In a flexible diskette drive using a microprocessor for drive control functions, illegal conditions can be detected and compensated for or signaled to the user. During the product development phase of such products the problem can be noticed and corrected instead of overlooked until a serious field problem is caused by a particular user operation. An added benefit is that the fault condition of a malfunctioning file adapter will be signaled in the field even though the original design was good. The signal is conveyed via the reset action. This may for example consist of starting the program over and doing a reorientation of the read/write read to track 0/.
