Bad news if this is dd.

N+m records in

N - blocks read succesfully
M - partial blocks read + plus failed blocks read

Similar for output.

My guess is your data source is not keeping up with your output.  I
think it is conv equal noerror,sync that causes dd not to wait on
partial reads and instead to zero out partial buffers.
