Figure 65. concluded
The drive will attempt to read data after a seek before the head has fully settled on track. This is done to
aid performance. However as a result there is a high incidence of error recovery invoked which normally
uses ECC or a retry to recover the data. As a consequence of this an error recovered by a single retry is
not reported by the error counters.
Additionally the drive does not report data recovered by ECC on the fly as it is not possible to distinguish
between ECC errors caused by reading before settling and other causes.
