    Default disposing of old CD-Rs of data

    from undergrad Uni work, I have a big box of them and I am planning on throwing a lot away as I no longer need them (from 2002-4!!!). I would like to make sure that the data on them is unrecoverable though, what is the best way to do this, as I will have probably about 200 of them going out!

    Not sure how to erase the data, though I expect breaking the CDs would work OK.

    Best wishes for many sales to all,

    Shredders that can handle paper, credit cards AND CDs are available.
    Complete destruction of the disc is the only 100% sure method of stopping a determined snooper.

    I believe a strong magnet totally corrupts all data, then the disks can bu used for various types of decor or art work

    For that many, get a shredder (ensure it is rated to cope with CDs). When you have finished...you'll have a shredder for other sensitive stuff.

    Other than that, physically damage them. Don't put them in a microwave (as some people suggest). Drill, saw, abrade, break, etc. (wear gloves and eye protection). Burn. Immerse in Ketone.

    CDs/DVDs do not work by magnetic field variation, they work by optical interference.

    3 to 1 ratio of Muriatic acid and water in a five gallon bucket, soak overnight. Then add 7 more parts water and wash your driveway with the liquid.

    Safety Glasses, eye, hand and arm protection will be advised along with staying away from the fumes. I have never melted that many cd's/dvd's so I'm not sure after soaking if you will end up with a massive clump of plastic or if they will liquify but they will be unreadable.
