Fujitsu MAP3147, MAP3367 Write error count, Write errors recovered without delays Page 02, Code

Parameter Data Formats

•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.
