one of my pocket drives (about 60 GB), which took 3-4 hours. Then, when I changed the back-up drive in Time Machine to the new 500 GB drive with the eSATA connection, I stopped it after an hour, because only 2 GB had been backed up. I erased the drive and restarted using the USB connection. It backed up 3 GB in an hour. So, now I'm back to using the original back-up drive. I've performed benchmark tests on all drives (the Samsung 250, Cavalry USB and eSATA 500 GB, and the MBP internal drive) with Xbench. The USB speeds on the Samsung and Cavalry drives came out about the same with a slight edge to the Cavalry drive. The eSATA connection with the Cavalry drive operated at over twice the speed of the USB connections and at about twice the speed of the MBP internal drive (which is a 1.5 Gb/s SATA drive). Basically, I can't figure out why Time Machine takes so incredibly long to back up when I switched to the new drive. Any ideas?
Jeff

It took me 20 hours to backup 32GB out of 65. I don't know why. Using carbon copy clone to download to another backup drive I did it perfectly in about 30 minutes. I expect that those appllications which show applicatiions are at fault and will try later getting rid of apps such as F-10 and pathfinderfor the first download. I have no idea why this is so slow. Everything is so slow.

MacBook Pro won't boot with new hard drive, but a different MacBook Pro will

So here are the details. My friend and I both have 13-inch Mid 2010 MacBook Pro's. Same processor and specs since they were purchased at the same time, but originally had 250 GB hard drives. His hard drive failed and needed a new one. Put a 500 GB Seagate Momentus 5400.6 in his computer, and tried using a flash drive with "Install OS X Mavericks" on it to install Mavericks on his new hard drive. No matter what, it wouldn't install. I finally was able to install OS X 10.9.4 on it by connecting the new hard drive to my computer with a USB hard drive enclosure. I put the hard drive back inside his computer and it wouldn't boot (stuck on the gray screen with apple logo and a spinning wheel). I then attached to the hard drive to his computer externally with the USB enclosure, and then it booted and worked perfectly.
So, it seemed like the problem was with something inside his computer, but then I switched our drives, and that doesn't seem to be the case anymore. I put my original hard drive into his computer, and his new hard drive into my computer, and they both booted and worked perfectly, so I have no idea why his computer will not boot with the new hard drive internally.
To summarize, his computer boots with: 1) new hard drive connected externally (won't work if it's internal), and 2) my hard drive internally
but my computer boots with: 1) new hard drive connected externally AND internally, and 2) my hard drive internally.
Both hard drives have OS X 10.9.4 installed
If anyone has any idea what's causing this and how to make his computer work with the new hard drive internally that would be greatly appreciated.

So after switching the internal SATA cables from each computer, now we have
His computer, with my SATA cable:
1) Worked with every hard drive!
My computer, with his SATA cable:
1) Works with 1 TB Toshiba hard drive
2) Works with 500 GB Seagate hard drive
3) Works with my original hard drive
4) Flashing folder with question mark with his old hard drive
So it turns out you were right! Definitely had something to do with the SATA cables. But it's still strange that mine was able to boot with all the hard drives except the one that was originally in his. So it seems like it was some combination of his SATA cable and something else, since when his SATA cable was in his computer only 1 hard drive (my original) worked, and when it was in my computer, 3 hard drives worked. But at least its working, and I'm just gonna keep our SATA cables switched since that seems to work out fine

My late 2012 mac mini boots slow with new ssd drive

So here is the situation. I purchased a 128gb ssd drive, installed it a usb enclosure, formatted it to Mac OS Extended (Journaled), cloned it with carbon copy cloner 3, used the option key during boot up and selected the ssd drive and it booted my mac mini and it functioned perfectly. I than tested it for dozens of reboots and it worked fine. I then took apart my mac mini and removed the original hard drive and installed the new ssd drive. When I boot to the ssd drive it still takes 47 to 53 seconds just like the old drive. Aren't ssd drives supposed to be a lot faster?
My solution or tip is as follows; The reason it takes so long to boot is because the mac mini doesn't know you replaced the old drive and it is looking for it during the boot process. Finally it can't find the drive so it boots to the ssd drive. All you have to do to correct this is click on "system preferences", select and click on "startup disk" and select your ssd drive and click on "restart". After these steps your mac mini will now boot in about 17 seconds. Issues solved.

Yes, my solution fixed the issue. I went from a 47 to 53 second boot time to a 17 second boot time. The ssd drive is significantly faster than the original drive that came with my late 2012 mac-mini. This is my first post and I wasn't sure how to post this as a tip. I have another tip regarding usb 3.0 hubs.

Permission issues with new hard drive

Apple installed a new hard drive on my fairly new (june2012) MBP. The only backup I had was the time machine backup from the old MBP that I originally migrated from. Apple said no worries - I can restore from that so I did.
Today I bought an iphone. (I was a hold out, I'm all things mac since the 80s except the phone). I went in to clean up my Contacts before syncing the new phone to my MBP and I couldn't delete and contacts or groups. So I did a "get info" on my contacts ap and it didn't even have (user/me) on the list as a user. I added myself, gave me the read and write" capability and still can't make the needed changes, deletions or anything in Contacts, so I decided to check permissions using Disk Utility. I repaired permissions, and just to be sure verified permissions again. What a lllloooonnnggg list of issues and nothing has changed. Hit "repair permisions again and it is taking f o r e v e r. Now I am Verifying Disk to see what it says. No problem. Verify Permissions again - did it faster, but still a bunch of problems found. Repaired permissions again - same old thing - says its repairing, but I seriously doubt it. Am I supposed to do this over and over again?
Suggestions???

Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Creating a mirrored raid set with a hard drive that already has data on it.

I have a hard drive that I keep my photos on, and want to create a mirrored raid set that includes this drive, with its data, and another drive. How can I do this without erasing the drive with my photos on them? I am running 10.7.5 if that matters.
Thanks for any help.

Creating a Mirrored RAID reformats the drive and loads a substantial RAID driver and some tables onto it. When completed, the drive is inherently a member of a RAID set, and will continue to be so even if moved to another Mac.
because of this, you cannot create a RAID directly on a standard drive that contains data already in any reasonable, risk-free way.
To amplify what The Hatter has said above, Mirrored RAID is not Backup. Mirrored RAID only increases mean time to repair to keep a drive failure from becoming a Data Disaster. You still need a Backup. Mirrored RAID does not protect you from deletions from user error, crazy software, or "just because".
I run a mirrored RAID in my Home Server, which contains all the Users files for everyone in the Household. And I also recognize (after being burned by it) that Mirrored RAID is helpful, but not a sufficient Backup by itself. I back up the Users Drive automatically to an External drive using Time Machine. [So what I am advising is not just theoretical, I am living what I am advising.]
With WD Black 1TB and other very good drives in the under US$100 range, there is really no reason NOT to invest in several drives for such an undertaking.
