It's fall and we have less space in our home. The next three posts will show step-by-step methods of destroying the hard drives completely so one can ever read them again. 

This post shows the five steps of destroying a hard drives and making book ends. Making absolutely sure that the disk is not read ever.


This disk is from a VAIO Sony Computer and has Service Business data. The case around it had been removed and only the silver disk is shown. 

This picture shows what it looks like after the disk has been hit several times by a metal sledge. Notice that the interior can still be read. Just beating the disk will not stop thieves from reading the disk. 

Using a sharp metal chisel or any sharp object and making sure that it the scratch start at the beginning of the disk and goes the the core of the disk will stop  the reading process. But here I went further.
My next step was to use pliers to bend the disk and hammering it flat to make book ends.

This picture shows the use of a 1/4 inch wood chisel scratching the surface of the metal data disk.

After each side both top and bottom were scratched then the use of a claw hammer and a metal sledge.

On the left is the old hard drive pounded flat and scratched all over. The case and screws  are made of aluminum and can be recycled. Do not be tempted to recycle the metal disk. Throw that in the trash can area. The next post will address the PCB board.
