My hard disk of mac has failed. How do i recover my data

Buy a good USB enclosure for your old drive.
Then try something such as Data Rescue 3 (which I have successfully used and can recommend) or DiskWarrior to TRY to grab some of your data off the drive. How much data will depend on how damaged the drive actually is.
Good luck,
Clinton

My hard disc has failed how can I download data from my ipod to a new hard disc?

my hard disc has failed how do i transfer the data on my Ipod/Ipad to a new hard disc?

In addition to the comments above, when you create a new library with the media that you recover this will be treated as "new" for the device and iTunes may want to wipe it and start over, losing any personal data and settings. The following approach ought to help.
You should be able to:
Backup the device to your iTunes installation
Transfer your purchases into a library authorized to your account
Recover any other media using third party tools as suggested in this post from forum regular Zevoneer (same as above)
Restore the device from the backup
This process should switch the association of the device to the new library, preserving the data and settings in your apps.
May also be prudent to attempt a backup to iCloud directly from the device before you start... Settings > iCloud > Storage & Backup > iCloud Backup > On. It won't save any media but it would preserve the general account settings and documents in case anything goes wrong while you are trying to extract your other data.
When you get it all fixed, make a backup!

HT201272 Having a bad day my iTunes library got corrupted and my back up disk has failed how can I restore my purchases from the iTunes store

Having a bad day my iTunes library got corrupted and my back up disk has failed how can I restore my purchases from the iTunes store? When I try it tells me the pruchases have already been downloaded to this computer.

Does your purchased rmusic appears under the Purchased link under Quicklinks on the right-hand side of the iTunes store home page (music can't be re-downloaded in all countries) ? If they do and you don't have the cloud symbol against them so as to re-download them, then do you still have the entries for them in your library i.e. where you would normally click on them to play them ? If you do then try deleting them from there (iTunes will be seeing them and assuming that you still have them somewhere) and they should then get the cloud symbol for re-downloading in the Purchased link.
If you aren't in a country where music can be re-downloaded then you could try contacting iTunes support and see if they will grant you a re-download : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page,

How can i transfer all my data 250 GB from external hard disk to MAC pro

How can i transfer all my data 250 GB from external hard disk to MAC pro

The simple answer is just connect the external hard drive and drag the files from there to wherever you want them to go. If you need to do something more specific, you'll have to provide more details.

Hard disk in mums macbook failed, bought a new one, formatted it first. Have tried starting it with every possible key and I either get flashing question mark folder or a cursor.

Hard disk in mums macbook failed, bought a new one, used sata adapter cable to format it for mac first. Connected it and have tried starting it with every possible key combination and I either get flashing question mark folder or a cursor. A disk is stuck in it so I can't boot from OSX, and yes I have tried every option of starting to try and eject disk but none work. HELP ME!

Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the
      left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in
      your Utilities folder. At the prompt enter or paste the following:
        /usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
If you have a 2010 MBP or later, then you can use Internet Recovery. Start by rebooting the computer. At the chime press and hold down the COMMAND-OPTION-R keys until a Globe appears in the upper part of the screen. This process can take upwards of 15 minutes to get connected to the Apple network servers. You should eventually see the utility screen of the Recovery HD. You may now go about the process to install Mountain Lion:
Install Lion/Mountain Lion on a New HDD/SDD
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

HT4859 I have unwillingly synced my iPhone to my wife's iPhone. All her information got tranfered to my phone and over-rode all my contacts and data. How do I recover MY date that was backed up on iCloud yesterday?

This morning I ave unknowingly synced my iPhone to my wife's iPhone's data in iTunes. Now all HER information is on my is on my phone and all of my information has been overwritten. How do I recover my data and overwrite her data. My latest backup to iCloud was yesterday. I have not backed up my phone today and have turned off the auto back up feature, hoping I can still retreive yesterday's data. Can anyone help?

Welcome to the Apple community.
You will need to restore your phone and when prompted use the backup that you made yesterday.
Before you do so, you may wish to change your wife's iCloud login details, otherwise you may find that you then overwrite her data. She should have her own iCloud account to avoid this.

You should never update without making sure that you have saved everything on your computer first.
You should import all pics and vids before attempting any update.
If you have failed to save the data, then it is gone

HELP! old M505 has crashed and need to recover the data on it

Hey all,
I'm hoping someone out there has some creative idea on how I can recover the data that was lost on my old M505. I went on a long vacation and when I returned it had completely run out of power. Unfortunately after recharging it, the system started at the initial installation screens and had lost all of my addresses, which I had not backed up in a very long time.
If anyone has any great ideas, it would be very much appreciated.
Sincerely,
Bob Last
Post relates to: Palm m505

Hi, and welcome to the Palm Support Community.
Sorry, but there is no good news here.
Your old m505 has what is called "volatile" memory, which means that it requires power to maintain it. Once the batteries die, there is a small capacitor which holds just enough power to preserve data for another few days. After that, it's << poof ! >> gone and there is no way to retrieve it if you don't have it backed up to your computer.

How do I recover Apps Data from the iCloud on iPhone 4S with IOS 6.1?

How do I recover Apps Data from the iCloud on iPhone 4S with IOS 6.1?

You would have to restore to your entire iCloud backup, if you have one. (The backup includes app data.) Restoring to an iCloud backup has to be done in the initial setup process. If you have any data on your phone now that is not in the backup that you want to save you'll need to do that first. Then go to Settings>General>Reset and tap Erase All Content and Settings. You will then go through the setup screens as you did when the phone was new. When given the option, choose Restore from iCloud Backup. Be sure you are connected to wifi and your charger as this will take some time to finish.

If all your files are missing
You may have logged in as a different user, such as Guest. Open the Users & Groups pane in System Preferences. Your name should be at the top of the user list, under Current User. See also this support article.
If files are missing from one folder
Change the Finder view mode; for example, from icon view to list view, or vice versa.
