    Hi. What is the best way to completely erase everything on the computer so that images are not in the RAM or temporary memory anymore? I was looking at bikini models and I was redirected to another porn site. It popped up a bunch of other sites too. I would just like to start new with this computer by reinstalling the operating system so that everything is completely erased. I read something about reinstalling Mac OS X multiple times to completely erase everything.

    I have a MacBook Pro. Thank you.

    Back up data
    Reboot from CD
    Use erase and install method
    I don't know why you would reinstall more than once and I don't see any reason to write zeros to the hard drive.

    What does it mean to write zeroes to the hard drive? Does the method you mentioned delete everything and make it unrecoverable?

    Thanks.

    Porn isn't illegal. Who cares? Writing zeros takes awhile.

    You want to reinstall your OS and format your hard drive because you have seen 'bikini models' and porn sites? Are you paranoid?

    Your going very overboard. Having porn displayed on your machine doesn't mean it loses its innocence or anything. It'll just be in your browser cache for a little while and will eventually be overwritten. Doing any kind of reinstall is a total waste of your time. If you're worried about your parents finding out you saw porn just delete browser history and you'll be fine.

    I see you already have another thread going on about zapping the RAM.

    Writing zeros and ones to disk, means that hdd space that was formerly allocated by data, and now trashed, will be written over with 1s and 0s, to make that data harder to recover.

    If you fear for recovering those bad porn site by someone else, a simple deleting of the trash and the browsers cache (Users/You/Library/Safari or Users/You/Library/Application Support/"Name of the browser") and then emptying the Trash securely (it will be written over with ones and zeros an can be enabled while in Trash and opening the Preferences (Cmd+,) would assure you, that most people won't be able to recover the data, even with software like Data Rescue II (99$).
    So why do you think, someone will go trough all the trouble, and recover your web history?
    With software it costs money (or not, if the person is adequate enough to find a pirated version) or it will cost real money, if the HDD is given to a professional.

    It's your computer, no one else should have access to your user account (if you have accounts set up, and it is indeed your computer).

    Good luck.


    PS: I will also post this in you other thread, if it's okay. I need the posts desperately. :D
