The paper describes the indirect method of obtaining the information on wheel pair skidding. The method is based on using a special filtration scheme which filters the estimated resistive torque and highlights the signal which is proportional to wheel pair skidding. The work introduces as well the imitation modeling results. https://www.roneverhart.com/Western-Digital-Ultrastar-DC-HC530-WUH721414ALE6L1-0F31170-14TB-7-2K-RPM-SATA-6Gb-s-512e-SED-3-5in-Hard-Drive/
