The ideal way to get rid of your information recorded on a hard disk

Most of us sold, gifted, or got rid of an old computer after we got a new one.
But what do  we do with the old hard disk full of information, some of which might be dangerous?
This information can be recovered with some effort, and therefore, reaching the wrong place may be very harmful.
Scientifically, all formatting ways do not lead to an acceptable result, except an old and long way, which is a Low- level format, it is the only "guaranteed method until this time."
I find that the only reassuring way is to:

*- Remove the hard from the computer.
*- Put the hard disk on the table in which the circuit down.
*- Unscrewingthat fix the cover.
*- Remove the magnetic disk from its place.
*- Place the magnetic disk on a low fire.
*- Then get a sharp tool and make a few scratches tilted from the center of the magnetic disk to the circumference.
*- Try to drape the magnetic disk, so it can't be placed on a single surface.

Put a few lemon slices in the blender.
Add a little bit of lemon peel to it.
Add a few ice cubes to it.
Add a little sugar to the mixture, then some mint leaves.
Mix vigorously for three minutes.
Savor the mix and enjoy it after this effort just now your information is safe.
