What is the best practice to remove all data in the disk?

If you want to securely remove the data, I recommend using a tool like

DBAN.

If you want to just wipe out the partition & boot sector for a clean reinstallation, dd'ing the disk with zero for a couple of Mbytes is more than enough.

I second that. Dban is the niftiest thing since sliced bread. Very handy tool, if a bit slow. But I guess that comes with the territory. 8-)
