Why does my disk keep ejecting

when i insert my disk into the computer it reads it then automaticl ejects the disk.  How do i make the computer ready the disk.  I have an imac early 2008 with intel core i2 adn 4 gb of ram

If it is just that one disk, then it may be dirty or scratched. Use a clean damp cloth to gently wipe off fingerprints and dirt in a radial (center to edge) motion, not in a circular motion.
If this happens with all disks, your optical drive may be broken. You would then either need to replace it or obtain an external optical drive.

  • Why does my computer keep ejecting the snow leopard install disk

    I am trying to upgrade from leopard to snow leopard on my MacBook Pro. However, every time I insert the install disk, the machine whirs for a moment, and then ejects the disk with no error message. I tested my drive with a different dvd and it works just fine. All of my other software is up to date. Any idea what could be causing this or what I can do?

    Clean the bottom of the disk with a bit of rubbing alcohol and a soft cloth, polish to a shine.
    If it's a PowerPC Mac it won't upgrade.
    Must be a 10.6.3 Snow Leopard retail disk (white with cat like my avatar)
    Try holding the c key down with the disk inserted and then reboot.
    If all that fails, the disk is likely bad. It happens.
    You can chose to copy it and hope the errors get fixed or exchange it for another with Apple.
    Insert your Snow Leopard DVD.
    Open /Applications/Utilities/Disk Utility.app.
    In the left side of the window, select the “Mac OS X Install DVD”.
    Click “New Image” from the Disk Utility toolbar and select where you want to save the temporary image. For “Image Format”, choose “DVD/CD master” and for “Encryption”, choose “none”.
    The image extension in the “Save As” box will be .cdr (this is what you want) — click “Save”.
    Once the temporary image is created, it will show up on the left side of the Disk Utility window. Select it.
    Insert a blank dual-layer DVD
    Click “Burn” from the Disk Utility toolbar.

  • Why does my mac keep ejecting my WB external even after I repaired it in the disk utility?

    it also does this with my itouch and I have to keep reinstlling itunes just to synch my music.

    By WB do you mean Western Digitial? If so there may be a problem with the HD, WD EHD's don't have a good track record with OS X. They are popular because they're cheap however the enclosures they use eventually cause problems with OS X.

  • Why does my ipod keep on deleting my photos

    why does my ipod keep on deleting my phots after i download it to the computer?

    Periodically double click the home button and close all the apps in the recently used dock. Then power off and then back on the iPod. This frees up memory. The 4G only has 256 MB of memory.
    - Reset the iOS device. Nothing will be lost       
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Unsync/delete all music and resync
    - Restore from backup. See:                                                
    iOS: How to back up                                                                                     
    - Restore to factory settings/new iOS device.             
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

  • Why does my mouse keep losing connection every minute

    why does my mouse keep losing connection every minute, its not the batteries

    I'm having the same issue.  Every so often it loses connection then re establishes. This goes on repeatedly.
    If you change batteries while the computer is still active then it takes for ever to re connect.
    Can't wait until someone replies to your question.

  • HT5868 why does my iphone KEEP asking if I trust this computer? I thought it was a onetime thing per computer?

    Why does my iPhone KEEP asking if I trust this computer? I thought it was a onetime thing per computer? I plug my iPhone 4s into the computer and every time I tell it to trust this computer, but a hour later if I plug in again, I have to say trust again... bug? Setting issue? Help?

    http://helpios7.com/trust-this-computer-pop-up-fix/
    This helped me. Fix #1 is something Apple doesn't ever suggest to you.
    My specific problem was somehow my Apple Mobile Device USB Driver got turned off and moved and maybe even uninstalled, but after hours of struggling, this site helped tremendously.
    Furthermore, I could connect my iPhone to my computer but not into iTunes. It would only let me go to access pictures on my iPhone and that's all.
    Best of luck to anyone trying to figure out their problem.

  • Why does my iphone4 keep losing some of my newly entered contacts?

    Why does my iphone4 keep losing some of my newly entered contacts?

    When an app is downloaded to your phone what is downloading is an installer. Once the installer downloads in installs the app and then is deleted. You can see a reference to this if you watch the App's icon in the App Store after you tap on download. It will first say downloading then that will change to installing. The amount of free space on your phone must be enough to accommodate the installer and the app plus have some left over for system work. You're just too close to the minimum for everything to work.

  • Why does my trackpad keep losing connection

    why does my trackpad keep losing connection

    I am using Mountain Lion on a 2011 Macbook Pro and this is happening to me.
    The notebook never used to drop the connection on Snow Leopard or Lion as far as I can remember.  At first it was fine on Mountain Lion as well I think, but after the last couple updates the connection to the trackpad is gone when it wakes from sleep.  Dropping down to Bluetooth and choosing connect does not help.  It must be deleted and repaired each time under sytem preferences and bluetooth settings.  Batteries are fine, Apple rechargables, lights up green when tap button.  I also have an Apple keyboard used for this notebook and that never loses connection.  Just the trackpad, and only after the most recent updates the past month or so.  It pairs fine at first, then the connection is gone and I can't get it back without very inconvenient deleting and repairing.
    I seem to remember it happening shortly after a long update.  I am currently on 10.8.2.
