    Get a live CD distro of Linux
    pop it into the CD drive (if no cdrom, put one into the second hard drive chain to make sure the drive letters are right)
    at the prompt, as root, type
    dd if=/dev/random of=/dev/hda bs=512

    repeat at least 3 times for each drive. It will take a while.

    If you want a much faster, but less secure overwrite then:

    dd if=/dev/zero of=/dev/hda bs=512

    repeat that one 3 times for each drive. It will ba MUCH faster, but will only put zeros onto each part of the drive. Normal recovery tools will not be able to read it though.

    or, take the easy way. go here http://www.heidi.ie/eraser/download.php

    download the program and install on a windows machine. make the 'nuke boot floppy'. boot that floppy on the machine with the drive you want to wipe. go drink a beer, have some dinner, whatever to kill time until it's done.

    you won't need to repeat the process. one boot per drive is more than enough.

    I use Autoclave; it's included in Disk Utilities section of the Ultimate Boot CD.

    25 passes with that and even the NSA geeks cannot get anything useful from a HDD.

    Thank You MB-G26, However, I think that your response was more
    directed at the discontinuation of Autoclave, etal..in favor
    of (DBAN). With all due respect, I'd just like to know what
    buttons I have to push to clean my hard drive, short of
    attending a MS conference!

    I feel that i'm in the cyber equivalent of "what's the best
    9mm". I appreciate everyone's input, but we all don't speak
    cyber geek. Thank you.:(

    Edited to say that I appreciate Tech talk, but sometimes it
    get's cooked in the autoclave.

    Format c: /q works but everything is recoverable. Basically if you don't have any sensitive info on there, that will do it.

    Take a look at the "nice files" page section on www.lurkhere.com
    There's a reliable, well-thought-of data wipe program available for free (and spyware free) download there.
