Security researchers have demonstrated an acoustic attack on hard disk drives (HDDs) that can make a computer crash and lead to file system corruption. They also demonstrated how a security camera was unable to record video with a similar attack. The attack has been named BlueNote.

I suppose SSDs are not affected in any way, given that they don’t operate with spinning magnetic disks.

It’s not really a mystery. Vibrations cause things to vibrate, which causes the heads to access the wrong sectors. If an operating system is reading important files, and the HDD reads the wrong sectors, the operating system will start doing unpredictable things with that incorrect data (unless the drive detects the error, and silently corrects it, which clearly isn’t the case).
