Damaging Hard Drives with an Ultrasonic Attack

Playing a sound over the speakers can cause computers to crash and possibly even physically damage the hard drive.

I don’t know why this is news. My university friends and I knew this in the early 90’s, and I think it was common knowledge at the time. Did the sound have to be ultrasonic? No. But we knew a loud party could screw up the hard drives we had in our desktop computers. As low end bass became more and more of a thing, it was even easier to see the connection.

We played audio cassettes at parties to deal with this very issue.
