    Default Best way to delete files off computer before selling?

    I want to keep my OS and programs on the computer when I sell it, but dont want anyone to recover my deleted programs. Is there a program that cleans the drive so that the files can not be recovered?

    I'm not sure if there is any software like that, you'd say there would be but i don't know. Did/do you save your data on a separate partition or not? If so you can just re-format that partition a few times, that should do it.
    What you could do is just delete all the data and fill up your hdd with unimportant data like movies or something, and delete it again. Once your data has been overwritten once it would be very hard if not impossible to recover it again.

    i do know there are some pay software that will basically rewrite the used sectors over and over so its nearly impossible to recover. But i dont tihnk vista has anything like that built in. Ubuntu has it built in and would be nice on Vista

    I think you should keep your HDD when selling your PC.
    It's the safest way.

    That is what i always do actually, just replace the hdd for a new one and use the recovery disks to re-install the notebook to it's original configuration. You can get a usb case for the old hdd and use it as an external hdd.

    Use Darik's Boot and Nuke program. This program is so good that the Department of Defense uses it on their computers when they want to permanently wipe an HD. You can even select their exact settings or select something with the level of security you want. Be warned, this process takes some time, about one day. I think CNET ran a video tutorial a little while which will help familiarize yourself with the program. Alternatively, there's an FAQ on Darik's website. Another warning, you will NOT be able to recover any data whatsoever once you execute the program. AGAIN YOU WILL NOT BE ABLE TO GET ANY DATA OFF OF IT.

    You could also just go the fun route and take out your HD, dip it in liquid nitrogen + hammer = good times. Or add flames.

    There are a few programs that do this. One is called Eraser, and you can find it here: http://www.heidi.ie/eraser/download.php or there is a command line tool called sdelete from sysinternals that can wipe free space or securely delete specific programs.

    ABSOLUTELY NOT!@! Formatting does NOTHING to erase data on the disk!

    The DoD has published a few standard erasing techniques that have been implemented by many programs. My guess is this program is simply one of those implementations. However, for modern hard drives, this is usually overkill. All you need to do is zero out the disk, or if you want to get really secure use some random data.

    You can read about the Gutman method here: http://en.wikipedia.org/wiki/Gutmann_method who is the guy who did a lot of work in this area.

    I believe Windows Washer has an option to create a low level formatboot disk and you can choose the level of format to make it pretty unrecoverable.
