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
Oops, for the slow procedures, it is /dev/random instead of /dev/zero...
