how to DEGENERATE Hdd

I tried google for a few hours, but it seems that all internet is about bad sector recovery, i'm out of ideas.
I mean - how HDD software decides and what it should send into controller board to force sector to turn electronicaly bad when a defect is found.

I'll try to explain myself better...
Now there is this device in your PC Computer. It is called Hard Disk. It's a little box in which you do store your porno. If there is no Hard Disk there is no porno. See how it is important?
Hard Disk is composed of "stuff". One element of "stuff" is a platter. On a platter "stuff" writes porno and reads it later. A platter is divided into magnetical segments called cylinders and sectors.
Hard Disk platter may and will become defective over time. As you will scratch your Audio CD-R's. In such case when you will write your porno, a middle of your porno may be written on defected area. For this not to happen, good guys wrote tons of software to scan for defective sectors and mark them as "Bad Sectors" to remove them for usage...
Now what i'm looking for is a method or software to mark sectors as "Bad" without them beeing defective in the first place.
