There is a repeated note (or sound effect) in the song which has a pitch which sweeps through 7200 Hz. In fact, it is reminiscent of a kind of sound that can occasionally emanate from a failing drive which spins at that rate. I wonder if they got the "5400 RPM" detail wrong?
I don't think the rotational speed of the drive is that relevant; the resonance that was being excited is certainly different as otherwise the drive would've excited it via its own rotation.
