I am looking for two free disc tools:

1) a disc scrubber, to remove all traces of data from my hard drive

2) a disc clone tool, to copy one hard drive onto another.

If you don't get a response before then, bump this in about eight hours and I'll ask Fahim if he knows of anything.

It'll write zeroes to every sector on your drive once. (The pay version writes three times, and is thus DoD-compliant.) But it's slow.

I hear this one's a bit faster:

in response to a request for a disk scrubber by me.

I used the dban one and it worked fine, if slowly.

It allows you to make a boot floppy with a small Linux distro that wipes the disk. It worked very well, if slowly, for me.

Just download, burn, then boot a Knoppix CD.

It includes shred, which will handle the first: http://www.oreillynet.com/pub/wlg/6592?page=last&x-maxdepth=0

As for disc cloning, dd is your friend. Read the cloning an entire hard drive bit: http://www-128.ibm.com/developerworks/linux/library/l-knopx.html?ca=dgr-lnxw04Knoppix

I've used knoppix before, but since my drives are NTFS, I wasn't able to modify the drives at all.

Will that be a problem? It doesn't have to be, because I guess it won't be using the NTFS, but wiping the entire drive, partitions and all.

I personally would not use Linux tools on an NTFS partition but that's just me being paranoid about MS and their crazy Linux-hatred/paranoia [Razz] However, I do have a question, do you want a scrubber to wipe your full hard disk or a day-to-day shredder which wipes all traces of files that you delete off your hard disk? I haven't had the need for a full disk scrubber but I could look around - there should be something good (and free) around [Smile]

I just read about shred, and it says that it works no matter what type of partition it is.

On a related note, I heard that it's possible to access NTFS partitions from linux if you have it use one of the windows DLLS. Does anybody know how to do this with knoppix?

You should be able to mount NTFS partitions knoppix to at least read-only (its been a while). With doing anything but a mount.

Both shred and dd, when used on an entire disk, should work fine on NTFS. They both operate below the level of the filesystem, so it doesn't matter what filesystem is in place. The dd command mentioned there just copies every single bit it finds on the disk onto a new disk, in the same order.

Knoppix can mount NTFS partitions read only easily (and currently does so pretty much automagically, iirc), and can mount NTFS read/write as well (though there is a theoretical possibility of errors, the effectiveness has improved greatly in the past year or so).
