16—Guard Band Error
Error Description: During normal operation, the
heads have moved into the inner or the outer guard
band area. If the servo system is in the process
of loading or unloading heads (for example: the
positioner is moving from the landing zone or to the
landing zone), the I/O processor will mask out the
guard band signals internal to the GASP gate array
and thus prevent a servo fault from occurring.
FN: 46—out.grd.bnd.—outer guard band fault
FN: 47—inn.grd.bnd.—inner guard band fault
Most Probable Cause: ECM, HDA
