If you can get a LiveCD of Linux or if you have access to a Linux system, the besz way is:

dd if=/dev/random of=/dev/<your hdd> bs=65536

for <your hdd> you need the respective device name. hda for 1st IDE Master for example.
This will fill your hdd with random numbers thereby totally erasing everything. If you do it twice there is practically no chance of recovering anything, not even for a Professional.

MHDD with ERASE command or FASTERASE using the security subsystem of the HDD itself.
Even more sure : erase the drive and selfscan it... (need special tools)

The second issue : if you don't have any specialized tool, MHDD with SCAN and REMAP function if bads are few.
If the problem gets serious, tell us what type of drive you have... probably need cutting zone or selfscan or lock entire track, but need specialized hw/sw tools.
