4.2 Log Parameters
C141-C010 4-51
•
Data Underrun
Count of data underruns which occur during write operation when a buffer empty condition prevents
continued transfer of data to the media from the buffer.
The drive does not support this field due to a hardware limitation. Zero is always reported.
•
Data Overrun
Count of data overruns which occur during read operation when a buffer full condition prevents
continued transfer of data from the media to the buffer.
The drive does not support this field due to a hardware limitation. Zero is always reported.
