Hello,
How to wipe a HD, please?
Wipe as in?
If you want to destroy partition table info and remove any boot loaders from MBR (assuming you want to wipe /dev/hda):
dd if=/dev/zero of=/dev/hda count=10
If you want to zero out entire disk (might take long time, depending on the size of the disk):
dd if=/dev/zero of=/dev/hda
If you want to delete information so that some university student can't recover it using equipment from the university lab, there are some commercially available applications that will overwrite entire disk several times with specially designed patterns.
If you want to delete information so that NSA can't recover it, use sledge hammer and don't stop until you make disk plates into fine dust. However, if NSA is after you, they already have the information, so it is pointless to destroy your HD.
