Submission + - Your DVDs will rot even if in ideal storage 2

AnalogDiehard writes: I've been making personal backup copies of software DVDs when I buy them. I use the backup and store the original in a cool dry place in protection sleeves, and I do not distribute or sell them. This is perfectly legal under US Copyright law U.S.C. section 117. More than once when I had replaced a computer at home, I found that the backup DVD no longer worked and had to make a new one. Just recently I pulled out the original DVD to make a new backup, and I was dismayed to find that no longer worked either. I checked my other original DVDs and found some that had never been pulled out since purchase had also went bad. It turns out that DVD rot is very real — even if your original DVDs are stored as optimally as possible, they will simply degrade to a worthless drink coaster even if not used. After many experiments I have yet to find a brand or blank media type that is reliable. Needless to say, I no longer rely on DVD media for backup.

Real computer scientists don't comment their code. The identifiers are so long they can't afford the disk space.
