My desktop computer developed a really annoying vibration-induced buzzing sound a few months ago after I added some hard drives to it. It was one of these where it’d be more or less quiet, and then all of a sudden a buzzing would start. If you tapped the case, it often made the buzzing stop.

One by one I went through my components, and the day before yesterday I finally identified the guilty party, one particular HDD. Currently I have the case open and a piece of cardboard jammed under the drive in its tray. The computer has not buzzed since I did that, so it looks to me like securing that drive better will finally end this madness-inducing sound.

Wild that it takes so long to track down something like this and figure out what to do about it.
