How can I erase My hard drive. Disk utility only gives me the option of erase free space. I have 27in iMac with Lion and 12 gb ram.

How can I erase my hard drive? Disk utility only gives me the option to erase free space.
Thanks for any assistance.

Drive Preparation for Lion
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, 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.
4. Quit DU to return to the main menu.
5. Select Reinstall Lion then click on the Continue button. You need an active network connection in order to download the Lion software.

  • How can I delete everything from my Time Capsule?  Disk Utility only gives me the choices of First Aid and Restore.

    How can I delete everything from my Time Capsule?  Disk Utility only gives me the choices of First Aid and Restore.

    How can I delete everything from my Time Capsule?
    Disk Utility would be used for an internal hard drive on your Mac, or for a drive that was attached directly using USB or FireWire.
    The Time Capsule is a network drive. Disk Utility cannot be used for this type of drive.
    Open Macintosh HD > Applications > Utiltiies > AirPort Utility
    Click Manual Setup
    Click the Disks icon
    Click the Disks tab below the icon
    Click Erase
    The "Quick Erase" option will only take a minute or so. This would be fine if you plan to keep the Time Capsule yourself.
    If you plan to sell the Time Capsule, you would want to use a more secure erase, like "Zero Out", which will likely take 4-6 hours or so since everything on the drive will be replaced with zeros.

  • How can I Replace a Hard Drive on a 160gb iPod Classic?

    How can I Replace a Hard Drive on a 160gb iPod Classic? I am considering buying an iPod Classic off of eBay which is described as 'broken' and having the 'Red X' showing up on the screen. The seller is starting the bid at a very low price, which raises some concerns for me. For this thread, let us assume that the iPod has a broken hard drive that needs to be replaced in order to function properly. I am assuming that merely 'restoring' it would not suffice. How would I be able to replace the hard drive myself, without bringing it in to a store? I have never fixed an iPod's hardware before, nor a computer or any electrical device. I am a novice at such things. Would I be able to fix it myself without wasting money on a broken iPod and new hard drive? Please provide instructions on how to do so =)

    Hello there,
    Yes, the red X icon is usually a sign of a bad or damaged hard drive. Sometimes, restoring the iPod will resolve the issue, but rarely. Other users were able to smack the ipod against the side of their leg and gain back full functionality of the iPod.
    However, if no such luck with either, your next option would be to replace the drive. For this task, you can either opt to repair and replace the hard drive yourself, or opt to send it into a third party repair business to do the job for you.
    I use the guides at [www.ifixit.com|http://www.ifixit.com> to help me replace broken parts on an iPod. These guides provide excellent step-by-step instructions as well as photos on how to repair any part from an iPod.
    Some other good sites for purchasing repair parts include the following:
    [iDemiGods|http://www.idemigods.com>
    [RapidRepair|http://www.rapidrepair.com>
    [iResq|http://www.iresq.com>
    Lastly, I would also like to remind you that ebay also has several great deals on excellent iPod replacement parts. It's where I purchase a majority of mine.
    Hope this helps.

  • Hard Drive Partition (I don't get the option to partition)

     I recently bought the Satellite Pro u400-142 and have installed XP pro from the recovery DVD. I am trying to partition my hard drive but am having difficulties in doing so. When in disk manager I right click the primary drive to bring up the partition wizard but the option is not there for me to create a partition (it has been greyed out).
    Does anybody know why this is and how can I partition my hard drive?

    No surprise there. My guess is that there is no unused space on that drive.
    In any case, you cannot use Disk Management (diskmgmt.msc) in Windows XP to repartition a drive containing Windows or its boot files. That is for other drives.
    Repartitioning is done outside of Windows, ordinarily with third-party software. I just repartitioned a laptop's disk containing Windows XP in order to add Windows 7. I used this free partition manager.

    For what purpose do you wish to repartition the drive?

  • I bought an iPad and an iTunes card, I want to buy an application from the Apps store but it only gives me the option of credit card.  How can I buy Pages with my iTunes card to my iPad? thank you

    I bought an iPad and an iTunes card, I want to buy an application from the Apps store but it only gives me the option of credit card.  How can I buy Pages with my iTunes card to my iPad? thank you

    Have you redeemed your iTunes card to an account associated with an Apple ID?
    Once you have your iPad associated with an Apple ID AND you have an account with a credit card associated with the same Apple ID AND you have some 'store credit' (from redeeming your iTunes card) then purchases use the store credit before they charge the credit card, so you should be ok!
    Personally, I use 'store credit' as a way to monitor whether or not there have been any 'unauthorised' purchases because as soon as the store credit is zero, the security code from the credit card is needed for further purchases!  It does mean that I have sometimes to top up store credit before making a purchase, but 'better safe than sorry'! 

  • I want to take the photos off my iPhone and put them directly onto an external hard disk. I want to bypass iPhoto altogether. When I link my iPhone to my computer, it only opens in iTunes, which only gives me the option to save my photos to iPhoto. Help!

    I want to take the photos off my iPhone and put them directly onto an external hard disk - I don't have any room left on my computer. I want to bypass iPhoto altogether. When I link my iPhone to my computer, it only opens in iTunes, which only gives me the option to save my photos to iPhoto. Help!  This is seriously frustrating!.
    Additionally, I'd like to be able to take the 2000+ photos out of iPhoto and put them on a disk in a folder. I have managed to export them to the hard disk but it's just plonked all 2000+ photos in a list - not ideal if I want to use it for anything else. And then I have to manually delete the photos from iPhoto. Is there not a quick and easy way of dealing with this? 
    Anyone got any bright ideas? Thanks for your help!

    I too would like to be able to do this. Just put them where i want the. IFTT a scripting app will put the images in dropbox for you , but its been pretty iffy.

    I have iPhoto 11 with Lion and when I try to post photos into MobileMe in Share I get the message that iPhoto is not connected to internet. Can anyone tell me how to connect iPhoto to internet?

    My solution, which is not much, is to restart iPhoto and it then connects to the Internet. This has been an ongoing unsolved problem.

  • When click the email icon on my iphone, it opens on one email only.  I can not go to the next or previous email, a different email or anything.  It only gives me the option to move that email!  How can I stop this.  Its been working perfectly well before!

    Now as you may know there is some icons at the bottom of the mail app, at the top left conner you should have the inbox button and on the upper right conner you should have two arrows to shift between emails. If any of those options works try :
    Settings>General>Reset>Reset all Settings
    If that does not work try to re add the account
    Last but not least, restore as new.
    Hope that helps.

  • I'm trying to sync a playlist onto my phone through the computer and it says my device is already synced with another computer with my iTunes account. It only lets me cancel or it gives me the option to erase my contents and sync. Help.

    I'm trying to sync a playlist onto my phone through the computer and it says my device is already synced with another computer with my iTunes account. It only lets me cancel or it gives me the option to erase my contents and sync. Wondering how to get my device from the other computer especially since I don't even know what computer it's connected to.

    At some stage is is likely to have been connected to another computer's iTunes.  It is now linked to that computer's library and iPhones can only be associated to one library at a time.  Linking to a different one requires wiping the phone.
    If you used the phone with another computer you owned you can transfer the iTunes library from that computer to this one and the phone will still be syncing with the same library it was before.
    If all there is on the phone are items which can be backed up to iTunes and purchases which can be transferred you could do that, then wipe the phone and sync them back.

  • How to uninstall bootcamp partition if the assistant only gives me the option to install bootcamp?

    I am trying to uninstall my Bootcamp partition but when I open bootcamp assistant it only gives me the option to install a bootcamp partition.
    Thanks

    Either use Paragon's CampTuneX to resize it or use Boot Camp Assistant to remove the partition and restore the drive to one partition. Then create a new, larger Boot Camp partition. This will remove/delete/erase your Windows system.
