"Zero filling removes the data on a HD 100%. This is especially useful in preventing data being stolen from your HD. After doing a zero filling, (apparently) no tool can retrive data from your HD and everything is permanently deleted. "

Thats simply not true, setting all the bits to zero is the least useful in preventing data being stolen from your HD, the best way is to override the data with random numbers, you actually have to make seven passes for the data to be securely removed. (i.e override the entire harddisk with random data 7 times)
