What hard disk disposal method would be used to physically destruct the hard disk rendering it into thousands of metal pieces?

Shredding is a type of disk disposal method using physical destruction. Shredding a hard disk is similar to shredding a piece of paper; using a more powerful shredder. The hard disk is inserted into the shredder and is then reduced to tiny shards of metal that can then be recycled. This
will permanently destroy the hard disk.

Drilling holes through the hard disk is another form of physically destroying
the hard disk. Although this may not be the best method, or have the effect as shredding a hard disk, it will still make it inoperable.
Drilling the hard disk will not render the hard disk into thousands of metal pieces.

Degaussing is a sanitizing method used to completely remove data from a hard disk.
It removes the data by applying a strong, constant magnetic field to the hard disk. It will not render the hard disk into thousands of metal pieces..
