No, really, I’m serious.
I back up the 10 gig or so of personal files on my hard drive with a program that writes them to 650 megabyte .ZIP files. Then I burn the .ZIP files to CD-Rs.
The problem is that now I have hundreds of CD-Rs of old backup sets that I no longer need. But I don’t want to just toss them into the trash because they are plain old unencrypted .ZIP files that could end up in the hands of my enemies (FNORD).
So I’m trying to find a reliable method to quickly render CD-Rs unreadable on casual use (if the CIA really wants to capture my data they’re going to — I just want to make sure the geek down the street couldn’t pilfer my trash and recover the data).
Any ideas?
