From: chloe K <chloekcy2000 at yahoo.ca> > What is the best practice to remove all data in the disk? > ls fdisk ok or use dd Maybe something like (replace the ?): - fast but not secure: dd if=/dev/zero of=/dev/?d? bs=4096 - slow but more secure: dd if=/dev/zero of=/dev/?d? bs=4096 - n times slower but n times more secure: for ((i=1; i<=n; i++)); do dd if=/dev/zero of=/dev/?d? bs=4096; done JD
