Re: totally wiping harddisk using Knoppix

Yes dd sounds like the one.

Whats the command line ?

The whole hard disk?
dd if=/dev/zero of=/dev/hda bs=1M
and then wait. That wipes /dev/hda completely-- including all formatting
info, the MBR, etc. The disk may be unuseable thereafter.
If you just want to wipe a partition, use /dev/hda6 let
us say.

If you want to use the disk again, I would use fdisk to erase all the
partitions, and make one partition of the whole disk space and then do
dd on that partition.

I will remove all the other harddisks IDE leads just in case.

Now I need a good lowlevel command to wipe the darn thing.

How thoroughly? dd will fill it with zeros. 'Secure-delete' and 'wipe'
will render the data unrecoverable by anyone who is not prepared to spend
stupendous amounts of money.
