6.1.4Conductive noise

The disk drive shall work without soft error degradation in the frequency range from DC to 20 Mhz injected through any two of the mounting screw holes of the drive when an AC current of up to 45 mA (p-p) is applied through a 50-ohm resistor connected to any two mounting screw holes.
