You could also use 446 instead of 512. This will remove the MBR, but leave
the partition table intact, since the partition table is kept in the last 66
bytes. I use this to remove the MBR for lilo, grub, dos. A lot of people
suggest fdisk /mbr. Problem 1 need a dos/win disk. Problem 2 doesn't
really remove the mbr just replaces it with the dos one. Using 446 salvages
your partitions, but zeroes out the MBR.
