Can someone point me in the right direction with this? I have the OS X Disk and the Applications Disk. I want to completely wipe everything off and start over.

    Clean Install of Snow Leopard

     

    Be sure to make a backup first because the following procedure will erase

    the drive and everything on it.

     

         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came

             with your computer.  Insert the disc into the optical drive and restart the computer.

             After the chime press and hold down the  "C" key.  Release the key when you see

             a small spinning gear appear below the dark gray Apple logo.

     

         2. After the installer loads select your language and click on the Continue

             button. When the menu bar appears select Disk Utility from the Utilities menu.

             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive

             size.)  Click on the Partition tab in the DU main window.  Set the number of

             partitions to one (1) from the Partitions drop down menu, click on Options button

             and select GUID, click on OK, then set the format type to MacOS Extended

             (Journaled, if supported), then click on the Apply button.

     

         3. When the formatting has completed quit DU and return to the installer.  Proceed

             with the OS X installation and follow the directions included with the installer.

     

         4. When the installation has completed your computer will Restart into the Setup

             Assistant. Be sure you configure your initial admin account with the exact same

             username and password that you used on your old drive. After you finish Setup

             Assistant will complete the installation after which you will be running a fresh

             install of OS X.  You can now begin the update process by opening Software

             Update and installing all recommended updates to bring your installation current.

     

    Download and install Mac OS X 10.6.8 Update Combo v1.1.

    With Snow Leopard you will need to restart the iMac with the DVD in the disk drive and hold the C key down.  Then from Utilities select either erase and install or use Disk Utilities to erase the hard drive and then install SL.

     

    But first, is there a specific reason for doing this?  Often problems can be fixed without such drastic actions.

    OK, I'll try explaining this as simply as I can. The best way is to have you look at my other post about video files that keep repopulating my Move list when I try to convert the videos. A computer guy yesterday told me he thinks it's the old trashed thumbnails that keep coming back instead of the full 1.5 GB video. Go here and read this and that will explain why I want to gut my Mac. https://discussions.apple.com/message/23873034#23873034

    In case you didn't read my post, I never asked why. I don't really care why. You asked how, and I posted how. It's the other poster who asked you why.

    Sorry, I clicked on the wrong post. I read your post and already went through all that stuff and ended up at a dead end because Disk Utilty won't let me erase, the Format and Name areas are greyed out and I'm locked out some how.

    OK, I'll try explaining this as simply as I can.  I accidently trashed a bunch of my Video files I had converted from MP4 to VOB, and when I try converting the MP4s again to replace the VOB files, it repolulates from the emptied trash with a tiny low quality 1 MB file instead of the full 1.5 GB video. I have been beating my brains out trying to figure out how to get my original 1.5 - 2 GB VOB files back.

    Did you create a new partition?

     

             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive

             size.)  Click on the Partition tab in the DU main window.  Set the number of

             partitions to one (1) from the Partitions drop down menu, click on Options button

             and select GUID, click on OK, then set the format type to MacOS Extended

             (Journaled, if supported), then click on the Apply button.

    Hmmm, no I didn't do that because I didn't see it in the guide on my disk. I don't remember doing that when I re-formatted my Xternal hard drives either, just renamed them. I'll give this a try........ unless Ralph has an idea how to re-convert my MP4 files at full size. I would much rather do that if possible.

    Sorry, but idon't have a ready solution to recreating video files...back converting from one format to another always makes a mess of things for me...the file is never equal to the original...the different compression formats strip out too much information that cannot be added back.

     

    At least with photos I use a dedicated drive for all original files, pull what I want to work on into the iPhoto library so the original stays intact.  It is always a good idea to keep important files of any type in a safe, dedicated location.

    To be honest, I really don't even know how to specify a safe location to store my original files, unless you're talking about an external drive. I have 2 2TB externals if thaat's what you mean. I have been storing my music, photo and Video files on one of them, but the problem here is I had not put them on there yet.

    That's what I am talking about, a separate drive for important, original files...and I hate to admit how many times I too have said I'll put the file there later only to do something that damages the file in the interim...what we call being human :-)
