WARNINGS
     Due to a hardware limitation in many floppy drives, the  act
     of checking for media causes mechanical action in the floppy
     drive.   Continuous polling of the floppy drive  will  cause
     the  drive  to  wear out. It is recommended that polling the
     drive only be performed during periods of high use.
