Disk Repair For A DYI Fusion

About 4 months ago I purchased a solid state drive and installed it with a regular drive (installed where the optical drive was originally located) in a Macbook Pro OS 10.8.4, 2.8 ghz i7 Core. I followed directions provided by Other World Computing and created a fusion drive using the two disks. Everything has been working great and the fusion is smokin fast.
Prior to the fusion installation I always ran the disk utility or disk warror to look for little glitches on my drive. The issue is when I boot from the recovery disk or a usb startup the two drives are shown seperately rather than one fusion drive.
So the question is can I run disk repair on each of the disks seperately without harming my fusion setup, or is there some other way to have a repair utility to recogonize the fusion set up on the two disks.
I am not having major issues but in the past found that doing a check like this can be helpful.

Have you updated DiskWarrior to 4.4? According to the Alsoft site, it as compatible with Fusion Drives:

Disk repair for external hard drive

Hi, I gave my son an external hard drive to back up his school work, besides the normal backups of on the Time Capsule. So how he managed to hget the external hard dirve disappear from the screen while there is no back up left on the TC.
I have tried disk utility an number of time on several computers to get the External hard drive working. No luck there. I have tried restore in disk utility, but I cannot get the source and destination righty for a reason.
I have read an advice of Francine Schwieder dating back to 2007 where she advised to run terminator, this is the result I get while the xternal hard drive was connected to my Imac.

With my limited knowledge, was a partition placed on this external hard drive ? I cannot see or acces the external hard drive.
Is there anyone who can help me with this ?
Hope to hear from you.

If you wan to give Data Rescue 3 a spin (I'm testing it out now for the first time) you can get it - and a number of other apps - for $50 from MacUpdate's December Bundle.
Because I have redundant backups, I've never used either DiskWarrior or Data Rescue 3 - but I wanted to try it so that I will be able to know how well it works (or doesn't).

Directory Damage, what can be used for Disk Repair and Virus Detection?

Hi,
My eMac is acting up. Yesterday I started getting these messages that I needed to restart my computer (message was in a brown box window with an icon of a start up button in background).
I did the disk repair using Start up CD and it came back with "invalid key......." or something like that, and when I tried to repair it, it tried to repair the B-Tree's but then said it could not repair the problem.
I have Diskwarrior 3.03 Build 39, on a CD and on my FW Ext HD, which has a clone of my Mac HD.
Diskwarrior could not produce a graph of Mac HD because the directory was damaged. When I did a rebuild it hung on step 9 comparing directories, said there was 7 million + tests. ( I let it hang on step 9 for 15 hrs. to see if maybe it was just taking a long time due to corrupt directory). I finally clicked on Skip and got to the report page. I could do a preview, but the replace button is greyed out. When I was comparing the sizes of each folder, in both preview and original, I got a can not calculate error message on a few of them. The size of Mac HD in preview compared to the one in Original was different by 4 gbs. A week ago I repaired the Mac HD and did a Diskwarrior directory repair on all my HD's.
Before I do any reformatting of HD or other drastic measures, I was wondering what is safe to use for disk repair and virus detection. I know there is Norton System Works 3.0, Norton AntiVirus and TechTool, are these the only ones? Are these safe to use? Are there any other programs that can repair directory damage?
Thank you in advance,
Deb

The long-standing rule of thimb has been that if Disk Warrior can't repair a mungled disk directory, then you're looking at reformatting or replacing the hard drive. Since this is a week-old hard drive, I'd suspect the replacement hard drive is itself bad. It might save you grief in the long run to contact the vendor who sold you the drive and inquire about their warrenty. You might want to first run the file system check utility fsck as described in Using Disk Utility and fsck
Directory repair and antivirus protection are different critters. Norton AV is mostly safe (if you don't mind it's track record of false positives) and is used by the IT department at the lab where I work. Norton SystemWorks, AKA Disk Doctor Kervorkian, is most assuredly NOT safe. For every poster reporting something nice about it, you'll find at least 2 dozen cursing it. It has a known track record of detecting problems no other utility finds and of "repairing" drives such that nothing can then read or repair the drive short of low-level reformatting (and occasionally even that fails).
Tech Tool Pro 4 has a good reputation, as does Drive Genius. Tiger OS X 10.4.2 and later include a version of Disk Utility that can for the first time also make effective B-tree and keys out of order and overlapped extent repairs. Still, my personal gut feeling is that if Disk Warrior is choking on the hard drive, you're looking at reformatring while zeros the drive (zeroing should detect and map out bad physical secotrs).
You can also refer to Disk First Aid: What to do when it finds an error and to Handling "overlapped extent allocation" errors reported by Disk Utility or fsck

HT3275 I am using an external drive for backup. I am now getting a message that the drive needs a disk repair, but when I run disk repair it just seems to freeze.

I am using an external drive for back up. Yesterday the backup failed and I received a message that the external drive( a passport drive) needed a 'disk repair", when I ran disk repair nothing happened it seemed to freeze. Suggestions? should i simply erase the external drive and start over-my computer is fine.

Get a different drive for backup.
In the meantime, once you are backed up some drive safe, then you can attempt to repair the backup drive using the repair the directory link.

Weird Disk Repair warning for backup drive

I used to run Time Machine and Silver Keeper (Lacie software that came with my 2TB backup drive). Both backed up to separate partitions. Yesterday I decided to stick with Time Machine only. So I deleted the Silver Keeper's partition and then extended Time Machine's partition for all of the drive. I used Disk Utility to do this.
This morning, when I turned my computer on, I got this error after starting up:
"Disk Repair
The disk "2TB-TM" was not repairable by this computer. It is being made available to you with limited functionality. You must back up your data and reformat the disk as soon as possible."
Well, I was able see the drive on the Desktop and access all the backup files--until running Disk Utility. TechTool Deluxe does not see the drive. But Disk Utility does see the drive. But the Verify/Repair Permissions is greyed-out. When I click the Verify and Repair Disk buttons, I get this error (in bold red letters):
Invalid record count
Volume check failed.
Error: Filesystem verify or repair failed.
I can reformat this drive as it recommends. But I'd rather not if it's a simple fix. Any suggestions?

OK, I'll reformat. I'm assuming that will fix the problem and my drive will be back to its normal self. I also assume that I messed it up with that repartitioning. Do I need to worry about my drive being broken or replaced?
that's hard to say now. reformat and see what happens.

Attempt to install Mountain Lion has highlighted need for internal disk repair. Even after "repair" ML still says disk is damaged. Attempt to restore from Time Machine back-up failed - cannot 'see' internal HD to restore to. Help! Has attempt to install ML caused these problems or just highlighted existing need to Repair Disk? Even so, why can back-up from Time Machine not see the internal drive to restore to?

Csound1, William & Sig .... thanks for taking the trouble to reply. I fear you are right - I'll need a new disk. I'm booked in at the Apple Genius Bar in Bordeaux, France on Wed ... quite a challenge as my French isn't great! The current internal disk is 500gb, does anyone know whether I can upgrade my 21.5" iMac (circa Oct-2009 vintage) to a larger size internal disk, 1Tb or even 2Tb? I already have one external 2Tb drive and another one on order (I have masses of media stored and more planned as I've just taken up photography). Seems a bit of a pain managing with only 500gb internal storage. OR, can you advise me on how I can store all my photos on my new 2Tb external drive - I can't seem to figure out how to set the path for iPhoto to see them (I can't even figure out where they are stored right now!). Same with iTunes, how do I set the default storage to the external drive (I moved everything manually and then imported them all from the new drive - it worked but seemed very convoluted). Any advice on how to manage multiple drives gratefully received. And thanks again for previous replies.

Lost Option For Disk Repair Permissions

Hi Gang
I'm using 10.4.11
Unless I'm missing something here, it seems I've lost the option to Repair Disk Permissions for all of my
Non-System Drives? I now only have the option to Repair Disk Permissions for the System Drive only.
I never had this condition before - always ran Repair Disk Permissions for all the external drives on a regular basis. Perhaps this process was never necessary to begin with? But that still doesn't explain why the option is 'Grayed Out'
What have I done differently? The only thing I can think of, is the fact that I added an 800 FW cable internally (to the 3rd internal FW800 Out Port), on one if the PCI Multi Port Cards. That additional Drive is turned off right now.
Screen Shots;
http://www.locationstudio.net/YesRepair.jpg
http://www.locationstudio.net/NoRepair-1.jpg
http://www.locationstudio.net/NoRepair-2.jpg
Yes I realize I have a lot of external drives, but I'd rather not get into a discussion of SATA Controller Cards at this point. I've got tons of Video Files that would ALL need reconnection in FCP. Trust me, it's not an option right now.
I'm just looking for an opinion about the loss of that Option to 'Repair Disk Permissions'
Thanx
Mike

And you mean, therefore, only SYSTEM Disks can have 'Repair Disk Permissions' performed? Correct?
Correct.
If so, then why was I able to see that function before? 'Repair Disk Permissions' was ALWAYS there despite the circumstances. Ummm?
Did you ever clone your internal to these before? It really should not be available unless there is an OSX on it.
How bout 'Disk Repair'? Does it benefit to perform this function on all of these external drives? I've always read this before.
Actually, THE most important one is Disk Repair, and it really should be done before any Permission Repairs... now it's not a problem to Repair Permissions if the Disk is OK, but Repairing Permissions if the Disk Directory is the slightest messed up is like sending envelopes of cash out to addresses, but all the street signs have been changed.
Just to see if it would make a difference, I checked the Box 'Ignor Disk Permissions' Same result - can only perform 'Disk Repair'
Yes, the way it should be, but normally you want Ignore permission set on external drives. You can have or set Permissions on external drives, but it's normally not needed.
BTW, Repair Permissions does not Repair all Permissions on your Boot Drive either, just on System Files/Folders, not any in your Users folder for instance.

Disk repair failed / should I reformat my drive / how to format and restore

I have a MacBook Pro late 2011 model and upgraded to Yosemite. The performance on my MB is ok, but just out of curiousity I ran a disk verify, and was told I needed to reboot, hold down CMD / R and run disk repair. I did so and the repair failed. I was promoted to backup and reformat/restore.
Now, I do backup everything using time machine (not sure though if Parallels image is backed up). I do not however have any install disks for Mac OS.
My questions:
1. Should I even bother reformatting my HD?
2. How do I go about formatting the HD and then re-installing the OS and all of my apps, particularly given that I have no DVD
Any thoughts are appreciated. Thank you

If you have extra external HDD, make clone backup with Carbon Copy Cloner or SuperDuper!, then,
1) boot from external clone backup drive.
2) reformat internal HDD.
3) restore from clone backup drive with Carbon Copy Cloner or SuperDuper!.

Need disk repair help fast!

My internal CD drive broke so I bought an external one. Problem is that the computer is in need of serious Norton repair and when using the Sony external CD/DVD drive to run the Norton disk the computer does not recognize the hard drive so I can't repair anything. In other words, I put in the Norton cd and it shows up just fine on the desktop but when Norton opens up and I am supposed to choose a disk to repair nothing shows up to choose from. Nothing at all, just a big blank space. The external drive works because I've burned from it although when I try to burn directly from, say iTunes, it goes to the origional disk drive which is broken so I have to use the toast light program to burn. Maybe there is someway I can make my external drive the default one? It is taking forever to load each program and I'm feeling doom with the way the computer has been acting lately and I really can't afford to be without it as I run my business from it. thanks

Hi again, Donna,
Happy to hear you got rid of Norton!
You say your Mac has not panicked since you got rid of Norton, right? If so, you may have already fixed the kernel panic problem. I have not had a single kernel panic since I uninstalled Norton years ago.
If you do experience another kernel panic, the advice about kernel panics that you got from mrtotes is about the best that most Mac users can do for themselves. As explained in those suggestions, kernel panics are often hardware related. Be sure to disconnect all external devices that are not absolutely necessary when checking for and attempting to solve kernel panics.
You should not need to take your Mac to an Apple Service Technician for kernel panics if you can fix it yourself with the advice you have already been given.
<hr width="85%">
Next issue: You mention that your Mac runs slow (the beach ball spins for a long time.)
If you multiple applications running, close all but one and see if the problem goes away. If so, you may just be working your Mac too hard. Run fewer apps at a time.
If you have any external devices, including your external CD/DVD drive, connected, unhook them all and check to see if the beach ball goes away. If so, one or more of your devices may be the source of the problem. You can find which by reconnecting only one at a time and then checking to find whether the beach ball comes back. If no one device causes the beach-ball to reappear, try connecting two at once to see if any of your external devices might be conflicting with each other.
Your Mac may need basic Mac OS X maintenance. You have already done a Safe Boot, (and perhaps a disk repair), so try a permissions repair next.
Unless you have set the slider for your computer to "Never" sleep in System Preferences > Energy Saver > Sleep, you should also force background maintenance tasks as explained in
http://docs.info.apple.com/article.html?artnum=107388
The article lists several equally effective ways you can do this, I personally use MacJanitor, which is free and very simple to use.
FileVault slows disk operation and adds processor tasks to your Mac. If you have enabled FileVault, turn it off (turning FileVault off can take a while) to see if your beach-ball problem goes away.
One other thing that can cause slow (beach-ball) operation is that your startup disk may be too full. Check free (Available) space with Finder > File > Get Info. If you do not have at least 10 GB of free space, try Increasing available space on your hard disk.
For more comprehensive suggestions on OS X Maintenance, see Gulliver's
http://discussions.apple.com/thread.jspa?threadID=122021
Let us know how it goes.

How do I access Disk Utility for 10.7.1?

How do I access Disk Utility for 10.7.1? I found it in the forums a few weeks ago, used it, then lost the directions. This is a last ditch attempt
to use OS Lion. I parted my hair incorrectly when I installed and have been plagued by the dread rainbow spinning ball in EVERY application. Yes, every. Name one, Safari, Firefox, Text Edit, Mail, Excel, Word, iTunes, Garage Band, Calculator, Calender, iPhoto....yes, every, and I cannot
find a solution that works. I have back up files on two different hard drives 500 gig and 1 terrabyte with all my music, photo and writing files.
I am a writer and a musician so imagine the frustration. OS 10.6 is an option of course. My dedication to Apple and each new OS is deep so
I am hoping that somehow there will a fix, an upgrade, something that does not require me to go bac to the much more endangered species named OS.
hahhaa! Just stalled waiting for the ball to finish with it's random spinning.... SO, this is like a last desperate .... it just did two more stalls.
NO OTHER apps running, just little Firefox holding on for dear life, last desperate request for a fix.
MacKeeper has been great in sending helpful directions for getting the Antivirus to work after it mysteriously decided to stop working, Quite MacKeeper, go to Activity Monitor, force quit helper, start up MacKeeper and run program. It works!
SO before my third stall stops me, please post directions to open disk utility in administration mode so that I can do any further repairs that have not worked by using it from the open system. Also keychain synching stopped working with Lion.
Thanks to any and all who can help.

Press and hold Command-R keys and reboot. You'll then start up in the Lion Recovery HD. You'll find Disk Utility there.
Command-R to the rescue.
Just hold down Command-R during startup and Lion Recovery springs into action. It lets you choose from common utilities: You can run Disk Utility to check or repair your hard drive, erase your hard drive and reinstall a fresh copy of Lion, or restore your Mac from a Time Machine backup. You can even use Safari to get help from Apple Support online. And if Lion Recovery encounters problems, it will automatically connect to Apple over the Internet.

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

External hard drive won't mount, even after disk repair.

My Toshiba external hard drive won't mount on my MacBook Pro 10.8.5. I can see it in my disk repair, and when I repair, "the partition map appears to be ok." But I can't access the icon to be able to open the hard drive contents on my desktop. Help!

Hello maccynicwhoalwayshasmacs,
Thanks for the question. After reviewing your post, it sounds like trouble with an external HD mounting. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

Disk repair 'failed'

when i tried to repair my internal HD, disk repair fails. it found out that 'Reserved fields in the catalog record have incorrect data' do I need to format the drive and reinstall 10.4.11, or can this be fixed?

You could do that, but a simple reformat may not fix the low-level
issue that may exist on the hard disk drive; while a zero-overwrite
option Disk Utility provides may help, & also will defragment HDDs.
Of course, there is a chance a third-party disk utility could be able
to attempt and be successful in a repair where the native OS X
Disk Utility may not be fully adapted to these kinds of cures. For
some kinds of issues, Disk Warrior has been proven worthwhile;
so has (in some instances) Drive Genius, and TechTool Pro. The
version of these third-party disk tools has to match and be made
for the OS X version the repair is being done on.
There are times where a third party disk utility may make the
matter worse, so you have to really be ready and it does help
to have previous experience with the tools & how they work.
A crash course is never an expected way to learn, it happens.
If the computer is getting old, you may end up replacing the
hard disk drive, as they do wear out and work hard in a
portable computer. The cost per GB has come way down.
There are times when a hard disk drive is not readable and
the computer won't start from it, yet data may be recovered
from it in a few ways; one of them is FireWire Target Disk
Mode. Another may be to put the failed disk in an external
enclosure and attempt a repair at a later time, and have a
good hard disk drive in your computer.
If you backup your computer's contents and get comfortable
in making clones and using utilities, that is a good path to know.
In any event...
Good luck & happy computing!

Disk Repair Failure

I have an imac G4 15" Flat Panel 800 MGhz and I have been told that my hard drive went bad so i am about to install a new one. I probably should anyway, the upgrade will be nice. I hope. Anyway, I am trying to learn all I can from this experience so I have another question.
I was getting a grey screen with a folder icon with a flashing question mark on it so I did a disk repair and got this error message "Disk Utility stopped repairing "Untitled 1" because the following error was encountered: The underlying task reported failure on exit.
I then restarted the computer with my OSX Install Disk inserted and held down the shift key and the screen had the following on it:

After this happened I connected a imac G3 to my imac G4 with a Fire Wire Cable hoping to target my files and recover them. Then this message came up:
Inserted a disk containing no volumes that OSX can read.
So what does this mean?
If my Hard Drive is ruined can I recover my files?
I know there are some geniuses out there so I will await your reply.

First, check your SMART status of the drive with Disk Utility. If SMART is not verified, you should get another drive before you start loosing data.
When I got similar disk and 'underlying task' errors, I re-formatted the drive and that removed the errors.
I backed up my data to an external firewire drive of the same capacity by booting my PB off my Tiger install CD (the 10.3 should work too) with the firewire drive attached.
Select Disk Utility from one of the menus after you booted off the CD. In Disk Utility, select the Restore tab. Drag your internal PB drive into the source field, and drag your FW drive as the dest field. You will want to erase the destination. Just be careful to get the source and dest disks straight! Click restore and your PB HD will be copied over to your external. You might want to boot from your external to make sure it comes up and looks like it would from the internal drive.
Once this is complete, use Disk Utility to erase your internal drive. Verify your disk to make sure all the problems are gone.
Then run Restore again, this time using your external drive as the source, and the internal as the destination. When restore is complete, your PB will be bootable with all your stuff. Plus, you just made a full backup on your external drive!

Error in Disk Repair - PLS HELP

Dear All,
I have posted a message a week ago, about Error in Verifying Permission and Onyx Error -1. Then ~Bee (thanks for the suggestion, really appreciate it) replied and suggested me to try Disk Repair. I tried it this morning and the result was not very promising.
Below are the message:
Verify and Repair disk "Rich's HD"
Checking HPS Plus volumn.
Checking Extends Overflow file.
Checking Catalog file.
Invalid node structure
Volume check failed
Error: The underlying task reported failure on exit.
1 HFS volume checked
1 volume could not be repaired because of an error.
<--end of message-->
I also tried to verify Permission and it ran until 85% and it stopped without any activity until I 'stopped' the verification.
I really hope my HD is not up to something bad. What I have done were only installed CS3 (only installed Photoshop and Illustrator) and it was running fine until recently.
If anyone has any idea or suggestion, please let me know.
Thanks a lot!
Worried,
chityc.

The reason you need to boot from the DVD and run Disk Utility is that an active, mounted disk cannot be repaired.
If you want to save some time (bypassing the need for the DVD) on this and don't mind using single user mode (type a command similar to DOS on a PC) then do the following:
- Restart the Mac and hold down the Command (Apple) and 'S' keys simultaneously. This will put you into what is known as 'Single User Mode' (white text on a black background like DOS).
- At the prompt, type the command fsck -fy and press the 'Return' key.
- This will run through the same check/fix as Disk Utility.
- Repeat if errors are found (you can either retype or press the 'Arrow Up' key of the keyboard to revisit the command.
- If the error is resolved, type the command reboot and then press the 'Return' key. The Mac will reboot into its usual GUI interface.
Note 1: When in Disk Utility, look to the bottom part of the application window for the drive's 'S.M.A.R.T.' status. If it is 'Verified', your hardware is okay.
Note 2: I prefer to install a free app called AppleJack that gives you more functionality (disk check/repair, caches flush, preference checks etc..) in single user mode without needing to know the actual UNIX commands.
- If the error does not resolve (here or with Disk Utility from the DVD), your problem will require either a more powerful tool like DiskWarrior (commercial software) or backing up your present drive, reformatting it and re-installing.
