In a method for determining evaluation data for transmissions in vehicles, data is measured in the vehicle via sensors, the measured data is used to form intermediate data specific to the vehicle and then, from the measured data and the intermediate data, evaluation data is determined which is shown, stored or transmitted to a data collecting station. The mill scale is mixed with alien iron oxide and the resultant mixture is heated to a temperature of 200\xb0 C. The IF unit transmits video data decoded by a decode unit from a terminal. If multiple disks are equally ranked, one of the equally ranked disks is randomly chosen to be the spare disk allocated.
