Hopefully this can become an authoritative thread on the subject when all’s said and done. What I am trying to do is simple - I want to destroy media. I have specific requirements. Read on.
I recently completed “transcoding” a collection of CD-Rs to DVD media. They numbered 150+ and I now have 22 DVDs containing the same data. I wish to destroy the CD-R discs beyond repair. They do not contain ultra-sensitive data, so they don’t have to be beyond the repair capabilities of governments, but if it’s all the same I may as well destroy them so that nobody in the world can recover the data. However, this is not a requirement - I am flexible on this.
I have read various ideas on the subject. A lot of them are anecdotal=impractical - i.e. putting them in the microwave. Here are my real-world requirements:
[li]must be ecologically friendly - the method must not create a significant amount of contaminants, such as chemical dust, etc. I do not wish to further contaminate our environment.
[/li][li]must be safe - the method must not endanger neither me nor my property. microwaving the discs is absolutely out of the question, as is setting them on fire, boiling them, etc. I do not want to inhale dust from pulverizing the discs, and so on. my health and well-being is priority #1.
[/li][li]must work on bulk quantities - when I’ll be ready to proceed, I will probably have close to 300 disks. obviously, I do not have the time nor patience to apply the method to each disc individually.
[/li][li]must be relatively inexpensive - I will buy a drill bit, a small saw, etc., but I will not spend a lot of money on specialized equipment.
[/li][li]must at the very least render the discs useless to anybody short of a data-recovery shop. ideally, the method should render the discs useless even to world governments.
So there it is. I await your input. I already have some ideas, which I’ll post after I get some feedback.
