This application discloses a hard disk drive using a self-resonant frequency band of a Voice Coil Motor far above its operational frequency band to predict Rapid Off Track events before its head stack assembly can deliver the disruption to the slider writing a track. A circuit board and/or an integrated circuit are disclosed in various embodiments to predict the ROT events using the self-resonant frequency band and/or to respond to the prediction to suppress the slider writing.
