Let’s say someone wants to destroy the contents of a large
number of cds. One way is to bend them such that they crack into
several pieces. But having 50+ cds, it would be a time consuming
way.
Other ways are:
1. Using penknife to scratch the surfaces of the cd
2. Using a lighter and have a naked flame burning the surfaces of
the cd
3. Formating the cds
Which way would be a sure way that people would not be able to
read the contents of the cds? and the least time consuming way?
Put them into a Microwave and set it to 15seconds high.
But I only tried it on ONE CD.
