Were you able to boot into the Recovery Partition? Do a backup, preferably 2.
You can make a bootable USB stick to install using this free program.

How to restore my iPhone when my backup doesn't show up?

Today 12/28/13, I brought my iPhone 5 into an apple store to get a battery replacement and had to delete everything on my iphone. I backed up my iphone a few nights before and made sure that everything was saved onto my computer. When I came home after the battery replacement, I went to restore my phone from the previous backup 12/24/13, but instead, iTunes backed up my 12/28/13 phone with all of the erased content and wouldn't show the back up I actually wanted, the 12/24/13. I tried going into device preferences and that didn't show the backup I wanted either. When I searched through the backup folder in my computers system (windows 7), I went into Mobilesync, backup, and found the backup folder I actually want back onto my itunes and dragged it onto my desktop.
Now my question is, how do I move this folder back onto my itunes? This is the only backup I want back.

To move the folder back you need to access:
\Users\(your username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
And insert the folder back to it, iTunes will automatically recognise it

How can I repair disk permissions

How can I repair disk permissions on a non boot drive? I have a SSD as my boot disk and a HD as a storage drive. The permissions are not correct on th HD and in disk util the option for fixing the permissions is ghosted out. I really would hate to do this one folder at a time.
Thanks

FYI, BB
Below is a quote from Apple describing what Disk Permissions deals with.
If you still need assistance, please describe what problem/issue you are trying to solve.
http://support.apple.com/kb/HT1452
"Many things you install in Mac OS X are installed from package files (whose filename extension is ".pkg"). Each time something is installed from a package file, a "Bill of Materials" file (whose filename extension is ".bom") is stored in the package's receipt file, which is kept in /Library/Receipts/ in Mac OS X v10.5 and earlier. These files don't take up much disk space and you shouldn't put them in the Trash. Each of those ".bom" files contains a list of the files installed by that package, and the proper permissions for each file.
Does Disk Utility check permissions on all files?
Files that aren't installed as part of an Apple-originated installer package are not listed in a receipt and therefore are not checked. For example, if you install an application using a non-Apple installer application, or by copying it from a disk image, network volume, or other disk instead of installing it via Installer, a receipt file isn't created."
Is this what you want to "fix"?

Automatic Error when opening Disk Utility

Hi guys, I recently noticed this problem when clicking "Calculate Image Checksum..." in the finder pulldown menu for Disk Utility. I don't open Disk Utility often, so I can't be sure if this error has always existed or if it only has recently began occurring. Anyways, when I open up Disk Utility, it seems as though it is detecting a .dmg file on my desktop named "Desktop.dmg." When opening Disk Utility and calculating image checksum, I automatically get a pop up error saying:
Disk Utility Progress:
Unable to checksum "Desktop". (Operation not supported on socket)
When opening Disk Utility regularly, (by going to Applications -> Utilities -> Disk Utility) the Desktop.dmg file is not there. Is this normal? Is there any way I can prevent the Desktop.dmg from showing up?
Any help appreciated,
Thank you!

ive also noticed that if i have the "Macintosh HD" icon highlighted on the desktop, then attempt to calculate checksum, then when Disk Utility opens up it proceeds to checksum the drive and prompts for my password.
So it seems as though whatever it is that is highlighted in finder, Disk Utility will somehow create a .dmg file with the same name and try to mount it. Since this is not a real disk image, the error pops up. I am very puzzled by this, can anybody give me some insight?

How long does Repair Disk take?

When starting up my iMac - only bought 3 weeks ago, I open Safari and my screen gets a black screen over it and say "You need to restart your computer. Hold down..." after 3 times of doing this I rung apple and went through some steps with technical help. I'm now waiting for Disk Utility to repair my disk - it's been over an hour. How long should this take?

An hour seems too long to me. That screen effect and message sound like a kernel panic. Such freezes are generally attributed to hardware but not always.
If the machine is only three weeks old and you are getting kernel panics, I'd make a booking for the shop to check it out.

Macbook shuts off during start-up - can't get through safe-mode, single user mode (fsck -fy) and target-drive shows no problems when running disk utility repair

Hi everyone,
I'm simply all out of ideas on what to do - my best guess is the problem is not specifically hard-drive related since all the 'normal' fixes just won't work.
What could be the cause of my issue? The only way i've managed to keep the Macbook Pro on for longer than a minute is through target drive, where it seems to work just fine - i can access everything. To sum up everything:
1 - I tried resetting the PRAM
2 - I tried to go in to safe mode, it shut off before i could type the password
3 - I tried fsck -fy command from single user mode, sometimes i can get to actually typing it but mostly it shuts off before
4 - I tried to repair disk via target drive - success, no problems detected (and it didnt fix my issue)
5 - I reinstalled OS Mavericks.
The Macbook Pro previously had some problems with the power-button not working properly (a mac-cunning friend of mine had to open up the mac and start it by swiping to metal pins on a specific (battery/power?) part inside it. The problem kinda went away afterwards but it might be related to this?
This is way off my comfort zone of 'diagnosing' issues, so I'm crossing fingers for some good advice.
Thanks,
Aske

I think you're right.
If it's hardware related, is it possible to guess at what it might be? It would be nice to know how much I should expect to pay for a repair before actually getting it fixed.

I recently downloaded is x mountain lion and while it finished it erased all my data, some of which I need. When using disk utility I found my old data but it says corrupted. I can't repair and while restoring the error code 32 Broken Pipe appears. Help?

My data I need is on my computer but it needs to be repaired but can't and when I try to restore it/back it up it ends abruptly with error code 32 broken pipe.
It was damaged while installing os x mountain lion and I found my data on disk repair (utility)

Sounds like your hard drive is badly corrupted, likely due to problems that were already there when you started trying to install Mountain Lion. The problem is, if you don't have any backups already, you may not be able to recover all your data from this state. Do you have backups of that data already?
If not, I assume when you say that "it needs to be repaired but can't," you mean that Disk Utility tells you there is a problem with the disk, but that it is unable to repair it? If so, you can try repairing the drive using DiskWarrior, which can repair problems that Disk Utility cannot. That may give you access to your data again, but may not.
Also, it's important to understand that if your data is not backed up, everything you do with the computer runs the risk of overwriting or corrupting that data. You may want to go straight to trying to recover your data. See Recovering deleted files.
Regarding the error code, if you're trying to back up the drive using Disk Utility's Restore tab, note that that is often not successful when the drive you're trying to back up is corrupt.
Once the situation is resolved - either because you have backups, are able to recover your data files or are forced to accept that they are gone permanently - you will need to erase the hard drive and reinstall the system and all your apps from scratch.

How can i repair disk permissions i know i altered?

sigh... this is the second time i've fudged my wife's MacBook.
i downloaded some music on my MBP. i then gave her the same files via USB (then again later via Bonjour). the files work on my MBP and on my iPod Touch no problem. her MacBook received the files into her inbox no problem. but in iTunes, trying to add the files into her Library, an error comes up saying roughly 'you do not have sufficient access to preform this action'. a few google searches later, i figured it was a permissions problem in the file folders.
command-I over her Music Folder, change privileges to "Read and Write" for 'My Wife', 'Admin', and 'Everyone'. click the gears icon below that, and 'Apply to Enclosed Items'. restart.
didn't work. so i thought to myself: hmmm, maybe its a folder im not thinking to check. if i just changed those permissions across the board, it'll work then! i'm so smart.
command-I over her disc icon on the desktop, change privileges to "read and Write" for 'My Wife', 'Admin', and 'Everyone'. click the gears icon below that, and 'Apply to Enclosed Items'. restart.
Grey Screen... Apple Logo... Wheel... automatic restart... Grey Screen... Apple Logo... Wheel... automatic restart... over, and over, and over.
ok, so i troubleshoot on the forums here. after quite a few reads, i land on:
http://support.apple.com/kb/HT1379
follow steps for safe boot, no luck.
follow steps for resetting PRAM, nuthin.
follow steps for Disk Utility, and i find there were quite a few Permissions that were changed (duh).
the Repair Permissions finishes and most of the log says the 'Permissions were modified and will not be Repaired'. i know i can ignore most of the SUID files that won't be repaired, but there a re a handful of files that im sure are causing the problem. is there another step i can take here? can i rewrite the permissions for the problem files in the terminal?
or am i barking up the wrong tree here entirely?
Archive and install is my next step, but i want that to be my last resort, if only because she's gonna kill me. the last time i "fixed" her MacBook, it ran me $280 for the file recovery service. we're in a recession people, i don't wanna blow another $280.

that was not clever. you now have to do an archive and install. and in the future NEVER EVER and I mean under ANY conditions use "apply to enclosed items" on ANY system created folders and your startup drive. that includes among other things your home directory, your Music folder, your desktop folder, etc. Use it ONLY on folders you make yourself. you should never change permissions on system files period. the reason you shouldn't do it on system created folders in your home directory like the Music folder is that such folders often have hidden ACLs and using "apply to enclosed items" will propagate those ACLs to everything inside. in particular, the Music folder has "everyone deny delete" ACLs and if you use "apply to enclosed items" on it you'll have to enter your admin password any time you need to delete move or rename anything in that folder.
restart.

How can I "repair disk" with Repair disk grayed out?

My external back-up has been complaining of late, Time Machine can no longer access it, and now, after trying Verify Disk, it stopped that process and told me to use Repair Disk.
Repair Disk is grayed out. But my WD unit isn't even six months old.
Where do I turn?

I found a Grab of part of the response from Verify Disk.
If that's impossible to read, (1) blame Apple and (2) let me know -- I'll punch it up.

How do I fix a volume if Disk utility says cannot be repaired?

Greetings all,
Am having some annoying issues with my PowerMac G5 hard drive, nothing very specific, just lots of small issues like crashes and hangs and the fan going into hyper-drive every now and then. Started up from my system disc/Disk Utility and ran repair permissions and repair disc.
On repair disk it gets to the end then says:
1 HFS volume repaired
1 volume could not be repaired
I cannot find out what this means so can anyone advise?
I also run repair permissions over and over and it never stops finding something to repair.
Any advice much appreciated.

Started up from my system disc/Disk Utility and ran repair permissions and repair disc.
Do you mean the System install DVD? - that's what you should do as you cannot repair an HD you're booted from.
On repair disk it gets to the end then says:
1 HFS volume repaired
1 volume could not be repaired
This is a little odd: is there another hard disk connected? Or possibly it was trying to repair the install disk as well?
I also run repair permissions over and over and it never stops finding something to repair.
Repairing permissions does thrown up a lot of things which can't be repaired: this is a bug arising from a system update and is harmless: you can ignore it.
You could try downloading Applejack which you run in single-user mode and provides an easy way of using the built-in disk repair procedure: this is quicker than starting from the DVD and you won't get any confusion with the DVD. It's quite safe: it doesn't do the check itself, just invokes the repair that you would get by typing arcane Linux codes. But note that you must run it only in single user mode (starting up and holding command-s while booting), never while booted normally.

Permissions repair/ disk utility

Hello:
I believe I have a permissions repair problem as but I'm not entirely sure.
I'm very untechnical and somewhat shakey on my conclusions and how to
proceed.
My computer slowed down this week after downloading freeware. I dumped all but one program. My space bar doesn't work properly as of last night, It only moves on the sides when hit hard. Most words just run together as I type.
Then today, I suddenly can't open Word documents. I forced quit and then restarted and then couldn't open PDF files either after working on the computer all day. Forced quit on Preview then couldn't open the hard drive as well. I was able to get into it through the applications icon.
Apple help suggests it's a permissions repair problem, but I'm confused. Went to disk utility and it says to install the OS X cd. I only have the PowerBook G4 Software Install and Repair disks. Are these one and the same?
I'd really appreciate any guidance on figuring this out and then how to proceed.
Thanks so much.

Hi Don:
Thanks for your help a couple of weeks ago. Just now attempting to solve.
Have used Mac Janitor and Cache Out X tonight and the inability to open files
on the desk top remains, as well not being able to open bookmarks in Safari in addition to having the same problem using the spacebar.
Wanted to ask some questions about your recommendations:
1) When using Cache Out X, do I want to delete Caches from the User Domain
as well as the Internet?
2) Do I launch all of the icons in Onyx? The help menu was very confusing.
3) I was unable to find Gullivers Link. Can you please explain this as well?
Additionally, while this note is correctly laid out while typing it, the preview page reveals line breaks that are not evident to me. This happens all the time
in emails. Any ideas?
Many thanks--
Beth

Repairing Disk Utility more

Ok so I had this question earlier today:
"Ok, last night there was an update for OSx Lion. I installed the 3 items, it said I needed to restart, which I did. When it restarted there was another box, which was checking the updates or something. After that finished, it logged into my home screen, and I shut it off. Today, I tried turning it on and it was stuck. After 10 minutes, I held the power button to shut it off and try again. I did this twice, and on the third time a loading bar showed up at the bottom of the screen, went for a while and almost reached halfway, then it dissappeared. I waited, but nothing happened. What's wrong and how to I fix it?"
I was told to fix the start-up disk with Disk Utility by using command-R. When I tried that, It gave me the options of a 500.11 GB thing, the Macintosh HD, SuperDrive, disk1, and Mac OS X Base System. I tried repairing all the them, and they were all fine except the "Macintosh HD" Heres what the report said exactly:
Checking the system
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Invalid index key (in red)
Rebuilding catalog B-tree.
The volume Hacintosh HD could not be repaired. (red)
Volume repair complete.
Updating boot suppport partitions for the volume as required.
Error: Disk Utility can't repair this disk...disk, and restore your backed-up files.
Also, this box came up:
Disk Utitly stopped repairing "Macintosh HD"
Disk Utitity can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
My question is, what do I do next to get my computer up and running, in simple terms.

...didn't back up anything with time machine, which is what I think is what you mean...
No, I did not mean Time Machine. (FWIW, Time Machine backups should be made to an external drive, not to another volume on the same drive as the primary boot volume. Reason - if you lose the drive, you lose everything inluding the backup.)
The files you need to copy off are the ones you spent time creating - financial files, word processing files, whatever you've spent time making. Software, programs etc., can be replaced simply by re-installing them. But the manhours you've invested in creating documents can never be recaptured if the files themselves are lost.
So, where are they? Unfortunately, the answer is wherever you placed them.
Everyone's work habits are different. For example, I do not use the Documents folder for anything. I make project (like "ABC Club" or "IRS") folders and kind (like "pictures" or "thoughts") folders, place them where they're convenient, and put the files I make or get in those folders as appropriate. The arrangement of those folders, which are in what and where, follow my own personal logic - after all, the purpose of a filing system is not to have a place to put things, it is to have a place to find things.
So, where they are is where you put them.

AirPort disk 'needs repair', Disk Utility finds nothing wrong...

I have a 640GB hard disk that was just formatted for use as an AirPort disk. I zeroed the disk on my PC and then formatted it in Disk Utility while it was attached to my USB hard disk dock. Because the original partition scheme I tried to do would not format as specified (i.e., Disk Utility decided that since I put free space as the first partition with four partitions, that what I really wanted was just the three partitions), I repartitioned the disk as follows: 64.00GB for HFS+, 32.00GB for FAT32, 512.00GB for HFS+, 32.00GB for FAT32 (using Master Boot Record). After this completed, I ran Windows XP on my PC and diskmgmt.msc with the intention of deleting the first partition 64.00GB HFS+ and replacing that with 64.00GB NTFS. This seemed to work fine on Windows XP, but I could not do it on Windows 7 because Windows 7 automatically makes the last partition on MBR an Extended Partition without asking if you want it to be a Primary/Extended Partition. Next, as I only intended to boot this on my old PC, which I rarely use, I installed Windows XP on to the first partition (now 64.00GB for NTFS). The installation went fine, as well as the software I installed in Windows that will allow me to see the HFS+ partition from a Windows boot. This software recognized the partition and mounted it in Windows. Next, I shut down the PC and put the disk back into the USB dock to see if all was well from the Mac side. Disk Utility did not report any issue with the disk and was able to see and mount all of the partitions correctly; however, when I attached this disk to my AirPort Extreme, the light started blinking amber and, upon further inspection, was told that the "AirPort disk needs to be repaired". I went back to Disk Utility and verified the disk without issue, but no problems were found. To be complete, I also repaired the disk in Disk Utility, but still it seemed to find nothing wrong and the repair had no effect on the AirPort error message. When I attach the disk to my AirPort Extreme, it will only mount the two partitions that are FAT32. The HFS+ partition does not show at all. I understand that the NTFS partition will not show over AirPort, which is why I chose a small size for it. My main reason for creating the NTFS partition is so that if I ever have a problem with my AirPort Extreme or need to work with a large file, I will have faster access if it is on a SATA connection inside my older PC than over WiFi or connected to my USB hard disk dock. Windows XP does not recognize the default OS X partition type, so that was not an option. Any assistance on how to address this issue would be greatly appreciated. The applicable operating systems are: Snow Leopard (my Mac mini), Windows XP Pro SP3 (on the old PC) and Windows 7 (on the newer PC that is attached to the AirPort Extreme).
