Re: totally wiping harddisk using Knoppix

[Wiping] 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.

Why may the disk be unusable thereafter?
Can't you just create new partitions again
and format them?
