Drives that experience failure may report certain values as null via the Redfish API. If the reported capacity is affected, this led to a crash in the "Drive" service:

TypeError (unsupported operand type(s) for /: 'NoneType' and 'int')

Now the null capacity values are treated the same as completely missing capacity: The reported drive size is 0GB.
