    Zero Fill Hard Drive Before Fresh Install

    My project today was to do a Zero Fill on my hard drive
    and then do a fresh install of Hardy from a live CD, but
    before I get going I think I need to double-check. Measure
    twice and cut once, so to speak. Have I ignored something?

    By the way, I dual boot and the drive I want zero fill is
    the master.

    Thank you!!

    I don't understand the question.

    You want to zero-fill and then install hardy on a dual-boot machine. Isn't that essentially the same process as wiping and installing hardy, with a few extra steps for the zero fill? Seems like you should just do it.

    I don't think so. Linux seems pretty lazy when it finds a ext3
    partition. It certainly does not wipe the disk.

    In any case, I did a zero fill and then a fresh
    install. You can zero fill with linux. Run a
    live CD and in the terminal enter:

    Code:
    dd if=/dev/zero of=/dev/hda bs=1M
    It took about 1.5 hours for 120 GB.
