Hard Disk Drives (HDDs) fail to spin up due to excessive stiction between the slider and disk. 'Torque Amplification' is a microcode based procedure that is executed when the HDDs fail to start up normally. It is a complex that is used to drive the spindle motor in order to amplify the available torque via mechanical resonances.
