    how to completely wipe a hard drive?

    Someone told me that there is a command to completely wipe a hard drive? Something like cat dev 0 >/dev/sdb?? but that obviously doesn't work. Can anyone tell me the correct command to send 0's to a hard drive? Thanks...

    I know that rm -rf completely removes everything from your hard drive.
    Go to terminal and enter that code in. Don't forget to type "sudo" first.

    If I'm wrong, I'm a beginner so I apologize.

    dban is definately the way to go. I typically use the Ultimate Boot CD when I run dban. It is one of the many useful utilities that is included.

    You mean something like this?


    Code:
    dd if=/dev/zero of=/dev/hda

    If you want a really rhorough wipe, use dban.

    Re: how to completely wipe a hard drive?

    Its a long story really. The problem is its a 500GB drive that has become 136GB because of a bios issue moving the drive between computers with older bios. So, apparently the only way to get the drive to detect as being 500GB again is to totally zero byte it...formatting and partitioning don't work. It is always detecting as 136GB when it is actually 500GB...

    Ultimate Boot CD has a variety of disk wiping tools.

    I know Active Kill Disk has the option to 0 the drive completely (in fact, is default for the "trial" version).
