    I am getting ready to sell my macbook pro. I have never sold a mac in the past. On windows I knew how to zero out the hard drive before sale. I want to make sure the new owner can't retrive info from the laptop before I sell it. What is the best way to do this?

    Thanks

    Disk Utility can do this under the Security Options.

    Wouldn't disk utility erase the mac OS as well. In windows I go into dos and use a utility from there to zero out the hard drive.

    Confused.

    Here is what I do.

    On a Windows computer:
    - Boot from floppy or CD with KillDisk. Run it a few times (free version only does one pass).
    - Do a clean install of Windows (from the install CD).

    On a Mac computer:
    - Boot from the install DVD. Run Disk Utility and securely erase the HD with 7 passes.
    - Do a clean install of the Mac OS (from the install disks).

    I agree with Sushi in all particulars for the Mac. On a PC I use a linux disc to zero things out.

    Anyhow, the Disk Utility thing is really easy. I used it like that when I added a new internal hard drive.

    If you darn please, you can always just fill your HDD with porn and then reinstall the OS :)
