HT1782 How to reformat the disk and restore from backup
DISk utility found errors that could not be repaired. The instruction said to back up all files and then restore with backup. How do I do this? Will the restore also restore the errors?
Backup all you data using Time Machine or a clone program. Boot into the Recovery Mode (command - R during a restart), erase the disk and reformat it as Mac OS Extended (Journaled). From the Options button, choose GUID. The restore may or may not restore the errors, depending on what caused the errors.

Disk Repair reported that it could not repair the HD Disk. I am to reformat the disk and restore backed up files. OSX Utilities give me a choice of restoring from time machine backup (which I have on MyPassport) but no information on reformatting the disk, which I assume I have to do first. How do I reformat the HD ...or does the restore from Time Machine do both things?
Boot OS X Recovery and use Disk Utility.
If Disk Utility reported the disk cannot be repaired though, you should replace it with a new one. -
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

Can I fix a disk with this message?
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.Some problems can indeed be fixed this way. But working from Recovery_HD or Disk Warrior DVDs and working in the restricted environment those provide can be difficult. You can literally spend days working on this problem (while your regular work is unavailable) only to discover the old drive is unsalvageable.
There is no way to know up front whether you are facing a major Hardware failure or a minor software glitch, or something in between. Often you are forced to work from the drive you no longer trust. I continue to recommend you do this work from a different, fully functioning Mac OS X booted from a different drive.
If you have had the foresight to (as The hatter often recommends) clone your virgin install onto another drive for use in such situations, you will be able to recover from such problems in record time. If not, my previous recommendations stands:
Buy a new Drive. Or two. Install Mac OS X from scratch on a new drive, and get your Mac running again. Later, you can use the full power of Mac OS X to attempt to rescue your data, if needed. Then Zero the old drive, to see if it can hold data again reliably.
If the old drive eventually provides some needed data, and is salvageable, Merry Christmas. -
I am frustrated having paid for "Clean My Mac" which I run regularly and using tips like cleaning the cache in Terminal view. It is still getting slower. Can I clean off the disk and reinstall from my Time Machine, or will it re load the problem too? How do I do this anyway?

Get an external drive of sufficient capacity to hold everything on your internal drive.
Partition and format the external drive.

Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.

Hi, my Western Digital HDD crashed few days ago.
I had approximatly 450GB on it.
It doesn't want to be repaired or verified.
Does someone know a way to save all my files before restoring the Western Digital drive ?
Thanks you by advance.
Hope you will find a way.
NicoNico,
Did you find a way?
This just happened to me too.

Disk Utility stopped repairing the disk. I was instructed to backup as many of my files as possible.reformat the disk and restore my backed up files. Since I use time machine, can I assume that all my files and programs can be restored from my recent back ups?
Hi jeromefrodia,
Welcome to the Apple Support Community!
I understand that you are concerned about your data before reformatting the disk. Because you use Time Machine your information should be safe. Please refer to the attached article for information about what Time Machine backs up and how to restore from that backup.

You can't have received an error message "Disk Utility can't repair this disk...disk, and restore your backuped-up file." since that is pure gobbledegook and isn't even good English.
What may have happened is that
(a) your hard drive has become so full that the operating system can't find any space in which to.... operate.
(b) as macjack says, it has crashed - possibly as a result of (a).
(c) you have been allowing Time Machine to back up to your internal hard drive instead of to a backup disk, which has caused (a) to happen. -
My 3gs wont restore after ios 5 update. I have tried firmware restore and restore from backup, neither works. All I get is "iphone restore failed because backup session failed" Any ideas on how to make a successful restore with this ios 5 update?
I was having the same problem, I backed up my phone and then updated to iOS 5 and then it kept telling me it could not restore from my backup as it had failed. After reading a bunch of forums and posts and trying everything, I did manage to get it to work. I had tried the Time zone, creating a new computer user account, disabling anti-virus, etc.
It took a combination of things, one of which was disabling the anti-virus completely and copying the contents of the backup folder to my desktop and then deleting everything in the backup folder. Then I rebooted the PC, entirely disabled the anti-virus, copied the one backup I wanted to restore from the desktop to the backup folder and then trying to restore. Low and behold the phone said restoring from backup and I am back in business, so when in doubt, trying combining some of the fixes together. -
While updating my iphone 4s to ios6, I had to restore it. Now every time I connect to itunes, I get the "Set Up Your iPhone" window with the set up as new iphone and restore from backup options. After the restore, I got everything except my apps and music back. Do I need to set the phone up as new again?
