V linuxu na to mam skript:
#!/bin/bash
DEVICE=/dev/hdx
echo "Budu mazat zarizeni ${DEVICE}, az bude pripraveno stisknete ENTER"
read a
for k in 1 2 3
do
block=`expr $k \* 32`
echo "Zapisuji nuly ."`date`"..."
/bin/dd if=/dev/zero of=${DEVICE} bs=${block}k
echo "Zapisuji jednicky ."`date`"..."
/usr/bin/cat /dev/zero | /usr/bin/tr \\000 \\377 | \
/bin/dd of=${DEVICE} bs=${block}k
echo "Zapisuji nahodna data ."`date`"..."
/bin/dd if=/dev/urandom of=${DEVICE} bs=${block}k
done
echo "Zapisuji nuly ."`date`"..."
/bin/dd if=/dev/zero of=${DEVICE} bs=2k
exit 0

Velmi dukladny.
