1. A method of monitoring transducer head health in a hard disc drive (HDD) comprising:
running a transducer health check at a first frequency;
running a data integrity check of data written by a write transducer embedded within the transducer head at a second frequency; and
responsive to a flag generated by the transducer health check indicating that a projected remaining life of the write transducer is below a threshold, increasing the frequency of the data integrity check to a third frequency.
