so here are the actual command that you will have to run, 

dd if=/dev/zero of=/dev/hd? ; dd if=/dev/full of=/dev/hd? ; dd if=/dev/urandom 
of=/dev/hd?


is the addition of /dev/full sufficent ie /dev/zero alternated by /dev/full 
should do the trick ? ie write zeros and ones on the disk, followed by random 
writes. done 5 times should it be enought?
