Note: Because the beginning of tape is written to every time a tape is unloaded, this area of
the tape tends to wear sooner than the rest of the tape media's length. As a result, it is not
unusual to experience rewrites or ECCs at the beginning of tape. If these situations occur, the
predetermined thresholds can be exceeded early, but the percentage then drops below the
threshold as reading or writing moves further down the tape. To signal this, the error-alert LED
blinks when the error rates currently exceed the set values. It returns to a steady illumination
if, once exceeded, the error rate falls below the set value.
